Average mass of cloud drop is .003g Assuming that the scattering coefficient is 2.00 find the volume scattering coefficient of the cloud. If there is 881 W m-2 of solar radiation vertically incident on the top of the cloud which is 1.33 km deep find the transmitted radiation at cloud base.

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

real, smaller and upside-down.   so the answer should be b.

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.
