Moseley's Law describes the relationship between atomic NUMBER and frequency of a spectral line of characteristic X-rays. When the square ROOT of the frequencies of the characteristic X-rays from the ELEMENTS is plotted against the atomic number, a STRAIGHT line is obtained FOLLOWING the equation:ν =a(Z−b). So, this will never touch the origin.

fastExplanation:Keplar's third law SUGGESTS that the square of orbital period of a planet is directly proportional to the cube of the semi-major of its ORBITS, thus capturing the relation between the distance of PLANETS from the sun, and their orbital periods.Thus when the planet comes NEAR to the sun, it moves FASTER.

ective RESISTANCE is 6.67 OHMS

hii I think that it HELPS youExplanation:electromagnetic wave has a FREQUENCY and a wavelength ASSOCIATED with it and travels at the speed of LIGHT, or c. The relationship among these wave characteristics can be described by vW = fλ, where vW is the propagation speed of the wave, f is the frequency, and λ is the wavelength. Here vW = c, so that for all electromagnetic waves, c = fλ.Thus, for all electromagnetic waves, the GREATER the frequency, the smaller the wavelength.

8/3 In the above arrangement we FIND that R1/R2=R3/R4so 7 OHM resistance will be short circuitedSo 2 ohm and 4 ohm are in parallel.And EQUIVALENT 2ohm and 4 ohm are in series with each other. THEREFORE the equivalent will be 8/3 ohm

Reflux is a technique involving the condensation of vapors and the RETURN of this condensate to the system from which it ORIGINATED. It is used in INDUSTRIAL and LABORATORY distillations. It is also used in chemistry to supply energy to reactions over a long period of time.

A surface built from a non-absorbing powder such as plaster, or from fibers such as paper, or from a polycrystalline MATERIAL such as white MARBLE, reflects light diffusely with great efficiency. Many common materials EXHIBIT a mixture of specular and diffuse reflection.

A.Amplitude, in physics, the maximum displacement or distance MOVED by a point on a vibrating body or wave measured from its EQUILIBRIUM position. ... The amplitude of a pendulum is thus one-half the distance that the bob traverses in moving from one side to the other.b.Frequency, , is defined as the RATE of rotation, or the number of rotations in some unit of time. Angular frequency, , is the rotation rate measured in radians.c.Velocity is defined as the ratio of net displacementand time TAKEN . It is a vector QUANTITY and its direction is in the direction of net displacement. if displacement is zero(intial and final position is same) then itsvelocity is zero.Explanation:mainne ise googlai se kopee kiya haihope u understand......Hope it will help you ☆☆☆

YOUR ANSWER IS HERE Explanation:DEFINATION OF VECTOR ACCORDING TO CLASS 11THVECTOR :-Those physical quantities which require magnitude as well as DIRECTION for their complete representation and follows vector laws are called vectorsVector can be divided into two types 1. Polar Vectors These are those vectors which have a starting point or a point of application as a displacement, force etc. 2. Axial Vectors These are those vectors which represent rotational effect and act along the axis of rotation in accordance with right HAND screw rule as angular velocity, torque, angular momentum etc.MAY HOPE THIS IS HELPFULL TO YOU AND OTHERS

c CURRENT is a scalar quantity. Any physical quantity is TERMED as a vector quantity when the quantity has MAGNITUDE and direction. hence ANSWER is current

currentvoltage characteristic or IV curve (currentvoltage curve) is a relationship, typically represented as a chart or graph, between the electric current through a circuit, device, or MATERIAL, and the corresponding voltage, or potential difference across it.In the graph, the voltage is plotted along the y-axis and the current is plotted along the x-axis. In the given EXAMPLE, the current I against the potential difference V, is a straight line with CONSTANT slope 1/R as the relation is linear and ohmic. That is, the remains constant for varying values of voltage and current.The resistance can be found USING the OHM's law which states R=V/I=0.5/0.2 or1.0/0.4, etc will give 2.5 ohms.Hence, the resistance is 2.5 ohms.solution

Force per unit length between two long straight parallel conductors: Suppose two long thin straight conductors (or wires) PQ and RS are placed parallel to each other in vacuum (or air) carrying currents I1 and I2 respectively. It has been observed experimentally that when the currents in the wire are in the same direction, they experience an attractive force (fig. a) and when they carry currents in opposite directions, they experience a repulsive force (fig. b). Let the conductors PQ and RS carry currents I1 and I2 in same direction and placed at SEPARATION rConsider a CURRENT–element ‘AB’ of length ΔL of wire RS. The magnetic field produced by current-carrying conductor PQ at the location of other wire RSAccording to Maxwell’s right HAND rule or right hand palm rule no. 1, the direction of B1 will be perpendicular to the plane of paper and directed DOWNWARD. Due to this magnetic field, each element of other wire experiences a force. The direction of current element is perpendicular to the magnetic field; therefore the magnetic force on

Periodic motion, in PHYSICS, motion repeated in equal intervals of time. Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a SWING in motion, the Earth in its orbit around the Sun, and a water WAVE. In each case the interval of time for a repetition, or CYCLE, of the motion is called a period, while the number of periods per unit time is called the frequency. Thus, the period of the Earth’s orbit is one YEAR, and its frequency is one orbit per year. A tuning fork might have a frequency of 1,000 cycles per second and a period of 1 millisecond (1 thousandth of a second).

Initial velocity ( u ) = 100 cm / sec. Retardation ( - a ) = - 5cm / sec^2. { Retardation means negative acceleration } Time ( t ) = 15 sec. Final velocity ( V ) = ? So, we KNOW from the formula, Acceleration = (Final velocity - Initial velocity)÷ Time.i.e. a = ( v- u ) / t . -5 = ( v - 100 ) / 15 -5 × 15 = v- 100. { transposing 15 to LHS } - 75 = v - 100. -75 + 100 = v { transposing -100 to LHS } v = 25 cm/sec. Therefore , 'v' i.e. final velocity = 25cm/sec.Now, we NEED to find the time at which the body comes to rest. Here, u = 25 cm/sec. { because the body is now going to be at rest , hence the final velocity becomes the initial velocity } v = 0 cm / sec . { the body is at rest , hence no movement } . acceleration = -5cm / sec^2. Again , from the formula, a = ( v - u ) / t -5 = ( 0 - 25 ) / t. -5 = -25 / t. -5T = -25 t = -25 / -5. t = 5 sec. Hence , the body will come at rest in 5 seconds.
