The formula used for finding the tangential speed (speed of something that is moving in a circular path) of an orbiting object is:
V₍t₎ = ωr
V₍t₎ = tangential speed or velocity
ω = angular velocity
r = radius of the circular path
if time taken t is only given then use this formula to calculate the tangential speed:
V₍t₎ = 2πr/t, t is time taken
Answer:
The caterpillar had to move across the horizontal segments. I hope this helps :)
Explanation:
Answer:
Explanation:
From the Law of Conservation of Momentum, we can write the following equation:
Because the toy car was initially at rest, 
.
Therefore, we can plug in given values and solve for 
:
(two significant figures).
Longitudinal Waves
In a longitudinal wave, the motion of the medium is parallel to the direction of the wave . This means that the particles move left and right which in turn makes the other particles start to oscillate. Sound waves are longitudinal waves.
Another example of a longitudinal wave is a P wave or primary wave during an earthquake. P waves are also known as compressional waves, because of the pushing and pulling they do.
