Explanation:
Ans 1 ) As the gravity of a planet increases, there will be increase in thickness of atmosphere around that planet. The gravitational force of the planets holds the bulks of molecules of atmosphere (as gas will need higher escape velocity).
Ans 2) Mars is the easier planets among all other planets in our solar system as it lies in habitable zone and it as a moderate gravity (where live can survive). Well, there's lot of resources too.
Thanks for asking
Answer:
physic, is natural science of motion and behavior
At time t = 0 the velocity is v1. Therefore C1 = v1 and C2 = x1. Equations (1), (2), (3), and (4) fully describe the motion of particles, or bodies experiencing rectilinear (straight-line) motion, where acceleration a is constant.
Answer:
Explanation:
Given
density of cylinder is 
Length of first cylinder is 
radius 
For cylinder 2 
and 
are the height above water
E
as object is floating so its weight must be balanced with buoyant force
For 2nd cylinder
Dividing 1 and 2 we get
That's what happens whenever anything is dropped or falls.
-- a roller coaster leaves the top of a hill
-- a pencil rolls off the desk
-- the cat jumps off the top of the refrigerator
-- the little boy slides down the slide
