Answer: B 2V
Explanation:
Since the voltage of the battery is 2V.
At point A and B, there is no voltage drop. So the voltage will still be same as in the battery which is 2V.
The heat capacity is given by the expression:
When the is measured in the calorimeter, we obtain a value, and since we know the mass of the material and we control the change in , we can then determine the specific heat "C" by simply remplazing in the expression.
Answer:
It will have an acceleration of .
Explanation:
Newton’s second law is defined as:
(1)
Equation 1 can be rewritten for the case of the acceleration:
The force and the acceleration are directly proportional (if one increase the other will increase too).
But 1 N is equivalent to
So a body will have an acceleration as a consequence of the action of a force.
To find the acceleration of the car, we can use the equation acelleration=final velocity-initial velocity/elapsed time. Since we know the initial velocity is zero from the start, than we can calculate it as final velocity/elapsed time. If we divide 36 by 10, we get 3.6. Your acceleration is 3.6 km/h.
Hope this helps! :D
