Answer:
4 A
Explanation:
V = IR, where V=voltage, I=current, R=resistance. This is Ohm's Law. (remember that for units V = volts, Ω = ohms, A = amperes.)
V = IR
12 V = I * 3 Ω
12/3 = I
<u>I = 4 A</u>
Answer:
F = M a = M v^2 / R
If v is increased by three the force will be increased by nine,
C) is correct
NEPTUNE is the planet that takes the longest to orbit the Sun.
According to Kepler's law of harmonies, Planets closer to the Sun orbit it in a shorter time period than planets further from the Sun.
Planets arrangement from the Sun.
1) Mercury
2) Venus
3) Earth
4) Mars
5) Jupiter
6) Saturn
7) Uranus
8) Neptune
9) Pluto
So based on the given choices and arranged according to the longest to orbit to the shortest to orbit, the order would be: Neptune, Jupiter, Mars, and Venus
