b) the rate of heat addition into the oil.
The above have been solved for in the below workings
Explanation:
Answer:
Magnitude of velocity=10.67 m/s
Magnitude of acceleration=24.62 ft/
Explanation:
The solution of the problem is given in the attachments
Answer:
0.1 nm
Explanation
Potential deference of the electron is given as V =150 V
Mass of electron 
Let the velocity of electron = v
Charge on the electron 
plank's constant h =
According to energy conservation 

Now we know that De Broglie wavelength 
You can get hurt if u don’t use it properly.
