Force M2 exerts on tension T
T = M2 g
T = M1 g sin theta - M1 g u cos theta
Note that M1 g is exerted down the plane while the frictional force opposes this motion and will be directed in the opposite direction of M1 g
M2 g = M1 g sin theta - u M1 g cos theta
1 = 2 sin 36 - u 2 cos 36
.5 = sin 36 - u cos 36
u = (sin 36 - .5) / cos 36 = .108
Any friction less that this will result in sliding
Answer: 168.75 N
Explanation:
first, let's convert microcoulombs to coulombs
q1 = 1e-4 C
q2 = 3e-5 C
r = 0.4 m
then use the equation Fe =
plug in values --> F = (9e9*1e-4*3e-5)/(0.4)^2
F = 168.75 N
Constructive interference is the addition of wave energy as waves interact, producing larger waves and destructive interference is the subtraction of wave energy as waves interact, producing smaller waves.
To find the answer, we need to know about the interference of waves.
<h3>What's the interference of waves?</h3>
- Interference of waves is the result of superposition of waves (transverse or longitudinal) at a certain place.
- Interference is of two types
- Constructive interference
- Constructive interferenceDestructive interference
<h3>How are the constructive and destructive interference formed?</h3>
- When two waves are superimposed within the phase, then constructive interference pattern is formed.
- When two waves are superimposed with out of phase, destructive interference pattern is found.
Thus, we can conclude that the constructive interference is the addition of wave energy and destructive interference is the subtraction of wave energy.

Answer:
The answer is below
Explanation:
a) The change in energy is the difference between the final energy and the initial energy.
ΔE (energy change) = Ef (final energy) - Ei (initial energy)
The negative sign shows that energy is lost to the environment. Hence 0.334 J is lost to the environment.
b) According to the law of conservation of energy, energy cannot be created or destroyed but transformed from one form to another.
The oscillating object loses energy due to wind resistance, friction between the spring and the object. Given that the air is frictionless, hence the energy loss is due to friction which is converted to heat.
