Why can't theories become laws?

Physics
1 answer:
shtirl [24]3 years ago
7 0

Since each serves a different purpose, theories cannot become laws. Explaining how or why a natural phenomenon occurs is what the set of ideas called theories do. On the other hand, mathematical relationships that describes what happens are what is done by laws.

 

Let me show an example that illustrates the points. Describing what happens in the natural world are done by the mathematical formulas called the Gas Laws. In this example, it would show that by using the Gas Laws, I will be able to predict with great accuracy the pressure if I double the temperature of a sealed gas. This idea is a law since the relationship is mathematical and it tells us what will happen.

 

<span>On the other hand, in order to explain why gases behave like the way they do, we must use the kinetic molecular theory.</span>

a coin press creates a pressure of 3.20*10^8 Pa on a nickel of radius 0.0106 m. how much force does the press exert on the coin?
Naya [18.7K]

Answer:

1.13 x 10⁵N

Explanation:

Given parameters:

Pressure of the coin press = 3.2 x 10⁸ Pa

radius of the nickel coin = 0.0106m

Unknown:

Force of the press on coil = ?

Solution:

Our knowledge of pressure will help us solve this problem.

Pressure is defined as the force applied per unit area on a body.

              Pressure  = \frac{force}{area}

  Force = Pressure  x  Area

 Since the pressure is known;

Area of the coin = Area of a circle = π r²

 where r is the radius of the coin;

Area of the coin = π x 0.0106²  = 3.53 x 10⁻⁴m²

  Force = 3.2 x 10⁸ x  3.53 x 10⁻⁴  = 1.13 x 10⁵N

You are walking from your math class to your science class. You are carrying books
kolezko [41]

Answer:

1800J

Explanation:

Given parameters:

Weight of the book  = 20N

Total distance covered  = 45m + 15m + 30m  = 90m

Unknown:

Total work performed on the books  = ?

Solution:

To solve this problem we must understand that work done is the force applied to move a body through a certain distance.

So;

    Work done  = Force x distance

  Work done  = 20 x 90  = 1800J

12345 [234]

Answer:

6.49 x 10^-8 N

Explanation:

formula is

F= G * ((m1 * m2)/r^2)

F = 6.67x10^-11 * ((6.8*6.8/.218)

F = 6.49 x 10^-8 Newtons
