Answer:
Explanation:
Given a material with temperature coefficient of resistance <em>c</em>, the equation that relates the resistance at temperature and the resistance at temperature is
We want to double our resistance, so , thus having:
For this T must be:
which for our values means (with , remember to write temperature in S.I., and that for silver ):
In the first law of thermodynamics, the Q stands for heat.
delta E is the change in internal energy of a closed system is equal to the amount of heat (Q) in the system minus the amount of work done (W).

Explanation:
5 mins
Explanation:
because speed ÷ to distance since the distance is 5 miles the answer is 5mins if not it's 0.2 if the teacher incorrect it
Answer:
The value is
Explanation:
Generally the relative speed at which you are moving with respect to the person ahead of you is mathematically represented as
substituting 1.05 m/s for and 2.75 m/s for
So
=>
Generally the distance by which the person is ahead of you is mathematically represented as
substituting 18.5 s for
=>
