New rock get on top of old rock to form new layers of rock
The sun. The more mass an object has, the greater gravitational pull it will have, as mass attracts other mass.
Answer:
10 seconds
Explanation:
We have the equation V = at (speed = acceleration x time)
We want to find the time, so can rearrange to T = V/a (time = speed / acceleration).
From the question, we know V is 5 and a is 0.5.
Now we can substitute that into our equation: 5/0.5 = 10.
So the time is 10 seconds.
Hope this helps! Let me know if you have any questions :)
Answer:
Force = 358.11 kN
Explanation:
Resultant force = Centripetal force.
Mass, m = 1900 kg
Velocity, v = 99 m/s
Radius, r = 52 m
Substituting
Force = 358.11 kN
-- Since the sphere is a conductor, the charge on it will move around
until it's evenly distributed on the surface of the sphere. When every
tiny smitch of charge is the same distance from the charge around it,
they won't need to move around any more.
-- At that point, the situation at the center of the sphere will be:
For every smitch of charge on the surface, causing en electric field
at the center, there is another smitch, of the same size and in exactly
the opposite direction, canceling out the field of the first one.
Every smitch of charge on the surface causes a tiny bit of electric field
at the center, and they all cancel each other.
It turn out that if the sphere is hollow, then the electric field at EVERY
point inside it is zero, not only at the center.
It's exactly the same idea as a sphere with uniform, homogeneous mass.
For that sphere, the gravity at the center is zero.
