A sound wave is a wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.
Answer:
Explanation:
Given that:
- magnetic field intensity,
- kinetic energy of electron,
- we have mass of electron,
<em>Now, form the mathematical expression of Kinetic Energy:</em>
<u>from the relation of magnetic and centripetal forces we have the radius as:</u>
42.9°
Explanation:
Let's assume that the x-axis is aligned with the incline and the positive direction is up the incline. We can then apply Newton's 2nd law as follows:
Note that the net force is zero because the block is moving with a constant speed when the angle of the incline is set at Solving for the angle, we get
or
Answer:
if we ever ride a airplane we dont mess up its signals and crash ,and its easier to ignore calls and texts
Explanation:
The answer is C.
The Kinetic energy which was exerted and experience pulling the string of a bow is kept as a potential energy at the end of the arrow in contact with the string. Once release from aim at stationary position the potential energy is again transformed.
