Answer:
C) 160 N
Explanation:
= mass of the car = 2000 kg
Weight of the car is given as

= Force exerted on the input piston
= Area of input piston = 10 cm x 10 cm = 0.1 m x 0.1 m = 0.01 m²
= Area of lift = 1 m x 1.2 m = 1.2 m²
Using Pascal's law

Answer:
The answer to your question is: Ep = 14715 Joules
Explanation:
Data
mass = 50 kg
Potential energy = ?
height = 30 m
g = 9.81 m/s²
Equation
Ep = mgh
Substitution
Ep = (50)(9.81)(30)
Ep = 14715 Joules
As what Douglas Adams says, "<span>Space is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist, but that's just peanuts to space."
The fact that the stars are very far from Earth, one can't fully understand the stars as it would require hundred of years to closely travel from earth to the stars because it is located million miles away from the Earth. Aside from its location, the stars are also hard to closely study because it emits lights that are harm for people when exposed longer. </span>
Answer:
v = 40 [m/s].
Explanation:
Linear momentum is defined as the product of mass by Velocity. In this way, by means of the following equation, we can calculate the momentum.

where:
m = mass [kg]
v = velocity [m/s]
![P =20*10\\P =200 [kg*m/s]](https://tex.z-dn.net/?f=P%20%3D20%2A10%5C%5CP%20%3D200%20%5Bkg%2Am%2Fs%5D)
Since all momentum is transferred, we can say that this momentum is equal for the mass of 5 [kg]. In this way, we can determine the speed after the impact.
![v = P/m\\v = 200/5\\v = 40 [m/s]](https://tex.z-dn.net/?f=v%20%3D%20P%2Fm%5C%5Cv%20%3D%20200%2F5%5C%5Cv%20%3D%2040%20%5Bm%2Fs%5D)
Answer:
The value is 
Explanation:
From the question we are told that
The volume of liquid nitrogen is 
The density of nitrogen at gaseous form is
= The dry air at sea level
Generally the density of nitrogen at liquid form is

And this is mathematically represented as

=> 
Now the density of gaseous nitrogen is

=> 
Given that the mass is constant


=>
