When Liquid rock hits Earth's surface it becomes lava. When liquid rock is still under the Earth's surface, it is magma.
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>
Answer:
Cultural Diversity needs division of regions to understand it better as well as implement important policies.
Explanation:
Any country with great diversity requires special attention due to various religions, faith, ethnicity, race and culturally different communities residing in it. The amalgamation of different communities is known as the melting pot.
Due to the enormous size of the country it is essential to divide it into regions in order to govern it more efficiently.
The cultural complexity is a sensitive issue that requires balanced policies and their proper implementation.
Different geographic locations favor distinct lifestyles, business practices, languages and dialects. Thus, a diverse country needs to keep an account of all the demographic features.
Some regions are developed whereas some are backward, the Urban-Rural division, North-South division is an essential trait of country's sociopolitical features that can only be governed with proper attention to these conditions.
