Answer:
The magnitude of the net electric field inside the solution is 3.704 N/C
Explanation:
Given;
average drift speed, v = 3 x 10⁻⁷ m/s
mobility of the bromide ions, μ = 8.1 x 10⁻⁸ (m/s)(N/C)
The magnitude of the net electric field inside the solution is given by the equation below;
where;
E is the magnitude of the net electric field inside the solution
Substitute the given values and solve for E
Therefore, the magnitude of the net electric field inside the solution is 3.704 N/C
Answer: Picture (d) is the correct answer.
Explanation:
When liquid nitrogen is at -320 degrees then as the temperature is very low, therefore, molecules of nitrogen will be much closer to each other.
Whereas when liquid nitrogen is boiled then we are increasing the temperature. As a result, force of attraction between the molecules decreases and they will move far apart from each other.
It is known that below 63 K liquid nitrogen tends to freeze and thus it becomes solid. So, at -320 degrees liquid nitrogen will be in solid state.
In the given pictures, picture (d) represents the change caused by adding heat to liquid nitrogen.
Answer:
it will travel 69 m long consuming. it is totally wrong
The ball's vertical position 
in the air at time 
is
The ball is at its original height when 
, which happens at
Meanwhile, the ball's horizontal position 
at time is
So when the ball reaches its original height a second time, the ball will have traveled a horizontal distance of
(which you might recognize as the formula for the range of a projectile)
To reach a distance of 
, the initial speed 
would be
The isotopes contribute to the average atomic mass based on their abundance. The result is that the "average" mass for the atoms of an element is dictated by the most abundant or common isotope. The average atomic mass for carbon is 12.0107 amu.
The atomic mass as displayed on the periodic table is a weighted average relative atomic mass of the naturally occuring isotopes of that element.
An isotope is an element with the same number of protons but a different number of neutrons
For example - Carbon naturally occurs in isotopes C12, C13 and C14 with abundances of 98.9% 1.1% and 'trace' respectively.
the average mass is then calculated by 12*98.9%+13*1.1% = 12.01g/mol
