Answer:
Mass: the quantity of matter which a body contains, as measured by its acceleration under a given force or by the force exerted on it by a gravitational field.
Example: a person or object may be weightless on the moon because of the lack of gravity, but that same person or object maintains the same mass regardless of location. Knowledge of mass is crucial in science.
Answer:
ambulance speed is 30.38 m/s
Explanation:
given data
hear frequency = 510 Hz
pass frequency = 427 Hz
speed of sound = 343 m/s
to find out
ambulance speed
solution
we consider here ambulance speed is v
so when we hear frequency velocity equation will be
510 = 343f / ( 343 - v ) ...........................1
and when ambulance pass velocity equation will be
427 = 343f / ( 343 + v ) ...........................2
so from equation 1 and equation 2
= 510 / 427
= 510 / 427
solve it we get
v = 30.38 m/s
so ambulance speed is 30.38 m/s
