Average velocity = displacement / time
In this case, since you move left 60, then right 60, you return to the starting point making the displacement zero.
average velocity = 0 / 60 sec = zero
the average speed is calculated using total distance traveled.
average speed = distance / time
average speed = 120 meters / 60 sec = 2 m/s
Answer:
Convection is the heat transfer due to the bulk movement of molecules within fluids such as gases and liquids, including molten rock. Condensation is the process by which water vapor in the air is changed into liquid water. Condensation is crucial to the water cycle because it is responsible for the formation of clouds. These clouds may produce precipitation, which is the primary route for water to return to the Earth's surface within the water cycle.
Explanation:
Their a difference....... A huge One
Well,
The sun's energy is produced mainly in the core, which has sufficient temperature to initiate nuclear fusion.
Hydrogen --> Deuterium --> Tritium --> Helium --> Beryllium? --> Carbon --> ? --> Silicon --> Iron/Nickel = Most massive stars<span />
Answer: a. net force is acting on object A in the same direction of its motion.
Explanation:
The second law of Newton states that the acceleration of a particular object is dependent on two main things which are the mass and force. According to the law, the acceleration of the object will be directly related to the net force while the acceleration is also relates inversely to the mass.
Therefore, based on the information given in the question, a force is acting on object A in the same direction of its motion.
