Answer:
Grounding a Positively Charged Object
Electrons were transferred from the electroscope to the ground. As in the case of grounding a negatively charged electroscope, the grounding of a positively charged electroscope involves charge sharing. The excess positive charge is shared between the electroscope and the ground.
Explanation:
Answer:
B
Explanation:
When something is moving at a constant velocity it's called the centripetal force. And the centripetal force accelerates radially outwards. It's like an ambulance siren. the sound waves are being exerted out into the atmosphere radiallly.
Salt is a compound, with the chemical name "Sodium chloride"
and the chemical formula NaCl.
Each molecule of salt is an atom of sodium electrically bound to
an atom of chlorine.
The chemical properties of salt are completely different from the
chemical properties of either element in its molecule. In fact,
sodium and chlorine are both toxic and corrosive, i.e., poison,
but as long as the salt is still salt, you can safely eat it !
There's nothing physical or mechanical, like spinning or filtering,
that you can do to salt to separate the sodium from the chlorine.
That takes electrical or chemical processes, and once you separate
them, you wind up with two substances that are both dangerous.
If you put salt into a jar with some sand and shake it up, then you
have a mixture. The salt is still salt and the sand is still sand, and
they can be separated quite easily.
If you put some salt in some water, and stir it up so that the salt
dissolves, then you have a salt solution. Some of the salt
molecules actually come apart in it, and there are sodium ions
and chlorine ions in the water. When that happens, the water
begins to conduct electric current very nicely, and if you DO
pass current through it, you get sodium collecting at the end
of one wire, and chlorine collecting at the other wire. But if you
just let it set there in the sun, or heat the solution on the stove,
then once the water evaporates, you have plain old salt again
in the jar.
Answer:
The object will sink in the liquid in beaker 1.
The object will float in the liquid in beaker 2
Explanation:
The density of an object relative to the density of a fluid determines if the object floats or sink in a fluid. The density of a material is the measure of the amount of mass of that material packed into a unit volume of that material.
For the beaker 1, the liquid in this beaker has a density of 0.5 g/cc, which is lesser than the density of the object (0.85 g/cc). This means that the object will add more mass than there should be to the volume of the space it displaces within the field. This results in the object sinking in the fluid.
For beaker 2, the liquid in this beaker has a density of 1 g/cc, which is more than the density of the object (0.85 g/cc). This means that the object will add less mass than there should be to the volume of the space it displaces within the field. This results in the object floating in the fluid.
Answer:
the 5 is because u have to select the currents and volts which gives us 2 and 1 plus 3 is 6 but if we rest 1 is 5, thats the answer
