The pressure would increase as per Charle's Law, therefore the correct answer is option 4.
<h3>What is an ideal gas?</h3>
It is an imaginary gas for which the volume occupies by it is negligible, this gas does not exist in a practical situation and the concept of an ideal gas is only the theoretical one,
PV = nRT
As given in the problem statement we have to find out if the volume is held constant then what would happen to the gas if the temperature is increased,
For constant volume, the pressure of a gas is directly proportional to the temperature of the gas,
Thus, the pressure would increase as per Charle's Law, therefore the correct answer is option 4.

Answer:
a) 16.46 seconds.
b) 13.46 seconds
c) 2.67 m/s²
Explanation:
Acceleration = a = 1.35 m/s²
Final velocity = v = 80 km/h = 
Initial velocity = u = 0
Equation of motion
Time taken to accelerate to top speed is 16.46 seconds.
Acceleration = a = -1.65 m/s²
Initial velocity = u = 80 km/h=
Final velocity = v = 0
Time taken to stop the train from top speed is 13.46 seconds
Initial velocity = u = 80 km/h=
Time taken = t = 8.3 s
Final velocity = v = 0
Emergency deceleration is 2.67 m/s²
Answer:
- The process of comparing unknown quantities with known quantities is called measurement .
If it measurement system were not established ,then there may create lots of problem such as: unequal measure ,anyone can get more ,or anyone can get less mass ,so on .
Answer:
12m/s
Explanation:
v^2=u^2+2as
v=?
u=0 (the dish was stationary before it fell)
a=9.81 m/s^2 (acceleration due to gravity/freefall)
s=1.5m (the drop height)
So: v^2=0+2.9.81.1.5 = 144.35415
and therefore v=sqrt 144.35415
12x12=144 so I'd say v=12m/s
