A) is Ep= mgh so since you already have mg which is 500N and h which is 10m multiply them and your answer will be 5000J potential energy.

b) do the same thing as a except use 5m instead of 10m which gives you 2500N

c) the potential energy is transferred to kinetic since he’s at bottom of hill of mechanical energy. so kinetic energy would be 5000J since that’s the mechanical energy since at top of hill there’s 0 kinetic, making all the potential the same as the mechanical

Which words best describe the archer's results?
Inessa [10]

The words best describe the archer's results are  The correct option is A.

<h3>What is accuracy?</h3>

When in an experiment, a value is measured 5 times, then if the values measured are same for most of the time or like three times out of five, it said to be accurate. The phenomenon is accuracy.

Precision is about comparing the values to each other then find them near to each other.

Given is an archer's targets on the target board.

Accuracy compares the experimental value to the theoretical value (desired target)

So, when all the values are close to each other but not nearest to the theoretical value, then it is said to be precise but not accurate.

Thus, the correct option is A.

How do you think scientists figure out what they think the population will be in 2050?
laila [671]
They would most likely use statistics on the increase/decrease in population from previous decades and centuries. In addition to these statistics, they could use the birth and death rate and ultimately predict the increase within these next 30 years. They must also take climate change and other environmental factors into consideration when formulating such a bold prediction.

Sliva [168]

According to Newton’s law of universal gravitation, as we move to higher altitudes, the force of gravity on us decreases and as we gain mass, the force of gravity on us increases both are the true statement.  

<u>Explanation:  </u>

Newton law of universal gravity extends gravity beyond the earth's surface. This gravity depends on the masses directly and inverse to the distance square between their centers.

                                         F=G \frac{M \times m}{r^{2}}

Where,

F – Force, G – gravitational constant, M and m – masses in kg, r – distance in meters.

Since force is proportional to the masses of interacting objects. If the mass of any one object increases, gravity between them also gets increased. When moving to higher altitude, force decreases as the distance is inverse proportion to gravity.
