☄ <u>Universal</u><u> </u><u>Gravitational</u><u> </u><u>Constant</u><u>(</u><u>G</u><u>)</u>
Gravitational constant is a constant of proportionality when F(Gravitational force) is proportional to product of masses and inversely proportional to the distance between them.
- It can be defined as:- Universal gravitational constant is the magnitude of the force between a pair of 1 kg masses that are kept 1 metre apart.
- The SI unit of G is N m²/kg² and the CGS unit of G is Dyne cm² / g².

Answer:
Explanation:
As it mostly occurs on a surface where an ecosystem has previously existed. Primary succession only occurs on a surface where no ecosystem existed ever before!
Answer:
76 seconds
Explanation:
Using the formula t=vf-vo/a, where t=time, vf= final velocity, v0= initial velocity, and a= acceleration, we can solve for your problem.
Plug in known variables...
t=200-10/a
we can solve for a by using the formula F=ma where f=force, m= mass, and a=acceleration and rearranging it to solve for a.
a=F/m
Plug in known variables...
a=250N/100kg
a=2.5m/s^2
Plug in our newly found acceleration of 2.5 m/s^2 into our first equation and solve....
t=190/2.5
t=76 seconds
