The CURRENT DENSITY is the amount of charge per UNIT.

yes , they are not ALLOWING us to se ANSWERSWHAT's the NONSENSE

The MOMENT of INERTIA DEPENDS on the following FACTORS .The density of the material ,shape and size of the body .Axis of rotation (distribution of mass RELATIVE to the axis)

A , OPTION is CORRECT ANSWER

Besides pressure, denoted in equations as P, GASES have other measurable properties: temperature (T), volume (V) and NUMBER of PARTICLES, which is expressed in a mole number (n or mol). In work INVOLVING gas temperature, the Kelvin scale is often used.Explanation:PLEASE mark as brainlist and follow me

tion:On one end of the electromagnetic spectrum are radio WAVES, which have wavelengths billions of TIMES LONGER than those of visible light. On the other end of the spectrum are gamma RAYS, with wavelengths billions of times SMALLER than those of visible light.

ne : It is defined as work done by the BODY as the FORCE exerted on the body along the direction of displacement . In mathematical FORM , it is represented as ,➳ W = F × s × cosθSI UNIT : JouleForce exerted (F) = 15 NDisplacement (s) = 2 mDisplacement is in opposite direction of applied force , so ⇒  θ = 180° ____________________________➠ W = F × s × cos 180➠ W = 15 × 2 × (-1)➠ W = 30 × (-1)➠ W = - 30 N

An example of to TRANSFER is the owner of a car signing the title over to a new owner. An example of to transfer is PICKING up a package from one location and bringing it to ANOTHER. (COUNTABLE) An INSTANCE of conveying or removing from one place, person or thing to another; a transferal.

:Initial VELOCITY = zeroFinal velocity = 40 km/hTime of journey = 1 minuteWe have to find acceleration of the train★ Acceleration is defined as the rate of CHANGE of velocity.Mathematically, a = v - u / ta denotes accelerationv denotes final velocityu denotes initial velocityt denotes timeIt is a vector quantity having both magnitude as well as direction.It can be POSITIVE, negative or zero.SI unit : m/s²★ Conversion :• 1 km/h = 5/18 m/s• 40 km/h = 40 × 5/18 = 11.11 m/sTime : 1 min = 60 s➝ a = v - u / t➝ a = 11.11 - 0 / 60➝ a = 11.11/60➝ a = 0.18 m/s²

56answer,,,,,,,,,,,,,,,,,

Acceleration as a VectorAcceleration is THEREFORE a CHANGE in either speed or direction, or both. Keep in mind that although acceleration is in the direction of the change in velocity, it is not always in the direction of MOTION. When an object slows down, its acceleration is OPPOSITE to the direction of its motion.

See, if the refractive INDEX in medium is 3/2 the as we know that:refractive index of a medium with respect to AIR = reciprocal of the refractive index of air with respect to the medium.so, the refractive index of air is 2/3 .Now, we know that any matter or substance whose refractive index is higher, it's speed is low. So, in this QUESTION we can GUESS that speed of light is less that 2/3.

:Two FORCES of 3N and 4N act at right angles on a block.Acceleration of block = 7m/s²We have to find mass of block★ First of all we need to find net force acts on the block. If two forces A and B act at right angles on a BODY then resultant force R is given byR² = A² + B²By substituting the values,➝ R² = A² + B²➝ R² = 3² + 4²➝ R = √25➝ R = 5N★ As per newton's second law of motion, force is measured as the product of mass and acceleration. F = m a➝ F = m a➝ 5 = m × 7➝ m = 5/7➝ m = 0.71 kg

and is C. EXPLANATION:this is my THINKING

The duration will increase drastically to 96 HoursExplainations:Here, D2=2D1(Because earth has expanded TWICE)∴R2=2R1(Because earth has expanded twice)T1=1day=24hr,T2=? ACCORDING to the LAW of conservation of ANGULAR MOMENTUM, I2ω2=I1ω1 25mR22(2πT2)=25mR21(2πT1) T2=T1(R2R1)2=24(2)2=96hours

When a ray of light passes from a less dense material (eg air) into a DENSER material (eg glass or water) it is bent AWAY from the surface between the TWO materials. This means that in this situation the ANGLE of refraction is ALWAYS less than the angle of incidence.

exerted by TWO OBJECTS on each other are OFTEN called an action- reaction force PAIR. ... However, action and reaction force pairs don't cancel because they act on different objects. Forces can cancel only if they act on the same object.

h = 80 m,  v = 40 m/sExplanation:Givena stone is dropped from the top of the cliffTime taken for stone to reach the ground = 4sLet height be 'h' and final velocity be 'v'a = G = 10m/s²As it is a freely falling body initial velocity is zero i.e., U = 0.We know thats = ut + 1/2 at²⇒h = ut + 1/2 at²     [ here DISPLACEMENT of stone is height of the cliff]⇒h = 0 + 1/2 10*(4)²∴ h = 5*16 = 80 m∴ h = 80 mWe know thatv = u + at⇒v = 0 + 10*4∴v = 40 m/s

❤Solenoid is the generic term for a coil of wire used as an electromagnet. It also refers to any device that converts ELECTRICAL energy to mechanical energy USING a solenoid. The device creates a magnetic field from ELECTRIC current and uses the magnetic field to create LINEAR motion.Hope its HELP u ❤
