In a model of the hydrogen atom, the electron travels in circular orbits around the proton. What is the electric potential, in v

olts, due to the proton on an electron in an orbit with radius 2.08 x 10^-10 m?

Answer:

6.93 volts

Explanation:

q = magnitude of charge on proton = 1.6 x 10⁻¹⁹ C

r = radius of the orbit = 2.08 x 10⁻¹⁰ m

V = Electric potential due to proton on electron

Electric potential due to proton on electron is given as

V = \frac{kq}{r}

Inserting the values

V = \frac{(9\times 10^{9})(1.6\times 10^{-19})}{2.08\times 10^{-10}}

V = 6.93 volts

A worker pushes horizontally on a large crate with a force of 265.0 N and the crate moved 4.3 m. How much work was done?
trapecia [35]

Answer:

<h2>1139.5 J</h2>

Explanation:

The work done by an object can be found by using the formula

workdone = force × distance

From the question we have

work done = 265 × 4.3 = 1139.5

We have the final answer as

<h3>1139.5 J</h3>

Hope this helps you

Answer:

R= 20 ohm  

Explanation:

Given that

Current ,I = 6 A

Voltage difference ,ΔV = 120 V

Lets take resistance of the stem iron = R

We know that ,the relationship between current ,voltage difference and resistance is given as

ΔV = I R

R=\dfrac{\Delta V}{I}

Now by putting the values in the above equation we get

R=\dfrac{120}{6}\ ohm

R= 20 ohm

Therefore the resistance of the steam  will be 20 ohm.
