The energy of one massive object has in relation with another massive object due to gravity is called gravity
70 mph
= 70 * 1600 m/h
= <span>112000 m/h
-> 112000 m/h
= 112000 /3600 m/s
= 31.111... m/s
= <u>31 m/s (2s.f)</u></span>
That statement may be considered true. 'Specific gravity' is the ratio of
the density of a substance to the density of a reference substance. The
reference substance is nearly always water, and the ratio of the density
of water to the density of water is obviously ' 1'. So there you are.
-- Charges with the same sign repel each other.
-- Charges with different signs attract each other.
-- This is called the "electrostatic force".
-- There's another set of forces called "magnetic forces", but
-- there's no such thing as "electromagnetic force".
Answer:
absorbs heat and its kinetic energy increases.
Explanation:
As we know that heat is defined as the change in the temperature as there is increase in the temperature change then the heat will increase or decrease with respect to increase or decrease in temperature change.
In the given, question temperature is changing from 20° to 50° which means there is increase in the temperature which results in the absorption of heat. And increase temperature will increase the average speed of the molecules which results in increase in kinetic energy.
