Answer:
Explanation:
The spaceship has traveled 3% of the distance to a space station and it has traveled miles.
Let the total distance from the ship's starting point to the space station be x.
This means that:
The total distance to be traveled is .
Therefore, the distance left to travel is:
<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>
</span>
where m is the mass of the substance, Cs is its specific heat capacity and </span>
In this problem, we have a certain mass m of gold, with specific heat capacity </span>
</span>
So, the correct answer is B.</span>
