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  

So

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
