Answer:

5850

Explanation:

MA = Force out/ Force in

.78 = out/ 7500

.78 times 7500 = input

Dacia wants to know how to determine the polar coordinate θ. What should Katarina tell Dacia?

crimeas [40]

Answer:

r = √ x² + y² and θ = tan⁻¹ y / x

Explanation:

The polar coordinates are obtained by transforming the Cartesian coordinates (x y) into others (r tés), for this we use to find r the Pythagorean theorem

r = √ x² + y²

To find teas we use trigonometries

tan θ = y / x

θ = tan⁻¹ y / x

In general the angle can be given in any unit, but the most used in physics is in radians

Find the angle of prism if the ray just fail to emerge from 2nd face When ray of light falls normallly on the face of prism of R

Usimov [2.4K]

The angle of prism is 41.81 degrees.

<u>Explanation:</u>

For no emergence to be taken place, inside a prism, Total Internal Reflection (TIR) should take place at the second surface. For TIR, at second surface, angle of refraction must be greater than critical angle. Angle of prism is related to refraction as,

$A>r_{1}+C$

Since, $r_{1}$ = C and $A \geq 2 C$

This implies $A \geq C$

$\sin A \geq \sin C$

$\sin A \geq \frac{1}{\mu}$

$\sin A \geq \frac{2}{3}$

when sin goes to other side become as sin inverse of value, and obtain the result as below,

$A=41.81^{\circ}$
