Often we think that heat and temperature are the same thing. ... Heat and temperature are related to each other, but are different concepts. Heat is the total energy of molecular motion in a substance while temperature is a measure of the average energy of molecular motion in a substance.
Answer:
1863 J
Explanation:
F = Force moving the object
f = Frictional force = 230 N
The forces in the horizontal direction have the force balance
So, the force by which the object is being pushed is
s = The displacement of the object = 8.1 m
Work done is given by
The work done by the mover is 1863 J.
Answer:
deep in the earth's crust
Explanation:
Answer:0.3
Explanation:
Given
velocity of car=15 m/s
truck brought to halt in a distance of 38 m
We know
Final velocity (v)=0
(deceleration)
Therefore minimum coefficient of friction \mu will be
A microwave uses heat waves that keeps in side the machine to heat up the cup of water
Hope this helps :)
