Suppose that a block is pulled 16 meters across a floor. what amount of work is done if the force used to drag the block is 22 n? a. 352 j b. 200 j c. 220 j d. 330 j

W = 352 J

Explanation:

It is given that,

The force used to drag the block, F = 22 N

Displacement of the block, d = 16 meters

The work done is given by the product of the force and the displacement :

W = F . d

W = 22 N × 16 m

W = 352 Joules

The amount of work done to drag the block is 352 Joules.

Hence, the correct option is (A) " 352 J ".                        

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h

happy to

pls mark as brainliest

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
