Answer:

Energy is found as:

E = 1.987·10⁻¹⁹ J

Explanation:

Energy of a single photon of infrared light can be found by using the following formula:

E=hf

where

E = in Joules

h = Planck's constant = 6.627×10 ⁻³⁴ J

f = frequency in hertz

It can also be written as:

E = \frac{hc}{\lambda}

where

c = 2.998×10⁸ ms⁻¹

λ = wavelength

Wavelength is given in the question which is:

λ = 1×10⁻⁶m

Substitute all the values in the Energy formula

E = \frac{hc}{\lambda}\\E = \frac{(6.627\cdot10^{-34})(2.998\cdot10^8)}{1\cdot10^{-6}}\\E = 1.987\cdot10^{-19}J

You are exerting 100N. Since there’s no NET force, then there must be exactly 100N pushing exactly back on your 100N to cancel it to exactly zero. Newton's first law states that whether a body is at rest or travelling in a straight line at a constant speed, it will remain at rest or continue to move in a straight line at a constant speed unless acted upon by a force.

A 50.6 g ball of copper has a net charge of 1.6 µc. what fraction of the copper's electrons have been removed? (each copper atom
Fynjy0 [20]
First figure out how many atoms you have with Avogadro's number.  Since there are 63.5 grams/mol and you have 50.6 grams, you have (50.6/63.5)6.022E23=4.7986E23 atoms.  Since there are 29 protons per atom, there are also 29 electrons per atom, so you should have a total of
29*4.7986E23=1.3916E25 electrons.
Since there is a positive charge you know some of these electrons are missing.  How many are missing can be found by dividing the charge you have by the charge on the electron:  1.6E-6/1.6022E-19 = 9.98627E12 electrons are missing.  
Now take the ratio of what is missing to what there should be:
9.98627E12/1.3916E25 = 7.1760873E-13
