Q5.
<span>The
answer is A. In thermodynamics, the first
law of conservation states that energy can never be destroyed or created but
can only be transformed from one form to another. Therefore part of the
electric energy was converted to light energy while the other dissipated as
heat. However, the summation of the energy
of these tow outputs in joules remains
the same as initial electric energy.

Q6
<span>The answer is B. This is because
the water in the dam is used to turn turbines hence this form of energy is mechanical energy. As the turbines turn, they
turn electromagnets that convert the mechanical energy into electrical energy</span>
Tobias drank from a contaminated water fountain
Answer:
because theyre in our bodies and they have to be small to be in our bodies
Explanation:
Answer:
The right answer to this question is: 310k
Explanation:
There's a very good formula that can help us to find this answer, but first, we need to know the temperature scale in Celsius and Kelvin, there's an image below that will help us gather information.
The formula is quite simple, check it below:
C/5 = K-273/5
putting the values we already have in the formula it would be like this:
37/5 = K-273/5
Cutting out the fives, we can have the final result
37= K-273
37+273 = K
K= 310.
