Answer:
Correct answer = (c) 1.0 uF
Explanation:
Capacitors in parallel = C₁ + C₂ + ...... + Cₙ
In this case, there are two capacitors of 0.5 uF
= 0.5uF + 0.5uF
= 1.0uF
The answer is c or d mainly d
Answer:
A. The upward pressure gradient force is balanced by gravity.
Explanation:
A. is correct because the pressure difference is actually generated by gravity. As in the following formula for the pressure at different points:
![p = p_0 + \rho g h](https://tex.z-dn.net/?f=p%20%3D%20p_0%20%2B%20%5Crho%20g%20h)
where
are the pressure at 2 points, ρ is the density of the fluid, g is the gravitational constant, and h is the height difference.
B is incorrect because friction in air is too small to make an effect.
C is incorrect because the Coriolis force is horizontal, not vertical.
D is incorrect because a difference of 500 hPa = 50000 Pa, this is half of the atmospheric pressure.
E is incorrect because temperature cannot generate force.
