Answer: The energy of wave-y will more than the energy of wave-z. Since,frequency of wave-z is less than the frequency of wave-y

Explanation:

Let the frequency of the wave z be\nu

Given that frequency of wave y is about three times greater than the frequency of wave-z.

Then frequency of wave-y :\nu'

Frequency of wave-z is less than the frequency of wave-y:\nu'>\nu

The energy of the electromagnetic waves with frequency is given by:

E=h\times \nu, h= Planck's constant

E\propto \nu

Energy of the wave is directly proportional to the frequency of the wave.

The energy of wave-y will be more than the energy of wave-z. Since,frequency of wave-z is less than the frequency of wave-y

Frequency and energy have a direct relationshipWave Y transfers about three times the amount of energy as wave Z because energy and frequency have a direct relationship

Consider the following reaction
aliina [53]

Answer:

d, 40 dm3.

Explanation:

According to Avogadro's law, the mole ratio of chemicals in a reaction is equal to the ratio of volumes of chemicals reacted (for gas).

From the equation, the mole ratio of N2 : H2 : NH3 = 1 : 3 : 2, meaning 1 mole of N2 reacts completely with 3 moles of H2 to give 2 moles of NH3, the ratio of volume required is also equal to 1 : 3 : 2.

Considering both N2 and H2 have 30dm3 of volume, but 1 mole of N2 reacts completely with 3 moles of H2, so we can see H2 is limiting while N2 is in excess. Using the ratio, we can deduce that 10dm3 equals to 1 in ratio (because 3 moles ratio = 30dm3).

With that being said, all H2 has reacted, meaning there's no volume of H2 left.  2 moles of NH3 is produced, meaning the volume of NH3 produced = 10 x 2 = 20 dm3. (using the ratio again)

1 mole of N2 has reacted, meaning from the  30dm3, only 10 dm3 has reacted. This also indicate that 20 dm3 of N2 has not been reacted.

So at the end, the mixture contains 20dm3 of NH3, and 20 dm3 of unreacted N2. Hence, the answer is d, 40 dm3.

8. Thermal Energy is?
Burka [1]

Thermal energy is the sum of the kinetic and potential energy of all the particles in an object. The figure shows that if either potential or kinetic energy increases, thermal energy increases.

hope it really helps...!!!
