<span>The total mass that should be placed in the right cap so
that the caps equilibrate at equal height is also 1 kg. if equilibrium should
be maintained the force in each side should cancel out, so to balance a 1kg
mass, a 1 kg mass should also be place on the opposite direction</span>
Answer:
20.88 m/s
Explanation:
Curve A:
theta = 12.7, vA = 19.1 m/s
Curve B:
Theta = 15.1 degree
Let the speed is v.
By the use of given formula
tanθ = v^2 / rg
For Curve A
tan 12.7 = (19.1)^2 / r g ...... (1)
For Curve B
tan 15.1 = v^2 / r g ......(2)
Divide equation (2) by equation (1), we get
tan 15.1 / tan 12.7 = v^2 / (19.1)^2
0.269 / 0.225 = v^2 / 364.81
v = 20.88 m/s
Answering the question, three examples of ways that physicists model the physical world include:
- Diagrams
- Equations
- Computer simulations
Computer simulations refer to the reproduction of behavior of a system with the use of a computer to simulate the results of a mathematical model that is linked with the system.
<h2>Further Explanation</h2>
Computer simulations are a tool that is very useful for mathematical modeling in various natural systems in physics.
Physicists write the rule of our universe using equations. Equations are an aspect of one of the models used by physicists to explain a particular situation.
Physicists use a diagram to convey information. It is a symbolic representation of information with the use of visualization techniques. Diagram provides other means for people to better understand information and process its importance.
Physics predictions about the physical world mainly depend on numerical stimulation, mathematics and empirical observations and Physicists models the physical world based on invariances and laws which are built on mathematical models.
The purpose of physics is to explain or describe everything around us. It described virtually everything around us accurately by deploring the law of physics.
However, physics is considered a natural science because it is based on mathematical analysis which is geared towards findings qualitative physical law for the physical world.
