Answer: D
Explanation:
A -amount of work
F-force
s-distance
If you keep same Force(F) and increase distance(s), amount of work will increase, according to:
A=F*s
Protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge).
Answer:
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
