Answer:
12552 J or 3000 calories
Explanation:
Q = m × c × ∆T
Where;
Q = amount of heat energy (J)
m = mass of water (g)
c = specific heat capacity (4.184 J/g°C)
∆T = change in temperature
For 50mL of water, there are 50g, hence, m = 50g, c = 4.184 J/g°C, initial temperature = 0°C, final temperature = 60°C.
Q = m × c × ∆T
Q = 50 × 4.184 × (60 - 0)
Q = 209.2 × 60
Q = 12552 J
Hence, the amount of heat energy used to heat the water is 12552 J or 3000 calories

Answer:
50s .
Explanation:
Here the power of the microwave is 0.2kW . And as we know that ,
- Rate of doing work is called power .
So from the definition , we have ;
- Here the work done is equal to the energy consumed by the microwave i.e. 10000 J .So we can write it as ,
Cross multiply ,
Simplify ,
<h3>Hence the time taken is 50s .</h3>
Answer: 
Explanation:
The Compton Shift 
in wavelength when photons are scattered is given by the following equation:
(1)
Where:
is the wavelength of the scattered photon
is the wavelength of the incident photon
is a constant whose value is given by 
, being 
the Planck constant, 
the mass of the electron and 
the speed of light in vacuum.
the angle between incident phhoton and the scatered photon.
(2)
(3) This is the shift in wavelength
