What changes if the light is underwater and the light goes into air

Physics
1 answer:
grin007 [14]4 years ago
3 0

Answer:

Therefore, when a light ray traveling through air enters water or glass it slows down, refracts, and bends toward the normal line. ... For example, when light goes from glass or water to air, it speeds up. Refraction changes how objects look.

A woman drives a car from one city to another with different constant speeds along the trip. She drives at a speed of 80.0 km/h
romanna [79]

Answer:

Total distance traveled= 75.36km (point at which she reaches her destination.)

Explanation:

With the speed and time data we can calculate the distance traveled on each path, but first we must transform the time units from minutes to hours:

First ride:

v=80km/h     t=25min*1h/60min=0.42h

distancie= v*t = 80km/h * 0.42h =33.6km

Second ride:

v=65.0km/h   t= 20min*1h/60min= 0.33h

distance= 65.0km/h*0.33h=21.67km

Stop: 60min= 1h  distance=0km

third ride:

v= 40.0km/h   t= 30.0min *1h/60min= 0.5h

distance= 40.0km/h*0.5h=20km

Total distance traveled= 33.6km +21.76km+20km

Total distance traveled= 75.36km

Learning Goal: To be able to calculate work done by a constant force directed at different angles relative to displacement
svlad2 [7]

Answer:

Woke done, W = 4156.92 Joules

Explanation:

The work done by the force can be calculated as :

W=F\times s

W=Fs\ cos\theta

\theta is the angle between force and the displacement

It is assumed to find the work done for the given parameters i.e.

Force, F = 30 N

Distance travelled, s = 160 m

Angle between force and displacement, \theta=30

Work done is given by :

W=Fs\ cos\theta

W=30\times 160\ cos(30)

W = 4156.92 Joules

So, the work done by the object is 4156.92 Joules. Hence, this is the required solution.
