Answer:
option d)
Explanation:
The amount of heat required to convert the 1 g of ice at 0 degree C to 1 g water at 0 degree C is called latent heta of fusion.
H = m Lf
where,, h is the heat required, m is the mass and Lf is the latent heat of fusion
1140 = m x 79.7
m = 14.3 g
Answer:
t = 17658 s = 294.3 min = 4.9 h
Explanation:
The general formula for power is:
where,
P = Power of the Motor = 50 KW = 50000 W
W = Work Done by Motor = Change in P.E of Water = mgh
g = acceleration due to gravity = 9.81 m/s²
m = mass of water = ρV
h = depth of water = 180 m
ρ = density of water = 1000 kg/m³
V = Volume of Water = 500 m³
t = time taken = ?
Therefore,
<u>t = 17658 s = 294.3 min = 4.9 h</u>
Answer:
The electromagnetic spectrum in order of increasing frequency is - radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.
The frequency of the gamma rays is >3×10
19
m.
Hence, the gamma rays has the maximum frequency in the electromagnetic spectrum.
