2) If you have a convex mirror with a 3 cm tall object in front of it and the distance between the focal point and the mirror is 12 cm, how far in front of the mirror must the object be in order to
make an image with a height of 1.2 cm?
I
b) Draw a ray tracing diagram of this situation below (label all points in cm):

The image shows a pendulum in simple harmonic motion the pendulum starts at a and swing to e

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)

Is the portion of the electromagnetic spectrum that has a frequency just above that of visible light.
