Heat is something that really get hot. And transfers is when you send something to another person or another place.
Answer:
These molecules push the layer of molecules down / near, so they also start to vibrate. In this way, the oscillation is followed by one molecule next to it.
Answer:
Point 2.
Explanation:
Potential energy is simply defined as the energy stored in an object due to its position. It is can be represented mathematically by:
P.E = mgh
Where:
P.E is the potential energy.
m is the mass of the object.
g is acceleration due to gravity.
h is the height to which the object is located.
From the above equation, we can thus say that potential energy depends on the height of the object since the mass of the object is always constant i.e as the height of the object increase, the potential energy also increases and as the height of the object decrease, the potential energy also decreases.
Now, considering the diagram in the question given, we can see that point 2 is the lowest height to which the rider is located. At this point i.e point 2, the rider will have the least potential energy.
Answer:
100Ns
Explanation:
find velocity and then plug into momentum formula momentum=(velocity)(mass)
