When two tectonic plates collide, new mountain ranges can be formed as rock in the Earth’s crust is thrust upward. Usually this action involves one plate being pushed underneath another plate as shown in the diagram below. Which of Newton’s Laws best describes why the edge of the right-hand plate forms mountains while the left-hand plate is submerged beneath the right in the picture?

Law of Inertia (1st Law)
Law of Acceleration (2nd Law)
Action-Reaction Law (3rd Law)
Law of Universal Gravitation (4th Law)

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

okay i have so many questions. but the big one here is: um wt..f is this mess? ?

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
