Light shining through the less dense material.
Answer:
32 m/s
Explanation:
Frequency is the number of waves that pass a particular point in 1 second
Wavelength is the distance between 2 crests or 2 troughs
Speed = frequency x wavelength
Substituting the values
Speed = 4 Hz x 8 m
Speed = 32 m/s
Waves speed is 32 m/s
the kinetic energy always increases whether the temperature increases or decreases
the total kinetic energy of the molecules is not affected by a change in temperature
as the kinetic energy of the molecules decreases, the temperature increases
Answer: as the temperature increases, the kinetic energy of the molecules increases
Explanation: The kinetic energy of the molecules is the energy possessed by virtue of motion of the particles.
Kinetic energy of the particles is directly proportional to the temperature of the gas.
where T= temperature
R= gas constant
Thus if the temperature is increased, the molecules start moving more randomly and gain kinetic energy.
The production of the energy by the moving particle is called kinetic energy. The kinetic energydepends on the following:-
The kinetic energy of every state is different i.e the kinetic energy of the solid, liquid, and gas are different. The kinetic energy of the particles is directly proportional to the temperature of the gas.
T= temperature
R= gas constant
Thus if the temperature is increased, the molecules start moving more randomly and gain kinetic energy.
Hence, the correct option is A

The correct answer is option B, above a bowl of ice water.
Standard temperature is zero degrees Celsius (°C) or 32 degrees Fahrenheit (°F). Standard pressure is 760 mmHg or 1 atm.
Both the conditions of Standard temperature and standard pressure is basically the freezing point of pure water at sea level.
Thus the air above a bowl of ice water is at standard temperature and pressure
