The difference in electric potential between a thunder cloud and the ground is 1.53 108 V. Electrons move from the ground which
Kryger [21]

Answer:

=−2.451 330 152 1*10^27J

Explanation:

The electric potential=the Voltage * Charge: 

E = VQ

V = 1.53x10^8 V (positive, because the cloud has a higher potential)

Q = -1.60217657 x10^19 C (the charge of an electron)

E = (1.53x10^8 V )* (-1.60217657 x10^19 C)

E=−2.451 330 152 1*10^27J

The negative sign indicates that the potential energy is decreased by the movement of the electron.

"Asteroid" is the name we give to the huge number of small bodies
that orbit the sun, here in the inner solar system.

Their orbits are scattered all over the place.  Most of them spend
most of the time between the orbits of Mars and Jupiter, but there are
many asteroids that sometimes come very close to Earth.

this is a 3 part questionOn vacation, your 1400-kg car pulls a 560-kg trailer away from a stoplight with an acceleration of 1.85
mamaluj [8]

ANSWER:

(a) 1036 N

(b) -1036 N

(c) 2590 N

STEP-BY-STEP EXPLANATION:

Given:

Mc = 1400 kg

Mt = 560 kg

a = 1.85 m/s^2

(a)

Force by car on trailer:

\begin{gathered} F_c=m\cdot a \\ F_c=560\cdot1.85 \\ F_c=1036\text{ N} \end{gathered}

(b)

\begin{gathered} F_t=-F_c \\ F_t=-1036\text{ N} \end{gathered}

(c)

\begin{gathered} F_n=1400\cdot1.85 \\ F_n=2590\text{ N} \end{gathered}
