Answer:
Two objects that are the same volume will displace the same amount of water even if they have different masses.
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

Answer:
Part a)
Part b)
Here final kinetic energy is more than the initial kinetic energy
This increase in kinetic energy is due to spring connected between them as the spring energy is converted into kinetic energy of two blocks
Explanation:
Part a)
As we know that there is no external force on the system of two gliders
So here we can use momentum conservation for two gliders
So we will have
Part b)
now we will have
initial kinetic energy of both gliders is given as
Final kinetic energy of two gliders
so here final kinetic energy is more than the initial kinetic energy
This increase in kinetic energy is due to spring connected between them as the spring energy is converted into kinetic energy of two blocks
