I forgot how to do this ;;;

Explanation:

Acceleration is change in velocity over change in time.

a = Δv / Δt

a = (10 m/s − 5 m/s) / 4 s

a = 1.25 m/s²

Work = force × distance

First, find the distance traveled.

v² = v₀² + 2aΔx

(10 m/s)² = (5 m/s)² + 2 (1.25 m/s²) Δx

Δx = 30 m

Now find the work:

W = (600 kg × 1.25 m/s²) (30 m)

W = 22,500 J

Alternative, work = change in energy.

W = ΔKE

W = ½ mv² − ½ mv₀²

W = ½ m (v² − v₀²)

W = ½ (600 kg) ((10 m/s)² − (5 m/s)²)

W = 22,500 J

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
