Answer:
continuous change in position with respect to time
Explanation:
Velocity is defined as the rate of change of the position of an object with respect to its time.
It's the vector quantity of speed as it has both magnitude and direction.
Hope this helps :)
Answer:
the correct answer is B
Explanation:
The kinetic model of the movement describes that the movement of the molecules increases with the increase of their internal energy, which in a macroscopic sample is reflected in an increase in the temperature of the sample.
The sample graph shows the function of temperature over time, which is why our kinetic model establishes that there is an increase in the movement of water molecules.
Consequently the correct answer is B
Answer:
The answer to your question is: Ep = 14715 Joules
Explanation:
Data
mass = 50 kg
Potential energy = ?
height = 30 m
g = 9.81 m/s²
Equation
Ep = mgh
Substitution
Ep = (50)(9.81)(30)
Ep = 14715 Joules
