Answer:
Calorimetry
Explanation:
In the calorimetry experiments, mix a known amount of a high temperature material, about 100 ° C, with an equivalent amount of water at room temperature. In a device thermally isolated from the environment, and the initial and final temperatures of liquid and solid are analyzed and energy conservation relationships, the specific heat of the unknown material can be found.
Answer:

Explanation:
From the question we are told that
The number of turns is 
The radius is 
The position from the center consider is x = 3.45 cm = 0.0345 m
The induced emf is 
Generally according to Gauss law

=> 
Where A is the cross-sectional area of the solenoid which is mathematically represented as

=> 
=>
ggl;
Here
is the permeability of free space with value

=> 
=> 
M/s, km/h, and mph are all used to measure these quantities
<u>Solu</u><u>tion</u><u> </u><u>:</u><u>-</u>
Given that ,
- Initial Velocity of car = 44km / hr.
- Final Velocity of car = 0km / hr.
- Acceleration = -5km/hr².
To Find :
- Time taken to stop the car .
So , here use first equⁿ of motion which is ,

where ,
- v is final Velocity.
- u is Initial velocity.
- a is acceleration.
- t is time taken.
Now , substituting the respective values ,
