Answer:

Explanation:

wavelength = velocity / frequency

= 3 x 10⁸ /5.25 x 10¹⁸

= .5714 x 10⁻¹⁰

= .05714 x 10⁻⁹

= .05714 nm .

b ) wave length in diamond

= wavelength in air / refractive index of diamond

= .05714 nm / 2.4

= .0238 nm .

c )

energy of one photon = hν where h is plank's constant and ν is frequency

= 6.6 x 10⁻³⁴ x 5.25 x 10¹⁸

= 34.65 x 10⁻¹⁶ J

= 34.65 x 10⁻¹⁶  / 1.6 X 10⁻¹⁹ eV

= 21.65 X 10³ eV .

d )

Energy does not change because its frequency does not change .

How many (whole number of) 91 kg people
Tcecarenko [31]

We are given that the maximum mass capacity is 1 metric ton or 1000 kg. Therefore the amount of people this can hold is simply the ratio of the maximum mass capacity over the mass of the person, that is:

people = 1000 kg / 91 kg

people = 10.98

 

So the elevator can safely occupy 10 people. We will not exceed to 11.

Which of the following is the best definition of an element?
Ostrovityanka [42]

Answer:

A. chemical substance whose atoms all have the same number of protons

Explanation:

An element is a substance which contains identical atoms that have the same number of protons in the nucleus.

Elements are arranged in the periodic table according to their atomic number (= number of protons): so atoms of different elements have a different number of protons in their nuclei.

For a neutral atom, the number of electrons around the nucleus is also equal to the number of protons.

Moreover, atoms of the same element can have a different number of neutrons, despite having the same number of protons - these atoms are called isotopes.

A 3.5 x 10-6 C charge is located 0.28 m from a 2.8 x 10-6 C charge. What is the magnitude of the force being exerted on the smal
Margarita [4]
The electrostatic force between two charges is given by Coulomb's law:
F=k_e  \frac{q_1 q_2}{r^2}
where
ke is the Coulomb's constant
q1 is the first charge
q2 is the second charge
r is the separation between the two charges

By substituting the data of the problem into the equation, we can find the magnitude of the force between the two charges:
F=(8.99 \cdot 10^{9} Nm^2C^{-2} ) \frac{(3.5 \cdot 10^{-6} N/C)(2.8 \cdot 10^{-6}N/C)}{(0.28m)^2}=1.2 N

can you help me create a sketch of two different objects with one that has a greater density than the other?
sergey [27]

I don't know how good you are at sketching ... I'm terrible. 
But you can put the point across in a dramatic way if you
can sketch a bowling ball and a basketball ... you'll need
to clearly identify them with the markings you sketch on
each ball. 

They're the same shape and nearly the same size, but
there's a huge difference in their densities.
