A 100 Newton force applied to a machine lifts a 400 N object. What is the actual mechanical advantage of
uranmaximum [27]

Answer:

m = 4

Explanation:

It is given that,

A 100 Newton force applied to a machine lifts a 400 N object.  

We need to find the mechanical advantage of  this machine.

The mechanical advantage of a machine is given by the ratio of output force to the input force.

Here, output force is 400 N and input force is 100 N

So, mechanical advantage becomes :

m=\dfrac{400}{100}\\\\m=4

So, the mechanical advantage of this machine is 4.

5) With a power of 0.12HP it is possible to move a piece of furniture from one place to another, in 14 seconds, applying a force
viva [34]

Answer:

a) 1250 J

b) 17.9 m

Explanation:

Convert horsepower to watts:

0.12 HP = 89.5 W

a) Work = power × time

W = (89.5 W) (14 s)

W = 1250 J

b) Work = force × distance

1250 J = (70 N) d

d = 17.9 m

Three 100 nCcharged objects are equally spaced on a straight line. The separation of each object from its neighbor is 0.3 m. Fin
Rainbow [258]

Answer:

0N

Explanation:

Parameters given:

Q1 = Q2 = Q3 = 100 * 10^(-9) C

r = 0.3 m

The net force on the middle charge is:

F = F(1,2) + F(2,3)

Where F(1,2) = force due to Q1 on Q2

F(2,3) = force due to Q3 on Q2

F(1,2) = k*Q(1)*Q(2)/r²

F(1,2) = [9 * 10^9 * 100 * 10^(-9) * 100 * 10^(-9)]/(0.3²)

F(1,2) = 0.001N

F(2,3) = k*Q(2)*Q(3)/r²

F(2,3) = [9 * 10^9 * 100 * 10^(-9) * -100 * 10^(-9)]/(0.3²)

F(2,3) = -0.001N

Therefore,

F = 0.001 - 0.001

F = 0N

A sample of an ideal gas has a volume of 0.0100 m^3, a pressure of 100 x 10^3 Pa, and a temperature of 300K. What is the number
alexdok [17]

Answer:

Explanation:

pV = nrT

n = PV/RT

n = (100*10^3)(.01)/(300*0.082057)

n = 40.62 moles
