A physics lecture room has a volume of 263 m3:

A) For a pressure of 1.00 atm and a temperature of 24.0 ∘C, use the ideal-gas law to estimate the number of air molecules in the room. Assume all the air is N2
B) Calculate the particle density-that is, the number of N2 molecules per cubic centimeter.
C) Calculate the mass of the air in the room.

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude

Waves are used in many practical applications to support work, entertainment, and health. one example is the use of ultrasound imaging to safely track the development of a growing fetus. what is a specific example of a practical application of waves in medicine, entertainment, safety, or other fields? provide a brief explanation of how the properties of waves are useful to that application.
