a transverse wave passes through a slinky​

Step-by-step explanation:      

Step 1: Formula

10.0 = Meters

800 = Newtons

4.0 = Centre of Gravity

Explanation in words (Short Form)

-  We know all the formulas and that we are calculating the least force being applied. We know that balancing the pole at (A) with the weight of the gravity will equal more force at B times 10. So the answer will be 320 N because the B force will equal 3200. If we divide 3200 by 10. The answer will result as 320. So the final answer for this question is 320N

Answer:  

Balancing the pole at A with the weight acting at the centre of gravity = 800(4) Force at B multiplied by 10 = 3200 divided by 10 equals 320N

= 320N

Virtual reality is the observation method that exposes people to frustrations, temptations, pressure, and boredom in a controlled environment, and is used for firearms training in police departments.

Virtual reality is an observation technique that is utilized in police agencies for weapons training. It exposes individuals to frustrations, temptations, pressure, and boredom in a controlled setting.

Police officers' psychophysiological reactions are impacted when participating in virtual reality weapons training exercises.

Electroencephalographic (EEG) and heart rate variability (HRV) measurements, as well as VR simulator performance metrics, are used as outcome measures.

In order to facilitate the design of a biocybernetic adaption layer that generates real-time modulations in simulation difficulty based on specific physiological responses, we propose a psychophysiological model.

Hence, virtual reality is the observation method that exposes people.

When the chemical response is balanced, the mass of the reactant is equal to the mass of the reactant.

Grounded on the law of Conservation of Mass

We balance the chemical equation since tittles aren't destroyed in the process and the mass is conserved. The mass of the reactant is equal to the mass of the product. No new titles are created or destroyed, there was only rearrangement or regrouping of tittles. This also means the number of titles of rudiments in both the product and reactant is equal.

Taking into account the definition of density, the volume of the metal block is 3 m³.

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.

Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

[tex]density=\frac{mass}{volume}[/tex]

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

In this case, you know that:

Replacing in the definition of density:

[tex]5000 \frac{kg}{m^{3} } =\frac{15000 kg}{volume}[/tex]

Solving:

volume×5000 [tex]\frac{kg}{m^{3} }[/tex]= 15000 kg

volume= [tex]\frac{15000 kg}{5000 \frac{kg}{m^{3} }}[/tex]

volume= 3 m³

In summary, the volume of the metal block is 3 m³.
