Which medium caused the most bending of light as it passed through?

Physics

babunello [35]4 years ago
4 0
I wasn't there observing the experiment while you and your class
performed it, so I don't really know how it was set up, or what
happened. 

But I can tell you this:  Light doesn't bend while passing through
any medium.  It only bends at the boundary where one medium
meets a different one.

What are the visible and invisible forms of moisture in the air?
Usimov [2.4K]
The invisible form is water vapor that is microscopic and found all around us. When the air is really hot you can see this water vapor above ground as if it's moving. The visible form is either water droplets that fall down as rain, or it's the clouds that are basically a form of moisture that is iced up because it's very cold so it condensed and formed a cloud.

Our best evidence and theoretical calculations indicate that the solar system began with a giant spinning system of gas and dust
Anna35 [415]

Answer:

Solar nebula.

Explanation:

A planet can be defined as a large celestial body having sufficient mass to allow for self-gravity and make it assume a nearly circular shape (hydrostatic equilibrium), revolves in an orbit around the Sun in the solar system and has a cleared neighborhood.

Basically, the planets are divided into two (2) main categories and these includes;

1. Outer planets: these planets are beyond the asteroid belt and comprises of jupiter, saturn, uranus and neptune, from left to right of the solar system.

2. Inner planets: these planets are the closest to the sun and comprises of mercury, venus, earth and mars.

These outer planets are made mostly of gases (hydrogen and helium) causing them to be less dense than the solid inner planets. These gases are generally known to be less dense in terms of physical properties.

Some examples of the planet found in the solar system are Mars, Venus, Earth, Mercury, Neptune, Jupiter, Saturn, Uranus, Pluto, etc.

Scientists have been able to understand and discover that, gravity pulled materials (low-density cloud of interstellar gas and dust known as a nebula) together forming the planetary bodies in our solar system.

A dark nebula can be defined as an interstellar cloud that is so dense as a result of high concentration of gas and dust and as such it obscures the visible wavelengths of light from stars behind it, thus appearing completely opaque (dark patch) in front of a bright emission nebula or in regions having plenty stars.

The characteristics of a nebulae are;

I. It contain hydrogen.

II. Clouds of gas and dust

III. It is needed to create a star.

A runner starts from rest and stops in 12 seconds. He covers
Schach [20]

Answer:

b 1.39 m/s²

Explanation:

Given the following data;

Time = 12 seconds

Distance, S = 100 m

Since it's starting from rest, the initial velocity is equal to 0m/s.

To find the acceleration, we would use the second equation of motion;

S = ut + \frac {1}{2}at^{2}

Where;

S represents the displacement or height measured in meters.

u represents the initial velocity measured in meters per seconds.

t represents the time measured in seconds.

a represents acceleration measured in meters per seconds square.

Substituting into the equation, we have;

100 = 0(12) + ½*a*12²

100 = 0 + 72

100 = 72a

Acceleration, a = 100/72

Acceleration, a = 1.389 ≈ 1.39 m/s²

A puck sliding on ice approaches a 20 degrees ramp at 10 m/s with coefficient of friction 0.2. How high will it go up the ramp a
timama [110]

Answer:

it will go up along the inclined plane by d = 9.62 m

Explanation:

As we know that puck is moving upward along the slide

then the net force opposite to its speed is given as

F_{net} = - mgsin\theta - \mu mgcos\theta

so here deceleration is given as

a = -g(sin\theta + \mu cos\theta)

now plug in all values in it

a = -9.81(sin20 + 0.2cos20)

a = -5.2 m/s^2

now the distance covered by the puck along the plane is given as

v_f^2 - v_i^2 = 2 a d

0 - 10^2 = 2(-5.2)d

d = 9.62 m
