Lab Activity Interact with the virtual laboratory to create an electromagnet to pick up paperclips.
Notice that there are many variables to test in this lab:
different types of material,
• different gauges or thicknesses of wire,
• number of winds around the iron bar,
the voltage
.
.
→ Open the lab interactive and run a few trials changing the variables each time. Decide|
which variable you want to change in order to make a strong electromagnet and record it
here.
Hypothesis (5 points)
Record your hypothesis as an "if, then" statement.
(If the independent variable does this, then the dependent variable will do that)

If the wheels lock when braking suddenly the vehicle: a: loses traction b: lose steering wheel ability c: gain speed slightly d: gain steering ability

If a star is moving toward earth, it is

The dipole moment of the water molecule (h2o) is 6.17x10^-30 c. m. consider a water molecule located at the origin whose dipole moment p points in the +x-direction. a chlorine ion ( of charge-1.60x10^-19c , is located at x=3.00x10^-9m . assume that is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. a) find the magnitude of the electric force that the water molecule exerts on the chlorine ion. b) what is the direction of the electric force. -x-direction or +x-direction c) is this force attractive or repulsive?
