Answer:
It would be hard to make a model that shows the real sizes and distances between planets ( B )
Explanation:
Yuri building a model of the solar system will face the difficult of replicating the correct distances between the planets and the real sizes of the planets, because in model building the key factors of the Model must be represented properly.
The size of the planets and the distance between the planets are key factors when trying to model the solar system. but the distance between the planets depends on the position of the planets on their orbits which means the distances are not constant ( fixed ) hence that would be the limitation of his model.
Two dangerous elements can form a compound that is edible known as "NaCl salt".
<u>Explanation:</u>
Sodium and chlorine are two very dangerous elements. As the reaction between sodium and water is extremely violent and chlorine is a very toxic gas. But combination of these elements result into a harmless product with unique properties like it is edible and dissolves without exploding in water.
In sodium chloride reaction the atoms of sodium interact with chlorine atoms. Sodium will donate an electron (by becoming positively charged) to acceptor chlorine (which become negatively charged) as given in following reaction
As sodium and chlorine are very keen to achieve noble gas configuration by completing an octet on donating and accepting an electron respectively.
Answer:
The answer is 2X as much illumination as connection in series
Explanation:
We are given from the question that the two bulbs are identical in power and resistance.
Firstly we know that In a series connection the Voltage across the circuit elements are different whereas In a parallel connection, the same value of voltage passes through all the circuit elements.
Power is expressed as ;
P = V^2/ R
An increase in voltage leads to an increase in power likewise if the voltage is reduced the power also reduces.
The two bulbs are said to be having the same resistances , so the voltage across them in a series connection will be halved
V =1/2V1 + 1/2 V2; making the illumination across them to be low.
Therefore in parallel the illumination will be twice as much the illumination when connected in series.
Answer:
Explanation:
Given data:
Mass of the paper clip, 
Kinetic energy, 
Let the velocity of the paper clip when it is thrown be <em>v</em>.
Thus,
(rounding to nearest tenth)
