PLEASE HELP!! Analyse 2 parallel resistors in series with 1 other resistor
In the circuit diagram shown in the
where R1 =112, R2 =4 12 and R3 =4 2.
calculate the power dissipated in watts to 1 decimal place in R2.

Which statement best describes resistance? resistance is a. how well a current will flow in a material and is measured in volts. b. how well a material conducts an electrical charge and is measured in ohms. c. the ability of a material to attract a positive charge to create a current. d. the ability of a material to repel neutral charges and is measured in ohms.

Using a wheel and axle, a farmer is trying to lift a bucket of water from the bottom of a well. the larger wheel has a radius of 40 cm compared to the axle that has a radius of 10 cm. if a bucket of water is 50 n, then how much effort is required to raise it? 12.5 n 200 n 2 n 500 n

Which lists the pairs of plates in order from least to greatest in terms of the work done to move the electron?
