Answer:
Explanation:
To find the resultant of two forces when given an angle, you can use the two-dimensional vector addition method. Here are the steps to follow:
Represent each force as a vector. The magnitude of each vector should be equal to the magnitude of the force, and the direction of each vector should be equal to the direction of the force.
Place the vectors on a coordinate plane with their tails at the origin and their tips pointing in the direction of the forces.
Find the x and y components of each vector using trigonometry. For example, if the angle between the x-axis and the vector is θ, then the x-component of the vector is equal to the magnitude of the vector times cos(θ) and the y-component of the vector is equal to the magnitude of the vector times sin(θ).
Add the x and y components of the two vectors to find the x and y components of the resultant vector.
Use the Pythagorean theorem to find the magnitude of the resultant vector. The magnitude of the resultant vector is equal to the square root of the sum of the squares of the x and y components.
Find the direction of the resultant vector by finding the inverse tangent (tan^-1) of the ratio of the y-component of the resultant vector to the x-component of the resultant vector.
The final result is the vector that starts at the origin and ends at the point determined by the x and y components of the resultant vector, with a magnitude equal to the magnitude of the resultant vector and a direction equal to the direction of the resultant vector.
By using this method, you can find the magnitude and direction of the resultant of two forces given an angle between them.
If a competitive inhibitor is present in an enzymatically catalyzed reaction, then:
A. Km↑ & Vmax↓
B. Km↓ & Vmax↑
C. Km↑ & Vmax is same
D.Km is same & Vmax ↓
If a reverse transcriptase is present, Km and Vmax in a catalytically concept goes will be equal.
What constitutes a good inhibitor?Here are four examples of medications that block enzymes: irreversible inhibitors like Acyclovir, which target the viral DNA-copying enzymes, are used to treat herpes. competitive inhibitors, such methotrexate, which treats bacterial infections as well as cancer. depression with non-competitive inhibitors like Trazadone.
An agent that challenges the substrate for the enzyme's active site is known as a competitive inhibitor. This response is often reversible.
The source concentration at which reaction is accelerating at half its maximal pace is known as the Michaelis Menten constant. It shows the enzyme's affinity for its substrate. Low Km denotes a strong affinity, while high Km denotes a low affinity.
A negative feedback system will increase Km by lowering the substrate's propensity to adhere towards the enzyme. At high substrate concentrations, the substrate outperforms the inhibitor, maintaining the reaction's Vmax.

if we triple the temperature and double the volume, what would the new pressure of the system be?
The pressure will increase by 3/2, or 50% when the volume is doubled and the temperature is tripled.
When the temperature is tripled, what happens to the pressure?The pressure rises as the Kelvin temperature rises. The relationship between the two amounts is direct proportionality. The pressure of the gas will triple when the Kelvin temperature is tripled.
How does volume change when it is doubled?So, doubling the volume will be equivalent to reducing the pressure. If you apply reasoning to it, this also makes sense. Gas will spend less time pressing against the container walls if it has more room to move around in.
How does rising temperature affect pressure?The average kinetic energy and the velocity of the gas particles striking the container walls both rise as the temperature rises. As the temperature rises, the pressure must as well since pressure is the force the particles per unit of area exert on the container.

how many electrons must be transferred from one to the other so that, when released, they each initially accelerate toward the other with a
When two charged particles, such as electrons, are discharged, their acceleration depends on their charge and the distance between them.
What is acceleration?In mechanics, acceleration is defined as the rate of change of an object's velocity with respect to time. Vector quantities are accelerations. The orientation of an object's acceleration is determined by the orientation of its net force. The rate of change of velocity is defined as acceleration. Acceleration usually indicates that the speed is changing, however this is not always the case. When an item goes on a circular course with a constant speed, it is still accelerating since its velocity direction changes. An object's velocity might fluctuate due to an increase or decrease in speed or a change in direction of motion. A falling apple and the moon orbiting the earth are two instances of acceleration.

how does the magnitude of the work done on the system compare to magnitude of the net heat entering the system?
The magnitude of the work done on a system and the magnitude of the net heat entering the system are both forms of energy, but they represent different types of energy transfer.
Work is done on a system when an external force causes a displacement of the system. This can result in a transfer of energy to or from the system, depending on the direction of the displacement and the force. The magnitude of the work done on the system is given by the product of the force and the distance over which it acts.
On the other hand, heat is a form of energy that is transferred from a hotter object to a cooler object. It is related to the random motion of particles within a substance and is transferred from areas of higher temperature to areas of lower temperature.

