Answer:
There is no way of knowing the phase composition without more information
Explanation:
For equilibrium to be established quantity of heat loss by the water must equal to the quantity of heat gain by the ice since the container is insulated which rules out loss of heat to the environment. To be able to the determine the phases present we need the temperature of the water as well as the temperature of the ice, mass of the water present and the mass of the ice . These two are not given, we therefore do not have enough information to determine the phases present even when we can easily get the values of specific heat capacity and latent heat of fusion.
Answer:The parallelogram rule asks that you put the tails (end without the arrow) of the two vectors at the same point, (just the a vector and b vector on the left of the diagram) then it asks you to close the parallelogram by drawing the same two vectors again (the b vector and a vector to the right of the diagram).
Explanation:
The halo extends farther from the nucleus
Answer:
Energy of a photon is
Explanation:
Given:
Frequency of the photon is, .
Energy of a photon of frequency is given as:
, where, is called Planck's constant.
So, energy of a photon is:
Therefore, the energy of a photon whose frequency is Hz is .
Answer: when an object begins to fall its potential energy decreases and it’s kinetic energy increases, potential energy is equal to kinetic energy because a decrease in potential energy is exactly equal to the increase in kinetic energy.
