The answer is A.
A positive charge’s electric field pushes out.
Hope this helps! -Avenging
A is 588N.
b) When she reaches her terminal speed, 10 seconds into the dive, she is no longer accelerating, so the net force on her is zero.
Think of it this way: If the net force were not zero she would continue to accelerate.
c) She is no longer accelerating.
Her acceleration is zero.
Time = 13.5 / 2.5 = 5.4 seconds
Answer:
9.60 m/s
Explanation:
The escape speed of an object from the surface of a planet/asteroid is given by:

where
G is the gravitational constant
M is the mass of the planet/asteroid
R is the radius of the planet/asteroid
In this problem we have
is the density of the asteroid
is the volume
So the mass of the asteroid is

The asteroid is approximately spherical, so its volume can be written as

where R is the radius. Solving for R,
![R=\sqrt[3]{\frac{3V}{4\pi}}=\sqrt[3]{\frac{3(3.09\cdot 10^{12} m^3)}{4\pi}}=9036 m](https://tex.z-dn.net/?f=R%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B3V%7D%7B4%5Cpi%7D%7D%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B3%283.09%5Ccdot%2010%5E%7B12%7D%20m%5E3%29%7D%7B4%5Cpi%7D%7D%3D9036%20m)
Substituting M and R inside the formula of the escape speed, we find:
