AI Thread Summary
To estimate the power generated by a person climbing stairs, one must consider the energy expended over time. Power is defined as energy per unit time, so calculating the work done against gravity provides a basis for estimation. While the exact energy from metabolic processes is difficult to quantify, an approximation can be made using the change in gravitational potential energy as the person ascends. This approach assumes a constant climbing speed, simplifying the calculations. Understanding these principles allows for a reasonable estimation of the power output during stair climbing.

Can anyone give me an idea on how to estimate the amoung of power that a normal person will general as he climbs stairs?

Power is energy in unit time.Estimate the time in which energy is being expended and that amount of energy.

But how about energy?

How can I estimate energy?
 
Unfortunately,u can't estimate the real energy involved,namely the energy released from the chemical reactions that take place in your body while u're climbing that ladder.But you can approximate (i don't know how accurate,though) that with the work done by your body against gravity (equivalently,the variation in gravitational potential energy of your body),assuming you climb at constant speed wrt the ground...

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...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
