The force of gravity between the apple and the baseball is 3.335×10¯¹¹ N
The following data were obtained from the question given above:
Mass of apple (M₁) = 1 Kg
Mass of baseball (M₂) = 2 Kg
Distance apart (r) = 2 m
Gravitational constant (G) = 6.67×10¯¹¹ Nm²/Kg²
<h3>Force (F) =? </h3>
The force of gravity between them can be obtained as follow:
Therefore, the force of gravity between them is 3.335×10¯¹¹ N

If the ladder is vertical, then the work done in ascending equals his increase in potential energy.
For a man of mass (m) climbing height (h), the PE is (mgh), where g is the acceleration due to gravity.
If he does this in time t, his average power (rate of working) is:
mgh / t
= 80 * 9.81 * 6 / 12
= 392.4 W.
If the ladder is not vertical but inclined at an angle the horizontal, the power is mgh sin(a) / t.
Mass doesn't affect velocity at all; gravity affects everything the same (9.8meters/seconds^2)
Answer:
Its A
Explanation:
This region is known as the mantle, and accounts for the vast majority of the Earth's volume. Movement, or convection, in this layer is also responsible for all of Earth's volcanic and seismic activity
Answer:
-140
Explanation:
A gas loses 80joules of heat.
The gas also does 60 joules of work
Therefore the change in internal energy can be calculated as follows
= -80 + (-60)
= -80-60
= -140
Hence the change in internal energy is -140
