Explanation:
Basically 9,875 - what will give you 8,430 that's what's its asking. Its just a gap.
Answer:
500 joule
Explanation:
given,
mass(m)= 5kg
height(h)= 10m
acceleration due to gravity(g)= 10m/s^2
potential energy =?
We know that,
potential energy = mgh
= 5×10×10
= 500 joule
The answer is Weathering since its nature breaking down the concrete.
Answer:
An Object is positively charged if it has more Positive Electrons in that object
Explanation:
Magnet: It has two poles: South pole and North pole.
Magnetic field lines are stronger near the poles of the magnet.
Same poles repel each other. There is a magnetic force of repulsion between the same poles. North- North poles repel each other.
Unlike poles attract each other. There is magnetic force of attraction between the opposite poles. South- North poles attract each other.
Mono poles cannot exist.
From the given statements, the magnetic poles are described by:
A north pole must exist with a south pole.
Two south poles placed near each other will repel each other.
A north pole and a south pole placed near each other will attract each other.
