Find the average translational kinetic energy and the rms speed of the o2 molecules in air at room temperature (20°c). [hint: the atomic mass of oxygen is 16.0 g/mol.]

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

a=d/t

a="triangle"v/t

explanation:

a = acceleration

a 2,000 calorie based diet.

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.
