Alamp is plugged into a standard 120-volt outlet. if the lamp draws a current of 0.5-amps, how much energy is consumed in 1 minute?

What is the average speed of a car that travels 40 mph for 1 hour and 60 mph in another hour?

Atomic nuclei of almost all elements consist of

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
