5. A perfect vacuum is __ A. 0 psi B. 0 psig C. 14.7 psia D. 29.92 in . Hg

1. Choose the correct statement or equation. When a wave in a string reflects from an open or flexible end, the reflected wave has the same wavelength and amplitude as the original wave. When a wave in a string reflects from a fixed end, the reflected wave has the same wavelength and amplitude as the original wave.

Asample has a mass of 2.5 kg When the sample is suspended from the lower end of astring and totally immersed in water, the tension in the string is 11.2 N. What is the smallest density of a liquid in which the sample will float? Remember that $\rho _{water}=997kg/m^{3}$ $1838kg/m^{3}$ $1835kg/m^{3}$ $1828kg/m^{3}$ $1849kg/m^{3}$

In what ways are meteorites different from meteors? What is the probable origin of each? Meteors typically come from comets that have passed through the solar system; their solid material is freed when the ice is vaporized by the heat of the Sun. Meteorites miss the atmosphere whereas meteors hit the outer layers only. Most meteors come from Mars and carry important information about the past of the red planet. Meteorites are large enough to withstand the violent passage through Earth's atmosphere, whereas meteors burn up from the heat of friction. Most meteorites, on the other hand, are from asteroids or from debris kicked up on the Moon or Mars during an impact.

If a rock is dropped from a height of 87 ft, its poistion t seconds after it is dropped until it hits the ground is given by the function $s(t)=-16t^{2}+87$ Round values below to 3 decimal places. How long does it take the rock to hit the ground? $\square $ seconds Find the average velocity of the rock from when it is released until when it hits the ground. $\square $ feet per second What time after the rock is thrown will its instantaneous velocity be equal to its average velocity? (Apply the Mean Value Theorem) $\square $ seconds after it is thrown

The bending or change in angle of light as it passes through a lens is called $\square $

Photons of a certain infrared light have an energy of $1.91\times 10^{-19}J$ (a) What is the frequency of this IR light? $\square $ Hz (b) Use $\lambda =c/f$ to calculate its wavelength in nanometers. $\square $ nm

The outer planets of the solar system were formed by asteroid agglomeration comet collisions gravitational forces temperature increases
