30 points to the first correct answer(btw they need to add a simple science subject). when a frying pan containing an uncooked egg is placed on the stove top and the electric burner is turned on, the egg then cooks. what is the source of heat energy of the cooking egg? electrical energy from the power socket newly created energy that was not present earlier newly created energy that increased the total energy mechanical energy from the heating element in the kettle

Electrical energy from the power socket

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.
