Why is chemical energy a form of potential energy

For every action there is an equal and opposite reaction. What does these words mean in physics?

Ne4ueva [31]

Answer:

The above given statement represent the Newton;'s 3rd law of motion.

This describes that when two objects collides or interacts with each other, there occurs a pair of forces that directly acts on the two colliding objects. The force exerted on both the sides are of equal magnitude.

For example, there are two contrasting body named M and N, which collides with each other. This collision results in the occurrence of force acting on both the objects. The body M exerts a force on body N and similarly, the body N exerts a force on body M, and this two forces are equal in amount.

A forest ranger might be ranked as being high in what type of intelligence?

Drupady [299]

<h2>Answer:</h2>

<u>A forest ranger might be ranked as being high in </u><u>Naturalistic</u><u> intelligence.</u>

<h2>Explanation:</h2>

Naturalistic intelligence is the type of intelligence that relates the activities of people that how sensitive an individual is to nature and the world. Zookeepers, biologists, gardeners, and veterinarians are among those people who have a higher capability of having high naturalist intelligence. Similarly a ranger who is fighting in forests must also be kept in the same category and he might be ranked as being high in the field of Naturalistic Intelligence.

Construct vectors A and B for the cases below. First draw a vector W, then the parallelogram that has equal and opposite vector

gregori [183]

Answer:

Diagrams containing answers are attached

Explanation:

Diagram needed to solve the question was missing, So I have attached it with this answer. Also the diagonals of a parallelogram can only be equal to A + B (Not AB as given in your statement).

~~~~~~~~~~~~~~~~~~~~~~~ ANSWER FROM HERE ~~~~~~~~~~~~~~~~~~~~~~

First of all let us understand the law of parallelogram for vector addition. It states that, <em>"If two vectors are along the adjacent sides of a parallelogram, then their resultant is given by the vector that is a diagonal passing through the point of contact of these vectors".</em>

I have attached the diagrams describing the vectors A and B for the cases.

From diagram, it is clear that the magnitude of A and B is equal (balancing horizontal forces) and the resultant A + B is equal to the weight of the stone W (balancing vertical forces). Therefore, we can mathematically write:

A = B - - - - - (i)

& A + B = W - - - - - - (ii)

Putting A = B in equation (ii), we get

B + B = W

2B = W

Putting B = W/2 in equation (i), we get

Hence, magnitudes of both A and B are approximately W/2

An oil film on top of water has one patch that is much thinner than the wavelength of visible light. The index of refraction of

GenaCL600 [577]

Answer:

they indicate that the thickness is much less than the length of anything we have a destructive interference, bone has a dark area

Explanation:

Let's analyze the interaction of the ray reflected on the surface of the oil and at the bottom of the film, to know what kind of interference we have.

- When the beam passes from the air to the oil film, it has a phase change of 180 since the refractive index of the oil is greater than the refractive index of the air n = 1

- When the beam reaches the oil-water interface, the refractive impact of the water is oil cobs, therefore it has a 180 phase change

- in the oil film because the speed of the beam is different from that of air and the frequency in the air and oil is the same, since the propagation of a resonant type process, to meet the equation

v = λ f

The wavelength must change c = λ₀ f

c / v = λ₀ /λ

n = λ₀ /λ

λₙ = λ₀ / n

In general this type of reflection is almost normal to the surface, so we can calculate the optical path difference, if t is the thickness of the film, for constructive interference

2t = m λₙ + λₙ / 2 + λₙ / 2

The last two terms are for the phase change

2t / = (m + 1) λₙ

This is the condition to see a bright beam

For the first reflection m = 0

2t = λₙ

Therefore the minimum thickness of the film for constructive interference is λₙ / 2.

As they indicate that the thickness is much less than the length of anything we have a destructive interference, bone has a dark area
