Answer:
The range of wavelengths of the sound is 7692.30 m and 3846.15 m
Explanation:
A bat emits pulses of sound at a frequency between 39 kHz and 78 kHz. It is required to find the range of wavelengths of this sound.
Bat uses ultrasonic waves. It moves with the speed of light.
If f = 39 kHz,

If f = 78 kHz,

So, the range of wavelengths of the sound is 7692.30 m and 3846.15 m.
Answer:
the answer is b temperature
Temperature - The measure of the average kinetic energy of a substance
Internal Energy - Total potential and kinetic energies of the particles of a substance
Heat - Thermal energy that flows from one substance to another
Thermal Energy - Part of internal energy that can be transferred
Answer:
F=84.68 N
Required force increases
Explanation:
By the equation

By newton's second law :

When the mass increased the force increases as the equation.
F=ma
