The force of the car increases because it is proportional to the acceleration of the object (as stated in the second law). If the object accelerates then the force accelerates, if the acceleration decreases then the force decreases. Same for mass. The force of the car would have changed from 315 newtons of force to 1,260 newtons of force.
One plate goes under another in the subduction zone. So for
the given question, the correct option is option “A”. Subduction rates are not
very high. They can be only a few centimeters per year and that is the reason
people do not feel the effect. The plates between which the shifting occurs can
either be oceanic crust or the continental crust. Mountain formations are
necessarily associated with subduction movements of plates. In such cases the
movements are huge and can result in earth quakes as well.
i don't know what symbol ya'll use for wavelength so i just put the word instead.We use the greek symbol lambda.So just plug in everything you know.
wavelength=4.257×10^-7x10^-2 and
v=speed of light = 3×10^8
So you should get f= 7.04 ×10^15Hz
