PWC stands for personal watercraft, and it is a small powerboat. The main components of a PWC are the hull (body of the boat), deck (surface where people walk/stand), throttle (controls speed), steering nozzle and water intake.
Answer:
630cm/s
Explanation:
In simple harmonic motion, the tangential velocity is expressed mathematically as v = ὦr
ὦ is the angular velocity = 2πf
r is the radius of the disk
f is the frequency
Given the radius of disk = 10cm
frequency = 10Hz
v = 2πfr
v = 2π×10×10
v = 200π
v = 628.32 cm/s
The tangential velocity = 630cm/s ( to 2 significant figures)
It would be a really bad idea to eat the snow because you obviously are trying to stay warm right? Well, the best thing to do is melt the snow. However, the process of melting the snow would have a few complications as well. But yes, the latter idea (drinking the snow) is a better idea (not the best).
Explanation:
It is known that relation between kinetic energy and temperature is as follows.
Hence, kinetic energy is directly proportional to temperature.
Thermal energy is defined as the energy present within the molecules of an object due to the motion of particles. Basically, thermal energy is internal energy of an object.
Thus, we can conclude that:
- Temperature and kinetic energy are directly proportional.
- Heat is a measure of thermal energy.
- Temperature is proportional to the total kinetic energy.
