Answer:
Thermal energy
Explanation:
I believe it is because the movement of particles has a connection with the temperature. Example: Since gas particles move very fast, it must be hot and freshly occurred through heating process.
The correct answer to the question is unitless i.e the IMA of a mechanical system has no unit.
EXPLANATION:
The IMA of a mechanical system stands for ideal mechanical advantage. It can be defined as the number of times the input or effort force provided to the mechanical system is multiplied under ideal conditions. The ideal conditions means that the system is free from friction, air resistance etc.
Let us consider
is the distance over which the input force is applied.
Let
is the distance over which the output force is applied.
The ideal mechanical advantage of the system is calculated as -
IMA =
.
Both
are measured in distance unit.
Hence, IMA is a unitless physical quantity.
Answer: Infrasound is the span of low-frequency sounds below 20 Hz that fall below the hearing range of humans. While these sounds escape our ears, scientific instruments can detect them—and tell us some interesting things about the planet.
Explanation:
Answer:

Explanation:
We are given that
The wavelength of sound wave=
1 cm/s=
Speed of sound wave,v=
We have to find the period of the wave.
We know that
Frequency=
Using the formula
Frequency =
Hz
Time period=
Using identity:
Hence, the time period of the wave=
