A proton is moving at 105 m/s at a point where the potential is 10 V. Later, it is at a place where the potential is 5 V. What i
1 answer:
Answer:
The speed is
Explanation:
Given that,
Speed of proton
Final potential = 10 v
Initial potential = 5 V
We need to calculate the speed
Using formula of energy
The speed of the particle is directly proportional to the potential.
Put the value into the formula
....(I)
For 5 V,
.....(II)
From equation (I) and (II)
Hence, The speed is

For the cat to stay in place on the merry go round without sliding the magnitude of maximum static friction must be equal to magnitude of centripetal force
Where the r is the radius of merry-go-round and v is the tangential speed
but
So we have
Substitute the given values
So
Explanation:
Usually when we think of waves, we think of transverse waves. These are waves where points move up and down perpendicular to the motion of the wave. Examples include water waves, whipping a rope, or even doing the "wave" in a crowd. You can think of these as "two dimensional" waves.
Longitudinal waves are waves where points move left or right, parallel to the motion of the wave. In other words, there is compression and expansion of the medium. Examples include sound waves, or pulses in a slinky.
