Question

Ten liters of seawater weigh about 101 Newtons. How much would a 1,000-liter tank weigh? How much would a 2,000-liter tank weigh? (Hint: How much would 1 liter of seawater weigh?)

Answer 1

1000 -liters = 1010 Newtons.

2000-liters = 2020 Newtons.

Explanation:

Given that 10 liters of seawater weigh = 101 Newtons.

We need to find the number of Newtons in 1,000-liter tank and 2,000-liter tank.

10 liters = 101 Newtons.

Dividing both sides by 10, we get

`(10 \ liters)/(10) =( 101 \ Newtons)/(10)`

1 liter = 1.01 Newtons.

On multiplying both sides by 1000, we get

1 liter × 1000= 1.01 Newtons × 1000.

1000 -liters = 1010 Newtons.

On multiplying both sides by 2, we get

2× 1000 -liters = 2×1010 Newtons

2000-liters = 2020 Newtons.
