Let’s get one thing straight electrons mean negative so I’m going to say very negative cause it spends more time around hydrogen atoms
B. Because virus need the hosts dna to multiply
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.
Correct answer. No definite shape.
