Answer:
23.889 Celcius
Explanation:
(75°F − 32) × 5/9 = 23.889°C
The first one It sends signals that control heart rate and respiration. I hope this helps :)
Refraction is the change in direction of a wave.
Diffraction is the bending of a wave around a barrier.
Explanation:
It is known that electric field is responsible for creating electric potential. As a result, it depends only on the electric field and not on the magnitude of charge.
So, when a charge is increased by a factor of 2 then electric potential will remain the same. Since, expression to calculate the electric potential is as follows.
U = qV
Since, the electric potential is directly proportional to the charge. Hence, when 0.2
tends to replaced by 0.4
then charge is increased by a factor of 2. Hence, the electric potential energy is doubled.
Thus, we can conclude that if that charge is replaced by a +0.4 µC charge then electric potential stays the same, but the electric potential energy doubles.
