100 POINTS FOR THE CORRECT ANSWER/ EXPLANATION.

d) 15.12 N

e) 15.12 N

Explanation:

Draw a free body diagram of the each block.

Block A has three forces on it: weight force mAg pulling down, normal force N pushing up, and tension force T pulling down.

Block B has two forces on it: weight force mBg pulling down, and tension force T pulling up.

Sum of forces on A in the y direction:

∑F = ma

T + N − mAg = mAa

N = mAa + mAg − T

N = mA (a + g) − T

Sum of forces on B in the y direction:

∑F = ma

T − mBg = mBa

T = mBa + mBg

T = mB (a + g)

Plug in values:

T = (1.80 kg) (-1.60 m/s² + 10 m/s²)

T = 15.12 N

N = (3.60 kg) (-1.60 m/s² + 10 m/s²) − 15.12 N

N = 15.12 N

So the answers to (d) and (e) are both 15.12 N.

answer: electrons

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
