According to the question, the speed of the boat in still water is 6 mph.

What is speed?

Speed is a measure of how quickly an object or person moves or travels. It is typically measured in units of distance per unit of time, such as meters per second, miles per hour, or kilometers per hour. Speed can also be expressed as the time it takes to cover a given distance, such as the time it takes to travel one mile or one kilometer.

The speed of the boat in still water can be calculated using the formula V = (D1 + D2) / (T1 + T2), where V is the speed of the boat in still water, D1 is the distance traveled downstream, D2 is the distance traveled upstream, T1 is the time it took to travel downstream, and T2 is the time it took to travel upstream.

In this case, D1 = 6 mph × 3 hours = 18 miles, D2 = 6 mph × 5 hours = 30 miles, T1 = 3 hours, and T2 = 5 hours.

Plugging the values into the formula, we get V = (18 + 30) / (3 + 5) = 48 / 8 = 6 mph.

Therefore, the speed of the boat in still water is 6 mph.

Because of the change in the configuration of the wire, there is a bigger difference in resistance when connecting to the center terminals of a potentiometer.

Slider potentiometers, also known as slide-pots, are designed to vary the value of their contact resistance by a linear motion, and as such, the position of the slider contact and the output resistance have a linear connection. When we turn the knob on a potentiometer, the resistance changes linearly or logarithmically. The taper refers to how the resistance varies. Turning a knob a specific amount changes the resistance by a fixed amount regardless of the location of the knob in a linear taper potentiometer. When connected to the central terminal, the change in metal configuration also leads to the resistance difference in addition to the above stated reasons.

The intensity level of the infrasound 10 km from the source is 62.41 dB.

Low-status sound refers to sound waves having a frequency below the threshold of human audibility, also known as infrasound (generally 20 Hz). Hearing increasingly becomes less sensitive as frequency decreases, hence infrasound needs to have a powerful enough sound pressure for people to be able to hear it. Although many parts of the body may be able to detect infrasound vibrations at higher frequencies, the ear is the primary organ for hearing low-frequency sounds.

There are some uses for the term "infrasonics," which examines sound waves below 20 Hz and up to 0.1 Hz (and rarely to 0.001 Hz). Monitoring earthquakes and volcanoes, as well as mapping underground rock and petroleum deposits, are all done in this frequency range.

The intensity level of a sound decreases with the square of the distance from the source. So, the intensity of the infrasound 10 km from the source will be:

100 dB - 20 log (10 km / 5.5 m)

= 100 dB - 20 log (1818.1818)

= 100 dB - 37.59 dB

= 62.41 dB

Answer:

539 N

Explanation:

The force of gravity (also known as weight) on an object can be calculated using the formula:

F = m * g

where F is the force of gravity, m is the mass of the object, and g is the acceleration due to gravity.

For a 55 kg person on the surface of the earth, the acceleration due to gravity is approximately 9.8 m/s^2. Therefore, the force of gravity can be calculated as:

F = 55 kg * 9.8 m/s^2 = 539 N

So, the force of gravity on a 55 kg person on the surface of the earth is approximately 539 N.

The pot will radiate 16 times more heat per second when hot compared to when it was at room temperature.

The amount of heat per second radiated by a pot depends on its temperature and surface area, as well as the emissivity of its surface. The formula for the heat radiated by a black body (an idealized object that perfectly absorbs and emits radiation) is given by the Stefan-Boltzmann law:

Q = σ * A * T^4

where Q is the heat radiated, σ is the Stefan-Boltzmann constant, A is the surface area of the pot, and T is the temperature in kelvins. Doubling the temperature of the pot increases its heat radiation by a factor of 2⁴ = 16.

So, theoretically, if the pot is a black body, it will radiate 16 times more heat per second when hot compared to when it was at room temperature.

The height of the cliff from which the stone was dropped is approximately 266.667 meters.

Where h is the height of the cliff, v_0 is the initial velocity (0 m/s), a is the acceleration due to gravity (9.8 m/s^2), and t is the time it took for the stone to fall to the ground.

Since the final velocity of the stone is given (72 m/s), we can use the equation:

v_f^2 = v_0^2 + 2 * a * h

Rearranging the equation and substituting the values of v_f and a:

h = (v_f^2 - v_0^2) / (2 * a)

= (72^2 - 0^2) / (2 * 9.8)

= (5184) / 19.6

= 266.667 m

Velocity is a measure of the rate of change of an object's position with respect to time. The magnitude of velocity is a measure of how fast an object is moving, while its direction indicates the direction of motion.

