Answer / Explanation:
Regarding α and β Particles in Windowless Counter, the range of α particles is lower than β particles. Alpha particles typically have range less than the dimensions of the gas chamber so that proportional counters are able to easily record. Hence, with almost 100% efficiency, each particle which enters the so called active volume.
Then, since the pulse height spectra depends on the number of ion pairs which have formed, an aplha particle with higher energy creates more ion pairs in the chamber. However, beta particle range usually exceeds the dimensions of the chamber and therefore most of the betas hit the walls where they deposit energy. Then, fewer ion pairs are formed because very few β’s give their energy to the bulk gas.
Answer:
1). Linear and syndiotactic poly(vinyl chloride); linear and isotactic polystyrene
2). Network phenol-formaldehyde; linear and heavily crosslinked cis-isoprene
3). Linear polyethylene, lightly branched isotactic polypropylene
Explanation:
1). It is very much possible to decide for the two polymers. Here the linear as well as the syndiotactic poly(vinyl chloride) are likely to be crystallize; the side - group phenyl of the polystyrene is more bulkier than CI side group for the poly(vinyl chloride). The syndiotactic as well as the isotactic isomers are likely to crystallize equally.
2). No we cannot decide for the two polymers. Both of them are crosslinked and the network polymers may not crystallize.
3). It is a possible to decide the two polymers. The linear polyethylene is likely to crystallize.
It depends on how big the land
fill is. I would say it could be but it depends on how much waste and Jim much land..this probably wasn’t too helpful but I tried
Answer:
w = 10.437 kips
deflection at 1/4 span 20.83\E ft
at mid span = 1.23\E ft
shear stress 7.3629 psi
Explanation:
area of cross section = 18*76
length of span = 32 ft
moment = 334 kips-ft
we know that
moment = load *eccentricity
334 = w * 32
w = 10.437 kips
deflection at 1/4 span
= 20.83\E ft
at mid span
shear stress
Advantages of liquid electrical tape over conventional electrical tape for covering exposed conductors is given below.
Explanation:
- Electrical tape and "regular" adhesive tape is that electrical tape is stretchy. This allows the tape to wrap around a wire junction and still grab the insulation to either side. This helps keep the tape in place.Where as Regular tape is likely to get stiff, lose adhesion, and slide away from the joint, leaving it exposed.
- The electrical tape is able to withstand much more heat and like the others said the adhesive is better and it can stretch 200 percent.
- Electrical tape is a suitable long-term or permanent solution in various applications.Heat-shrink sleeving, spiral wrap, flexible conduit, self-amalgamating tape, rubber sleeves, junction boxes, table ties/clips, grommets, cable markers, etc. are all better solutions for almost any given use of electrical tape other than to conventional electrical tape which has temporarily hold, bundle, insulate, or mark a cable.
- This kind of type is often used by electricians. It's typically made of slightly stretchy PVC vinyl, and is backed with a pressure sensitive rubber-type adhesive. It has good insulative properties, and is perfect for protecting wire splices and providing extra insulation on electrical cords. it's also available in a variety of other colors (like red, green, yellow, green, and white) that can be used for color-coding.
