Two large speakers broadcast the sound of a band tuning up before an outdoor concert. While the band plays an A whose wavelength is 0.773 m,
Brenda walks to the refreshment stand along a line parallel to the speakers. If
the speakers are separated by 12.0 m and Brenda is 24.0 m away, how far
must she walk between the "loudspots"?

What are chlorofluorocarbons and what impact do they have on the atmosphere?

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass

Which of the following correctly describes what happens when an atomic bomb explodes? small pieces of fissionable material are joined and form a body with a mass greater than the critical mass, the relative number of neutrons escaping decreases, and a chain reaction and explosion result. large pieces of fissionable matter are brought together quickly and form a body with a mass smaller than the critical mass, the relative number of escaping neutrons increases, and a chain reaction and explosion result.
