Answer:
1.7x10^-10 N
Explanation:
F = G [(m_1)(m_2)]/(r^2)
F = force
G = Gravitational constant 6.67433x10^-11 (N*m^2)/kg^2
m_1 = mass first object
m_2 = mass second object
r = radius between the 2 objects
F = G[(2 kg*2 kg)/(1.25 m)^2]
F = 1.7x10^-10 N
Answer:
35/2 J/s
Explanation:
Just use the 2 formulas
Work done = Force * distance moved
Power = Work done/time
WD = 7 * 50 = 350
Power = 350 / 20
= 35/2 J/s
Explanation:
An electrified comb is charged comb ( let say by running it through the hair) and when it is brought in the proximity of pieces of paper, the pieces tend to cling to it. This happens because the charged comb induces an opposite charge in the paper pieces and as opposite charges attract each other, the pieces are clinged.
