Answer:
Friction
Explanation:
Friction can be simply defined as the force that creates resistance to any motion of a particular object that moves relative to another object. It occurs because of the electromagnetic force of attraction that is generated by the charged particles located between the two distinct contacting surfaces. It is a non-fundamental force.
This type of force is mainly responsible for the resisting of sliding and/or rolling of an object over the other one.
Answer:
All electrons are negative(-) charged
Your mass wouldn’t change, but your weight would. Weight depends on the force of gravity however mass does not. When you land on the moon, your mass is the same as it was on the earth but weight will drop
The frequency of the signal is = 2.5 Hz
<h3>Calculation of frequency</h3>
The wavelength of the sonar device = 5.9 m
The velocity of the sound = 15 m/s
The frequency = ?
But the formula for the velocity of sound wave = frequency × wavelength
Male frequency the subject of formula,
f = v/ wavelength
f = 15/5.9
f = 2.5Hz
Therefore, the frequency of the signal is = 2.5Hz
