AI Thread Summary
The discussion centers on expressing power in terms of electric charge, current, and voltage. It clarifies that power, defined as the product of voltage and current, simplifies to J/s, which is equivalent to watts. The participant expresses confusion about the question's intent, but it is confirmed that the derived result correctly shows that power is measured in watts. The simplification process is validated, indicating that the initial understanding of the relationship between the units is accurate. Ultimately, the participant has successfully arrived at the conclusion that power is measured in watts.

Homework Statement


Given that the unit of current is related to the units of electric charge and time by A = C/s, and the unit of voltage is related to the units of energy and charge by V = J•C^-1, express the power in terms of these other units. Simplify the result further, given that the watt (W) is defined by W = J/s


Homework Equations


A = C/s
V = J•C^-1


The Attempt at a Solution


W = C/s • J•C^-1
W = J/s

Now what? I don't understand what the question is asking.

They seem to be asking that since power is voltage times current, then it has units of J/s. Since a J/s is a watt, power has units of watts. You actually have the result.
 

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}...
