Answer:
A. Their same forces repel each other, and their opposite forces attract each other.
Explanation:
As we know by the property of electric charge that similar charges repel each other and opposite charges attracts each other
So here we have similar situation in magnets also
Two similar poles or like poles of magnet i.e. North - North poles or South - South poles always repel each other
And also we can see that opposite poles of magnet each other i.e. North pole and south pole always attract each other.
SO here correct answer is
A. Their same forces repel each other, and their opposite forces attract each other.

Explanation:
F=5.6×10^-10N
R=93cm=0.93m
let take m1 and m2 =m²
according to newton's law of universal gravitation
F=m1m2/r²
F=m²/r²
now we have to find masses
F×r²=m²
5.6×10^10N×0.93m=m²
5.208×10^-9=m²
taking square root on b.s
√5.208×10^-9=√m²
so the two masses are m1=7.2×10^-5
and m2=7.2×10^-5

Answer:
Objects that have like charges attract each other.
Objects that have opposite charges repel each other.
When fur is rubbed on the balloon electrons move from the balloon to the fur.
This is because the balloon's material is an insulator.
Electrons have negative charge.
Protons have a positive charge.
neutrons have no charge.
Explanation:
This question deals with the volume of different shapes.
a) volume of the sphere is "33.51 m³".
