Answer:
1.17 x 10^2 L
Explanation:
We can find the volume of the gas by using the ideal gas law:
where we have:
is the pressure
V is the volume
n = 4.8 mol is the number of moles
R = 0.0821 L · atm/mol · K is the ideal gas constant
is the temperature
Solving the equation for V, we find the volume
Answer:
If an object moves twice as fast its kinetic energy quadruples.
Explanation:
The kinetic energy (K₁) of a body of mass (m) that moves with speed (v) is:
K₁= 1/2 * m* v²
If we double the speed of the body, its kinetic energy (K₂) will be:
K₂= 1/2 * m*( 2v)²
K₂= 1/2 * m* 4 *v²
K₂= 4(1/2 * m *v²)
K₂= 4*K₁
It lasts 29 1/2 days.
-the sidereal month- is the true period of the moon's revolution around Earth. It lasts 27 1/3 days.
-the difference of 2 days between the synodic and sidereal cycles is due to the Earth- moon system also moving in an orbit around the sun.
