niobium metal becomes a superconductor when cooled below 9 k. its superconductivity is destroyed when the surface magnetic field

Furkat [3]

Niobium wire with a 2.60 mm diameter has a maximum current capacity of 500 A while still remaining superconducting.

<h3>Describe the present.</h3>

Current is the rate at which charge passes from one point on a circuit to another. In a circuit, a significant current flows when several coulombs or charge pass over the cross section of a wire. When the charge carriers are firmly packed inside the wire, high currents can be generated at low speeds.

<h3>What do current and electron actually mean?</h3>

Electron movement is referred to as electron current. The positive terminal receives electrons that are released by the negative terminal. Traditional current, usually referred to as just current, exhibits behavior consistent with positive charge carriers being the source of current flow. Regular current is received at the positive end and then flows to a negative terminal.

With 51 gallons of fuel in its tank, the airplane has a weight of 2390.7 pounds. What is the weight of the plane with 81 gallons

Shtirlitz [24]

Answer: 2561.7 pounds

Explanation:

If we assume the total weight of an airplane (in pounds units) as a <u>linear function</u> of the amount of fuel in its tank (in gallons) and we make a Weight vs amount of fuel graph, which resulting slope is 5.7, we can use the slope equation of the line:

$m=\frac{Y-Y_{1}}{X-X_{1}}$ (1)

Where:

$m=5.7$ is the slope of the line

$Y_{1}=2390.7pounds$ is the airplane weight with 51 gallons of fuel in its tank (assuming we chose the Y axis for the airplane weight in the graph)

$X_{1}=51gallons$ is the fuel in airplane's tank for a total weigth of 2390.7 pounds (assuming we chose the X axis for the a,ount of fuel in the tank in the graph)

This means we already have one point of the graph, which coordinate is:

$(X_{1},Y_{1})=(51,2390.7)$

Rewritting (1):

$Y=m(X-X_{1})+Y_{1}$ (2)

As Y is a function of X:

$Y=f_{(X)}=m(X-X_{1})+Y_{1}$ (3)

Substituting the known values:

$f_{(X)}=5.7(X-51)+2390.7$ (4)

$f_{(X)}=5.7X-290.7+2390.7$ (5)

$f_{(X)}=5.7X+2100$ (6)

Now, evaluating this function when X=81 (talking about the 81 gallons of fuel in the tank):

$f_{(81)}=5.7(81)+2100$ (7)

$f_{(81)}=2561.7$ (8) This means the weight of the plane when it has 81 gallons of fuel in its tank is 2561.7 pounds.

Calculate the maximum absolute uncertainty for R if:

erma4kov [3.2K]

Answer:

ΔR = 5 s

Explanation:

The absolute uncertainty or error in an expression is

ΔR = | $\frac{dR}{dB}$ | ΔB + | $\frac{dR}{dA}$ | ΔA

the absolute value guarantees to take the unfavorable case, that is, the maximum error.

We look for the derivatives

$\frac{dR}{dB}$ = 1

$\frac{dR}{dA}$ = -1

we substitute

ΔR = 1 ΔB + 1 ΔA

of the data

ΔB = 3 s

ΔA = 2 s

ΔR = 3 + 2

ΔR = 5 s

Choose the sequence of energy forms that best fits each item.

levacccp [35]

Answer:

1. chemical energy --> electrical energy --> light energy

2. Electrical Energy --> Mechanical Energy

3. Electrical Energy --> Heat Energy

4. Chemical Energy --> Thermal Energy --> Mechanical Energy

5. Nuclear Energy --> Light energy and thermal energy

6. Mechanical Energy --> Electric Energy

7. Chemical Energy --> Electrical Energy --> Sound Energy

8. Mechanical Energy --> Sound Energy

Explanation:

1.<u>FLASHLIGHT</u>:

chemical energy --> electrical energy --> light energy

The chemical energy from the cell batteries is converted to electrical energy, which is used to produce the light energy in form of flashlight.

2.<u>ELECTRIC SAW</u>:

Electrical Energy --> Mechanical Energy

The electrical energy from the socket is converted to the mechanical energy used to run the saw blade.

3.<u>TOASTER</u>:

Electrical Energy --> Heat Energy

The electrical energy from the socket is converted to the heat energy (thermal energy) used in browning the bread.

4.<u>GAS POWERED SCOOTER</u>:

Chemical Energy --> Thermal Energy --> Mechanical Energy

The chemical energy from fuel, such as petrol is converted to heat (thermal energy) in the engine by the process of combustion. This heat is then used to do work by conversion into mechanical energy, through piston movement, which in turn moves the shaft and the scooter.

5.<u>THE SUN</u>:

Nuclear Energy --> Light energy and thermal energy

The nuclear reactions on Sun provide nuclear energy which is converted into light and thermal energy that reaches us on earth.

6.<u>WIND TURBINE</u>:

Mechanical Energy --> Electric Energy

The mechanical energy is provided by wind when it rotates the blade of turbine. This is then converted to electrical energy b the turbine.

7.<u>IPOD</u>:

Chemical Energy --> Electrical Energy --> Sound Energy

The chemical energy i supplied by the battery of ipod, which is converted to electrical energy and that electrical energy is used to produce sound by ipod.

8.<u>SPEAKER VIBRATES</u>

Mechanical Energy --> Sound Energy

The mechanical energy due to vibration produces sound energy.
