Speed is the distance traveled
time
but velocity is the change in distance
time
Answer:
Explanation:
on earth, objects in free fall accelerate downward at approximately 10 m/s²
any small initial velocity is irrelevant.
Answer:
d. 
Explanation:
= Radius of the circular path
= Time period of motion
= Angular speed of the motion
Angular speed of the motion is given as

The toy is moving in a circle and hence centripetal acceleration acts on it which can be given as

hence the correct choice is
d. 
that statement is true
a Third class lever applied when the effort place between the load and the fulcrum.
For example, in a forearm serve
Fulcrum : The elbow
Effort : The effort that putted by the biceps muscle
Load : The arm
Answer : [tex]v = 59.02\ km/s[/tex]
Explanation : given that,
Arm length = 8.50 meters
Wavelength = 658 nm
Number of fringe = 1
We know that,
Formula of the speed is

Now, put the values



Hence, this is the required solution.
