A steam governor uses negative feedback to control the speed of a steam engine. Suppose a steam governor has two balls that are

each rotating with a tangential speed of 3.7 m/s. The balls are 0.10 m from the rotation axis, and the centripetal force on each ball is 670 N. What is the mass of one of the balls? Pls help

Hello! Sorry this is a little late!

The answer to your question would best be option C, y<span>es, because electric charges have electric fields surrounding them that allow them to exert forces on other objects without touching them.

I just took this test, and can 100% confirm this is the correct answer!

Hope this helps, and have a great day! :)</span>

name the metal which form the filament of an electric bulb. what is the function of contact wire in a bulb.​
Natalka [10]

Answer:

tungsten wire

Explanation:

incandescent light bulbs consist of an air-tight glass enclosure (the envelope, or bulb) with a filament of tungsten wire inside the bulb, through which an electric current is passed. Contact wires and a base with two (or more) conductors provide electrical connections to the filament

Can a plane mirror firm a real image ? if yes tell me how ?​
alexdok [17]

Answer:

Explanation:

A plane mirror will produce a virtual image of a real object. But it is correct that a plane mirror will also produce a real image of a virtual object.A virtual image An image in a mirror is a virtual object, which can in turn be used to create another image. This can occur when you have more than one optical element in the optical system. Then the object of one component becomes the image of the next optical component.

So the answer is Yes it will!!!!

Area of triangle, ECD
Area, A= 60 square inches
Base, b= 12in
Height, h=?

Note that Area of a triangle = 1/2×b×h
Substitute the values: 60 = 1/2×12×h
60 = 6h
h = 10in

The height is 10in.



Coincidentally, the height of the triangle is also the side of the square.
So side of square, L = 10in

Area of a square = L^2 or Side × Side
Area = 10 × 10
Area = 100 square inches.



The area of the trapezoid = area of square + area of triangle
The are of trapezoid = 100 + 60 inches squared = 160inches squared.
