According to Charles law, if pressure remains constant, volume varies directly with temperature. so we can infer that :
So, we can use this formula to find out the final temperature of the gas ~
Note : Take temperature in Kelvin ( 100°C = 373 K )
Now, convert it to Celsius ~
i.e 746 - 273 = 473° C
So, the final temperature of the gas will be equal to 473° C
A cord is wrapped around the outer surface of the 8-kg disk. If a force of F = (1⁄4θ²) N, where θ is in radians, is applied to the cord, determine the disk’s angular acceleration when it has turned 5 revolutions. The disc has an initial angular velocity and radius from the center of the disc = 300 mm
Answer:
the angular acceleration = 205.706 rad/sec²
Explanation:
GIVEN THAT:
The disc mass = 8 kg
Force =
We are told that the given θ is in radians; Therefore; the when it has turned 5 revolutions; we have the θ to be:
Also;
the initial angular velocity
radius from the center of the disc = 300 mm = 0.3 m
Thus; the mass moment about the Inertia can be determined via the following expression;
Now to calculate the angular acceleration; we equate the sum of the moments acting on the Inertia;
SO:
Hence; the angular acceleration = 205.706 rad/sec²
