Answer:
3.125J
Explanation:
K.E.= 1/2(mass)(velocity)^2
K.E.=1/2(0.25)(5)^2=3.125
The function is electromagnets.<span />
A plane has more mass in it. Also, the engine is very strong which it makes the plane able to push through the wind. When the wind is pushing, it goes by it because of the engine.
according to conservation of momentum , total sum of momentum of the objects taking part in a collision is same before and after the collision.
Total momentum before collision = Total momentum after the collision
when a cue ball moving at velocity 1.5 m/s hits a billiard ball , transfer of momentum takes place between the balls such that total sum of momentum of cue ball and billiard ball remain same before and after the collision.
hence we say that the momentum is conserved.
The frequency of a tuning fork that takes2.50×10⁻³ s to complete one oscillation would be 400 Hz.
<h3>What is the frequency?</h3>
It can be defined as the number of cycles completed per second. It is represented in hertz and inversely proportional to the wavelength.
As given in the problem a tuning fork takes 2.50×10⁻³ s to complete one oscillation.
Frequency = 1/time period of the oscillation
Frequency of the tuning fork = 1/time period
=1/2.50×10⁻³
=400 Hz
Thus the frequency of a tuning fork comes out to be 400 Hz.
