Calculate the following, and round to the correct number of significant figures: a. (3.1 10^2 cm)x(1.22 10^4 cm)
b. (2.99x10^5km)x(6.88x10^2km)
c. (5.75x10^-5m)/(9.9x10^-2m)
d. (7.83x10^4m)/(3s)

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value

The two most prominent wavelengths in the light emitted by a hydrogen discharge lamp are 656(red) and 486 (blue). light from a hydrogen lamp illuminates a diffraction grating with 500 lines per mm, and the light is observed on a screen 1.50 behind the grating. what is the distance between the first-order red and blue fringes?
