The speed of light in a transparent medium is 0.6 times that of its speed in vacuum. Find the refractive index of the medium.

grin007 [14]

<h2>Answer:</h2>

The refractive index is 1.66

<h2>Explanation:</h2>

The speed of light in a transparent medium is 0.6 times that of its speed in vacuum .

Refractive index of medium = speed of light in vacuum / speed of light in medium

RI = 1/0.6 = 5/3 or 1.66

A slingshot can project a pebble at a speed as high as 38.0 m/s. (a) If air resistance can be ignored, how high (in m) would a p

kipiarov [429]

Answer:

73.67 m

Explanation:

If projected straight up, we can work in 1 dimension, and we can use the following kinematic equations:

$y(t) = y_0 + V_0 * t + \frac{1}{2} a t^2$

$V(t) = V_0 + a * t$ ,

Where $y_0$ its our initial height, $V_0$ our initial speed, a the acceleration and t the time that has passed.

For our problem, the initial height its 0 meters, our initial speed its 38.0 m/s, the acceleration its the gravitational one ( g = 9.8 m/s^2), and the time its uknown.

We can plug this values in our equations, to obtain:

$y(t) = 38 \frac{m}{s} * t - \frac{1}{2} g t^2$

$V(t) = 38 \frac{m}{s} - g * t$

note that the acceleration point downwards, hence the minus sign.

Now, in the highest point, velocity must be zero, so, we can grab our second equation, and write:

$0 m = 38 \frac{m}{s} - g * t$

and obtain:

$t = 38 \frac{m}{s} / g$

$t = 38 \frac{m}{s} / 9.8 \frac{m}{s^2}$

$t = 3.9 s$

Plugin this time on our first equation we find:

$y = 38 \frac{m}{s} * 3.9 s - \frac{1}{2} 9.8 \frac{m}{s^2} (3.9 s)^2$

$y=73.67 m$

A fighter jet is launched from an aircraft carrier with the aid of its own engines and a steam-powered catapult. The thrust of i

kirza4 [7]

Answer:

2.5 x 10⁷ J

Explanation:

F = thrust of the engine = 2.3 x 10⁵ N

d = distance traveled = 87 m

Work done by the engine is given as

W = F d = (2.3 x 10⁵) (87) = 200.1 x 10⁵ J

W' = Net work done

W'' = work done by catapult

KE₀ = initial kinetic energy = 0 J

KE = final kinetic energy = 4.5 x 10⁷ J

Net work done is given as

W' = KE - KE₀

W' = 4.5 x 10⁷ J

We know that

W' = W + W''

4.5 x 10⁷ = 2.001 x 10⁷ + W''

W'' = 2.5 x 10⁷ J

The business practice of hiring workers in another country is known as globalization. insourcing. subcontracting. outsourcing.

tatiyna

outsourcing.

Explanation:

The business practice of hiring workers in another country is known as outsourcing.

Outsourcing involves the art of looking for cheap labors outside the shores of a country.

Since the same work can be done with a lesser cost, companies can decide to look beyond their boundaries.
Outsourcing is thriving in the aspect of remote works in the technological sector.
Some companies can decide to manufacture their goods outside of their base to due availability of cheap labor elsewhere.

Felicia left home at 8 a.m. driving her Ferrari at 80 mph from Rome to Sorrento. After spending 5 hrs in town, she drove back at

Alik [6]

Answer:

distance between Rome to Sorrento is 240 miles

Explanation:

given data

speed = 80 mph

time = 5 hours

reduce speed = 60 mph

to find out

distance between Rome to Sorrento

solution

let us consider time from Rome to Sorrento is x

we know 8 am to 8 pm total 12 hours and 5 hours in town spend so 12 -5 = 7

so we say that time back is 7 -x

we know distance was same

so distance is speed × time

compare both side distance

80 x = 60 (7-x)

80 x = 420 - 60 x

x = 3

so distance is = 80 (3) = 240 miles

distance between Rome to Sorrento is 240 miles
