Answer:
0.5I0
Explanation:
Because once ligh passes though any polarizer 50% of it is gone. The second polarizer is also oriented in the same direction so it passes through with no effect.
Answer:
Ball 1 has a mass of 0.5 kilogram and an initial velocity of 1.00 meter/second. Ball 2 has a mass of 1.5 kg and an initial velocity of 0.00 meters/second.
Explanation:
A) Starting from rest, we have the entire cycle determined by 0.8s.
If we assume a constant movement, half of that time is when it reaches the highest point, that is, in 0.4s.
The distance as a function of speed and acceleration is given by,
At the initial point the speed is zero and the acceleration is equivalent to gravity.
B) When returning to the ground, the final speed is zero. Therefore, the equation that relates velocity to acceleration is given by,
Answer: B
Explanation: Your nerves send messages to different parts of your body in order to function and feel certain things

Hi, this sounds like a chemistry question:
If you wanted to separate sand from iron fillings for example, using tweezers would be a great tool to do this, depending on the size of the iron fillings.
