Answer:
By the information provided we can find the cars speed.
Explanation:
- Speed is the distance traveled by any object in certain time. As we have distance traveled by car as 30 miles.
- And time taken by car to travel 30 miles is half an hour. So speed is easily calculated as,
. - Velocity is a vector quantity so we cannot determine velocity by knowing only distance and time, we need additional information of direction to know cars velocity.
- So the speed will be,
.
Answer:
your answer is wavelength
Explanation:
the the highest service part of a weight is called the crest and the lowest part is the trough the vertical distance between the crest and the trough is the waist height the horizontal disc distance between two adjacent Crest or troughs is known as wavelengths
Speed=wavelength×frequency
speed= 0.005m × 10 Hz = 0.05m/s
