Frequency can effect how tall or how long these Wavelengths are and their strength, therefore how "frequently" they will complete a wave-cycle.
Answer:
Due to the accumulation of static charges/due to static electricity
Answer: The pressure in the can is 4.0 atm
Explanation:
According to ideal gas equation:
P = pressure of gas = ?
V = Volume of gas = 0.410 L
n = number of moles = 
R = gas constant =
T =temperature =
Thus the pressure in the can is 4.0 atm
The researcher may first weight the beaker with water and then start to heat the water to a constant temperature, for example 30 °C and then start adding salt and stirring. He should add salt slowly until solid salt starts to become visible and the solution starts becoming cloudy. When this happens, he should quickly weigh the beaker. The increase in mass is the mass of salt dissolved at that temperature.
The procedure is then repeated but at an increased temperature until 5-6 temperatures have been tested.
