Answer - 12,900 Newtons
Explanation
First, we find the volume of the water
Volume = Area * Heinght
= 1.5 m² x 7 m
= 10.5 m³
Covert the volume to liters
1 m³ of water = 1000 liters
10.5 m³ of water = 10.5 m³ * 1000 liters liter/m³
= 10,500 liters
Use the volume of water to calculate the mass
1 liter of water weighs 1 kg
10,500 liters of water = 10,500 * 1 kg/liter
= 10,500 kg
Now, we can calculate the force of gravity on the water
Force of gravity on the water = Weight of the water
Weight = Mass * Acceleration
Mass = 10,500kg
Acceleration (due to gravity) = 9.8 m/s²
Force of gravity on the water
= Weight of the water
= Mass * Acceleration
= 10,500 kg * 9.8 m/s²
= 102,900 Newtons
Answer:
See the explanation below.
Explanation:
A lever is a simple machine that changes the magnitude and direction of the force applied to move an object. Minimizes the force needed to lift the object.
By means of the following image, we can see the principle of operation of a lever.
The load can be moved thanks to the force multiplied by the distance to the fulcrum.
