A centripetal force causes circular motion because it accelerates an object
2 answers:
Answer:
Towards the center of circle, which changes the direction of motion but not speed
Explanation:
The force acting on an object when it is moving in circular path is called centripetal force. The formula for centripetal force is given by :
Where
m = mass
v = velocity
r = radius of circle
In a circular path, the velocity of object changes continuously while its speed remains constant. The centripetal force acts towards the center of circle. Hence, the correct option is (a) " towards the center of circle, which changes the direction of motion but not speed ".

Answer:
(a) Initial volume will be 7.62 L
(b) Final temperature will be 303.85 K
Explanation:
We have given one mole of ideal gas done 3000 J
So work done W = 3000 J
Let initial volume is and initial pressure
( As pressure is constant )
Final volume = 0.025
Number of moles n = 1
(B) From ideal gas of equation we know that
So
T = 303.85 Kelvin
(B) For isothermal process work done is equal to
So initial volume will be 7.62 L
Answer:
The time interval is
Explanation:
From the question we are told that
The constant acceleration is
The displacement is
According to the second equation of motion we have that
given that the blade started from rest
which is the initial angular velocity is 0
So
=>
substituting values
=>
=>
