### Subject: Physics (Newtonian Mechanics)

Using Newton’s laws explain why heavier objects require more force than lighter objects to move or accelerate them?

2nd Law Something with more mass moving at the same acceleration as a lighter object would require more force to change its speed or change its direction. Our formula F=m x a is derived from Newton’s second law

### Subject: Mechanical Engineering

how does an easy bake oven work?

The light bulb generates heat through the filament which provides both radiation and convection heating to bake the item. The oven provides insulation maintaining the heat

### Subject: Calculus

True or False. Any value of x that makes the denominator of rational function f equal to zero, represents a vertical asymptote to the graph of f.

False. Not always. Let f(x) = (x + 3) / (x 2 -9). Factor the denominator and simplify to obtain f(x) = 1 / (x - 3) Although x = - 3 makes the denominator equal to 0 there is no vertical asymptote at x = - 3; in fact there is a hole.
