James had a fixation on how to best preserve fresh cut flowers. He tried various methods: adding bleach to the water, using filt

ered water, adding an aspirin tablet to the water, using a combination of sugar and water, using cold water, and using hot water. Over the course of his study, he came to the conclusion that while bleach changed the color of the plant, it did allow for the plant to last longer than the other changes. Based on this study, the dependent variable is: 1. Type of plant 2. Life of the cut plant 3. Color of the plant 4. Changes to the water

Two identical small charged spheres are a certain distance apart, and each one initially experiences an electrostatic force of m
monitta

Answer:

1/4F

Explanation:

We already know thatThe electrostatic force is directly proportional to the product of the charge, from Coulomb's law.

So F α Qq

But if it is now half the initial charges, then

F α (1/2)Q *(1/2)q

F α (1/4)Qq

Thus the resultant charges are each halved is (1/4) and the first initial force experienced at full charge.

Thus the answer will be 1/4F

Select the correct location on the image.<br> Identify the magnetic north pole of Earth’s magnet.
OverLord2011 [107]

The magnetic north pole of the earth's magnet is in the geographic south pole.

  • There are two magnetic and geographic poles each, north and south
  • The two geographic poles are the locations where the earth's axis of rotation passes through which is imaginary
  • The magnetic north and south poles are not the same as the geographic north and south poles
  • In a compass, the needle points to the magnetic north pole
  • By convention, the magnetic north pole corresponds to the geographic south pole
  • The magnetic south pole corresponds to the geographic north pole
  • The magnetic field lines of a magnet start from the magnetic north pole and end at the magnetic south pole

The magnetic north pole of the earth's magnet is the geographic south pole.
