Answer:
357.6 lb-ft
Explanation:
V = Volume = 8 ft³
dP = Change in pressure = (40-10) = 30 psig
Work done is given by


So, converting to ft-lb

The external work performed during the expansion is 357.6 lb-ft
Answer:
The key difference between diamagnetic, paramagnetic and ferromagnetic materials is that diamagnetic materials are not attracted to an external magnetic field, and paramagnetic materials are attracted to an external magnetic field whereas ferromagnetic materials are strongly attracted to an external magnetic field.
Answer:
The the angle between the axis of polarization of the light and the transmission axis of the analyzer is 52⁰.
Explanation:
Given;
I₀ as incident light intensity
The intensity of a linearly polarized light passing through a polarizer is given by Malus' law:
I = I₀Cos²θ
where;
I is the intensity after passing through the analyzer
θ is the the angle between the axis of polarization of the light and the transmission axis of the analyzer.
If 38% of the total intensity is transmitted, then I = 38% of I₀ = 0.38I₀
0.38I₀ = I₀Cos²θ
0.38 = Cos²θ
Cosθ = √0.38
Cosθ = 0.6164
θ = Cos⁻¹ (0.6164)
θ = 51.95° = 52⁰
Therefore, the angle between the axis of polarization of the light and the transmission axis of the analyzer to allow 38% of the total intensity to be transmitted is 52⁰.
A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it. Or survive butttttt we could never know unless we go through ourselves
Answer:
Paralympic swimming is an adaptation of the sport of swimming for athletes with disabilities. Paralympic swimmers compete at the Summer Paralympic Games and at other sports competitions throughout the world. The sport is governed by the International Paralympic Committee.
