the mass of two balls is 0.80 kg each and they are separated by 0.25 meters. calculate the gravitational
force between the two balls. the gravitational constant is 6.67 x 10-11 nm2
/kg2
(fg=g(m1m2/d2
)
a. 5.2 × 10-10 n
b. 6.8 × 10-10 n
c. 7.1 × 10-10 n
d. 2.4 × 1011 n

Aman tries to push a box of mass 4 kg with a force of 5 n but the box remains stationary if the coefficient of static friction is 0.45, what is the value of the maximum force of friction?

The plum pudding model of the atom states that ?

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
