Answer:
<h3>The answer is 15 N</h3>
Explanation:
The force acting on an object can be found by using the formula
<h3>Force = mass × acceleration</h3>
From the question
mass = 50 g = 0.05 kg
acceleration = 300 m/s²
We have
force = 0.05 × 300
We have the final answer as
<h3>15 N</h3>

The speed will increase four (4) times when the frequency of sound wave is increased four (4) times.
<h3>How to calculate the
frequency of a
wave.</h3>
Mathematically, the frequency of a sound wave is given by this formula:
<u>Where:</u>
- F is the frequency of a sound wave.
- V is the velocity of a sound wave.
- is the wavelength of a sound wave.
<u>Note:</u> The frequency of the sound wave is increased four (4) times.
Substituting the given parameters into the formula, we have;
Therefore, the speed will increase four (4) times when the frequency of sound wave is increased four (4) times.

As a form of potential energy I suppose, if you can think about making a cake, you have motivation to make a cake, you can make a cake. In that way, your thoughts allow for action, which equals energy.
Answer:
Yes, the magnet force will cause the motor rotate through a full rotation. So the friend who claims to have built a motor by attaching a shaft to the core of a galvanometer and removing the spring is correct.
