The wind-chill index is modeled by the function w = 13.12 + 0.6215t − 11.37v0.16 + 0.3965tv0.16 where t is the temperature (°c) and v is the wind speed (km/h). when t = 2°c and v = 32 km/h, by how much would you expect the apparent temperature w to drop if the actual temperature decreases by 1°c? (round your answers to two decimal places.)

answer: a. same unit

explanation:

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
