An action-reaction pair would be a pair in which one of the elements exerts a force on the other element (action), and then the other element would respond to this force by exerting another force in the opposite direction (reaction).
From the given choices, we will see that:
For choice A, the moon exerts a force on the earth by pulling it (action) and the earth responds to this force by pulling the moon (reaction in opposite direction of the action).
Therefore, the correct choice would be:
A. <span>The Moon Pulls on Earth, and Earth pulls back on the moon.</span>
Light travels at the speed of 186,000 miles per second. If you were to travel around the earth it would be 7.5 times in a second
Answer:
Explanation:
a.
b. R3= 1/2R2=6 ôm
R12= R1+R2=20 ôm
Rtđ=R12.R3/R12+R3= 4,62 ôm
c. U= I.Rtđ = 2.4,62=9,23 V
I1=I2= 9,23/20= 0,4615 A
I3= 2-0,4615=1,5385 A
Answer:
C. Both A and B
