Given: Work W = 3,500 J; Force f = 250 N; Weight w = 765 N
Required: Distance d = ?
Formula: Work = force x distance or W = f x d
Distance d = W/f
d = 3,500 J/250 N
d = 14 m
Answer:
A. 2.76 × 10-1 meters
Explanation:
The electrostatic force between two charges is given by:
where
k is the Coulomb's constant
q1 and q2 are the two charges
r is the distance between the charges
In this problem, we know:
So we can re-arrange the equation to find the distance between the two charges:
Which corresponds to option A, 2.76 × 10-1 meters.
It would make Jane the most powerful because she got it done faster than Dylan did.
Answer:
3.2 kg
Explanation:
x = Stretched length
k = Spring constant
c = Damping constant
Force
For critical damping
The mass that would produce critical damping is 3.2 kg
