An airplane is flying over the South Pole. Which arrow correctly shows the direction gravity pulls the plane? Airplane underneath Earth with four arrows around it. An arrow is pointing from the top of the plane towards space labeled one. An arrow behind the plane pointing away from the plane labeled two, an arrow below the plane pointing towards Earth labeled three, and an arrow in front of the plan pointing in the direction of the motion of the plane labeled four.

What type of light does this light bulb produce most (i. e. at what wavelength does the spectrum have maximum intensity)?

The law of conservation of energy states that energy cannot be created or , energy can be from one substance to another. the first blank is ' destroyed ' and for the second blank is ' transferred '

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
