Answers

Answer 1

A straight upward thrown ball takes 10 seconds to complete its up-and-down circular journey. Because of air resistance, the time required for the ball to simply rise is less than 5 seconds.

What is air resistance?

Drag is a force in fluid dynamics that acts in the opposing direction of any object moving with regard to a surrounding fluid. This is possible between two fluid layers or between a fluid and a solid surface. Air resistance is a force created by air. When an item moves through the air, the force operates in the opposite direction. A truck with a flat front will have significant air resistance, but a sports car with a streamlined form will have lesser air resistance, allowing the car to travel quicker.

find the amount of work wba done by the electrostatic force on the charged particle as it moves along the straight path from b to a.

Answers

The amount of work done by the electrostatic force on the charged particle as it moves along the straight path from B to A is equal to the force of the electrostatic field, multiplied by the displacement of the particle along the path.

Mathematically, this can be represented as WBA = F * d, where F is the electrostatic force and d is the displacement of the particle.

Work is a concept used in physics to describe the transfer of energy from one object to another. It is defined as the force applied over a distance and is usually measured in joules (J). When a force acts on an object, it causes the object to move or to change its shape, and this energy is transferred from the force to the object.

Work can be positive, in which case the object gains energy, or negative, in which case the object loses energy. Work can also be done on an object without it actually moving, such as when a force is applied to stretch or compress the object.

the plate separation is now increased to a distance of 2d. which of the following correctly describes the change, if any, of the voltage across the capacitor, the electric field between the plates, and the energy stored in the capacitor?

Answers

The correct answer is: 1

Voltage does not change Electric field does not change Energy does not change

The following changes occur when the plate spacing of a capacitor is raised to a distance of 2d:

The voltage across the capacitor is as follows: Because V = Q/C, where V is the voltage, Q is the charge on the plates, and C is the capacitance, the voltage across the capacitor lowers. The capacitance and consequently the voltage drop as the plate spacing rises.

The electric field between the plates is as follows: Because E = V/d, where E represents the electric field, the electric field between the plates diminishes. The electric field reduces as the voltage falls (as explained above).

The energy stored in the capacitor diminishes because the energy stored in a capacitor is determined by U = (1/2)CV2, where U is the stored energy and C is the capacitance. The energy stored in the capacitor diminishes as both the voltage and capacitance drop.

When the plate spacing of a capacitor is extended to 2d, the capacitance falls, causing the voltage across the capacitor and the electric field between the plates to decrease. As the voltage drops, so does the amount of energy stored in the capacitor. As a result, none of the characteristics (voltage, electric field, or energy) stay constant.

What is Torque?

Torque can be defined as the rotational equivalent of the linear force. Torque is also referred to as the moment of any force. Torque represents the capability of a force to produce change in the rotational motion of the object.

I = mR²/ 2

As we already know, kinematics equation is:

ωf² = ωi² + 2αΔQ

Therefore, α = (ωf² - ωi²)/ 2ΔQ

Here, ωf = 3.49 rad/s, d = 30.5 cm

ωi = 0, m = 0.270kg

d = 30.5 cm

R = d/2 = 30.5/ 2 = 15.25cm

R = 15.25 × 10⁻² meters

τ = Iα

τ = [(0.270 × (0.1525)²]/2 × [(3.49)² - (0)²/ 2×1.40×2π]

Answers

The current to the right is -725.9988 mA and this means that it is flowing in the opposite direction to the left.

What is current?

Electric current is described as a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space which is measured as the net rate of flow of electric charge through a surface or into a control volume.

Current = Charge x Rate of flow of charges

Rate of flow of charges = Total rate of flow of negative charges - Total rate of flow of positive charges

The total rate of flow of negative charges is 362 x 10^6 ions per minute and the total rate of flow of positive charges is 5.83 x 10^2 ions per minute.

Rate of flow of charges = 362 x 10^6 - 5.83 x 10^2 = 361.9994 x 10^6 ions per minute

And the charge on each ion is -2e

Therefore, the current can be calculated as:

As a result, the energy lost by the field in this operation equals ε_0 * A * dd^2 / d.

What is  electrostatic force?

Non-contact forces, such as electrostatic forces, pull or push on things without touching them. When certain materials are rubbed together, a phenomenon known as 'charge' is transferred from one surface to the other. Charged items pull on uncharged things and can push or pull on charged objects.

Here,

(a) The work done by electrostatic forces when the plates move closer together by an infinitesimal distance is given by:

W = - dQV = - dQ * (V2 - V1)

where dQ is the change in charge on the plates, and V is the voltage across the plates. The voltage can be related to the electric field between the plates and the plate separation by:

V = Ed

where d is the plate separation. Substituting this into the equation for work, we get:

W = - dQ * (Ed2 - Ed1) = - dQ * E * dd

Since the change in charge on the plates is proportional to the change in separation, we can write:

dQ = C * dd

where C is the capacitance of the parallel-plate capacitor. Substituting this into the expression for work, we get:

W = - C * E * dd^2

Finally, using the relationship between the electric field and capacitance for a parallel-plate capacitor:

E = ε_0 * A / d

where ε_0 is the vacuum permittivity and A is the area of the plates, we can rewrite the expression for work as:

W = - C * ε_0 * A * dd^2 / d^2 = - ε_0 * A * dd^2 / d

(b) The energy lost by the field in this process can be calculated as the work done by the electric forces, which is given by:

americium-241 is a radioactive isotope used in household smoke detectors. it decays by alpha decay. which of the following describes the properties of this radiation?

