It’s either C or D. let me know but I would do C!
Answer:
The correct statements are A and E.
Explanation:
This statements will be explained according to the Newton's third law of motion. It states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction (law of action and reaction).
A. You are experiencing a larger acceleration than your friend, but in the opposite direction. True. The forces are equal, but the mass of each individual is different, so the acceleration has to be different too. In this case, the smaller mass (you) has the large acceleration.
B. You are experiencing the same acceleration as your friend, but in the opposite direction. False. The forces are equal but the accelerations are different.
C. You are experiencing a smaller acceleration than your friend, but in the opposite direction. False. You are experiencing a larger acceleration due to the smaller mass.
D. You are experiencing a smaller force than your friend, but in the opposite direction. False. The forces are equal for both masses.
E. You are experiencing the same amount of force as your friend, but in the opposite direction. True.This is what the law states.
F. You are experiencing a larger force than your friend, but in the opposite direction. False. The forces are equal.
We are given information:
m = 0.0450 kg
Δv = 25.2 m/s
Δt = 1.95 ms = 0.00195s
To find force we use formula:
F = m * a
a is acceleration. To find it we use formula:
a = Δv / Δt
a = 25.2 / 0.00195
a = 12923.1 m/s^2
Now we can find force:
F = 0.0450 * 12923.1
F = 581.5 N
To check the effect of the ball's weight on this movement we need to calculate it and then compare it to this force.
W = m * g
W = 0.0450 * 9.81
W = 0.44145 N
We can see that weight is much smaller than the applied force so it's influence in negligible.
Answer:
The Coulomb’s Law is as follows
According to this law, the force between two charged objects can be calculated using the distance between the objects. If the objects are large, then it is not possible to determine the distance, r, between that object and the other object. Because, the edge of the object contain charges as well as the center of the object.
In that case, you need to separate the object into infinitesimal points, apply the formula to those points, then integrate over the large object to find the force between objects.
