A person's weight will change if they move from the earth to the moon. This does not however, change the person's mass. Mass is the amount of matter that makes up an object, and volume is how much space it takes up. On the moon, there is a lighter gravitational pull on said person, so they will not weigh as much if they stepped on a scale.

Answer:

8.6*10^5N

Explanation:

Pressure of the water = density of water * height of the water * acceleration due to gravity

Pressure of water = 1000*9.81*(2.5 + 8.50)

Pressure of the water = 107910 = 1.08*10^5

And Pressure = force / A

Force = Pressure * A(surface area of the container)

Force = 1.08*10^5 * 8 = 863280 = 8.6*10^5N

**Answer:**

**28 degree C**

**Explanation:**

We are given that

We have to find the temperature on a spring day when resistance is 215.1 ohm.

We know that

Using the formula

Hence, the temperature on a spring day **28 degree C.**
