Answer:
The gas pressure is: 1.55 atm.
Explanation:
We need to use the equation that relate the variables given at the exercise (pressure, temperature and volume) from the ideal gas law formula, when the mass is constant we can reduce the expretion 
to 
solving to P2 we get:
replace the values 
.
Answer:
On Earth, flowing of liquid metal in the outer core of the planet generates electric currents. The rotation of Earth on its axis causes these electric currents to form a magnetic field which extends around the planet.
The force of Earth's gravity on you is greatest when you stand as
close as you can to the center of the Earth (but not underground).
From the choices listed, that would be (c).
(last choice)
The speed increases from X to W because a component of the gravitational force acts in the direction of the velocity.
