Answer:
Explanation:
From the information given:
The motional emf can be computed by using the formula:
E = 0.72 volts
According to the question, suppose the wire segment was parallel, there will no be any emf induced since the magnetic field is present along the y-axis.
As such, for any motional emf should be induced, the magnetic field, length, and velocity are required to be perpendicular to one another .
Then the motional emf will be:
E = 0 (zero)
Answer:
Explanation:
The capacitance of the parallel-plate capacitor is given by:
where
is the vacuum permittivity
is the area of the plates
is the separation between the plates
Substituting,
The energy stored in the capacitor is given by
Since we know the energy
we can re-arrange the formula to find the charge, Q:
1. this is not physics this is anatomy.
2.circulatory system is the flow of blood through the vena cava, right artrium, right ventricle, pulmonary valve, pulmonary ventricle, left atrium, left ventricle, arteries, capillaries, veins vena cava. digestive system is food through the esophagus, stomach, etc. no direct relation.
Hello there!
Plastic is definitely off. Plastic can melt easily in extreme heat, and if it doesn't melt, the chemicals used to create it will seep into the food. D is false.
Aluminum is off too, if we're talking about heating up food in a microwave. Aluminum can spark in the heat and can catch fire/explode in most cases. So that would also be off.
Foam is off as well. Whether it be foam bubbles or foam board, it's probably NOT a good idea to hear up your food in the microwave with foam.
But ceramic would probably be the best choice. Ceramic is microwave safe, it doesn't melt, catch fire, or seep chemicals in the food when placed in that kind of heat. That is probably why a lot of manufacturers use ceramic glass to make plates and bowls in the first place.
So your answer should be B. Ceramic. Hope this helped you! :)
