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
Answer:
B
Explanation:
The printing press allowed mass production of books that spread new scientific ideas.
Answer:
Explained
Explanation:
Landslides: landslides the sliding of large masses of mud under their own causing huge loss to life and property. Landslides quite common in mountain regions. The construction in mountain region has them more prone to landslides. Construction of roads, buildings and Motel, etc.
Floods: At the high altitude because of the presence of glaciers and lot of rivers originate from these glaciers. These rivers some time gets flooded causing huge destruction the valley region. The have have increased due various human activities like Construction of Dams, Rise the temperature because of the pollution cause by humans leading to rapid melting of glaciers.
Global participation is important in reducing resource depletion, because the problem is a global one. Local deforestation has global impacts. The demand for resources in one country can affect the depletion of resources in other countries. Without global participation, nonrenewable resources will continue to be depleted.
Elevation sorry if I’m wrong
