String lights give off energy such as heat and light when plugged in. Think about how the energy in the string lights is related to the electromagnetic spectrum.

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm

Akg a of 55 m at an of 11 ? . if is at 98 km/h,be ?
