Answer:
Explanation:
Given
Velocity of bat
Frequency of sound
velocity of sound
using Doppler Effect apparent frequency is given by
where
apparent frequency
v=velocity of sound in the given media
velocity of source
velocity of observer
here velocity of source is zero
as source is travelling towards source thus
Answer:
4 m/s
Explanation:

Answer:
The magintude of the acceleration for both objects is
Explanation:
Drawing a free body diagram on the two boxes we can analyze the system more easily.
we can take the acceleration going up as positive for reference purposes.
for mA let's suppose that is ascending so:
and for mB (descending):
because the two boxes has the same acceleration because they are attached together:
So the magintude of the acceleration for both objects is
Explanation:
Time = Distance/Speed
= 96km / (30km/h)
= 3.2h. (Or 3 hours and 12 minutes)
