Answer:
(a) = 1. Thus the wave function is normalized.
(b) E, 2E₁, 4E₁
Explanation:
The detailed solving of the question is in the attach document.
Explanation:
The angle of incidence is always smaller than the angle of refraction
Answer:
19.98Joules
Explanation:
Energy possessed by the body is the kinetic energy
Kinetic Energy = 1/2mv²
m is the mass
v is the velocity
For the 4kg moving at 6m/s
kE = 1/2 * 4 * 6^2
KE = 1/2 * 4 * 36
KE = 72Joules
For the 4kg moving at 5.1m/s
kE = 1/2 * 4 * 5.1^2
KE = 1/2 * 4 *26.01
KE = 52.02Joules
Amount of Energy lost = 72 - 52.02
Amount of Energy lost = 19.98Joules
Hence the amount of Energy lost is 19.98Joules
Answer:
T = 144°C
Explanation:
From the law conservation of energy,
Heat loss = Heat gain
mc(T-50) = 2mc(50-3)
T-50 = 2(47)
T-50 = 94
T = 94+50
T = 144°C
