Answer:
T = 0.96 seconds
Explanation:
Given that,
The speed of wave, v = 2.6 m/s
The distance between wave crests, 
We need to find the period of the wave motion. Let T be the period. So,
So, the period of the wave motion is equal to 0.96 seconds.
Answer:
• riding on a Ferris wheel whose entrance and exit are the same
• walking around the block, starting from and ending at the same house
• running exactly one lap around a racetrack
Explanation:
Displacement simply means the.change in position of an object. In a situation whereby the initial and final position are thesame, the displacement will be zero.
The statements that describe a situation with a displacement of zero include:
• riding on a Ferris wheel whose entrance and exit are the same
• walking around the block, starting from and ending at the same house
• running exactly one lap around a racetrack
The statement which best explains why when you trip, your foot stops, but your body continues to move forward is: A. An unbalanced force stops your foot but does not act on the rest of your body.
A force can be defined as a push or pull of an object or a physical body, which typically results in a change of motion due to the interaction of the object with another.
In Physics, there are two (2) main types of force and these are:
An unbalanced force occurs when two or more forces acting on an object or a physical body are not equal in magnitude and as such, it typically results in a change of motion.
In conclusion, when you trip, your foot stops, but your body continues to move forward because an unbalanced force stops your foot but doesn't act on the other part of your body.

(a) 6.04 rev/s
The speed of the ball is given by:
where
is the angular speed
r is the distance of the ball from the centre of the circle
In situation 1), we have
r = 0.600 m
So the speed of the ball is
In situation 2), we have
r = 0.900 m
So the speed of the ball is
So, the ball has greater speed when rotating at 6.04 rev/s.
(b) 
The centripetal acceleration of the ball is given by
where
v is the speed
r is the distance of the ball from the centre of the trajectory
For situation 1),
v = 30.6 m/s
r = 0.600 m
So the centripetal acceleration is
(c) 
For situation 2 we have
v = 34.1 m/s
r = 0.900 m
So the centripetal acceleration is
