It used to take Andy 4 minutes a day to blow dry his hair in the morning using a 1,875W hair dryer. How much money will he save in one 30-day month now that he no longer has to blow
dry his hair? Use the rate of electricity is $0.0783/kwh.
Question 8 (2 points)
A resistance of 79 ohms has a current of 0.13 A through it. What is the voltage of the battery in volts?
a) 10.27 volts
b) 607.7 volts

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.
