What is sound
energy?
vibrations that move the tiny bones in the ear
O
energy that moves things
energy of moving electrons
energy carried by light

I’ll give u thingy if u answer pl

i think that the one about vibrations is the one, because mechanical energy is energy that moves things, energy of moving electrons is electrical energy, and light definitely doesn't have to do with sound. I'm not quite sure tho because none of these definitions are that good :/

compass can be used day and night, cloudy or sunny

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
