An electromagnetic radio wave is received by a transmitter before it is converted to a sound wave. The radio wave has a waveleng
lakkis [162]

Answer: The velocity is the wave traveling at before the transmitter converts it to a sound wave is 2.99\times 10^8 m/s

Explanation:

Wavelength of the  electromagnetic wave = 23,076 m

Frequency of the wave = 13,000 Hertz

\text{Time period}=\frac{1}{Frequency}

Velocity=\frac{displacement}{Time}=\frac{\lambda}{\text{Time period}}=\lambda \times Frequency=23,076\times 13,000 Hertz=2.99\times 10^8 m/s

The velocity is the wave traveling at before the transmitter converts it to a sound wave is 2.99\times 10^8 m/s

A bottle of water at a room temperature of 21.0 C is placed into a refrigerator
fredd [130]

Answer:

B. in both directions until the temperature is equal in the water and the air

Explanation:

When a warm body is in contact with a cool body , there is exchange of heat energy in both sides until there is attainment of equilibrium temperature . At this temperature both the body attains equal temperature . Initially rate of heat radiated by warm body is more than that from cool body , but after attainment of equilibrium , the rate becomes equal to each other . This is called dynamic equilibrium .

Hence option B is correct .
