Answer:
0.0129 m
Explanation:
ΔL = FL / (EA)
where ΔL is the deflection,
F is the force,
L is the initial length,
E is Young's modulus,
and A is the cross sectional area.
F = mg = 100 kg × 9.8 m/s² = 9800 N
A = 4.0 mm² × (1 m / 1000 mm)² = 4×10⁻⁶ m²
ΔL = (9800 N) (1.0 m) / ((1.9×10¹¹ Pa) (4×10⁻⁶ m²))
ΔL = 0.0129 m
Answer:
Explanation:
Given that
Constant current I=15A
Inductance L=2.8H
a. Current changes from 15A to 0A.
∆I=0-15=-15
For a time of t=75ms=0.075s
EMF=?
EMF is given at
EMF=-L(∆I/t)
EMF=-2.8×-15/0.075
EMF=3.15V
b. Energy stored?
Energy stored is given as
E=½LI²
E=½×2.8×15²
E=315 J
c. Rate of energy? Which is power and the rate of energy is given as
Power=Energy/timetaken
Power=315/0.075
Power=4200W
P=4.2KW
Answer:
Converted to an amount of energy equal to 4 million tons times the speed of light squared. ejected into space in a solar wind.
Explanation:
The 4 million tons of mass is converted to the amount of energy that is equal to 4 million tons times the speed of light squared. This energy moves from the sun with the help of solar winds and received by the planets present in the solar system. This solar energy moves in the form of solar radiation because there is no medium for propagation so that's why we can say that the mass is converted into energy that moves in the form of radiation in discrete packets.
