Answer:
Explanation:
Mass of the Sun = 
Amount of Hydrogen = 75% of Mass of Sun,
thus mass of Hydrogen (m) in the Sun is,
m = 
Speed of Light (c) = 
Thus, energy(E) produced if whole of hydrogen is converted into energy,
E = mc²
There are two types of forces
1. Physical force : in this type of forces we require direct contact between two bodies
2. Field force: here we do not requires any type of physical contact with the body
so here in this type of field force we do not required any contact but only due to field present near it the body can move
so here several examples are there
a) when a magnet is placed near a piece of iron then it will move towards the iron
b) a positively charged particle when come near another charged particle then it will get attracted or repelled.
so as per all above discussion we can say that an object can move without any direct contact
Answer:
x₂ = x₁ + v₁t + at²/2
Explanation:
Right out of the textbook.
That would be the dump truck. Momentum depends on how heavy a certain object is in motion. The more weight it has the harder it is to stop.
