<u>Answer:</u> Option B: Reflection of light waves.

<u>Explanation: </u>

Reflection occurs when light waves bounce back from any surface. When the dog looks into the still water, it could see its own reflection. This is because the light waves incident from dog gets reflected on the surface of water and dog is able to see its own reflection.

Hence, the phenomenon responsible for appearance of dog's reflection on surface of water is reflection of light waves.

You just identified the image as a "reflection", so it's a pretty good bet that
the phenomenon involves reflection somehow.

Your dog can see his reflection in a mirror inside the house just as easily
as in the surface of the pond.  My dogs do it all the time.  The phenomenon
doesn't require water.

It's reflection of light waves.

Complete Question

The complete question is shown on the first uploaded image

Answer:

  The correct answer is option c

Explanation:

Faraday states that when there is a change in magnetic field of a coil of a wire, it means that there exist an emf in the circuit which in induced due to the change in the magnetic flux

From the question  two separate but nearby coils are mounted along the axis. First coil is connected to the power supply and the current flow is controlled by the supply.When the current alternates, it would produce magnetic field ,also the second coil is connected to an ammeter which indicates the current that is flowing in it when current in the first coil changes

This magnetic field that is produce would cause a change flux which would induce current in the second coil so the ammeter would indicate current flow in the second coil

a is incorrect because the current in fir coil is not change hence flux won't change therefore current is is not induced in second coil

This is the same reason b is incorrect

d is incorrect due to the fact that when the second coil is connected to a power supply by rewiring it to be in series with first coil the law of electromagnetism would no longer hold so he ammeter would show no reading

The speed v of a sound wave traveling in a medium that has bulk modulus b and mass density ρ (mass divided by the volume) is v=b
PilotLPTM [1.2K]

As it is given that Bulk modulus  and density related to velocity of sound

v = \sqrt{\frac{B}{\rho}}

by rearranging the equation we can say

B = \rho * v^2

now we need to find the SI unit of Bulk modulus here

we can find it by plug in the units of density and speed here

B = \frac{kg}{m^3} * (\frac{m}{s})^2

so SI unit will be

B = \frac{kg}{m* s^2}

SO above is the SI unit of bulk Modulus

A car enters a 300-m radius horizontal curve on a rainy day when the coefficient of static friction between its tires and the ro
Vlada [557]

To solve this problem it is necessary to take into account the concepts related to Centripetal Force and Friction Force.

In the case of the centripetal force, we know that it is defined as

F_c = \frac{mv^2}{R}

Where,

m=mass

v= velocity

r= Radius

In the case of the Force of Friction we have to,

F_f = \mu m*g

Where,

\mu =Friction Constant

m= mass

g= gravity

According to the information given, the centripetal force must be less than or equal to the friction force to stay on the road, in this way

\frac{mv^2}{R} \leq \mu m*g

Re-arrange to find the velocity,

v \leq \sqrt{\mu gR}

v \leq \sqrt{(0.6)(9.8)(300)}

v \leq 42m/s

Therefore la velocidad del carro debe ser igual o menor a 42m/s para mantenerse en el camino
