A 20.0 F capacitor initially charged to 30.0 uC is discharged through a 3.00 k resistor. How long does it take to reduce the cap
Maslowich

Answer:

t = 0.04159 s

Explanation:

when a capacitor and resister are connected in series. charge on its plates decreases exponentially

q = qo * e^{\frac{-t}{RC}}

where,

CHARGE q  =15.0 C

INITIAL CHARGE q_0 = 30.0 uc

Resistor R = 20.0 F

capacitor C  = 3.00

15 = 30* e^{\frac{- t}{(20* 10^{-6} * 3* 1000)}

t = 0.04159 s

Which statement is accurate about how the aurora borealis is formed?
g100num [7]

Answer:

When the electrons jump to a higher energy state, they release energy as electromagnetic radiation, light.

Explanation:

When the solar wind gets past the magnetic field and travels towards the Earth, it runs into the atmosphere. As the protons and electrons from the solar wind hit the particles in the Earth's atmosphere, they release energy – and this is what causes the northern lights.
