Are you the opposite charge?
Because I'm attracted yo you
You apply a force on an electron to push it towards a negatively charged plate. Are you doing positive or negative work on the electron.
B) is it gaining or losing potential energy
Positive work
Gaining potential
Why does time flow in one direction?
2nd law of thermodynamics/ entropy
1% of your weight is mass, the other 99% is ?
Energy (potential)
What are the school colours?
Navy and Cyrese
Are you a photon?

It is the same
A 1000kg car travelling at 30m/s crashes into a stationary bike that weighs 60kg (the collision lasts 0.3 seconds). The car has final velocity of 20m/s in the same direction.
a) Which experiences the greater force?
b) Determine the acceleration the bike experiences during the collision
a) Equal force
B) Find Force on Bike: a=30m/s2 m=1000kg; F=30,000N
Acceleration on bike: 30,000N/60
a= 500 m/s2
The merivale campus of Brisbane state high was once a ______ that students could practice on.
Farm
In what year did students light flares in F Block and the police were called to investigate since world leaders were at Southbank for the G20 Summit?
2011
Are we going through a phase change?
Because I can sense an increase in potential
You are travelling at the speed of light in a spaceship, and you throw a ball forward at 1/2 the speed of light (you're very strong). What is the speed of the ball compared to someone standing by and watching?
The speed of light (nothing can travel faster)
Also, the question is broken because you with mass can't reach that speed and would not perceive time at the speed of light either
A 3kg ball is dropped from a height of 10m. Halfway down the fall its velocity is 7m/s. Determine the force of air resistance on the ball.
Half way = 147J this should give a velocity of 9.89m/s.
Actual velocity is 7m/s which gives 73.5J of KE.
Change in energy = 147J-73.5J =73.5 J of work done by air
W=FS
73.5/5 = 14.7N
"I ran like the wind" is an example of what type of poetic device?
Simile
What is the gate code?
" I Don't Know"
What is your gravitational field strength?
Because I'm falling for you
Who experiences a greater force, person A who weighs 70kg moving 30m/s to the left, or a truck weighing 1000kg moving at 4m/s to the right? Justify mathematically.
Neither, they both experience 0N
You accelerate from 3m/s to 8m/s in 10 seconds. Determine the acceleration over this time.
0.5 m/s2
