I'm not so sure if it is 5 clicks or 0 clicks

Answer:

0 clicks would be detected on the far side of the aluminum shield. Alpha particles are not very penetrating. Paper, clothing or a few centimeters of air can effectively shield against alpha particles. However, if ingested or inhaled, alpha particles can be hazardous.

In this schematic, the total resistance is 50 ohms. 100 ohms. 1,000 ohms. 100 ohms 10,000 ohms
Mrrafil [7]

The total resistance of the given circuit is if the circuit contains 100ohms,1000 ohms,100 ohms and 10,000 ohms resistors.

Resistance is measured in ohms, and it is represented by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who concentrated on the connection between voltage, current and resistance. He is credited for planning Ohm's Regulation.

Resistance estimations are regularly taken to demonstrate the state of a part or a circuit.

  • The higher the resistance, the lower the ongoing current. On the off chance that strangely high, one potential reason (among many) could be harmed guides because of consuming or erosion.
  • The lower the obstruction, the higher the ongoing stream. Potential causes: protectors harmed by dampness or overheating.

Since resistors are connected in series, so we know that when resistors are connected in series, total resistance is given by the formula

Rₙ=R₁+R₂+R₃+---------------Rₙ

So, resistors value are 50 ohms. 100 ohms. 1,000 ohms. 100 ohms 10,000 ohms.

Therefore, total resistance is 50+100+1000+100+10000=10250ohm

Hence, total resistance is 10250ohm

If the distance from a light source triples, how does light intensity change? The intensity will be 3x greater. The intensity wi
Tcecarenko [31]

Answer:

The intensity will be 1/9 as much.

Explanation:

The intensity of the light or any source is inversely related to the square of the distance.

I\alpha \frac{1}{r^{2} }

Now according to the question the distance is increased by three times than,

\frac{I_{2} }{I_{1} }=\frac{r_{1}^{2} }{r_{2}^{2} }

Therefore,

\frac{I_{2} }{I_{1} }=\frac{r_{1}^{2} }{(3r_{1})^{2} }\\\frac{I_{2} }{I_{1} }=\frac{1}{9} \\{I_{2}=\frac{1}{9}{I_{1} }

Therefore the intensity will become 1/9 times to the initial intensity.
