What is the gravitational force between two bowling balls with 7kg mass each and 1.1m apart ?

2.7010 * 10^-9 N

Explanation:

solution;

mass (m1) = 7kg

mass (m2) = 7kg

distance(d) = 1.1m

universal gravitational constant (G) = 6.67 * 10^-11

we know that,

gravitational force = (G*m1*m2)/d^2

= ((6.67 * 10^-11) *7 *7)/(1.1)^2

=(3.2683 *10^-9)/1.21

= 2.7010 * 10^-9

Gravitational force = 2.7010 * 10^-9 N

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.

answer; /// the above statement is (true);
