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

How long in seconds will it take a car traveling at 100 miles/hour to travel the length of an American Football field?

Mrrafil [7]

Answer:

It will take 2.45 seconds.

Explanation:

A football field measured 120 yards, that is arround 0.068 miles, the car is moving with a constant speed so the formula we have to apply for this is:

$t=\frac{x}{v}\\where\\x=distance\\v=speed\\$

$t=\frac{0.068}{100}\\t=0.00068hrs$

in order to obtain the time in seconds:

$tsec=0.00068hr*(\frac{3600sec}{1hr} )\\tsec=2.45 sec$
