Nonmetals in the periodic table have a negative oxidation number. Which statement best explains why?

Physics

For safety reasons, a worker’s eye travel time in a certain operation must be separated from the manual elements that follow. Th
iogann1982 [59]

Answer:

The answer is 12.67 TMU

Explanation:

Recall that,

worker’s eyes travel  distance must be = 20 in.

The perpendicular distance from her eyes to the line of travel is =24 in

What is the MTM-1 normal time in TMUs that should be allowed for the eye travel element = ?

Now,

We solve for the given problem.

Eye travel is = 15.2 * T/D

=15.2 * 20 in/24 in

so,

= 12.67 TMU

Therefore, the MTM -1 of normal time that should be allowed for the eye  travel element is = 12.67 TMU

Anna35 [415]

Answer:

t= 1.2 hours

Explanation:

Define first di distance between the points, so

\bar{x}_{canoe}=2*(2+3)=10

\bar{x}_{water}=2*2=4

The distance is

d= \bar{x}_{canoe}- \bar{x}_{water}

d= 10-4 = 6miles

t = \frac{x}{v} = \frac{6}{2+3}

t= 1.2 hours

What is the mechanical advantage of the wheel and axle shown below?
BigorU [14]

The correct answer is A. 32.5

Mechanical advantage is the ratio of force that is input into a machine to the force output.

Mechanical advantage of a wheel and axle is calculated by dividing the radius of the wheel by that of the axle.

MA=R/r where R is the radius of the wheel and  r is the radius of the axle.

Substituting for the values in the question gives:

MA=26cm/0.8cm

    =32.5
