Answer:
the force acting on the car is 3600 N
Explanation:
The computation of the force acting on the car is shown below:
As we know that
Force = mass × acceleration
= 1200 kg × 3.0 ms/^2
= 3600 N
hence, the force acting on the car is 3600 N

According to pascal's law pressure transmit will be same in all direction in a closed container




If temperature T increases , speed of sound v also increases , now by , λ=v/f , as v increases , λ (wavelength) will increase . Frequency is characterised by the source of sound hence it is not affected by temperature , and as T=1/f , so time period also doesn't change.
