<h2>Correct answer:</h2>
<h2>Explanation:</h2>
We can use voltage divider to solve this problem that is defined as the passive linear circuit producing an output voltage that is a fraction of its input voltage . So we can use the formula:
Internal energy<span> is defined as the </span>energy<span> associated with the random, disordered motion of molecules. It is denoted by U and calculated by the expression:
</span>Δ<span>U = Q - W
We calculate as follows:
</span>ΔU = 68 J - 32 J
ΔU = 36 J
Answer: 63 m/s
Explanation: If wheel drops vertically, you can use
conservation of energy : Ep = Ek. mgh = ½mv^2 and
solve v = √(2gh ) = √ (2·9.81 m/s²·200 m) = 62.6 m/s.
NOTE: wheel has also horizontal speed which was not mentioned here.
The answer is number 2 stomata.
