the electric displacement, also known as dielectric displacement and usually DENOTED by its FIRST letter D, is a VECTOR field in a non-conducting medium, a dielectric. The displacement D is PROPORTIONAL to an external electric field E in which the dielectric is placed.Explanation:follow me ♥♥

Answer. It does ROTATIONAL work. We can view this work as a medium between gravitational POTENTIAL energy and rotational kinetic energy. So when it accelerates down the incline, FRICTION FORCE takes some of the gravitational potential energy and turns it into rotational kinetic energy for the CYLINDER.

Here!!!EXPLANATION:Single TOUCH method :- This is one of the most various ways of MAKING a MAGNETIC material like soft iron PEICE that rubbed over a sheet of magnet

Clinical thermometer-Clinical thermometer-Their MAIN DISADVANTAGE is that they are fairly EASY to break and if they do, it results in small splinters of glass and the release of mercury which is quite toxic if absorbed into the body.Clinical thermometer-Their main disadvantage is that they are fairly easy to break and if they do, it results in small splinters of glass and the release of mercury which is quite toxic if absorbed into the body.Laboratory thermometer-Clinical thermometer-Their main disadvantage is that they are fairly easy to break and if they do, it results in small splinters of glass and the release of mercury which is quite toxic if absorbed into the body.Laboratory thermometer-There are some disadvantages USING the lab thermometer in the body. when you take it out for MEASURING, the mercury drops down because there is no kink. a laboratory thermometer does kink.

A 20-kg mass of IRON at 100°C is BROUGHT into contact witn 20 kg of aluminum at 200°C in an insulated enclosure. Determine the final EQUILIBRIUM TEMPERATURE of the combined system.

An object can store energy as the RESULT of its position. For example, the heavy ball of a demolition MACHINE is storing energy when it is HELD at an elevated position. Explanation:Hope this answer is helpful to u and GIVE me thanks and take thanks please FOLLOW also

direction of umbrella should be toward the RAIN in South direction and RELATIVE velocity of rain is 20m/s

A bullet --- 200m/s It moves to 4 cm the velocity is -- 200 ÷ 10 = 20 20 × 4 = 80 so , the velocity is 80 m/s I THINK IT WILL HELPFUL FOR YOU

The AVERAGE density of an object is what ULTIMATELY determines whether it floats. If an object's average density is LESS than that of the surrounding FLUID, it will float. The reason is that the fluid, having a higher density, contains more mass and hence more WEIGHT in the same volume.

here is ur ANSWER Explanation: ( i )ma = load / effort =4T/T= 4. mechanical ADVANTAGE of the given pulley system is 4.( II ) VR = 4, load = 4T , Effort = T

The diagram below illustrates the LAW of REFLECTION. In the diagram, the ray of light approaching the mirror is known as the incident ray (LABELED I in the diagram). ... The law of reflection states that when a ray of light reflects off a surface, the ANGLE of INCIDENCE is equal to the angle of reflection.Hope this help you

A SOFT metal core MADE into a magnet by the PASSAGE of electric CURRENT through a coil surrounding it.Hope it helps ❤️❤️Explanation:

am SRY i DONT KNOW the ANSWER

Assuming that your unknown substance is a liquid.Specific gravity is the density ratio of the material to that of a REFERENCE. For liquids the specific gravity is the ratio of the density of the unknown liquid to that of water. So this way we can find the density of the particular substance which is ASSUMED here to be a liquid by multiplying 0. 79 with density of water which is 1000kg/m^3.So the density of the unknown fluid is 790kg/m^3.The specific weight is the density times the acceleration due to gravity. Here it's 790 times 9.81 which is 7749.9N/m^3.HOPE IT WILL HELP U ✌

tion:Tension USUALLY arises in the use of cables, ROPE to TRANSMIT a force. Let's consider a block being pulled by a rope. The person pulling at ONE end of the rope is not in contact with the block in the other end and cannot exert the DIRECT force on the block.

An ELECTROMAGNET is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire CREATES a magnetic field which is concentrated in the hole, DENOTING the CENTER of the coil.Explanation:It will be HELPFUL to you

The LAW can be derived from the kinetic THEORY of gases assuming a perfect (ideal) gas (see perfect gas). Real gases obey Boyle’s law at sufficiently low PRESSURES, ALTHOUGH the PRODUCT pv generally decreases slightly at higher pressures, where the gas begins to depart from ideal behaviour.

Quantum numbers are important because they can be USED to determine the electron configuration of an atom and the probable LOCATION of the atom's ELECTRONS. Quantum numbers are also used to understand other characteristics of ATOMS, such as ionization energy and the atomic radius.Explanation:Hope this answer is helpful to u and give me thanks and take thanks PLEASE follow also

Artificial MAGNETS are preferred over natural magnets because natural magnets are weak and often irregular in shape, they can readily be MAGNETIZED and demagnetized by tuning the CURRENT on or off in the coilExplanation:Hope this will help you

Gravity acts on airplane like it acts on any other object. This is why PLANES also have WEIGHT. DUE to pressure difference across the wing, airplane experience a net upward force called Lift (force) - Wikipedia which balances the weight of airplane and keeps the plane afloat.

As we know that the acceleration in earth is calculated by the FORMULA (Gm)/(r^2) which EQUALS 9.8m/s^2 where m is the MASS of the earth and r is the RADIUS of the earth. so, the value of g on that PLANET will be 19.6m/s^2.

By observing the MOTION of objects on an INCLINED plane Galileo DEDUCED that objects move with a constant SPEED when no force ACTS on them. He observed that when a marble rolls down an inclined plane, its velocity increases