The unit of velocity is meter per second (m/s), which means the rate at which an object is covering distance in a given direction. The velocity of an object can be calculated using the formula v = Δx/Δt, where Δx is the change in position and Δt is the change in time.

An object can have constant velocity, meaning its speed is the same at all points in time, or its velocity can vary, such as when it is accelerating or decelerating. The velocity of an object can also be negative, indicating that it is moving in the opposite direction.

The location where the net electric field is zero is not a finite distance from the positive charges in this situation. The electric field due to each positive charge points radially away from the charge and the electric field due to the negative charge points radially towards it.

The net electric field is the vector sum of the electric fields due to all the charges, and it will not be zero anywhere in space since the positive charges and negative charge are not symmetrically placed.

The electric field at any point in space is defined as the force per unit charge experienced by a test charge placed at that point. In the given situation, the electric field due to the four positive charges will point radially away from the charges and will have a magnitude that decreases with increasing distance from the charges. The electric field due to the negative charge will point radially towards it and will have a magnitude that also decreases with increasing distance from the charge.

When these electric fields are combined to form the net electric field, the resulting field will not be zero anywhere in space since the positive charges and negative charge are not symmetrically placed.

A toy ball that is advertised to "bounce perfectly elastically" off hard surfaces means that the ball will rebound from a surface with the same energy it had before it hit the surface. In other words, the ball will lose no energy due to inelastic deformation.

Elasticity is a property of materials that refers to their ability to return to their original shape after being deformed by an applied force. When a material is deformed elastically, it experiences a restoring force that is proportional to the magnitude of the deformation.

The elasticity of an object can be determined experimentally by applying a force to the object and measuring the resulting deformation. There are several methods for doing this, depending on the type of object and the conditions under which it is tested.

To find the height of the fence, we need to find the final height of the ball after it was hit and then subtract the height of the fence.The final height of the ball can be found using kinematic equations. Using the initial velocity, acceleration due to gravity, and time elapsed, we can find the final height of the ball:h = vi * t + 0.5 * a * t^2whereh = final height

vi = initial velocity (0, since it was hit from ground level)

t = time elapsed (3.0 s)

a = acceleration due to gravity (-32.2 ft/s^2)Substituting the values,h = 0 + 0.5 * -32.2 * (3.0)^2 = 45.3 ftNext, we need to find the height of the ball 2.5 seconds after it reached its maximum height.Using the same kinematic equation,h = vi * t + 0.5 * a * t^2whereh = final height

vi = initial velocity (0, since it was at its maximum height)

t = time elapsed (2.5 s)

When a battering ram strikes a wall, it creates a type of mechanical wave known as a pressure wave or a shock wave.

Pressure waves are created by the transfer of energy through a medium, such as a wall or the air, as a result of a sudden change in pressure. The energy from the battering ram creates a compression wave that moves out from the point of impact and spreads throughout the medium. This type of wave is different from transverse waves, such as light or radio waves, which move perpendicular to the direction of the wave's motion, or longitudinal waves, such as sound waves, which move parallel to the direction of the wave's motion. The pressure wave created by the battering ram is an example of a longitudinal wave that moves through the medium, transmitting the energy from the ram to the wall.

The required distance between the two charges is r ≈ 0.098 km.

The force of attraction between two point charges is given by Coulomb's law:

F = k * q1 * q2 / r^2

where

F is the force of attraction (in N)

k is the Coulomb constant (8.987551787 x 10^9 Nm^2/C^2)

q1 and q2 are the magnitudes of the charges (in C)

r is the separation between the charges (in meters)

Setting the force equal to the weight (650 N) and solving for r, we get:

650 = k * 1.0 C * 1.0 C / r^2

r = [tex]\sqrt{\frac{k * 1.0 C * 1.0 C}{650N} }[/tex]

Converting r to kilometers:

r = √(k * 1.0 C * 1.0 C / 650 N) / 1000 m/km

r = √(8.987551787 x 10^9 Nm^2/C^2 * 1.0 C * 1.0 C / 650 N) / 1000 m/km
