Properties that define the light is a wave are
1. Speed : speed of light is 300,000 Km /s, It is most fundamenta property of light to define light is a wave
2. Reflection: Light particles or photons reflect off the particles or masses are continue to travel at the same speed.
3. colour
B) It’s material moves due to convection currents.
Work = Force * distance
He's going up an incline but pushing parallel to the ground. Draw out a diagram to show what's going on. )
Work = force* distance*Cos(incline angle)
60 N force * 10 meters * cos(30)
= 519.61 J
U hi why exactly are you trying to do
Answer:
35 m/s^2
Explanation:
Decceleration = change in velocity / change in time
= ( 70 m/s ) / 2 seconds = 35 m/s^2
DEcceleration = 35 m/s^2
Jason's speed changes by - 35 m/s^2
