Can you explain how to solve each pleade

Explanation:

The resistance column is correct.

I1 = I2 = I3 = I4 = 2 Amps

So all the currents are the same.

R = 110

I = 2 amps

V = ?

Vt = I * R

Vt = 2 * 110

Vt = 220

V1 = 20 * 2 = 40 volts. That's 40 volts dropped from the right side of R1 to the left side.

V2 = 60 * 2 = 120 volts across the 60 ohm resistor

V3 = 30 * 2 = 60

Total voltage = 40 + 120 + 60

Total voltage = 220 which is just what it should be.

Power

P1 = V1 * I

P1 = 40 * 2

P1 = 80 watts

P2 = 120*2

P2 = 240

P3 = 60 * 2

P3 = 120

Total Power = 80 + 240 + 120

Total Power = 440

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
