A bottlenose dolphin lives in warm water near the equator and a beluga whale lives in cold water near the Arctic circle. Both animals use echolocation to communicate and hunt for prey. Based on what you know about sound, which animal would be able to use its echolocation better to gather information about its surroundings?

momentum of soft ball three times less than baskey ball

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

moisture is lackin, and organic acids are scarce.

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
