Semi-empirical mass formula: also known as bethe-weizsacker mass formula is given as m(z, a) = n mn + z mh - b(z, a) (a) using the semi-emperical mass formula obtain the separation energy for a neutron sn and seperation energy for a proton sp. you can assume that z and n are large. (b) using the expressions obtained above find the sp and sn for sn116.

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

answer; how far out of place which the object finished relative to the starting location;

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.
