D.) 5kg
This is a trick question. The mass of an object does not change based in location. However the weight of an object does change, this is because Weight = Mass × Gravity. Also mass is measured in kilograms and so the answer is 5 kg. So if you ever want to lose weight just go to the moon!
Answer:
2. a region about the nucleus in which an electron of specified energy will probably be found
Explanation:
With quantum mechanics we can find the wave function that describes the movement of the particles, the interpretation of this wave function is through the probability density (φ* φ).
This probabilistic interpretation of the energies, position and amounts of motion electrons allow us to find the region around the nucleus where an electron of specific energy can be found with a given probability.
The correct answer is 2
Answer:
<em>v=u + at</em>
<em>0= 22 + a*2</em>
<em>a = -22/2 = -11 m/s^2</em>
<em>The car's acceleration is -11 m/s^2</em>
<em>V^2 = u^2 + 2as</em>
<em>022^2 + 2*(-11)</em><em>s</em>
<em>s = 22^2/22 = 22m</em>
<em> </em><em>The car will travel 22 m before stopping.</em>

The leaves of a negatively charged electroscope will move apart if a positively charged rod is brought close to the top of the electroscope, but not touching it.
What is an electroscope?
An early scientific tool used to find an electrical charge on a body is called an electroscope. The movement of a test object caused by the Coulomb electrostatic force is used to detect charge. An object's charge is inversely proportional to its voltage.
part a) leaves will repel. leaves will move further apart.
part b) all the negative moves to the top to get closer to the positive leaves go back together as an excess negative move to the top. leaves separate less.
