Conceptual - mass, period, spring constantconsider a simple harmonic oscillator made of a mass sliding on africtionless surface, and attached to a massless linear spring. which of the following statements are true/false? a. truefalse doubling the mass will halve the period. b. truefalse doubling the amplitude will not change the frequency. c. truefalse doubling the spring constant will double thefrequency. d. truefalse tripling the mass will sextuple the period. e. truefalse halving the amplitude will quadruple the period.

Suppose you have a box. which of these is not necessarily a true statement regarding the relationship between the force applied to the box, the work done on the box, and the distance the box is moved? a. if the box is not moved, no force is being applied to the box. b. if no force is applied to the box, no work is done on the box. c. if work is done on the box, then a force is applied to the box. d. if work is done on the box, then the box is moved a distance.

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".

If the specific heat of a metal is 0.850 j/g °c, what is its atomic weight?
