1 answer:
Explanation:
2. Power is defined as the rate of doing work. Mathematically, it can be given by :
Where
W is work done or energy
t is the time taken
3. The formula of potential energy can be given by :
Where
m is the mass of the object
g is the acceleration due to gravity
h is height
Hence, this is the required solution.

Answer:
Explanation:
Given
there is fix Quantity of gas i.e. mass of gas is constant
From ideal gas Equation
PV=nRT
(a) volume always increases is not true as Pressure can also be increased .
(b)If Pressure is constant along with mass then as Temperature increases, Volume also increases.
(c)true , Product of Pressure and volume depends upon temperature thus it also increases with temperature.
(d)Density of gas may or may not increases
As density is
volume may increase or decrease as temperature increase .
(e)false
as it clearly stated that quantity of fixed therefore there is no change in gas
Answer:
(a) 8.362 rad/sec
(b) 6.815 m/sec
(c) 9.446
(d) 396.22 revolution
Explanation:
We have given that diameter d = 1.63 m
So radius
Angular speed N = 79.9 rev/min
(a) We know that angular speed in radian per sec
(b) We know that linear speed is given by
(c) We have given final angular velocity
And
Time t = 63 sec
Angular acceleration is given by
(d) Change in angle is given by
