Answer:
The force needs to be applied on the 1 square meter piston to lift the machine is 200 N.
Explanation:
Given that,
Force, 
Area, 
We need to find the force needs to be applied on the 1 square meter piston to lift the machine. We know that the pressure at every point is same due to Pascal's law such that :
So, the force needs to be applied on the 1 square meter piston to lift the machine is 200 N. Hence, this is the required solution.
The sound waves travel through the sea which creates movement which can be felt all the way in Italy in the sea- like a domino effect
C isotopes is the correct answer. Isotopes are variants of a particular chemical element which differ in neutron number, and consequently in nucleon number.All isotopes of a given element have the same number of protons but different numbers of neutrons in each atom.
Hope this helps! :)
The weight of an object is taken to be the force on the object due to gravity. The weight ( W ) is the product of the mass ( m ) of the object and the magnitude of the gravitational acceleration ( g ).
On Earth: g = 9.81 m/s²
m = 20 kg
W = m · g = 20 kg · 9.81 m/s² = 196.2 N
Answer by mimiwhatsup: B) Velocity is a vector and requires a direction to completely describe it.
