A wind vane.........
Knowing some science make the right choice in buing a product.
No, they reverse their direction twice in every cycle, so with 50 Hz ac the electrons reverse 100 times every second. They don't have to move very far, because when a dc current flows in a wire the electrons might only move at 1 inch per second.
turn them around :)
No such device exists.
DNA has a double halux strand and the direction of the both halux is opposite to each other i.e the go in opposite direction.
An axel is a simple machine that relies on change in direction to make work easier. Furthermore, a simple machine is a device that makes work easier by increasing force or changing the direction of a force without electricity or other power sources.
A device that helps make work easier by changing the size or direction of force is a machine. A simple machine has only one movement. A wedge has a moving inclined plane. A inclined plane has a sloped surface.
It is simple one direction was not famous. Then they were famous so if you make ur own band then become famous then you might meet her
a device that helps make work easier by changing the size or direction of force
you dont, just take a nail and a wire and put it together with a battery.
Make a small prototype of a "Helical" windmill which is very simple and innovative if you can get a fabricator to work for you. And yes...a helical windmill is one which rotates(and in the same direction) irrespective of the wind direction.
A bike is not a simple machine. It is a compound machine. A bike is made of simple machines such as gears, a pulley, levers, wheel and axles, and screws.Firstly the Bicycle isn't a simple machine, its actually a compound machine meaning that it uses more than one simple machine to make it work.However the Pedals and Crankcase Sprocket and rear wheel sprocket are simple machines that fit into the Lever category as they allow you to exert and transfer torque.
You can tell by if she does things to make sure that you can see. She might always look at you and when you look at her direction she will turn to another direction fast.
You dont. A UJT is a much simple device than either of those BJT's Maybe you want to make a multivibrator out of BJT's?
machineAre you referring to simple machines?wikipedia.org/wiki/Simple_machinemachine
In the same direction of the force (if near the center of balance). If the force is away from the center of balance, it might spin it.
You have to make sure that the micro SD is the right one for your device. You might want to take it to a phone center if you need help.
