Answer:
14m/s2
Explanation:
initial velocity=2m/s
final velocity =?
time=4s
acceleration=3.0m/s
v=u+at
v=(2)+(3*4)
v=14m/s
by substituting the values in the equation we get the value 14m/s.

Answer:
You drive 60 miles in one hour if you drive at 60 miles an hour. You are traveling at one mile a minute.
Explanation:
You would travel one mile if you move at one mile an hour.
Answer:
The answer is "The frequency of the sound waves increases".
Explanation:
Its most oscillating their frequency waves, therefore higher the vibration we hear. However you see, sound frequency is determined through the oscillation of electrical signals while moving to our ears, which implies that perhaps the audio medium, which usually is air, makes a distinction between compression to spreading. It's the end of the communication as the frequency rises.
