Answer:
Object C has the most potential energy.
Between A and B, we do not know which has more potential energy.
Explanation:
We know the object with the most potential energy and this is the object at C.
Potential energy is the energy due to the position of a body above the ground surface.
The higher a body is above ground, the more its potential energy.
Potential energy = mass x acceleration due to gravity x height
So;
Object C has the most potential energy.
Between A and B, we do not know which has more potential energy.
This is because, the height and mass of the objects are not quantified using numbers.
Potential energy is a function of mass and height and acceleration due to gravity but acceleration due gravity is a constant.
Answer:
4.34 mi at 
north of east
Explanation:
The displacement of an object in motion is a vector connecting its initial position to the final position of motion.
In this problem, the man has 2 different motions:
- 3.50 mi due east
- 2.57 mi due north
We can take the east direction as positive x-direction and north as positive y-direction, so these two motions can be written as:
Since the two motions are perpendicular to each other, the resultant displacement can be found by using Pythagorean's theorem; therefore:
We can also find the direction using the equation:
And therefore,
Answer:
The mild climate enabled Romans to grow wheat, grapes, and olives. This abundance o food supported the people and allowed Rome to prosper. While the climate made year-long agriculture possible, Rome also had the advantage to be near water. The Tiber River helped the agricultural system to prosper
