A thermocouple junction will respond to changes in the temperature of its surroundings more quickly than a mercury in-glass thermometer would. There are two reasons for this: a) the junction is smaller than the bulb full of mercury

b) the junction is not encased in glass

Explain why each of these factors helps the thermocouple to respond quickly.

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.
