A 10.0-V battery is connected to a 120-Ω resistor. Ignoring the internal resistance of the battery, calculate the power delivered to the resistor.

0.83W

Explanation:

Given parameters:

Voltage of the battery  = 10V

Resistance  =  120Ω

Unknown:

Power delivered by the resistor = ?

Solution:

The power delivered by the resistor can be derived using the expression below;

 Power =  

V is the voltage

R is the resistance

 Now, insert the parameters and solve

  Power  =   = 0.83W

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
