Glass has a _____________ index of refraction than air

Physics
1 answer:
rewona [7]2 years ago
4 0

Glass has a <u>grater </u>index of refraction than air. The glass's and air's indexes of refraction will be 1.5 and 1, respectively.

<h3>What is an index of refraction?</h3>

The refractive index of a substance is a dimensionless quantity that specifies how quickly light passes through it in optics.

The index of refraction of the glass and air will be 1.5 and 1 respectively.

Hence,glass has a <u>grater </u>index of refraction than air.

A jet plane flying 600 m/s experiences an acceleration of 4.0 g when pulling out of the circular section of a dive. What is the
Brilliant_brown [7]

To solve this problem we will apply the concepts related to the equations of linear motion and angular motion in order to find the radius. Our values are given as,

g=9.81m/s^2

Then

4g= 39.24 m/s^2

The relation between the acceleration and the angular velocity and the radius is,

a_c=\omega^2*r

The angular velocity and the lineal velocity can be related as,

v=\omega r

The acceleration and the velocity was given, then

39.24=\omega^2 r

600=\omega r \rightarrow r = \frac{600}{\omega}

Replacing at the first equation we have,

39.24 = \omega^2 (\frac{600}{\omega} )

\omega = \frac{39.24}{600}

\omega = 0.0654rad/s

Now using this expression to find the radius we have that

r = \frac{600}{\omega}

r = \frac{600}{0.0654}

r = 9174.31 \approx 9200m

Therefore the correct answer is C.

Beyond what point must an object be squeezed for it to become a black hole
Naddik [55]

Answer:

Condition

\frac{m}{R} \geq \frac{c^{2} }{2*g}

Explanation:

Basically black hole is an object from which light rays can not escape it means   to go out from gravitational field , that body should thrown with speed greater then light.

Let's do some calculation

Gravitational potential at surface =-\frac{G*M*m}{R}

If we give kinetic energy equal to magnitude of Potential energy as on surface it will escape.

\frac{m*v^{2} }{2} =-\frac{G*M*m}{R}

⇒\frac{m}{R} =\frac{c^{2} }{2*G}

It will be more better for black hole if above ratio (analogous to density ) is more then above calculated

A 225-kg bumper car (and its occupant) is moving north at 98 cm/s when it hits a 198-kg car (occupant mass included) moving nort
stira [4]
To solve the problem you must first know that by keeping the linear moment P1 = P2. You must find P1 from the system and equal it to P2 of the system, from that equation you clear the final velocity 1. Which will result in V1f = 60.16 cm / s to the north.I attach the solution.
