AI Thread Summary
A 1.1 HP air compressor motor consumes 825 watts of power. Operating for 5.6 hours daily equates to 20,160 seconds. The total energy consumed by the motor is calculated as 16,632,000 joules. The discussion clarifies that the question pertains to energy consumption rather than work. Understanding that watts measure energy per second is crucial for this calculation.

Homework Statement


A small air compressor operates at 1.1 hp electric motor for 5.6 hours a day. How much energy is consumed by the motor daily?


Homework Equations



1hp = 750 watts
power=work/time
work=force*distance

The Attempt at a Solution


1.1hp= 825 watts
5.6 h=20160s
power*time=work
(825w)(20160s)=16632000J I'm confused on what the question is asking for, is it asking for work?

What you've done is correct. A Watt is one joule per second, thus your answer is in joules and is therefore a value for energy. Work is just the change in energy of an object.
 

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...
