has a lower standard of living
Answer:
A. 29.4 Joules
Explanation:
Given parameters:
Mass of the book = 1.5kg
Height of lift = 2m
Unknown:
Potential energy acquired = ?
Solution:
Potential energy is the energy due to the position of a body.
Mathematically;
Potential energy = mgh
m is the mass of the body
g is the acceleration due to gravity = 9.8m/s²
h is the height
Potential energy = 1.5 x 9.8 x 2
Potential energy = 29.4J
<u>Answer:</u>
<em>Rigel and Betelgeuse </em>
<em></em>
<u>Explanation:</u>
Rigel and Betelgeuse are counted in the brightest stars of the galaxy.
They form a pair in the Orion constellation.
The Rigel star is situated near the Equator. This star is invisible in the region around and above of latitude 82°N and can be seen from any part of the world. It is a blue white giant star. This makes Rigel helpful in navigation.
Betelgeuse is a red giant star which is visible from naked eye. It has the same diameter as that of Jupiter.
Mathematics and architecture are related, since, as with other arts, architects use mathematics for several reasons. Apart from the mathematics needed when engineering buildings, architects use geometry: to define the spatial form of a building; from the Pythagoreans of the sixth century BC onwards, to create forms considered harmonious, and thus to lay out buildings and their surroundings according to mathematical, aesthetic and sometimes religious principles; to decorate buildings with mathematical objects such as tessellations; and to meet environmental goals, such as to minimise wind speeds around the bases of tall buildings.
Answer:
For a geographer Map is the most important tool
Explanation:
Apart from the above geographers rely on various tools and techniques which are both Qualitative and Quantitative. Such as the Primary and secondary sources of data like surveys, questionnaires, and journals, etc. Apart from this use of satellite data to generate a comparative analysis of objects and there processing in terms of software i.e the GIS, GPS that store and breaks the data into an understandable format. Use of mental maps to understand the spatial construct of humans and the use of Aerial photography to help the geographers do an in-depth analysis of the landscape. Tools like the map which is again divided into various types such as the topological maps, hydrological maps, physiological, political and many more are essential tools of any geographer.
