. Two lenses, separated by a distance of 50.0 cm are used in combination. The firstlens, located to the left, has a focal length of 15.0 cm. The second lens, located tothe right, has a focal length of 12.0 cm. An object, 3.0 cm high, is placed a distanceof 20.0 cm in front of the first lens. What is the total magnification

jupiter

explanation:

it is so massive and has such a strong gravitational pull its likely prevented the formation of a planet between itself and mars in the asteroid belt

hey , the answer is c

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.