a golf ball of mass 0.043 kg is hit off the tee at a speed of 41.8 m/s. the golf club was in contact with the ball for 5.13 ms. find the impulse imparted to the golf ball.
When a golf ball of mass 0.043 kg is struck off the tee at a speed of 41.8 m/s, the impulse given to the golf ball is 1.78 Ns.
What is force?A force is an effect in physics that may modify the velocity of an item. A force can cause a mass item to change its velocity, or accelerate. Intuitively, force may be characterized as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Here,
The impulse imparted to the golf ball can be calculated as the product of the force applied and the time of contact:
impulse = force * time
Since force is equal to mass times acceleration, we can write:
impulse = m * a * t
where m is the mass of the ball (0.043 kg), a is the acceleration imparted by the club, and t is the time of contact (5.13 ms).
Since the time of contact is short, we can assume that the acceleration is constant, so we can use the equation for impulse-momentum to find the acceleration:
impulse = m * Δv
where Δv is the change in velocity of the ball.
Since the ball starts at rest, its initial velocity is 0 m/s and its final velocity is 41.8 m/s, so Δv = 41.8 m/s.
Substituting the given values into the equation, we get:
impulse = 0.043 kg * 41.8 m/s = 1.78 Ns
So, the impulse imparted to the golf ball is 1.78 Ns when a golf ball of mass 0.043 kg is hit off the tee at a speed of 41.8 m/s.

The speaker's power output is P = 4 * pi * r*2 * I = 4 * pi * 17*2 * 10*10.7 * I0 if the sound pressure level is 107dB at a distance of 17m.
How is the volume of a sound measured?A sound's intensity is calculated by dividing its power, expressed in Watts, by the square meters it covers. The intensity of any given sound is related to the intensity at the hearing threshold by the loudness of the sound. Decibels are used to quantify it (dB).
The following equation describes the relationship between distance (r), sound intensity level (L), and sound intensity (I):
L = 10 log10 (I/I0), where I0 denotes the reference intensity (10^-12 W/m^2) and I is the intensity of the sound wave at a distance of r from the source.
Finding the strength of the sound wave at a distance of 17 meters is necessary before applying the power formula (P), which is represented by:
P = 4 * pi * r^2 * I
To find I, we can rearrange the intensity equation as follows:
I = 10^(L/10) * I0
Putting the values in this equation as substitutes:
I = 10^(107/10) * I0 = 10^10.7 * I0

what magnitude of force, in newtons, must an 97.5-kg grouper exert to stay submerged in salt water (with density 1025 kg/m3) if its body density is 1015 kg/m3?
The force which is exerted by an object that is submerged in a fluid can be calculated using the equation of buoyant force:
Fb = ρf * V * g
where:
Fb = buoyant force
ρf = density of the fluid (1025 kg/m3 for salt water)
V = volume of the object
g = acceleration due to gravity (9.8 m/s^2)
As the density of the grouper (1015 kg/m3) is less than the density of the fluid (1025 kg/m3), the following object will experience an upward buoyant force.
So to stay submerged, the grouper must exert a force which is equal to the buoyant force in the opposite direction, that is downward.
Therefore, to find the volume of the grouper:
V = m / ρb
where:
m = 97.5 kg (mass of the grouper)
ρb = 1015 kg/m3 (density of the grouper)
Substituting the values into the equation:
V = 97.5 kg / 1015 kg/m3 = 0.096 m^3
Next, calculating the buoyant force:
Fb = ρf * V * g
= 1025 kg/m3 * 0.096 m^3 * 9.8 m/s^2
= 967.68 N
The magnitude of the force the grouper must exert to stay submerged is equal to the buoyant force:
F = 967.68 N
So, the grouper must exert a force of 967.68 N to stay submerged in salt water.

when the wave goes across the boundary from string 1 to string 2, the frequency is unchanged. what happens to the velocity? when the wave goes across the boundary from string 1 to string 2, the frequency is unchanged. what happens to the velocity? the velocity increases. the velocity stays the same. the velocity decreases.
The velocity of the sinusoidal wave decreases when it travels from string 1 to string 2 because the linear density of string 2 is different, causing the wave to slow down. Thus, Option C holds the truth.
When a sinusoidal wave travels from one string to another with a different linear density, its velocity changes due to the change in tension and mass per unit length of the string. The velocity of the wave is proportional to the square root of the tension divided by the mass per unit length.
If the linear density of string 2 is higher than that of string 1, the wave will slow down as it travels across the boundary because the increased mass per unit length will result in a decrease in velocity. Conversely, if the linear density of string 2 is lower, the velocity of the wave will increase as it travels across the boundary.

two large parallel conducting sheets are charged with equal but opposite charges. what is the electric field in the space between the sheets?
The electric field in the space between the two parallel conducting sheets is zero.
This is because the electric field is generated by the difference in charge between two points, and because the two sheets have equal and opposite charges, the electric field between them is zero.
electric field : A physical field created by electrically charged objects is known as an electric field. It has an impact on how charged items behave when they are close to the field. Other charged things are affected by the electric field by being drawn to or repelled by it. Electric charges or shifting magnetic fields can produce electric fields.
