Melting, of course. Just as how an ice cube melts to water.
Answer:
Explanation:
The magnitude of the electrical force between the two point charges is
where
k is the Coulomb's constant
is the magnitude of each charge
r = 3.00 m is the separation between the two charges
Substituting the numbers into the formula, we find
Answer:
Explanation:
The acceleration of an object is the rate of change of velocity of an object.
Mathematically, it is given by:
where
is the change in velocity
is the change in time
In this problem, we have a graph of the speed (which is equal to the velocity, since the motion is in a straight line) versus the time. Therefore, the slope of the graph is exactly equal to the acceleration of the object:
So, we can find the magnitude of the acceleration of the car by evaluating the slope of this line.
Taking the last point (12.0 s, 15.0 m/s) and the starting point (0 s, 0 m/s), we have:
So, the acceleration is:
