The spectral lines of a 1 solar mass star have a random noise shift of 1 ms due to the effects turbulence in the star. how close would an earth-mass planet have to be to the star so that the -1 planet's radial velocity would exceed the natural 1 ms radial velocity jitter by a factor of 2? how long would the year be if the planet were this close to the sun?

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

a is the best answer your welcome

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.
