What is the critical angle for the interface between water and light flint? nflint= 1.58, nwater=1.33?
Angelina_Jolie [31]
When light crosses the interface between a medium with higher refractive index and a medium with lower refractive index, there is a maximum value of the angle of incidence after which there is no refraction, but all the light is reflected, and this maximum value is called critical angle.

The critical angle is given by
\theta_C = \arcsin ( \frac{n_2}{n_1} )
where n1 is the refractive index of the first medium while n2 is the refractive index of the second medium. In our problem, n1=1.33 and n2=1.58, so the critical angle is
\theta_C = \arcsin ( \frac{1.33}{1.58} )=57.3 ^{\circ}

A man pushes a box along a flat, frictionless surface using a force of 500 N. The box was moved a distance of 2.5 m. The actual
andrey2020 [161]

Answer:

Workdone = 1250Nm

Explanation:

<u>Given the following data;</u>

Force, F = 500N

Distance, d = 2.5m

Workdone is given by the formula;

Workdone = force * distance

Substituting into the equation, we have

Workdone = 500 * 2.5  

Workdone = 1250Nm

Therefore, the actual work done by the worker is 1250 Newton-meter.

The sum of potential and kinetic energies in the particles of a substance is called energy. True or False
harina [27]
<h2>Answer: False</h2>

Explanation:

This sentence is the description of the mechanical energy.

In this sense, the mechanical energy of a body or a system is that which is obtained from the speed of its movement (kinetic energy) or its specific position (potential energy), in order to produce a mechanical work.

That is to say: The mechanical energy involves both the kinetic energy and the potential energy (which can be elastic or gravitational, for example).

In addition, it should be noted that mechanical energy is<u> conserved in conservative fields and is a scalar magnitude.</u>

Therefore:

<h2>The sum of potential and kinetic energies in the particles of a substance is called  <u>Mechanical Energy</u></h2>
