Answer:
The temperature rises by 0.52K
Explanation:
Detailed explanation and calculation is shown in the image below
Gravity is the energy due to Earth pulling down on an object.
The correct formula for calculating the tangential speed of an orbiting object is V(t)=wr.
V(t)= Tangential Speed
w= Angular Velocity
r= Radius of the Path
Hope this helps.
Answer:
Radius of cross section, r = 0.24 m
Explanation:
It is given that,
Number of turns, N = 180
Change in magnetic field,
Current, I = 6 A
Resistance of the solenoid, R = 17 ohms
We need to find the radius of the solenoid (r). We know that emf is given by :
Since, E = IR
or
Area of circular cross section is,
r = 0.24 m
So, the radius of a tightly wound solenoid of circular cross-section is 0.24 meters. Hence, this is the required solution.
Where the displacement is a maximum the pressure is a minimum.
Where the displacement is zero, the pressure is a maximum.
