Answer:

Step-by-step explanation:

Hi there!

At first glance, this question may look tricky, but don’t overthink it!

The question states that he has more than 20 coins.

Answer A states that he has exactly 20 coins, which can’t be right because he has more than that!

Answer B states he has less than 20 coins, which isn’t right either.

Answer D is his actual amount of coins plus 20, which can’t be applied here

Answer C states that he has more than 20 coins, so that’s your answer!

I hope this helps! :)

If you had carried out the algebra using variables before plugging numbers into your expressions, you would have found that (vf)

SashulF [63]

Answer:

Step-by-step explanation:

Volt is energy per electric charge

$1V=1J/C$

and the energy units in terms of meters, seconds and kilograms are:

$1J= 1kg\frac{m^{2}}{s^{2}}$

So the unit of volt is

$1V= kg \frac{m^{2}}{Cs^{2}}$

So the velocity expression (it can not be read completly) but i guess that it could be as follows

$vf_{a} = -2\sqrt{\frac{q_{a}\Delta V}{m_{a}}}$

So the unit analysis would be

$vf_{a} = \sqrt{\frac{C kg\frac{m^{2}}{Cs^{2}}}{kg}}}$

note that the coulomb unit of numerator is cancelled from the denominator. The same occurs for kg unit.

$vf_{a} = \sqrt{\frac{m^{2}}{s^{2}}}$

Applying square root

$vf_{a} = \frac{m}{s}$
