Options:
- NaOH(aq)
- NaOH(l)
- N2(g)
- NO(g)
Answer: <em>NaOH (aq)</em>
Explanation:
Defining state terminologies, '<em>aq' </em>means aqueous, meaning the analyte is in solution, as opposed to gaseous (g), or liquid (l).
Answer:
Newton's First Law states that an object in motion will stay in motion, an object at rest will stay at rest, at a constant velocity, unless an unbalanced force acts upon it.
Newtons First law of motion has to do with seat belts because think about it, what happens when we don't wear a seat belt and our vehicle comes to a quick stop. What happens to you? You move forward and stay in motion until an unbalanced force acts upon you. Now what is an unbalanced force? An unbalanced force is one that is not opposed by an equal and opposite force operating directly against the force intended to cause a change in the object's state of motion or rest. So, when you come to a stop, you wouldn't stop motion unless a force is caused to change your motion and put you at rest. If you were wearing a seat belt, the seat belt would act as the unbalanced force, it would stop you from being in motion.
I think the answer would be the last option. The difference between the energy transformations in power plants and dams would be that dams are the ones who uses mechanical energy to produce electricity. It uses turbines to convert mechanical to electrical.
Answer:
The order of the energy of the photons of given wave will be
= Ultraviolet waves > infrared waves > microwaves
Explanation:
where,
E = energy of photon
= frequency of the radiation
h = Planck's constant =
c = speed of light =
= wavelength of the radiation
We have :
(a) Frequency of infrared waves =
(b) Frequency of microwaves=
(c) Frequency of ultraviolet waves =
So, the decreasing order of the frequencies of the waves will be :
As we can see from the formula that energy is directly proportional to the frequency of the wave.
So, the order of the energy of the photons of given wave will be same as their order of frequencies:
= Ultraviolet waves > infrared waves > microwaves
