Answer:

It is less than the ideal mechanical advantage

Explanation:

Hi, the actual mechanical advange is less than the ideal. This happens because when making calculations and designs of a machine, the scientist or engineer makes a lot of suppositions that doesn't always reflect the reality perfectly.

That difference between the suppositions and the reality is shown in the difference between the actual mechanical advantage and the ideal.

The porcentual difference between this two is what is called the efficiency

What eccentricity value results in a circular orbit?
Oxana [17]

Answer:

Zero

Explanation:

Given the equation of an ellipse:

\frac{x^2}{a^2}+\frac{y^2}{b^2}=1

The eccentrity of an ellipse is given by:

e=\sqrt{1-\frac{b^2}{a^2}}

For a circle, we have

a=b

Therefore the eccentricity of a circle is

e=\sqrt{1-\frac{1^2}{1^2}}=0

A 1.0-m long wire is carrying a certain amount of current. The wire is placed perpendicular to a magnetic field of strength 0.20
Marysya12 [62]

For a current-carrying wire running perpendicular to a magnetic field, the magnetic force acting on the wire is given by:

F = ILB

F = magnetic force, I = current, L = wire length, B = magnetic field strength

Given values:

F = 0.60N, L = 1.0m, B = 0.20T

Plug in and solve for I:

0.60 = I(1.0)(0.20)

I = 3.0A

What happens when white light shines onto a red filter?
Gnesinka [82]
The dye in between the two pieces of glass in the filter absorbs all the other colors in the white light except the red, and the red is the only light left to come out the other side. That's why the filter usually looks kind of red. It's also a big part of the reason why we call it a "red filter".

two bumper cars collide into each other and each caor jolts backwards what law is this isnt it newtons second law?
Yanka [14]
Yes because the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
