Answer:
its density decreases it volume increases
Explanation:
When water turns to ice, it expands / contracts. Water is more / less dense than ice. The water you drink is a solid / liquid / gas.
Answer:
1.It helps in trade and business.
2. It helps to perform scientific calculations.
Answer:
option A
Explanation:
given,
diameter of circle = 10 ft
refractive index of the water = n = 1.33
let the inclined surface of the cone makes an angle θ with vertical line then
we know,
from this θ = 48.75°
substitute this in eq ( 1 ) we have
h = 4.38
h = 4.4 (approx.)
Hence, the correct answer is option A
A fixed container containing an ideal gas is heated. The pressure of the gas increases because the molecules move faster.
You can speed up the motion of the molecules in a gas by heating it. The pressure will rise and there will be greater impacts on the container's walls.
The container walls are pressed against by the combined force of the collisions. The energy you provide when you heat the gas makes the gas's particles more kinetically energetic and put more pressure on the container.
As the temperature rises, the pressure must as well since pressure is the force the particles per unit of area exert on the container.

Answer: 0.064 m/s²
Explanation:
Initial velocity = 22m/s
Final velocity = 44m/s
Time taken = 345 seconds
Acceleration = (Final velocity - Initial velocity) / Time taken
= (44 - 22) / 345
= 22/345
= 0.0637681
= 0.064 m/s²
Therefore, the acceleration is 0.064 m/s².
