When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. ... When heat leaves all substances, the molecules vibrate slower.
I looked it up so this is googles answer
Answer:
Explanation:
Given
initial velocity 
Distance traveled before stopping 
using equation of
where v=final velocity
u=initial Velocity
a=acceleration
s=displacement
v=0 as car stops after travelling 
negative sign indicates it is deceleration
Answer:
GREATER than 1 g/cm. 3, it will SINK in water. LESS than 1 g/cm3, it will FLOAT in water. If an object's density is: Density of Object > Density of Liquid.
Explanation:
Answer:
g, downward
Explanation:
It is given that, a baseball is thrown straight upward. The force acting on the stone is force of gravity. It is moving under the action of gravity. We know that the force of gravity always acts in a downward direction.
At the highest point, the velocity of the stone will be equal to 0. It will move will constant acceleration equal to g and it always acts in downward direction.
Hence, the correct option is (e) "downward direction".
