A current runs to the right in a long, straight wire. What is the direction of the
SIZIF [17.4K]

Answer:

Into the page (Answer B)

Explanation:

Recall that the magnetic field that is created around a current conducting wire follows the right hand rule, where the direction of your fingers point in the direction of the magnetic field vectors when your thumb points in the direction of the current flow.

Use this to see that as you place the thumb of your right hand on the page pointing to the right (direction of the current in the wire). As you do so, you find the four fingers of your right hand entering the paper.

German physicist Werner Heisenberg related the uncertainty of an object's position ( Δ x ) to the uncertainty in its velocity (
timama [110]

According to the information given, the Heisenberg uncertainty principle would be given by the relationship

\Delta x \Delta v \geq \frac{h}{4\pi m}

Here,

h = Planck's constant

\Delta v = Uncertainty in velocity of object

\Delta x = Uncertainty in position of object

m = Mass of object

Rearranging to find the position

\Delta x \geq \frac{h}{4\pi m\Delta v}

Replacing with our values we have,

\Delta x \geq \frac{6.625*10^{-34}m^2\cdot kg/s}{4\pi (9.1*10^{-31}kg)(0.01*10^6m/s)}

\Delta x \geq 5.79*10^{-9}m

Therefore the uncertainty in position of electron is 5.79*10^{-9}m

Place each description in the correct category.
Kay [80]

Answer:

Elements- made of one type of atom

Can not be broken down

Compounds

Represented by formulas

Can be chemically broken down

Made of two or more types of atoms

Explanation:

An element is a chemical substance which cannot be further broken down into other chemical substances. An element is composed of only one type of atom. Examples of elements include, sodium, magnesium, gold, silver etc.

Compounds are formed when one or more elements combine in a definite ratio. Compounds are represented by chemical formulas which show the number of combining atoms e.g CaCO3, HF, etc. Some compounds can be broken down chemically.

rectangular plate, whose streamwise dimension (or chord c) is 0.2 m and whose width (or span b) is 1.8 m, is mounted in a wind t
Andrei [34K]

Answer:

See explaination for the details of the answer.

Explanation:

Density is a measurement that compares the amount of matter an object has to its volume. An object with much matter in a certain volume has high density An object with little matter in the same amount of volume has a low density. Density is found by dividing the mass of an object by its volume.

The Calculate of the chordwise distribution of the skin friction coefficient and the displacement thickness is done and represented in the attachment.

Please kindly check attachment for the step by step answer.
