Answer:
The direction of these oscillations is the difference between longitudinal or transverse waves. In longitudinal waves, the vibrations are parallel to the direction of wave travel. In transverse waves, the vibrations are at right angles to the direction of wave travel.
Explanation:
The waves that contains the oscillations parallel to their direction of motion should be considered as the sound waves from stereo speaker.
What are sound waves?A sound wave is the wave that shows the disturbance patterns that should be lead by the movement of the energy that should be travelled via the medium like air, water, since it should be propagated away from the sound source.
Therefore, The waves that contains the oscillations parallel to their direction of motion should be considered as the sound waves from stereo speaker.

Answer:
Coal is fossil fuel extracted from earth and since it takes a long time to replenish, it is called a non renewable source of energy
Explanation:
Coal is formed from the fossil fuel that lie deep beneath the earth crust . These fossil fuels are dead remains of living organism that burried beneath the earth crust million of years ago.
Coal is non renewable because if once it gets depleted it will take a very very long time to replenish.

The musical tone a piano has a frequency of 346HZ and a wavelength of 1.3 M what is the speed of the sound
Answer:
v= 449.8 m/s
Explanation:
Given data
Frequency= 346Hz
Wave length= 1.4m
The expression below is used to find the speed

substitute
[tex]v= 346*1.3\\\\v= 449.8 m/s[/tex]
Hence the speed is v= 449.8 m/s
The specific heat capacity of copper is 390 J/Kg AC. What does this
mean?
Answer:
It means that 400 J of heat is the required amount to raise or lower thh temperature of a 1kg piece of copper
Explanation:
390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C
From the given information,
The specific heat capacity of copper is 390 J/Kg °C. To determine what this means, we will define the term specific heat capacity.
The specific heat capacity of a substance is the amount of energy required to raise the temperature of 1 kg of the substance by 1 °C.
Therefore, 390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C.
Hence, 390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C.
