<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>
Answer:
Hey guess what there's no question genius
Explanation:
First find Acceleration
- Initial velocity=u=0m/s
- Final velocity=v=42m/s
- Time=t=2s
- Distance=s
- Acceleration=a
Using second equation of kinematics
