Answer:
a) 0.1832 A
b) 11.91 Volts
c) 2.18 Watt , 0.0168 Watt
Explanation:
(a)
R = external resistor connected to the terminals of the battery = 65 Ω
E = Emf of the battery = 12.0 Volts
r = internal resistance of the battery = 0.5 Ω
i = current flowing in the circuit
Using ohm's law
E = i (R + r)
12 = i (65 + 0.5)
i = 0.1832 A
(b)
Terminal voltage is given as
= i R
= (0.1832) (65)
= 11.91 Volts
(c)
Power dissipated in the resister R is given as
= i²R
= (0.1832)²(65)
= 2.18 Watt
Power dissipated in the internal resistance is given as
= i²r
= (0.1832)²(0.5)
= 0.0168 Watt
The power of a machine is the work/time ratio for that particular machine
Its the rate of doing work.

Answer:
The frequency of this photon is 
(D) is correct option.
Explanation:
Given that,
Excited states,
We need to calculate the wavelength
Using formula for energy
We need to calculate the frequency
Using formula of frequency
Where, E =energy
Hence, The frequency of this photon is
Velocity is a vector quantity. Therefore, while specifying the magnitude of velocity, we also need to mention in what direction its vector *point* in space.
Here, velocity of plane is "500 m/s towards west"