Answers

The radioactive isotope americium-241 decays by alpha emission in one popular variety of home smoke detector. Due to their charge, the alpha particles generate a modest electrical current.

Why are americium-241 smoke detectors used?

Ionization chamber smoke detectors' americium-241 causes the air in the detecting chamber to conduct electricity. Smoke disrupts the electrical current in the sensing chamber when it enters, sounding the alarm on the smoke detector.

What occurs during americium-241's alpha decay?

An atom of americium-241 will emit an alpha particle on its own. Two protons and two neutrons joined together make up an alpha particle, which is the same as a helium-4 nucleus. The americium-241 atom changes into a neptunium-237 atom when it emits the alpha particle.

Which of the following substances will undergo the largest temperature change upon the addition of 100 J of heat?lead (c = 0.128 j/g°C) iron (-0.449j/g°C)copper (0.385 j/g°C)silver (c = 0.235 j/g°C)aluminum (c = 0.903 j/g°C)

Answers

The substance that will experience the largest temperature change when adding 100 J of heat is lead.

The formula that relates heat to temperature change  is

Q = m × c × ΔT

m = mass (grams)c = specific heat capacity (J/g °C)ΔT = temperature change (°C)Q = heat (J)
Q = 100 J

Suppose the mass of each substance is 100 grams

Lead
c = 0.128 J/g °C
ΔT = Q ÷ (m × c)
ΔT = 100 ÷ (100 × 0.128)
ΔT = 100 ÷ 12.8
ΔT = 7.81 °CIron
c = 0.449 J/g °C
ΔT = Q ÷ (m × c)
ΔT = 100 ÷ (100 × 0.449)
ΔT = 100 ÷ 44.9
ΔT = 2.23 °CCopper
c = 0.385 J/g °C
ΔT = Q ÷ (m × c)
ΔT = 100 ÷ (100 × 0.385)
ΔT = 100 ÷ 38.5
ΔT = 2.60 °CSilver
c = 0.235 J/g °C
ΔT = Q ÷ (m × c)
ΔT = 100 ÷ (100 × 0.235)
ΔT = 100 ÷ 23.5
ΔT = 4.26 °CAluminum
c = 0.903 J/g °C
ΔT = Q ÷ (m × c)
ΔT = 100 ÷ (100 × 0.903)
ΔT = 100 ÷ 90.3
ΔT = 1.11 °C

The biggest temperature change to the lowest is lead, silver, copper, iron, and aluminum.

For a certain experiment;, you must provide the kinetic energy of some object with its uncertainty: (The equation for kinetic energy K = Emv? where m is the mass of the object and v is the object's speed ) To do this, you first measure the mass of the object to be 0.015 kg Due to the limits on precision for mass using scale; you can only measure the mass of an object within an uncertainty of 2.4 grams (so Om-2.4x10 3 kg): In this same experiment; you measure the speed as 10 m/s, but you can only measure the speed with a precision Ov-1.2 m/s_ Hence; the mass and speed you report are m 15 +2.4 g and 10+1.2 m/s, respectively. How would you report the kinetic energy using the error propagation formula given in the introduction (assuming the speed and mass measurements are independent of each other)? Hint; the derivative of kinetic energy with respect to mass dk dm and the derivative of kinetic energy with respect to dK speed MU. (Fll in the blank) 0.75

Answers

The kinetic energy is calculated as K = 0.75 J.

What role does the error propagation formula play in kinetic energy measurement?

Because it enables the determination of the uncertainty in a physical quantity based on the errors in the measurements used to determine it, the error propagation formula is a crucial tool in physics investigations. The formula calculates the uncertainty in the kinetic energy of an object by accounting for the uncertainty in the mass and speed measurements of the object. In order to account for any limitations in precision in the measurement instruments used, this enables a more accurate representation of the object's kinetic energy. The error propagation formula offers a mechanism to express the uncertainty in a physical measurement and contributes to the precision of scientific findings.

Using error propagation, the uncertainty in kinetic energy is calculated as:

ΔK =[tex]\sqrt{((dK/dm)^2 \times m^2 + (dK/dv)^2 \times v^2)} \\=\sqrt{(0.5 * v^2)^2 \times (2.4 x 10^-3 kg)^2 + (m \times v)^2 \times (1.2 m/s)^2) }= 0.05 J.[/tex]

Therefore, the reported kinetic energy and its uncertainty is 0.75 ± 0.05 J.

What is velocity?

Velocity is a vector representation of an object's or particle's displacement with respect to time. The meter per second (m/s) is the standard unit of velocity magnitude (also known as speed). Alternatively, velocity magnitude can be expressed in centimeters per second (cm/s). The direction of movement of the body or item is defined by velocity. Speed is fundamentally a scalar number. Velocity is, in essence, a vector quantity. It is the pace at which distance changes. It is the displacement rate of change. The velocity of an object is the rate at which its location changes in relation to a frame of reference and is a function of time. Velocity is a statement of the speed and direction of motion.

if you take a super bouncy ball and drop it from a height of 5m, where does it get the energy to bounch up from the groyund

Answers

The energy that allows a super bouncy ball to bounce up from the ground after being dropped from a height of 5m comes from the potential energy that was stored in the ball when it was elevated.

When the ball is dropped, it gains kinetic energy as it falls, and when it strikes the ground, that kinetic energy is transformed into other forms of energy, including thermal and elastic energy. The elastic energy stored in the ball's compressed material then pushes it back up into the air, converting back into kinetic energy as it rises and then potential energy as it reaches its peak height. The ball continues to lose energy to thermal and other forms, causing it to eventually lose enough energy to stop bouncing.
