Answer:

Mechanical energy = 145 Joules

Explanation:

Given the following data;

Kinetic energy = 115J

Gravitational Potential energy = 30J

To find the mechanical energy;

Mechanical energy = kinetic energy + gravitational potential energy

Substituting into the equation, we have

Mechanical energy = 115 + 30

<em>Mechanical energy = 145 Joules. </em>

Mechanical energy can be defined as the ability (capacity) to do work. The two (2) main types of mechanical energy are;

<em>a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.</em>

<em>b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.</em>

Why did the map of Eastern Europe change so frequently for so many years?
kupik [55]
It changed so much because there were always European explorers heading out on voyages, for many reasons (like to trade with neighbouring countries, ferrying people from one land to the other, etc). During those voyages they found new lands, and so the maps had to be revised quite often because of these new discoveries.

Name four strategies/ways which the kruger national park combats rhino poaching
Firlakuza [10]
The rangers of South Africa refuse to give up on their ongoing battle against rhino poaching in South Africa and Kruger National Park. Despite the rescue efforts and extra funding, rhino poaching is now at an all time high, leaving conservationists with no choice but to dehorn rhino in order to protect the species.

<span>Protecting rhino from poachers has become part of the South African Government's National Development plan, as well as its environmental assets. Four Squirrel helicopters and new night vision equipment are among the latest efforts by the rangers of Kruger National Park to fight the battle against poaching. Poachers are currently winning the battle as rhino poaching increased by 30% in Kruger National Park, as of October 2015, yet the rangers of KNP insists that this battle is still far from over. </span>

<span>A number of rhino will be moved to safer locations in private game reserves to protect them from poachers. The rangers of KNP believe that there are 12 - 15 groups of poachers that operate within the park. They hunt in groups of 3 and are armed with hunting rifles and silencers. </span>

<span>The Hoedspruit Endangered Species Centre rescues and cares for young rhino that are orphaned. The location of these young orphaned rhino is a secret as one of the orphans were already victim to poachers. The orphans are kept under 24-hour surveillance and their progress can be witnessed via the live rhino cam at Africam.</span>
