Answer:
450
Explanation:
Given,
Mass= 100kg
Velocity= 3 m/s
Kinetic Energy= ?
Kinetic Energy= 1/2 mv^2
= 1/2× 100× 3^2
= 1/2× 900
= 450.

Answer:
Tension and Gravitational Force
Explanation:
The question says that a monkey is hanging, he neither drops down to the ground nor moves up. He keeps hanging on a vertical vine.
Since, the monkey is hanging, two forces acts on the monkey, one force is due to his weight, i.e., the gravitational force which tends to pull him downwards and the other is due to the tension developed in the string which is in upward direction.
Thus to keep the monkey in the hanging state both the forces must counter balance each other and maintains the system 's equilibrium.
Therefore, both the forces must be equal.
True. That is how powerful the sun is. But it will explode in only about 5 billion years.

Answer:
Option B. N2(g) + 3H2(g) → 2NH3(g)
Explanation:
When nitrogen react with hydrogen, they form a product as shown below:
N2+ H2 → NH3
We need to balance the equation. This is illustrated below:
There are 2 atoms of nitrogen on the left side and 1 atom on the right side. To balance it, put 2 in front of NH3 as shown below:
N2+ H2 → 2NH3
Now, There are a total of 6 atoms of Hydrogen on the right side and 2 atoms on the left side side. This can be balanced by putting 3 in front of H2 as shown below:
N2+ 3H2 → 2NH3
Now we see clearly that the equation is balanced as we have equal numbers of atoms of N and H on both sides of the equation
