Force on left crate, right crate and truck we need to draw here
First we will write the equation for left crate


Now similarly for right crate

now for truck

Now we know that F = 200 N

now add all three equation



now we will find all tension using this value of acceleration



Answer: energy
Explanation: A wave is a disturbance that transfers energy as it travels through medium.
Answer:
the frequency heard by the observer is equal to 2677 Hz
Explanation:
given,
velocity of the observer = 17 m/s
speed of the sound = 343 m/s
velocity of the source = 0 m/s
frequency emitted from the source = 2550 Hz

velocity of observer is negative as it is approaching the source. f = 2676.38 Hz ≈ 2677 Hz
hence, the frequency heard by the observer is equal to 2677 Hz
Answer:
acceleration
Explanation:
acceleration =velocity final-velocity initial /time
40V because it will provide the same amount of power.
