Homosapiens I think? I’m not sure but I’m 30% sure
<span>The amount of heat energy needed to increase the temperature of a substance by </span>
<span> is given by:
</span>
<span>
where m is the mass of the substance, Cs is its specific heat capacity and </span>
<span> is the increase in temperature of the substance.
In this problem, we have a certain mass m of gold, with specific heat capacity </span>
<span>, to which we add Q=2825 J of energy. Its temperature increases by </span>
<span>. Therefore, if we re-arrange the previous equation, we can find the mass of the block of gold:
</span>
<span>
So, the correct answer is B.</span>
Well let's analyse.
First we know Ohm's law of resistance that states:
Where R is resistance, U is voltage and I is current.
If we express current we get:
Because resistance cannot be equal to 0 (violation of mathematical law) the only thing that may cause current being zero is voltage.
Which means that as long as your voltage is bigger than 0V then there will be current (if we are talking about AC).
So to answer the question: Electric current is caused by voltage and regulated by resistance.
Hope this helps.

Answer:
285.7s
Explanation:
Given parameters:
Speed of the person = 1.4m/s
Unknown:
Time it takes to walk one time round the track = ?
Solution:
The circumference of the track is 400m for a standard pitch.
Now;
Speed =
Time =
Now insert the parameters;
Time = = 285.7s
Particle arrangement and movement
⇒ In terms of relative energy, gas particles have the most energy, solid particles have the least energy and liquid particles are somewhere in between. (All compared at the same temperature.)
