¿Una bombilla de 50 vatios transfiere mas energía por unidad de tiempo que una bombilla de 100 vatios? Does a 50-watt light bulb transfer more energy per unit of time than a 100-watt light bulb?​

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?

Which type of energy would have nothing to do with ironing clothes? a. heat b. chemical c. electrical d. mechanical

Which of the following are forms of phase changes a. freezing b. condensation c. heating d. exchanging
