Answer
given,
initially rotating speed = 130 rad/s
final rotating speed = 0 rad/s
constant acceleration = 3 rad/s²
a) using equation of rotating acceleration
3 t = 130
t = 43.33 s
time does the disk take to stop is equal to 43.33 s
b) again using equation of rotation
angle does the disk rotate during that time is equal to 2817 rad
Answer:
2.771208%
Explanation:
= Change of volume
= Initial volume
= Change in temperature = (0.3-1050)
= Volumetric coefficient of thermal expansion =
Volumetric expansion of heat is given by
Finding percentage
The ratio of change of volume to initial volume is 2.771208%
The body system on the chart
Answer:
V₂=153.84 m L
Explanation:
Given that
Initial volume ,V₁ = 200 m L
Initial pressure ,P₁= 500 torr
Final pressure P₂ = 650 torr
Lets take the final volume =V₂
Given that process occurs at constant temperature and we know that for constant temperature process
P₁ V₁ = P₂ V₂
Now by putting the values
V₂=153.84 m L
Therefore the new volume of the gas will be 153.8 4mL.
