Answer:

The speed, as they crash together, is the same than before the crash, but with opposite directions. In this context, we recur to the collision theory in physics, which says that the amount of movement of each particle before the collision is the same than after the collision, due to the conservation of the amount of movement, which can be described like this: $\Delta p=0$ . This expression means that in a isolated environment (which is present in a neutron's collision), the total amount of movement doesn't change.

Therefore, the speed of neutrons is the same before and after the collision. Specifically the number of this speed depends on the experiment.

This involves shooting electrons (from an accelerator) at a target or protons. This technique provided evidence for the existence of quarks. proton-antiproton scattering as well.
hope this helps

An observer measures the length (L), width (w), and height (h) of a box while stationary relative to the box. The observer then

Elenna [48]

Answer:

b. less than w.

Explanation:

In this question, the application of length contraction is what helps us come to our conclusion. When an object moves very fast (relative to the observer), the length of the object seems to be smaller than it actually is (again, for the observer).

This is supported by the length contraction equation below:

L = $L_0\sqrt{1-\frac{v^2}{c^2} }$

Here, L is the observed length

$L_0$ is the original length of the object

v is the relative speed between the object and the observer

and c is the speed of light

Using this equation, we can see that as the speed between the object and the observer is increased to be close to that of light, the square root in the equation gives us values less than 1.0

This effectively decreases the length that is observed.

What are the differences between balloon framing and platform framing? What are the advantages and disadvantages of each? Why ha

Licemer1 [7]

Answer:

Difference : Balloon framing go through from foundation to top floor while Platform do not

advantages and disadvantages

Balloon framing : It has less vertical shrinkage ( disadvantage )

platform framing : It has more vertical shrinkage and fire stops ( advantage )

platform framing : It is easier and safer to use

Reason for platform framing :

Due to these advantages Platform framing has become a better choice

Little added fire stopping is required in platform framing because of double tap plate present which can act as as a fire stop

Steel beam/ glue laminated wood beam is preferred at foundation level because wood beam under the ground will most likely shrink over time

Explanation:

Differences : Balloon framing a form of building houses using a special kind of timber construction its studs start from the foundation and go to all the way to the last floor while in Platform framing the studs are interrupted by floor platforms ( i.e. they do not go through like in Balloon framing )

advantages and disadvantages

Balloon framing : It has less vertical shrinkage ( disadvantage )

platform framing : It has more vertical shrinkage and fire stops ( advantage )

platform framing : It is easier and safer to use

Reason for platform framing :

Due to these advantages Platform framing has become a better choice

Little added fire stopping is required in platform framing because of double tap plate present which can act as as a fire stop
