When the pedaling cyclist uses a generator (dynamo) to light his bicycle lamp, the energy change is from mechanical to electrical.
<h3>Law of conservation of energy</h3>
The law of conservation of energy states that energy can neither be created nor destroyed but can be converted from one form to another.
Thus, we can conclude the following as it relates to energy changes;
- When the pedaling cyclist uses a generator (dynamo) to light his bicycle lamp, the energy change is from mechanical to electrical.

Answer:
ANGLE is 35.3 degree celcius
Explanation:
Given data:
mass m and 3m
initial speed Vi
particle with mass m is moving toward left while particle with mass 3m is moving toward right
By using conservation of momentum :
conservation of energy :
After collision, particle with mass m moves at right angles, thus by considering conservation of momentum in x & y direction,
x direction : 
y direction : 
subsitute these value in energy conservation
35.3 degree from x-axis
Work = force * distance
force = 100 N
Distance = 5m
work =100 N* 5m
=500 J
Answer:
I thinck it would be 48.0
