Answer:
because of the raindrop velocity relative of the car has a vertical and horizontal component
Explanation:
- The car moves in a <em>horizontal direction </em>relative to the ground. The raindrops fall in the <em>vertical direction</em> relative to the ground.
- Their velocity relative to the moving car has both vertical and horizontal components and this is the reason for the diagonal streaks on the side window.

-
The drops are pushed off to one side of the windshield because of air resistance.
Answer:
The sound level will be 1.870 dB louder.
Explanation:
Given that,
Power = 130 W
Power = 200 W
We need to calculate the sound level
Using formula of sound level
For one amplifier,
...(I)
For other amplifier,
...(II)
For difference in dB levels
Hence, The sound level will be 1.870 dB louder.
