PLS HELP PLS Awhina is constructing an electromagnet to demonstrate at the upcoming science fair. She is using wire, a nail, and a battery.

How would this electromagnet work?

An ideal polarizer with its transmission axis rotated 30 degrees to the vertical is placed in a beam of unpolarized light of intensity 10w/m^2. after passing through the polarizer, what is the intensity of the beam? a. 8.7 w/m^2 b. 7.5 w/m^2 c. 5.0 w/m^2 d. 10 w/m^2 e. 2.5 w/m^2

For this car, predict the shape of a graph that shows distance (x) versus time (t). note that time is the independent variable and will be on the bottom axis. need asap

If forces acting on an object are unbalanced. true or false
