An auditorium measures 43.0m × 18.0m × 15.0m. the density of air is 1.20 kg/m3. what is the volume of the room in cubic feet? (do not input units. note that 1m = 3.28ft)
my answer 43x18x15 = 11,610 m^3 11,610m3 * 3.28ft m = 38,080.8 ft when i used this number i got it incorrect and it said for me to use less figures

In which scenario is the least amount of work done on a crate? a force of 120 n moves it 25 m. a force of 115 n moves it 26 m. a force of 130 n moves it 22 m. a force of 125 n moves it 27 m.

A-4.60 μc charge is moving at a constant speed of 6.80×105 m/s in the +x−direction relative to a reference frame. at the instant when the point charge is at the origin, what is the magnetic-field vector it produces at the following points.

Astudent is given an assignment to demonstrate diffraction. he takes a photograph of a straw in a glass of water. the straw appears bent at the water level. which best describes this example? a) this is a good example of diffraction. b) this is an example of dispersion and not diffraction. c) this is an example of refraction and not diffraction. d) this is an example of reflection and not diffraction.
