Answer: 2. The rubbish is separated first by hand, then through flotation (separating plastic and paper), magnets, and an eddy current method, which pings off aluminium and other metals. A laser beam identifies each type of plastic as it passes on a conveyor belt, then a timed jet of air pushes it into the appropriate bin. There are two broad types of recycling operations: internal and external. Internal recycling is the reuse in a manufacturing process of materials that are a waste product of that process. Internal recycling is common in the metals industry, for example. 3. Repurpose Glass, Plastic and Cardboard Containers.

As part of a blood drive on campus for the American Red Cross, you and your friends have just donated 500 ml of blood. You are n
Lunna [17]

D) no change in cardiac output, increased heart rate, decreased stroke volume occurs after blood donation

Explanation:

When a person donates blood, there is a slight loss of blood volume or hypovolemia. This triggers the baroreceptors of the blood; although does not trigger the osmoreceptor.

The baroreceptor responses are according to the arterial pressure which rises momentarily and results in increased sympathetic activity with decreased vagal activity.

These changes will lead to vasoconstriction, reduced stroke volume, increased heart rate or tachycardia which helps to maintain the cardiac output.

The soreness at the venepuncture site on the skin is due to bruising which is common after any needleprick. applying cold pack, elevating and resting the arm.

In order to compensate for the fluid volume loss and avoid dehydration, one must take plenty of fluids before and after blood donation.

Velocity calculation
svetoff [14.1K]
Answer choice: [C]:
_________________________________________

V = d / t  = 1800 mi / 40 min = 180 mi / 40 min = 45 mi / min .

Which very well could be "Answer choice: [C]:  45 m/min" ; except, this answer choice may have been written incorrectly—and should read:
                                                 "45 m/min."
________________________________________________________

Now, notice that all the answer choices given are in "meters" per (unit time—seconds or mins.

So, we need to convert:

45 mi.  to "meters", or "m".
______________________________________
Note the following conversions:
_______________________________________
 1 mi. = 1750 yd
______________________________________
3 ft. = 1 yd.
____________________________________

1 m = 3.2 ft.
_____________________

So, 1 mi. = ? m ;
_____________________
 1 mi * ( 1760 yd/ mi) * (3 ft / 1 yd) * ( 1m / 3.2 ft) = _?_  m ?
_____________________________________________________
On the "left hand side" , the units of  "mi", "yd", and "ft" ; cancel to "1" ;
  ____________________________________________________
    and we are left with:
______________________________________
[(1760 * 3)]  /  [(3)*(3.2)]   m  = (5280 / 9.6) m  =  550 m .
______________________________________________
So, we have:  550 m / min ; which match NONE of the answer choices.

However, it is possible that choices A or B, which are given in "m/sec" (meters per second); are among the correct choices.
____________________________________________

So, we convert:   550 m / min to:   "m / sec " ;
______________________________________
( 550 m/ min)*(1 min/ 60 sec) =  (550/60) m/sec = (55/6) m/ sec
                                                                                    = 9 1/6 m / sec .
_____________________________________________________
                                                                 which is:  None of the above.
______________________________________________________
                     Unless the answer choices were written incorrectly.
