Replaces spring 2. the mass of the weight and pulley are unchanged: m=5.8 kg and mp=1.7 kg
Answer
given,
angle between two polarizing filters = 45°
filter reduce intensity = ?
a) I = I₀ Cos² θ
here θ = 45⁰
intensity of the light is reduced by 0.500
correct answer from the given option D
b) direction of the polarization
θ = 45°
Answer: I would say the object with the Lower velocity because Lighter with Higher velocity makes it heavy, velocity is how heavy something is so the lighter it is the less difficult it will be to catch.
it's called elastic potential energy
What do you mean when you say "this" graph ? I don't see any graph.
First of all, I'm sure you don't have a "velocity versus time" graph.
You may have a "speed versus time" graph, that doesn't show any
information about the direction of the motion.
As you look at your graph ... a feat that's impossible for me ...
-- If the line is horizontal, then speed is not changing. If the direction
of motion is also not changing, then there is zero acceleration. Sadly,
the graph most likely doesn't carry any information about the direction.
It's possible that the speed is constant but the direction is changing.
Then acceleration isn't zero, but you can't tell that from the graph.
-- If the line is proceeding upward from left to right, whether it's straight
or curving, then there is positive acceleration.
-- If the line is proceeding downward from left to right, whether it's straight
or curving, then there is negative acceleration, or what some people might
call "positive deceleration".
