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}

What is occurring when two waves traveling along the same medium meet and cancel each other out?
liberstina [14]

Answer:

Destructive interference

Explanation:

Destructive interference occurs when two waves traveling along the same medium meet and cancel each other out. The resultant wave has a smaller amplitude than the individual waves. In this case, the maxima of two waves are 180 degrees out of phase.

Hence, the correct option is (A) "destructive interference"
