Explain how the properties of alpha, beta and gamma radiation affect the level of hazard at different distances.
Mumz [18]

Answer:

Radiation can be absorbed by substances in its path. For example, alpha radiation travels only a few centimetres in air, beta radiation travels tens of centimetres in air, and gamma radiation travels very large distances. ... The thicker the substance, the more the radiation is absorbed

How do I find the x and y components and the resultant force?​
Dafna11 [192]

Explanation:

1) the diagonal force times the sine of the angle it makes will give you the vertical component or y component . use this to get the vertical components of all the diagonal forces . add all the vertical components as well as the vertical forces together

2) the diagonal force times the cosine of the angle it makes gives the horizontal component or x component. do this to get the x component of all the diagonal forces.

add all the x components as well as the horizontal forces together to get the final x component

3)using the triangle of vectors, the resultant force is calculated

sum of y component = 3.2N

sum of x component= 5.7N

resultant force = 6.5N

In an inductive circuit with an uncorrected power factor of 40 percent to 60 percent, the power factor can be corrected to withi
Olegator [25]

In an inductive circuit with an uncorrected power factor of 40 percent to 60 percent, the power factor can be corrected to within 5 percent of unity by the addition of a(n) capacitor.

<h3>What is capacitor?</h3>

A capacitor is a gadget that stores electrical energy in an electric field. It is an inactive electronic part with two terminals. The impact of a capacitor is known as capacitance. A capacitor is a gadget that stores electrical energy in an electric field. It is an uninvolved electronic part with two terminals. The impact of a capacitor is known as capacitance. While some capacitance exists between any two electrical conduits in closeness in a circuit, a capacitor is a part intended to add capacitance to a circuit. The capacitor was initially known as a condenser or compensator. This name and its cognates are still generally utilized in numerous dialects, yet seldom in English, one eminent exemption being condenser mouthpieces, likewise called capacitor receivers.
