Answer:

Paramagnetic materials include magnesium, molybdenum, LITHIUM and tantalum. Unlike ferromagnets, paramagnets do not retain any magnetization in the absence of an externally applied magnetic field, because thermal motion randomizes the spin ORIENTATIONS responsible for magnetism.

Explanation:

Only a CONVERGING lens can be used to produce a REAL image; and this only occurs if the object is located at a POSITION of more than ONE focal length from the lens. 2. ... A converging lens will only produce a virtual image if the object is located in front of the focal point.

Answer:

Coulomb's LAW explains the ELECTROSTATIC force at a given distance squared. It's STATED as: Force = (k) x (e1) x (e2) / r^2. The real source of Coulomb's law is the creation of an electron 'charge' in accordance with E = M x C^2.

The FIVE KINGDOM classification was DISCOVERED by R. H. Whittaker in 1969.

Answer:

The ELECTRIC dipole moment is a measure of the separation of positive and negative electrical CHARGES within a system, that is, a measure of the system's overall polarity. The SI units for electric dipole moment are coulomb-meter; however, a commonly used UNIT in atomic physics and CHEMISTRY is the debye.

ANSWER:

The strength of the π bonding in the TRIPLY bonded dinitrogen is less than that of the σ bonding. ... The contribution of the π bonding in CO is larger (49.2%) than in N2 (34.3%). The reason why CO has a stronger BOND than N2 is the significantly weaker Pauli repulsion in CO.

ANSWER:

DEAR STUDENT here is your answer-

Answer:

a) θ = α

Explanation:

The forces acting on the mass m in both cases are

1. WEIGHT of the mass, mg which can be resolved into two components one along the plane(downward inclination) and other perpendicular to the plane.

2. Friction force, f along upward incline direction.

3. Normal reaction, N from the wedge perpendicular to the plane

The free body diagram of the mass in both cases is attached.

case 1

The mass will START to slide down just as the component of weight along the plane overcome the friction force.Hence

mgsin(θ) = f = μN

Also,

mgcos(θ) = N

Dividing the equations we get

sin(θ)/cos(θ) = μ

or tan(θ) = μ

or θ = tan⁻¹(μ) ........(1)

Case 2.

As the wedge is ACCELERATING upward with acceleration a, the mass will experience a pseudo force ma in the downward direction. This can be resolved into two components mgsin(α) and mgcos(α) similar to that of mg.

The mass will start to slide just as the components of weight and pseudo force along the plane balance the friction. Hence

mgsin(α) + masin(α) = f = μN

and

mgcos(α) + macos(α) = N

Dividing the equations, we get

sin(α)/cos(α) = μ

or tan(α) = μ

or α = tan⁻¹(μ) ...........(2)

From (1) and (2)

θ = α = tan⁻¹(μ)

This angle is known as angle of repose and is CONSTANT for a pair of surfaces.

ANSWER:

mg.sin60°

Explanation:

ANGLE between the direction of ACTING FORCE and the direction of MOTION is 60°.

• ACCORDING to given QUESTION :

Rutherford's model was UNABLE to explain the stability of an atom. According to Rutherford's postulate, electrons revolve at a very high speed AROUND a nucleus of an atom in a fixed orbit. ... Rutherford's THEORY was INCOMPLETE because it did not mention anything about the ARRANGEMENT of electrons in the orbit.

Write LAW of conservation of energy. prove that total mechanical energy is conserved for freely falling body.

<U>solution : law of conservation of energy : according to this theory, total energy is neither created nor destroyed. in short, INITIAL total energy equals to final total energy.

i.e.,

let a body of mass m is dropped from the top of tower of height h.

at height point, velocity of body, u = 0

kinetic energy = 0

potential energy = MGH

so, initial total energy = 0 + mgh = mgh ......(1)

velocity of body before reaching the ground, V = √(2gh)

so, kinetic energy = 1/2 mv² = 1/2 m(2gh) = mgh

potential energy = 0

so final kinetic energy = mgh + 0 = mgh ......(2)

from equations (1) and (2) we get,

initial total energy = final total energy

Therefore it is clear that total mechanical energy (kinetic energy + potential energy) is conserved for freely falling body.

1/f=4-1/120

1/f=3/120

3f=120

f=120/3
