Refraction is the change in direction of waves that occurs when waves travel from one medium to another. It is always accompanied by a wavelength and speed of change. Diffraction is the bending of waves around obstacles and openings.
Answer:
0.0142 m/s (unrounded answer is 0.01416666667)
Explanation:
distance = speed ÷ time. 4.25 ÷ 300 = 0.0142
Answer:
Explanation:
Average net force = mass × acceleration
The mass of the toy car is measured first and noted
To calculate the velocity,
Use a metre rule to mark out the distance .the car starts from rest since the velocity is associated with the distance and time after 5s.
Velocity = distance/time
With that the velocity can be found.
acceleration is defined as change in velocity per unit time.
acceleration= velocity/time
