A simulation
A) Attempts to recreate a real-life set of conditions or events
B) Only develops ethics and roles (learning-to-be skills) and application (learning-to-do skills)
C) Is always designed to be fun
D) All of the above
Answer:
A) Attempts to recreate a real-life set of conditions or events
Explanation:
A Simulation is a scientific term that describes a perfect imitation or mimcs the operation of an existing or proposed process or system.
Simulation is applicable in various fields such as computer games, education, testing, training etc.
Characteristics of simulation are:
1. It is visual and interactive
2. It is timely based, most specifically, lesser in time compared to real life situation
3. It allows for comparison of multiple situation.
4. It seeks to match actual reality
Complete question:
A casting with a mass of 500 kg rests on a surface with a slope of 20° to the horizontal. The coefficient of friction is 0.25.
Calculate;
(a) the component of the weight of the object perpendicular to the surface
(b) the component of the weight of the object parallel to the surface
Answer:
(a) the component of the weight of the object perpendicular to the surface is 4,604.5 N
(b) the component of the weight of the object parallel to the surface is 1,675.9 N
Explanation:
Given;
mass of the casting, m = 500 kg
angle of inclination of the casting, θ = 20⁰
the coefficient of friction, k = 0.25
(a) the component of the weight of the object perpendicular to the surface;
F⊥ = mgcosθ
F⊥ = 500 x 9.8 x cos20
F⊥ = 4,604.5 N
(b) the component of the weight of the object parallel to the surface
F|| = mgsinθ
F|| = 500 x 9.8 x sin(20)
F|| = 1,675.9 N
Answer: gold and silver
Explanation:
Core historical themes. Motivations for colonization: Spain's colonization goals were to extract gold and silver from the Americas, to stimulate the Spanish economy and make Spain a more powerful country. Spain also aimed to convert Native Americans to Christianity.
