Answer:

Accretion

Explanation:

Accretion is the process by which there is an accumulation of particles into a bigger object by attracting more mass by gravitational force into an accretion disk. This is one of the first steps in the formation of our solar system. There was a collapse of a gas cloud which resulted in most of the mass collecting in the center leading to the formation of the sun and the rest spread out forming the planets.

A 20-pound object is dropped from a 50-foot bridge onto the ground below it. A 50-pound object is dropped from a 100-foot cliff
Anvisha [2.4K]

Answer:

here 20 lb object will hit the ground first

Explanation:

Acceleration of the object while it is dropped in air is given as

F = mg

a = \frac{F}{m}

a = g

so acceleration of the object is independent of the mass of the object

now time to reach the ground is given as

h = \frac{1}{2}gt^2

t = \sqrt{\frac{2h}{g}}

for 20 pound object

t_1 = \sqrt{\frac{2(50)}{32}}

t_1 = 1.77 s

for 50 pound object

t_2 = \sqrt{\frac{2(100)}{32}}

t_2 = 2.5 s
