The two groups of planets based on their composition are the terrestrial planets, and the jovian planets. The terrestrial planets are small, and their composition is different than that of the jovian planets. The terrestrial planets have a solid iron inner core, liquid iron outer core, silicate mantle, and silicate crust. The jovian planets are also called gas giants because they are much larger and are gassy, not hard as the terrestrial planets. These planets have a silicate inner core, ice outer core, liquid metallic hydrogen layer, liquid hydrogen layer, and on the top gaseous hydrogen.

A homeowner is trying to move a stubborn rock from his yard. By using a a metal rod as a lever arm and a fulcrum (or pivot point
Nonamiya [84]

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=T_1=mgd=385\times 9.8\times 0.233=879.11 N

Where g=9.8m/s^2

Torque on man=T_2=Force\times distance=(L-d)\times 679=(L-0.233)\times 679

T_1=T_2

(L-0.233)\times 679=879.11

L-0.233=\frac{879.11}{679}=1.29

L=1.29+0.233=1.523\approx 1.52 m

Hence, the minimum total  length of rod=1.52 m
