Answer:

n_{glass} = 1.65

Explanation:

As we know that the angle of incidence is given as

i = 50.0^o

also we have angle of refraction as

r = 27.7^o

now by Snell's law we know that

n_{air} sin i = n_{glass} sin r

1 sin50 = n_{glass} sin 27.7

now we have

n_{glass} = \frac{sin 50}{sin 27.7}

n_{glass} = 1.65

Convert 23 miles into feet.<br> **There are 5280 feet in 1 mile** *
zhenek [66]

Answer:

121440 feet is 23 miles.

5280 x 23= 121440

To check your answer just divide 121440 by 5280, which gives you 23.

Hopefully this helps you!

A 0.046 kg golf ball hit by a driver can accelerate from rest to 67 m/s in 1 ms while the driver is in contact with the ball. Ho
Flauer [41]

Answer:

Average force = 67 mn

Explanation:

Given:

Initial velocity u = 0 m/s

Final velocity v = 67 m/s

Time t = 1 ms = 0.001 sec.

Computation:

Using Momentum theory

Change in momentum  = F × Δt

 (v-u)/t =  F × Δt

F × 0.001 = (67 - 0)/0.001

F= 67,000,000

Average force = 67 mn

2560 meters in 60 seconds, what is his average speed (velocity)
jok3333 [9.3K]
42.6 is the answer I believe because you would do 2,560 divided by 60 if I'm correct.
