In Physics terms, what is the difference between "speed" and "velocity"? (it is the same thing that differentiates "distance" from "displacement")

Plzz plzzz i'll give you 25 pointshow does the water cycle influence weather in your area? use complete sentences and a specific example from your experience.

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2. how much is the spring compressed x from its natural length? 1) x = v0*sqrt(k/(mg)) 2) x=v0*sqrt(m/k) 3) x=v0*((mk)/g) 4) x=v0*sqrt(k/m) 5) x=v0*(m/kg) 6) x=v0*sqrt((mg)/k) 7) x=(v0)^2/(2g) 8) x=v0*(k/(mg)) 9) x=(v0)^2/(2m) 10) x=v0*((mg)/k)

Notice how they put future which of the clouds shown would indicate a possible future rain storm? a) b) c) d)
