PLEASE HELP IVE BEEN TRYING THIS OUT THE PAST HOUR: The angle phase represents the phase shift, determined by the initial conditions of the experiment or the position of the weight at t = 0. If the weight is at its maximum positive position (weight is above equilibrium) at t = 0, then phase = 0. If the weight is at its maximum negative position (spring is stretched and weight is below equilibrium) at t = 0, then phase=pi. If the weight is traveling in the negative direction and passing through equilibrium at t = 0, then phase= pi/2. Please describe the initial condition of our experiment; specifically, describe the position of the weight and the direction in which it was traveling.

The measurement of one angle of a right triangle is 42° what is the measurement of the third angle? (there is no picture)

Nthe opening scene of the movie raiders of the lost ark, indiana jones replaces a golden statue with a bag of sand. the platform on which the statue is placed is designed to detect the mass of the statue. if the bag of sand has a different mass than the statue, then a mechanism triggers and destruction ensues. the density of gold is about 20\text{ g/cm}^320 g/cm 3 20, space, g, slash, c, m, start superscript, 3, end superscript. the density of sand can be estimated at 2.5\text{ g/cm}^32.5 g/cm 3 2, point, 5, space, g, slash, c, m, start superscript, 3, end superscript. the gold statue can be modeled as a cylinder with height 25\text{ cm}25 cm25, space, c, m and radius 8\text{ cm}8 cm8, space, c, m. in terms of \piπpi, what is the mass of sand indiana jones needs to avoid triggering the mechanism?
