Answer:
A. The volume occupied by the molecules can cause an increase in pressure compared to the ideal gas.
D. As attractive forces between molecules increase, deviations from ideal behavior become more apparent at relatively low temperatures.
Explanation:
as we know by real gas equation
while ideal gas equation is given as
so from above formula we can say that net pressure is increased in real gas
Also we know that all real gas will close to behave like ideal gas when the pressure of the real gas is low and temperature of the gas is high
So above are the correct observations
Answer:
The acceleration at the moment the train speed reaches 52 kilometers per hour is approximately 1.826 meters per square second.
Explanation:
According to Rotational Physics, the total acceleration of the train rounding the horizontal turn is a combination of tangential () and radial accelerations (
), measured in meters per square second. The former one represents the change in the magnitude of the velocity, whereas the latter one represents the change in its direction. By definition of magnitude and Pythagorean Theorem we get that magnitude of total acceleration (
), measured in meters per square second, is:
(Eq. 1)
Magnitudes of tangential and radial accelerations are determined by using the following formulas:
(Eq. 1)
(Eq. 2)
Where:
,
- Initial and final speeds, measured in meters per second.
- Time, measured in seconds.
- Radius, measured in meters.
If we know that ,
,
and
, then the magnitude of the total acceleration when the train speed reaches 52 kilometers per hour is:
The acceleration at the moment the train speed reaches 52 kilometers per hour is approximately 1.826 meters per square second.
