Answer:
ΔP = 986 Kpa
Explanation:
The solution is given in the pictures below
Answer: Given the evidence in the explanation, I'm pretty sure it's C. It still exists, but in a different form.
Explanation: "Some part of the energy supplied is used to change the internal energy of the system. Some part is also released into the surroundings. Generally, frictional losses are more predominant for the machines being not 100% efficient. This friction leads to the loss of energy in the form of heat, into the surroundings."
Explanation:
In the picture.
I hope that it's a clear solution.
Answer:
The value of the time constant is 558.11 sec.
Explanation:
Given that,
Pendulum length = 1 m
Initial angle = 15°
Time = 1000 s
Reduced amplitude = 2.5°
We need to calculate the value of the time constant
Using formula of damping oscillation

Where,
=amplitude
=amplitude at t = 0
Put the value into the formula





Hence, The value of the time constant is 558.11 sec.
The kitten's velocity is V=0.625 m/s
<u>Explanation:</u>
<u>Solving the problem,</u>
Given
Mass=0.8 kg
Momentum=0.5 kg.m/s
Velocity=?
We have the formula,
P=M*V
V=P/M
V=0.5 kg.m/s/0.8 kg
V=0.625 m/s
The kitten's velocity is V=0.625 m/s
