An iron ball and anauminum ball of mass 100 g each are hested to the same temperature and then coolectoatempered 20°C The heat lost by the iron balis 36 10. The heat lost by the animum balls 72 at this in
The specfichest of iron is greater
The specfic heat of aluminum is greater
The iron ball was hected to a higher temperature
D
The aluminum ball was heated to a higher temperature

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.

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.
