Rate of change in temperature. Another way to do this?

AI Thread Summary
The discussion centers on solving a physics problem related to temperature change and energy transfer. The user has successfully calculated the rate of change in temperature using basic equations but is inquiring about a potential calculus-based approach. However, it is noted that the rate of change is constant, and the method used is deemed sufficient. The response confirms that no advanced calculus is necessary for this problem. Overall, the original solution is validated as effective.

Homework Statement


[/B]
My question is regarding Part B of this problem, I have solved it but I'm wondering if there is another way to solve it since it says dtheta/dt and one of the hints I found online suggested that I use the chain rule.

Homework Equations


Q = mc(deltaT)
Q/t = P

The Attempt at a Solution



For the first part, i just did theta/time to find angular velocity, then multiplied by radius to find the tangential velocity, then just multiplied by the force of 520N by pi/9, the tangential velocity to get 180 Watts.

For the second part I just divided the equation for Q by t to make deltaT/t=P/mc and got 0.064 C/s.

If there was a calculus way to solve this I'd appreciate some help. Thanks

There's no calculus of any interest here, the rate is constant. Your method is as good as any.
 
makes sense. thanks haruspex
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
