Answer:
Explanation:
Increases. The force of gravity is distance dependent. Therefore, a smaller 'r' value will result in a larger force. Net force is proportional to the acceleration, so the planet will increase its speed.
Answer:
a. ρ
b.
Explanation:
a. To find the density of magnetic field given use the gauss law and the equation:
, , Ω, , ,
ρ
ρ
ρ
ρ
b. The electric field can be find using the equation:
The amount of gravitational potential energy acquired by the rock is equal to:
where
m is the mass of the rock
g is the gravitational acceleration
is the increase in height of the rock
Substituting the data of the problem, we find
So, Natalie gave 220.7 J of energy to the rock.
Answer:
Explanation:
sin^2 60° = ( \|3 / 2 ) ^2 = 3 / 4.
If a coastline has a very unusual shape it's normally caused by either a flood or dam.
