wave speed = frequency × wavelength
This is when:
wave speed (v) is measured in metres per second (m/s)
frequency (f) is measured in Hertz (Hz)
wavelength (λ) is measured in metres (m)
7 x 15 = <u>105 m / s</u>
Answer:
Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity.
Explanation:
Answer:
Explanation:
The angular momentum of the pulsar is given by:
where
is the mass of the pulsar
is the radius
is the angular speed
Given the period of the pulsar, 
, the angular speed is given by
And so, the angular momentum is
A hydraulic arrangement consists of a water- filled U-tube that is wider on one end than on the other. Pistons are fitted in both ends.
Answer:
they stick together when they get close
