Question 1 2 pts Graphed below is the displacement of an object undergoing simple harmonic motion. The amplitude of the oscillation is 2cm and the period is 5s. You'll note that there are no values listed on the axes for the graph. What is the spacing for the tick marks on the horizontal axis? [ Select ] What is the spacing for the tick marks on the vertical axis? [ Select ] V Question 2 1 pts Electricity in the US is AC, meaning the electrical voltage oscillates. In most homes, the voltage coming out of a wall outlet has a period of 0.0167s and its amplitude is 170V. What is the equation for the oscillating voltage, V(t)? In these equations, assume the phase is zero. Units have been left out for simplicity O V(t) = 170 cos( 376 t) O V(t) = 0.0167 cos( 0.037 t) O V(t) = 0.0167 cos( 170 t ) O V(t) = 0.0167 cos( 1070 t ) O V(t) = 170 cos( 0.0167 t) O V(t) = 170 cos( 1.05 t)
