Sound waves produced by a vibrating object are _____.

Answer: 1) Sound waves produced by a vibrating object are compressional waves. The reason being that the matter in the medium moves back and forth in the same direction that it travels. 2) Loudness is the human perception of sound wave intensity. 3) The process of detecting objects by bouncing sounds off them is called echolocation. It is also called bio sonar and animals like bats use it to detect objects near them.

I hope it helps, Regards.

if a car engine does 600,000 J of work over a 500m distance and the mass of the car is 250Kg then what is the final velocity of

drek231 [11]

Given that

Work = 600,000 J ,

distance(S) = 500 m ,

mass (m) = 250 Kg ,

Determine the velocity of car (v) = ?

We know that,

Work = Force × distance

=> Force = Work ÷ distance

= 600,000 ÷ 500

= 500 N .

Also Force F = m.a ; from Newtons II law

500 = 250 × a

a = 2 m/s.

<em>Final Velocity from the given formula </em>

V² = u² + 2.a.s

= 0 + 2 × 2 × 500

= \sqrt{2000}
