That depends on the resistance between the ends of the voltage.
<span>To find the rate of speed, simply divide the length of the race by the length of time it took for the horse to run the race. In this case, 2011 m / 121 sec = 16.619 m/sec. Converting this from m/sec to mph, the value becomes approximately 37.1778, or 37.18 mph.</span>
Transformation of energy, because energy cannot be created or destroyed
Answer:
C. How bright it seems to us
Explanation:
Answer:
d = 8 [m]
Explanation:
To solve this problem we must use the principle of conservation of energy, where the mechanical energy in a state plus the work done on the body, must be equal to the mechanical energy in the state Y. This can be easily represented in the following equation.
where:
Ex = Mechanical energy in X [J]
Wx-y = Work among states x and y [J]
Ey = Mechanical energy in Y [J].
The key to being able to understand this problem is that in state X, we only have kinetic energy, while the energy in state Y is equal to zero (there is no movement). The work is equal to the product of force by distance, as work acts in the opposite direction to movement, this has a negative sign.
