Just as Prof. Newton said: "For every action, there is an EQUAL, OPPOSITE reaction.". (See his motion law #3.)
If our person APPLIED a force of 80N pointing to the right, then that's the 'action'. It must follow, as the night follows the day, that the strength of the equal REaction is also 80N, and it points to the left because it's opposite to the action.
Answer:
<em>1 Volt</em>
<em></em>
Explanation:
The resistors have resistance R = 1 kΩ each = 1 x 10^3 Ω each
The current through the voltage source I= 2 mA = 2 x 10^-3 A
The resistors are in parallel, son the total resistance will be
= 
= 1/1 kΩ + 1/1 kΩ
= 2/1 kΩ
= 1 kΩ ÷ 2 = 0.5 kΩ = 500 Ω
From V = IR
where V is the voltage
I is the current
R is the resistance
substituting, we have
V = 500 x 2 x 10^-3 =<em> 1 V This is the voltage across each resistor</em>

Answer:
The earth has a larger mass and therefore more inertia.
Explanation:
<span>The magnitude of the gravitational force between two bodies is the product of their masses divided by the square of the distance between them. So we have F = M1*M2 / r^2. M1 = 7.503 * 10e24 and M2 = 2.703 * 10e22 and r= 2.803 * 10e8; r^2 = 5.606 *10e16. So we have 7.503 *2.703 *10^(24+22) = 20.280 * 10^(46). Then we divide our answer by 5.606 * 10e16 which is the distance ; then we have 3.6175 * 10 e (46- 16) = 3.6175 * 10e30.
To find the acceleration we use Newton's second law F = ma. F is 3.6175 * 10e30 and M is 7.503 * 10e24 so a = F/M and then we have 3.6175/7.503 * 10e (30-24) = 0.48 * 10e6.
Similarly for moon, we have a = 3.6715/2.703 * 10e(30-22). = 1.358 * 10e8</span>
