Multiply 5 newton by each height. 1st is 5 joules, 2nd is 7.5, while 3rd is 10 joules.
<em>The sensitivity of a mercury thermometer can be increased by using a smaller mercury bulb, thinner wall and smaller bore. A smaller bulb contains less mercury and hence absorbs heat in shorter time. As a result it can response faster to temperature change.</em>
Angle of incidence is the angle when the light strikes an object while angle of reflection is the angle produced when the light strikes off/reflects from the object.
The relation between these two is that both the angles are equal.
The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.
Hope this helps!
Answer:
The maximum height the child can jump on the stick
h=0.459m
Explanation:
Energy conservation
Energy kinetic = Work
The energy the child do get the height jump is proportional at the distance and the consta can be compressed so:
