4m/s due north of the store
Explanation:
Given parameters:
Time taken = 45s
Displacement = 180m
Unknown
Velocity = ?
Solution:
Velocity is the displacement of a body per unit time. Velocity is a vector quantity that has both magnitude and direction.
Velocity = =

Answer:
True
False
False
Explanation:
4.True, When a positively charged object is connect to the 'ground' electrons flow from the 'ground' wire to neutralize the object.
5. False, Electrons can be influenced to move a specific way, but are free to move from atom to atom.
6. False, only electrons move from one object to another.
The coloring and water were more ordered before the stirring. The color was defined to on drop but now it has spread throughout the water.
This increase in disorder is dictated by the second law of thermodynamics, which states that the entropy, or state of disorder, of a system increases.
Answer: Newton, the unit of force, is defined based on Newton's Second Law (F=ma), as the force required to give a mass of one kilogram an acceleration of 1 meter/second2. Thus, it is derived from these other units.
Explanation:
Displacement is the area under the velocity/time graph. So for example this object's displacement in the first 3 seconds is (1/2)(3sec)(12.5 m/s)= 18.75m. (and then it starts backing up, displacement decreasing, after 3sec when velocity is negative).
But This object is never speeding up. Its velocity is smoothly decreasing at (25/6) m/s^2 (the slope of the graph). So the answer to the question is actually zero.
