The Coriolis<span> Effect causes winds and currents to form circular patterns. The direction that they spin depend on the hemisphere that they are in.

Currents. The horizontal and vertical circulation of ocean waters are called currents. Major causes of ocean currents include wind friction, gravity, and variation in water density in different parts of the ocean. Surface ocean currents are mainly caused bywind.

A ray in plastic has a critical angle of 44.4 deg when trying to enter air. What is the index of refraction for the plastic?

Elena-2011 [213]

Answer: 1.43

Explanation:

Given that:

C (critical angle) = 44.4°

n (refractive index of plastic) = ?

Apply the formula n = 1/sineC, the index of refraction for the plastic can be obtained by:

n = 1/sineC

n = 1/sine 44.4°

n = (1/0.6996)

n = 1.43

Thus, the index of refraction for the plastic is 1.43

A listener is sitting somewhere on the line between two loudspeakers that are 10 m apart. The speakers are each emitting a sine

prohojiy [21]

Answer:

57.17 Hz 114.34 Hz 285 Hz

Explanation:

The distance between the men and 1 speaker = 3.5 m

Distance between the men and second speaker = 10-3.5= 6.5 m

Here at this point there will be no sound so there will be destructive interference

Path difference $\Delta x=6.5-3.5=3$

We know that for destructive interference $\Delta x=(2m+1)\frac{\lambda }{2}=(2m+1)\frac{v}{2f}$

$3=(2m+1)\frac{v}{2f}$

$f=(2m+1)\frac{v}{6}$ here v is the speed of sound in air

So for m =0

$f=(2\times 0+1)\frac{343}{6}=57.17H$

for m =1

$f=(2\times 1+1)\frac{343}{6}=114.34Hz$

for m=2

$f=(2\times 2+1)\frac{343}{6}=285Hz$

An object is located 45.0 cm from a concave mirror. The focal length is 15.0

guajiro [1.7K]

The image distance is 22.5 cm

Explanation:

We can solve the problem by using the mirror equation:

$\frac{1}{f}=\frac{1}{p}+\frac{1}{q}$

where

f is the forcal length

p is the distance of the object from the mirror

q is the distance of the image from the mirror

For this problem, we have:

f = +15.0 cm (focal length is positive for a concave mirror)

p = 15.0 cm (distance of the object)

Therefore, solving for the image distance, we find:

$\frac{1}{q}=\frac{1}{f}-\frac{1}{p}=\frac{1}{15}-\frac{1}{45}=\frac{2}{45}\\\rightarrow q=\frac{45}{2}=22.5 cm$
