When Santa arrived in Texas on Christmas eve, it was cold and snowy and the roofs were very icy. Santa landed his sleigh and stepped out onto the icy roof. As Santa's foot pushed backward, an equal
and opposite force pushed the sleigh forward on the icy surface. Luckily, Rudolph and Dancer kept
the sleigh from sliding off the roof!

Is this the Law of Inertia (1st), Law of Acceleration (2nd) or Law of Action/Reaction (3rd)?

Explain
your reasoning.

Atomic nuclei of almost all elements consist of

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.

Which of these statements best explains how the hydrosphere interacts with the atmosphere to affect global climate? mountains block rain clouds and cause changes in global rainfall and evaporation. humans burn fossil fuels to produce greenhouse gases which cause global warming. humans cut down trees which affects the amount of oxygen in different parts of the globe. greenhouse gases, like carbon dioxide, dissolve in oceans and prevent global warming.
