G is the gravitational constant, which is approximately 6.6x10^-11 Nm/s^2. It has the same value regardless of the masses of both objects or the distance between them.
Answer:
A title
Explanation:
Because this is middle school.
<u>Thermal energy</u><u> from the room-temperature water will continuously flow to the boiling water.</u>
- The second law states, in a straightforward manner, that heat cannot naturally go "uphill."
- When a pan of boiling water and a pan of ice are in touch, the hot water cools and the ice melts and warms up.
<h3>
THE FIRST LAW OF THERMODYNAMICS</h3>
- Adiabatic Process - is a procedure that is carried out without the system's heat content changing.
- Water is heated to a temperature of 1000C during the boiling process, making it an isothermal process. As steam, the excess heat leaves the system.

Answer:
The slope of a position-time graph can be calculated as:
where
is the increment in the y-variable
is the increment in the x-variable
We can verify that the slope of this graph is actually equal to the velocity. In fact:
corresponds to the change in position, so it is the displacement, 
corresponds to the change in time 
, so the time interval
Therefore the slope of the graph is equal to
which corresponds to the definition of velocity.
