Answer:
By polishing the surface, as polishing makes the surface smooth and friction can be reduced
Explanation:
The correct answer is A. Each object in the universe that has mass attracts every other object that has mass.
Explanation:
The gravitational law proposed by Newton explains how the gravitational force works. The basic idea or premise in this law is that the gravitational law exists in all the universe, and occurs with all objects that have a mass. This includes the fact all objects or particles that have a mass attract all other objects with mass but this is also influenced by the distance between the objects, and the masses of each object. In this way, the gravitational force is equal to the gravitational constant multiplied by the mass of the two objects and divided by the distance between the objects.
Answer:
Coefficient of friction is 
.
Work done is 
.
Explanation:
Given:
Mass of the box (
): 
kg
Force needed (
): 
N
The formula to calculate the coefficient of friction between the floor and the box is given by
Here, 
is the coefficient of friction and 
is the acceleration due to gravity.
Substitute N for , kg for and 
m/s² for into equation (1) and solve to calculate the value of the coefficient of friction.
The formula to calculate the work done in overcoming the friction is given by
Here, 
is the work done and 
is the distance travelled.
Substitute N for and 
for into equation (2) to calculate the work done.
