Answer:
2.1 cm
Explanation:
The general equation for the graph is:
y = A cos(ωt + ∅)
A: amplitude, is the maximum and minimum value for y(t)
Pretty sure it's the last one:
"reduce the size of the input force needed to perform a task"
The correct answer is:
sixteen times
In fact, the distance between charge q and the source S is 1 unit. Instead, the distance between charge p and the source S is 4 units. The magnitude of the electrostatic force is inversely proportional to the square of the distance between the charge and the source:

where r is the distance. If we take the force between q and S as reference, we have r=1, so that

while the force between p and S is

Therefore, we see that the force exerted between q and S is 16 times the force exerted between p and S.
Answer:
4 m/s
Explanation:
Momentum is defined as:

where
m is the mass of the object
v is its velocity
For the object in this problem, we know:
p = 200 kg m/s is the momentum
m = 50 kg is the mass
Solving for the velocity, we find:
