Gravity as all bodies whether large or small have mass.
Do you know what lesson this is ? i can probably help
Answer:
Fracturing can emit seismic waves through the ground.
Explanation:
I believe the answer is seismic, I've studied this before.
Diceplacement is the distance an object has traveled in a certain direction
for example, if you were to walk North for 20m, then east for 40m, the <u>distance</u> you have traveled is 60m however your displacement is the distance between your starting position and your end position;
sqrt(20^2+40^2) = 44.7m
and because displacement is a vector, there needs to be a direction;
sin(theta)=40/44.7
theta=63.4 degrees East of North
therefore the true displacement is 44.7m at 63.4 degrees East of North
The effect that is seen is that the brightness of the bulb is unaffected by switching the polarity of the magnet; however, the order in which the needle deflects on the voltmeter is flipped when you do so.
This is further explained below.
<h3>What is switching the polarity?</h3>
Generally, When the polarity is reversed, both the hot wire and the neutral wire are switched, which causes the electric current to flow in the opposite direction. Because of this, the electric current enters the appliance through the neutral terminal rather than the hot terminal, which energizes the appliance even when it is turned off.
In a worst-case scenario, the battery's shell might burst apart due to the heat generated by the polarity reversal, which would release hydrogen gas, which is flammable. Acid from the battery may leak out of the box and burn you or damage your expensive electronics.
In conclusion, In this case, reversing the magnet's polarity has no impact on the light output of the bulb, but it does reverse the direction of the voltmeter's needle deflection.
