Law Incorporation [45]3 years ago
6 0

Explanation:

It is given that,

Speed of a wave, v = 251 m/s

Wavelength of the wave, λ = 5.1 cm = 0.051 m

(1) The frequency of the wave is given by :

\nu=\dfrac{v}{\lambda}

\nu=\dfrac{251\ m/s}{0.051\ m}

\nu=4921.56\ Hz

(2) Angular frequency of the wave is given by :

\omega=2\pi\nu

\omega=2\pi\times 4921.56\ Hz

\omega=30923.07\ rad/s

(3) The period of oscillation is given by T as :

T=\dfrac{1}{\nu}

T=\dfrac{1}{4921.56}

T = 0.000203 seconds

or

T = 0.203 milliseconds

Hence, this is the required solution.

A 1200 kg car traveling at 60 mph quickly brakes to a halt. The kinetic energy of the car is converted to thermal energy of the
ololo11 [35]

Answer:

 ΔT = 59.9 ° C

Explanation:

For this exercise the brake energy is totally converted into heat

Let's calculate the vehicle energy

       K = ½ m v²

Let's reduce the units to the SI system

       v = 30 mph (1609.34 m / mile) (1h / 3600s) = 13.41 m / s

      Em = K = ½ 1200 13.41²

      K = 1.079 105 J

All this energy is transformed into heat

     Em = Q

The expression for heat is

     Q = m  c_{e} ΔT

     ΔT = Q / m c_{e}

The specific heat of iron is c_{e} = 450 J / Kg ºC

     ΔT = 1,079 105 / (4.0 450)

     ΔT = 59.9 ° C
