Which is an effect of the ozone depletion over Antarctica? A) loss of phytoplankton, the microscopic marine organisms that are the basis for the entire food chain B) increase in the incidence of skin cancer as a result of UVB radiation C) increase in damage to eyes leading to cataracts D) extensive DNA damage in the eggs and larvae of Antarctic fish E) all of the above

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

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.
