A box of bananas weighing 40.0 N rests on a horizontal surface. The coefficient of static friction between the box and the surfa
Burka [1]

Answer:

(a) = 0 N

(b) = 2.4 N

Explanation:

given

box of banana weight = 40.0 N

coefficient of static friction  μ = 0.40

coefficient of kinetic friction = 0.20

a).  when no horizontal force is applied .

according to Newton 's third law of motion If there is no force applied to the box,so the frictional  force exerted is 0 N

b) magnitude of friction force

box and the box is initially at rest

    friction force =.Static friction coefficient × weight of the box

      friction force = 0.40 × 6

       friction force =  2.4 N

Which statement about a pair of units is true?
grandymaker [24]

Answer:

option A is correct as 1 yard consist of 0.9144 meter which is less than one meter

Explanation:

from the above given statement option 1 is true

1 yard is equal to 0.9144 meter

while

1 mile is equal to 1.60934 km

1 foot is equal to 30.48 centimeter

1 inch is equal to 2.54 centimeter

therefore all these units [left one] are larger than their respective conversion [ right one unit]

therefore option A is correct as 1 yard consist of 0.9144 meter which is less than one meter
