Because air and water have different density.
Air is less dense than water.
So, the light will bend towards normal.
Thus, the angle of refraction is smaller than angle of incidence.
This phenomena is known as refraction.

Two objects are dropped from a bridge, an interval of 1.00 s apart. What is their separation 1.00 s after the second object is r
katen-ka-za [31]

Answer:

<em>171.5m</em>

Explanation:

The velocity of sound in water = 343m/s

Time taken = 1.00secs

using the formula to calculate the distance

2x = vt

x is the distance

v is the speed of sound

t is the time

x = vt/2

x = 343(1)/2

x = 171.5m

<em>hence their separation 1.00 s after the second object is released is 171.5m</em>

A 60kg block is at rest on a ramp inclined at 35 degrees.
weeeeeb [17]

Answer:

Explanation:

(a)Gravitational Force is W=mg

Frictional force is f

Normal force is N

(b)Since the block is in Equilibrium therefore from diagram we can see that  

f=mg\sin \theta

f=60\times 9.8\times \sin 35

f=337.26 N

(c)Magnitude of Normal Force

N=mg\cos \theta =481.66 N

(d)friction is also given by

f=\mu mg\cos \theta

and f=mg\sin \theta

thus tan \theta =\mu

\mu =0.7

Black smokers are hot volcanic vents that emit smoke deep in the ocean floor. Many of them teem with exotic creatures, and some
erica [24]

If the density of water does not vary and the vents range in depth from about 1500 m to 3200 m below the surface, then the gauge pressure at a 2452-m deep vent is 224.268 atm.

Calculation:

Step-1:

It is given that the vents range in depth from about 1500 m to 3200 m below the surface. If we are assuming that the density of water does not vary. Then it is required to calculate the gauge pressure at a 2452-m deep vent.

The gauge pressure at a particular depth of ocean water is calculated as:

$$P=\rho g h$$

Here \rho is the density of water, P is the required pressure, h is the depth of water, and g is the gravitational acceleration.

Step-2:

Now we are substituting the values to calculate the pressure at the depth of 2452-m.

$$\\\begin{aligned}\\P&=\rho gh\\&=1030 (\text{ kg/m}^3)\times 9.8 (\text{ m/s}^2)\times 2452 \text{ m}\\&=24.75\times 10^6 \text{ Pa}\times\frac{1 \text{ atm}}{10.1325 \times10^4 \text{ Pa}}\\&=224.268 \text{ atm}\\\end{aligned}\\$$

Is it possible for an inverted pyramid to exist, like the one show here? Explain your answer.
Korvikt [17]

Answer:

Not possible, if we talk about real pyramids

Explanation:

There is no image shown in the question statement. However if we talk about the pyramids as we find them in Egypt, we cannot get a stable inverted pyramid because of the difficulty in terms of balancing it from its centre of mass. In theory one might balance the forces, but in actual, to balance all the load of the structure just on a point is extremely difficult.

However, the term inverted pyramid can be found in ecological system and also used as metaphors in English literature

How does the principle of electromagnetism explain the interaction between Earth’s magnetic field and the solar wind? I get that
siniylev [52]

Answer:

Explained below.

Explanation:

Electromagnetism is defined as the study of the electromagnetic force that takes place between two or more electrically charged particles.

Now, in electromagnetic interaction, the charged particles tend to interact in an electromagnetic manner through the process of exchanging photons. Therefore, it was concluded from various experiments that the magnetic fields lines of forces were always closed, thereby eliminating the possibility of any magnetic monopole in such a manner that within a particular magnetic field, there will be two poles and in the solar system, the electromagnetic attraction between earth magnetic field and solar wind will be by way of a field.
