Answer:
a
Explanation:
because it has more energy
W, because as time is moving up at a consistent rate the speed is as well, creating the straight line.
Answer:
35.14°C
Explanation:
The equation for linear thermal expansion is , which means that a bar of length with a thermal expansion coefficient under a temperature variation will experiment a length variation .
We have then = 0.481 foot, = 1671 feet and = 0.000013 per centigrade degree (this is just the linear thermal expansion of steel that you must find in a table), which means from the equation for linear thermal expansion that we have a = 22.14°. As said before, these degrees are centigrades (Celsius or Kelvin, it does not matter since it is only a variation), and the foot units cancel on the equation, showing no further conversion was needed.
Since our temperature on a cool spring day was 13.0°C, our new temperature must be = 35.14°C
The answer is C. Electrical;mechanical
