A roll of wire has a mass of 57.2 grams per meter what would be the length of 1400 kilograms of wire?
57.2 grams = 0.0572 kilogram(1,400 kilograms) / (0.0572 kilogram per meter) = 24,475.5 meters (rounded)
Object with mass 500km suspended by wire and upward force of 5.0N what is unbalanced force and acceleration of object?
Your object has distance units for mass, which is remarkable. Forget this homework stuff, report the huge massless object to the authorities if it is dangerous. If it seems safe, publish or perish.
When you are wiring up a lamp what does the grooved wire mean and what does the smooth wire mean?
grooved wire mean earth wire smooth wire mean suply wire
White wire a black wire a red wire and a bare wire?
white wire = neutral bare wire = ground black wire = line voltage red wire = returned from a switch, or the other phase of line voltage in order to supply 240VAC
Why does a battery snap have a red wire and a black wire?
Red wire=positive Black wire=negative
What is suspened load?
It is a mass or object hanging from a rope, string or wire.
What is a suspened load?
It is a mass or object hanging from a rope, string or wire.
How do you calculate the velocity of a transverse wave in a wire if the wire is under a tension of 1200N and each meter of wire has a mass of 10g?
v = square root of 1200/0.01
How many atoms are in a 1cm of copper wire and who calculate this?
We need to know the diameter of the wire to calculate the volume and the mass. Number of atoms is: 2,58.1023.r2, where r is the radius of the wire.
Why does the length of wire affect the resistance?
the longer the wire, the more mass the electrons have to travel thru. the more they have to travel thru, the more resistance. (and the resultant heat) the more electrically conductive the wire, the less resistance.
Can you multiple length and mass?
No. But you can multiply the length of something by the mass of a unit of length of that same something provided it is of uniform cross section. eg if a one meter length of wire ways 7 grams, a kilometer length of that wire will weigh 1000*7 grams.
What happens to the height of a weight hanging on a copper wire when its heated?
it went up because the mass increases
How does a mass airflow sensor work?
A mass air flow sensor, measures the mass(weight/temperature) of the air the engine is taking in. It does this by heating a wire in the sensor to a certain temperature and as the air flows past it cools the wire. The amount of current it takes to maintain the temperature lets the ECM know how much air it ingested by the motor and calculates the amount of fuel that is need.
How do you Calculate the diameter of a welding wire to kg?
To work out the mass of wire you need to know its volume. The wire is circular so that volume would just be the cross sectional area (pi * r^2) multiplied by the length of wire. Lets call the length L. The equation is then volume = pi * radius^2 * L. To get the mass of the wire we now multiply this equation by denstiy of the wire; that is how much the wire weighs per volume. Assuming the wire is steel this would be around 800Kg/m^3. So what you want to do is work out the volume as above, then multiply by 800, making sure that your units are consistant....ie lenght and radius in metres.
Does a wire weigh more according to relativity if electricity flows through it?
Yes. The effect is almost completely negligible but the electrons have more kinetic energy in the wire and this extra energy translates into additional mass.
What is the relationship between extension and mass?
Within a materials elastic limit, the extension of a uniform section (like a wire) will be proportional to the tensile load. The graph of load (mass) v extension will be a straight line
A roll of wire has a mass of 57.2 grams per meter what would be the length of 1400 kilograms of wire?
57.2 grams = 0.0572 kilogram(1,400 kilograms) / (0.0572 kilogram per meter) = 24,475.5 meters (rounded)
