Answer is 10N to the left
To find the resultant resultant force, subtract the largest force (35N to the left) by the smallest force (25N to the right).
35 – 25 = 10N
It would be 10N to the left because the force exerted to the left is larger than the force exerted to the right.
Answer:
18 ohms
Explanation:
V = I(R1 + R2)
5V = (0.167A)(12 ohms + R2)
Solving for R2
R2 = 18 ohms

A crystalline solid that conducts current under certain conditions
It’s newton’s 2nd law of motion
Answer:
66.7%
Explanation:
There are 6 pulleys, so the mechanical advantage is 6.
The theoretical force needed to overcome 1200 N is therefore:
1200 N / 6 = 200 N
The actual force is 300 N. So the efficiency is:
200 N / 300 N × 100% = 66.7%
