Answer:

b. Transfer pipets; more accurate; measuring pipets.

Explanation:

Transfer pipets can be defined as an ungraduated or graduated disposable plastic instrument which are typically used in science laboratories to transfer or deliver liquids that are small in volume (microliters) . Also, they are generally being referred to as chemical

droppers, teat pipets, eye droppers, pasteur pipets, or droppers. It is made up of an ultra-clear long, slender tube with low density polyethylene (LDPE) and an integral molded bulb. The molded bulb allows a fixed volume of the desired liquid to be dispensed (transfered) or aspirated through compression and relaxation.

Hence, transfer pipets are calibrated to deliver one fixed volume and are more accurate than measuring pipets because of its long, slender tube which limits errors.

Pani-rosa [81]

Answer:

answer is given below

Explanation:

Central Limit Theorem: The Central Limit Theorem (CLT) is a statistical theory that gives a sufficiently large sample size with limited variations from the population, the average of all samples from the same population is approximately the same. . In addition, all models follow a nearly normal distribution model.

The given phenomenon is described in the central limit theory. In other words, if we repeatedly take independent random samples of size n from any population, when n is large, the sample distribution is the normal distribution pattern.

mean of the sample means

                    \mu _\bar x = \mu        .............1

and here standard deviation of the sample means is

                      \mu _\bar x = \frac{\sigma }{\sqrt{n}}      .........2

and This theory is found elsewhere in the field of statistics. Although the central limit theory may seem abstract and devoid of any application, this theory is actually important for statistical practice.

Fracture Mechanics: A specimen of a 4340 steel alloy having a plane strain fracture toughness of 45 MPa m ( ) is exposed to a st
vampirchik [111]

Answer:

a)  927 MPa

b)The specimen will experience fracture

Explanation:

a) Calculate critical stress for brittle fracture

σ = fracture toughness / (y √ π * surface crack)

  = 45  /  ( 1  \sqrt{\pi * ( 0.75*10^-3)}  )

  = 927 MPa

b) since critical stress( 927 MPa)  < 1000 MPa

hence : The fracture will occur
