Answer:
5365 N
Explanation:
v = Final velocity = 23 m/s
u = Initial velocity = -14 m/s (opposite direction)
m = Mass of ball = 145 g
t = Time taken = 1 ms
Impulse is given by
Impulse is also given by
The magnitude of the average force exerted by the bat on the ball is 5365 N
The snake and rat both share the same ancestor population that had a quadrate bone, which was inherited from an ancestor population.
<h3>What is a homo-logous structure?</h3>
A homo-logous structure is a trait that may or not have the same function but has a common evolutionary origin.
A homo-logous structure can be used to trace the evolutionary relationships between species.
Conversely, an analogous structure has the same function but it does not reflect an evolutionary origin.

Answer:
Frequency
Explanation:
The property of waves that remains unchanged as it crosses the boundary of one medium to another is the frequency of the wave.
As a wave moves from one boundary to another, the wavelength and the speed of the wave changes.
The speed of the wave is product of wavelength and frequency. Also, the wavelength of the wave is function of the distance between successive crests or troughs of a wave.
The frequency of a wave is the number of waves that crosses a medium per unit of time.
A transverse wave and a longitudinal wave.
Transverse:wave particles move at medium speed in perpendicular to the direction that the waves move
Longitudinal:wave particles move at medium speed in parallel to the direction that the wave moves
