Answer:

Refraction.

Explanation:

Refraction is where lighwaves are bent. your eye assumes that the object is where the light ray is coming from when it actually bent to come at your eye from that angle this is why straws appear slightly out of place in water.

A beam of light strikes a sheet of glass at an angle of 57.0°. with the normal in air. You observe that red light makes an angle

Lena [83]

Answer:

a) Red: 1.34

Violet: 1.40

b) Red: $2.23\times10^8\frac{m}{s}$

Violet: $2.14\times10^8\frac{m}{s}$

Explanation:

a) We should use Snell's law to find the index of refraction:

$n_{1}sin\theta_{i}=n_{2}sin\theta_{t}$

with n1 the index of refraction of air, n2 the index of refraction of the glass, θi the angle of the incident ray respects the normal an θt the angle between the refracted ray an the normal. It's common to approximate n1=1

solving n2 for red light:

$\frac{sin\theta_{i}}{sin\theta_{t}}=n_{2}$

$n_2=\frac{sin57.0}{sin38.1}= 1.34$

solving n2 for violet light:

$\frac{sin\theta_{i}}{sin\theta_{t}}=n_{2}$

$n_2=\frac{sin57.0}{sin36.7}= 1.40$

b) Index of refraction on a medium is defined as the ratio between the velocity of electromagnetic waves on vacuum (velocity of light c) and the velocity in medium (v):

$n_2=\frac{c}{v}$

solving v for red:

$v=\frac{c}{n_2}=\frac{3\times10^8}{1.34}=2.23\times10^8\frac{m}{s}$

solving v for violet

$v=\frac{c}{n_2}=\frac{3\times10^8}{1.40}=2.14\times10^8\frac{m}{s}$

A skateboarder is moving at a constant speed of

Flauer [41]

The amount of time that passes from when this skateboarder begins to slow down until she begins to move back down the incline is 8.75 seconds.

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

Speed = 1.75 m/s

Acceleration = -0.2 $m/s^2$

To calculate the amount of time that passes from when this skateboarder begins to slow down until she begins to move back down the incline, we would apply the first equation of motion;

<h3>The formula for the first equation of motion.</h3>

Mathematically, the first equation of motion for a decelerating object is given by this formula;

$V=U-at$

<u>Where:</u>

a is the acceleration.

V is the final speed.

U is the initial speed.

t is the time measured in seconds.

Substituting the given parameters into the formula, we have;

$1.75 = 0-(-0.2)t\\\\1.75=0.2t\\\\t=\frac{1.75}{0.2}$

Time, t = 8.75 seconds.

An objects speed is 2.40 m/s, and its momentum is 120.0 kg m/s. what is the mass of the object?

jarptica [38.1K]

Momentum is defined as

P = m*v

where m is the mass of the object
and v is the speed of the object

We find m.............> m = P/v = 120 [kg.m/s] / 2.4 [m/s] = 50 kg

The mass is 50 kg
