PLEASE HELP: A person stands 6.00 m from a
speaker, and 8.00 m from an
identical speaker. What is the
wavelength of the first (n=1)
interference maximum
(constructive)?
(Speed of sound = 343 m/s)
(Unit = m)

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

in this image, you can see solar radiation going through ocean water.

no image, but probably absorption

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
