Answer:
5m/s/s
Explanation:
The units for velocity is m/s.
The units for acceleration is m/s/s
So, Determine the change in velocity and divide it by the time that change took place.
(30m/s - 10m/s)/4s = 20m/s/(4s) = 5m/s/s
well the formula to find speed is distance divided by time and you already have the time so all you need to know to find the average speed of the car is the total distance around the racetrake.
Explanation:
There is no any direct relationship between the frequency of a sound relative the intensity of the sound.
Frequency is a perception of pitch of the sound whereas intensity determines the loudness of the sound. Intensity is proportional to amplitude of the sound.
So, it would be hard to determine how much more intense is a 6000 Hz tone than a 80 Hz tone.
