Some of the early planetesimals that formed the solar system still survive in the asteroid and Kuiper belts.
Asteroids are the rocky leftover planetesimals of the internal solar device. Planetesimals shape in protoplanetary disks, many develop into big planets, whilst others do no longer get that possibility. in the solar gadget, remnant planetesimals and minor planets inhabit the asteroid belt, Kuiper belt, Oort cloud, and different solid niches.
After the planets had been shaped, their gravity hurled most of the last planetesimals into the solar or into remote orbits around it. Phobos and Deimos are believed to be planetesimals that were captured through Mars gravity and became satellites. many of Jupiter's moons are believed to be planetesimals as well. Planetesimals are very precious to scientists because they are able to offer information approximately the introduction of our solar gadget
A planetesimal is small our bodies from which a planet originated in the early stages of formation of the solar system. Protoplanets are while planetesimals join together thru collisions and via the force of gravity to form larger our bodies

Answer:
1.52 m
Explanation:
We are given that
Maximum force=F=679 N
Mass of rock ,m=385 kg
Distance,d=0.233 m
We have to find the minimum total length L of the rod required to move the rock.
Torque on rock=
Where
Torque on man=
Hence, the minimum total length of rod=1.52 m
Answer:
Explanation:
We have acceleration given by
Velocity at t = 0
Velocity is given by
at t = 0
The equation will be
