Answer:

The TENDENCY of an object to resist changes in its state of motion varies with MASS. Massis that quantity that is SOLELY DEPENDENT upon the inertia of an object. The more inertia that an object has, the more massthat it has. A more massive object has a greater tendency to resist changes in its state of motion.

Hey MATE ,

Acceleration DUE to the earth's gravity is zero at the CENTRE of the Earth because at that point the mass of the earth is equally distributed in all directions, so pulling equally in all directions for a net zero pull. As the distance from the centre decreases, the acceleration due to gravity ALSO decreases.

INTENSE pulsed light (IPL) is a TECHNOLOGY used by cosmetic and medical practitioners to perform various skin treatments for aesthetic and therapeutic purposes, including hair removal, photorejuvenation (e.g. the TREATMENT of skin pigmentation, sun damage, and thread VEINS) as well as to alleviate dermatologic diseases such as acne.[1][2][3][4][citation needed] IPL is increasingly used in optometry and ophthalmology as well, to treat evaporative dry EYE disease due to meibomian gland dysfunction.

ANSWER:

TIME OF FLIGHT = 10s

Explanation:

u=49 m/s

v=0

g= -9.8 m/s

2gh=v^2-u^2

2*-9.8*h=-2401

h=122.5 m

v=u+gt

0=49+(-9.8)t

-49=-9.8t

t=5 sec

So TOTAL time=5+5=10 sec

HOPE IT HELPS

HEY mate ,

When we find refractive index in respect to air it is called as Absolute Refractive Index

= C/V

= speed of light in medium / speed of light in VACCUM

= 2×10^8 / 3×10

= 2×10^7 / 3

Thus Absolute Refractive Index to glass is 2×10^7/3

Hope you find it HELPFUL!!!

Answer:

When she stretches her HAND outward, her moment of inertia INCREASES and hence angular speed decreases to conserve angular momentum. When she folded her hands and brings the stretched LEGS close to the other leg, her moment of inertia decreases and hence her angular speed increases.

ANSWER:

5pts is the answer of your QUESTION

EXPLANATION:

u=16 m/s, mass=200kg

v=20m/s

momentum =mass×velocity

p=mv

p=200kg ×16m/s

=3200kg/m/s

Answer:

As the medium expands the refractive index of the medium DECREASES and THUS speed of LIGHT increases in the medium. With increase in temperature the speed of light in a medium increases maybe because of the increase in intermolecular state of the substance

Answer:

First of all, I didn't understand your question....anyways TRIED my best to inform all i can about the conservative forces.

1. If work done by a force only depends upon the initial and final POSITION of the body and not on the path by which the work was done than the force is called a conservative force. For example: GRAVITATIONAL force. If we climb 3floors or choose an elevator to the third floor, the work done against the gravitational force is the same in both the cases as the initial and final position are same.

2. POTENTIAL energy is defined only for the conservative forces. Non- Conservative forces do not have potential energy defined.

3. Work done by a conservative force is also equal to the change in potential energy ( work-energy theorem.)

Plant reproductive SYSTEM, any of the systems, SEXUAL or asexual, by which plants reproduce. In plants, as in animals, the end result of reproduction is the continuation of a given SPECIES, and the ability to reproduce is, therefore, RATHER conservative, or given to only moderate change, during EVOLUTION.

They are connected in PARALLEL. The reason for the parallel CONNECTION is that it results in each appliance OPERATING at the same voltage (i.e., approximately 120V for line-neutral connected appliances, and 240V for appliances that are connected line-line) ALONG the entire circuit.

Answer:

QUANTUM entanglement is the name given to a special connection between pairs or groups of quantum SYSTEMS, or any OBJECTS described by quantum mechanics. Quantum entanglement is one of the biggest parts of quantum mechanics that makes it hard to UNDERSTAND in terms of the everyday world.

Quantum entanglement has applications in the emerging technologies of quantum computing and quantum cryptography, and has been used to realize quantum teleportation experimentally. At the same time, it prompts some of the more philosophically oriented DISCUSSIONS concerning quantum theory.

Entanglement occurs when a pair of particles, such as photons, interact physically. A laser beam fired through a certain type of crystal can cause individual photons to be split into pairs of entangled photons. ... When observed, Photon A takes on an up-spin state.

Quantum entanglement is known to be the exchange of quantum information between two particles at a distance, while quantum superposition is known to be the uncertainty of a particle (or particles) being in several states at once (which could also involve the exchange of quantum information

Answer:

40 N

Explanation:

Hey mate,

P= FX V

here, P = 2000W

v = 180 km/ hr = 50 m/sec

therefore SUBSTITUTING the values in the formula we get,

2000 = 50 X F

therefore,

F = 40 W.

Effort refers to force only in this case...

ANSWER:

it will BREAK when TORQUE is MAXIMUM

 Moment of inertia of a body about a given axis is rhe sum of the products of masses of all the particles of the body and squares of their respective perpendicular distances from the axis of rotation.

The value of I DEPENDS upon:

1. position of axis of rotation  
2. orientation of the axis of rotation  shape of the body
3. size of the body  
4. distribution of the MASS of the body about the axis of rotation.  

When the body does not consist of discrete particles, and has a continuous UNIFORM distribution of mass, the summation in above equation can be replaced by integration,

where dm is the mass of a small element of the body at a perpendicular distance r from the axis of raotation.  

If is the density of the body, then the mass of the small element of volume dV is

 Units of Moment of Inertia:

As I = mass(distance)²

∴ Units of moment of inertia are KG m² or g cm².

Dimensions of moment of inertia are

A plane mirror is a flat mirror that reflects light and PRODUCES a virtual IMAGE without the interference of an inward or outward curve. Plane mirrors, which include the common BATHROOM and hallway mirrors used daily, produce a virtual image at the same magnification and distance as the OBJECT they reflect.

Explanation:

chemistry is the study of reactions that involve changes in nuclear structure. The chapter on atoms, molecules, and IONS introduced the basic idea of nuclear structure, that the nucleus of an atom is composed of protons and, with the exception of

1

1

H

, neutrons. Recall that the number of protons in the nucleus is called the atomic number (Z) of the element, and the sum of the number of protons and the number of neutrons is the mass number (A). Atoms with the same atomic number but different mass numbers are isotopes of the same element. When referring to a single type of nucleus, we often use the term nuclide and identify it by the notation

A

Z

X

, where X is the symbol for the element, A is the mass number, and Z is the atomic number (for example,

14

16

C

). Often a nuclide is referenced by the name of the element followed by a hyphen and the mass number. For example,

14

16

C

is called “carbon-14.”

Protons and neutrons, collectively called NUCLEONS, are packed together tightly in a nucleus. With a radius of about 10−15 METERS, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8

1014 grams per CUBIC centimeter. For example, water has a density of 1 gram per cubic centimeter, and iridium, one of the DENSEST elements known, has a density of 22.6 g/cm3. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters (earth’s actual radius is approximately 6.4

106 meters, 30,000 times larger). Example 1 demonstrates just how great nuclear densities can be in the natural world.
