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
There are changes in temperature daily. An impact of South Indian high pressure cell and south Atlantic high pressure cell on movement of cyclones will lead to a lowering of warming air and dry conditions for almost all year round.
<h3>What is the impact of South Indian high pressure cell?</h3>
The South Atlantic, South Indian and Kalahari anticyclones are known to influence the climate of South Africa all year round
They tend to decrease the descending movement of warming air and dry conditions all year round and they also take place sue to the positions that they occupy is always changing.
This makes us to have changing seasonal climate and changing weather conditions all year round.
