The mass of the car is 1633 kg.

<u>Explanation:</u>

Kinetic energy is the energy attained by the object when it is in motion. So the kinetic energy exhibited by any object is directly proportional to the mass of the object as well as the square of velocity of the object.

Thus as here the kinetic energy is given as 4.32 \times 10^{5} J and speed or velocity is given a 23 m/s, the mass (m) of the object can be found as

          \text {Kinetic Energy}=\frac{1}{2} \times \text { m } \times \text { speed }^{2}

         4.32 \times 10^{5}=\frac{1}{2} \times m \times 23 \times 23

Thus,

          \text {m}=\frac{4.32 \times 10^{5} \times 2}{23 \times 23} = 1633 \mathrm{kg}

The density of water is 10*3 kg/m*3. the water pressure on a submarine is 2.0 x 10*7 N/m*2. The depth of the submarine below the
Marat540 [252]

Answer:

2000metres

Explanation:

Pressure= density x height x gravity

Gravity is always a constant = 10N/kg

so height= Pressure/( density x gravity)

h= 20000000/(1000 x10)

h= 2000 metres

What do you mean by reflection of sound​
Bogdan [553]

Answer:

Reflection of sound waves also leads to echoes. Echoes are different than reverberations. Echoes occur when a reflected sound wave reaches the ear more than 0.1 seconds after the original sound wave was heard. ... Reflection of sound waves off of curved surfaces leads to a more interesting phenomenon.
