Answer:
Some of the demerits or disadvantages of using a very slow castings rates in production of metal by the method of casting includes, with the solidification of metal, it may begin even before the mold is filled fully, which may result in defects such as shrinkage.
Secondly, the rate of slow casting will create castings that have a grain coarse structure that will affect the strength of the castings.
Explanation:
Solution
The disadvantageous of slow casting rates in the production of metals by casting method is explained below:
(1) The solidification of metal may start even before the mold is filled completely, which may create or produce defects such as mis-runs and shrinkage and shrinkage cavity.
So, the slow cavity rate will produce partial and incomplete castings
(2) Slow casting rate will produce castings which have a coarse grain structure which therefore affects the strength of the castings adversely.
Administrative controls can be broken down into two categories; programs such as HAZCOM and activities such as housekeeping is a TRUE statement.
Explanation:
- Administrative controls (or work practice controls) are changes in work procedures such as written safety policies, rules, supervision, schedules, and training with the goal of reducing the duration, frequency, and severity of exposure to hazardous chemicals or situations.
- Some common examples of administrative controls include work practice controls such as prohibiting mouth pipetting and recapping of needles, as well as rotating worker shifts in coal mines to prevent hearing loss.
- Administrative controls are fourth in larger hierarchy of hazard controls, which ranks the effectiveness and efficiency of hazard controls.
- The two categories of administrative controls programs and activities.

This is a function written in Python Programming Language to check whether a given number is prime or not.
def is_prime(n):
if (n==1):
return False
elif (n==2):
return True;
else:
for x in range(2,n):
if(n % x==0):
return False
return True
print(is_prime(9))
