How are electromagnetic waves affected as the frequency of the waves increases?

2 answers:

5 0

As the frequency is how many waves pass a fixed point in certain amount of times. This means that the waves get closer together and, therefore, the wavelength decreases. It also means that the wave has more energy.

Answer: D) Energy increases, wavelength decreases

A balloon is launched when the temperature is 15 oC and the pressure is 0.918 atm. Its volume is 11.1 L. It rises in the air unt

ivann1987 [24]

Answer:

The new volume is 7,606.96 Liter.

Explanation:

The combined gas equation is,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1$ = initial pressure of gas in the balloon = 0.918 atm

$P_2$ = final pressure of gas in the balloon = 0.0012 atm

$V_1$ = initial volume of gas in the balloon = $11.1 L$

$V_2$ = final volume of gas in the balloon = ?

$T_1$ = initial temperature of gas in the balloon = $15^oC=273+15=288K$

$T_2$ = final temperature of gas in the balloon = $-15^oC=273-15=258K$

Now put all the given values in the above equation, we get:

$\frac{0.918 atm\times 11.1 L}{288 K}=\frac{0.0012 atm\times V_2}{258 K}$

$V_2=\frac{0.918 atm\times 11.1 L\times 258 K}{288 K\times 0.0012 atm}$

$V_2=7,606.97 L$

The new volume is 7,606.96 Liter.

A block of ice has little thermal energy. If you place it in a warm room, it melts into warm liquid water, which has much more e

Naily [24]

Answer:

The energy to turn the ice into water:

The energy that is required to change the state of ice into a liquid is obtained in the form of heat energy from the ambient temperature of the warm room.
Once this heat energy is absorbed, the individual molecules of ice gain kinetic energy and start vibrating faster.
Yet, the temperature of the ice remains constant until the ice reaches its melting point because this energy is first utilised to break all the bonds of the lattice structure of the ice.
After all the bonds are broken and all of the ice has changed into water, if more heat is provided again, then the temperature of the water will increase.

Why can't polyatomic ions ever stand alone?

Basile [38]

The prefix "poly-" means "many," and "atomic" refers to atoms, so a polyatomic ion is made of 2+ atoms covalently bonded together. These ions are charged, which is why they can never stand alone.
