Answer:
A principle stating that energy cannot be created or destroyed, but can be altered from one form to another.
Explanation:
Answer:
speeds up, turns a corner at constant speed, and slows down.
Explanation:
Acceleration occurs anytime an object's speed increases or decreases, or it changes direction.
The force of attraction / repultion of two charges is given by F = KQ1Q2 / d^2; where K is the Coulumbs constant, Q1 is the charge on charge 1, Q2 is the charge on charge 2, d is the distance of the two chardes apart.
Thus,
KQ1Q2 / 4 = 2 x 10^-5
KQ1Q2 = 4 x 2 x 10^-5 = 8 x 10^-5
When the distance between the charges was reduced to 1 meter.
F = KQ1Q2 / d^2 = 8 x 10^-5 / 1^2 = 8 x 10^-5
Therefore, option C is the correct answer.
Answer:
If it points the other way, the fields subtract, for a lower energy, and so the magnet prefers to turn to point in this way. Magnets in uniform fields feel torques which make them turn around if they are not pointing in the right direction, but there is no net force making the magnet want to levitate.
Explanation:
Answer:
A
Explanation:
To measure wavelength, you would find the distance from crest (top of the wave) to crest.
Hope this helps! :)
