For example, if we stand at a distance of 2 meters from a plane mirror, we must FOCUS at a location 2 meters behind the mirror in ORDER to view our image. In this case, the distance between the object and its image FORMED by a plane mirror appears to be 24 cm. So, the object distance will be 24 / 2 = 12 cm.

Explanation:the law of conservation of momentum STATES that for two or more bodies acting UPON each other, their momentum ALWAYS remains constant, therefore momentum can neither be created nor be destroyed.DERIVATION-Consider two colliding particles A and B whose masses are m1 and M2 with initial and final velocities as u1 and v1 of A and u2 and v2 of B. The time of contact between two particles is given as t. A = m1(v1 − u1) (change in momentum of particle A) B = m2(v2 − u2) (change in momentum of particle B) FBA = −FAB (from third law of motion)FBA = m2*a2 =m2(v2-u2)/tFAB = m1*A1= m1(v1-u1)/tFBA = -FABm2(v2 - u2) = -m1(v1 - u1)m2v2 - m2u2 = -m1v1 - m1u1m1v1 + m2v2 = m1u1 + m2u2

The earliest recorded systems of weights and measures originate in the 3RD or 4th millennium BC. Even the very earliest civilizations needed measurement for purposes of agriculture, construction, and trade. Early standard units might only have applied to a single community or small region, with every area developing its own standards for lengths, areas, volumes and masses. Often such systems were closely tied to ONE field of use, so that volume measures used, for example, for dry grains were unrelated to those for liquids, with neither bearing any particular relationship to units of length used for measuring cloth or land. With development of manufacturing technologies, and the growing importance of trade between communities and ultimately across the Earth, standardized weights and measures became critical. Starting in the 18th century, modernized, simplified and uniform systems of weights and measures were developed, with the fundamental units defined by ever more precise methods in the science of METROLOGY. The discovery and APPLICATION of electricity was one FACTOR motivating the development of standardized internationally applicable units.

Rectilinear propagation of light refers to the propensity of light to travel along a straight LINE without any INTERFERENCE in its trajectory. When light travels through a medium, say air or water, it follows a straight line. ... ANOTHER example of rectilinear propagation of light involves the formation of shadows.

ources of water POLLUTION are discharge of domestic and agriculture wastes, POPULATION growth, EXCESSIVE use of PESTICIDES and fertilizers and urbanization. Bacterial, viral and parasitic diseases are SPREADING through polluted water and affecting human health.❣️plz mark me as brainliest ❣️

we know VELOCITY =√2gh PUT this VALUE and find V and then KE =1/2MV^2

Because MOLECULES that are melting are absorbing HEAT, we refer to melting as an endothermic process. Endo means “to ENTER” while THERMIC means “heat.” The REVERSE of melting (liquid back to solid) is called freezing. The temperature where freezing occurs is exactly the same as the melting point.

9. Muscles use the stored chemical energy of food we EAT and convert that to heat and energy of motion (kinetic energy).2. Here are only some of your many choices for heating energy sources: natural gas, PROPANE (LP), oil, coal, wood, electricity, heat pumps, ground source heat pumps and solar energy. Radiantec strives to offer products that are highly energy efficient and yet still a smart investment.3.In PHYSICS and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over TIME. ... For instance, chemical energy is converted to kinetic energy when a stick of dynamite explodes.

The surface is plainExplanation:As the surface is PLAIN the RAYS reflect in a regular MANNER and form a CORRECT image, If it was ROUGH, then the rays diverge and hence cause blurrness of imageMark me as brainliest and follow me, I will follow u back

ce that stretches a string or SIMILAR object is CALLED Tension also refers to the elastic force transmitted through a stretched object. Tension acts along the direction of the string. ... If the tension is too great, the CABLE will BREAK. ROPES and strings are not the only objects that can have tension.

ings FEEL so tight they might snap, that's TENSION. The noun tension has its Latin roots in tendere, which means to stretch, and tension occurs when SOMETHING is stretched either physically or emotionally. Strained RELATIONS between countries can cause political tensions to rise.PLZ MARK ME AS BRAINLIEST!!!!!!!!!!!!!!

The RESPIRATORY system of tiger consists of lungs like humans and all mammals,Siberian tigers breathe through their nose and MOUTH into their lungs.when air is breathed into the lungs it ABSORBS all the oxygen and exhales the carbon dioxide Explanation:Hope u understand pls support me by rating my answer.And pls mark me as the brainliest.And pls follow me and if any DOUBT in the answer pls COMMENT.

stretch means to expand LIKE if you expand a RUBBER BAND it will called stretchbut but when you are trying to remove the water from wet CLOTH after washing it is squeeze

You can MAKE an electromagnet stronger by doing these THINGS: WRAPPING the coil AROUND a piece of IRON (such as an iron nail) adding more turns to the coil. increasing the current flowing through the coil.

tion:Underneath the blade of figure skates, there is a THIN layer of water from the MELTED ice. When the blades of the skates GLIDE over the ice, there is HEAT generated causing the ice to melt. ... This water then acts as a lubricant (something WHOSE purpose is decreasing friction), resulting in smooth motion over the ice.

tion:2). The light is absorbed inside the object.3). It can be used as a SOURCE of lighting in dark PLACES, where you WANT a little decoration

cence has many PRACTICAL APPLICATIONS, including mineralogy, gemology, MEDICINE, chemical sensors (fluorescence SPECTROSCOPY), fluorescent labelling, DYES, biological detectors, cosmic-ray detection, vacuum fluorescent displays, and cathode-ray tubes.

The magnetic effect of ELECTRIC current is KNOWN AD electromagnetic effect. It is observed that when a compass is brought near current carrying CONDUCTOR the needle of compass gets DEFECTED because of flow of electricity. Explanation: They are used to remove iron particles from wound.They are used to concentration of ores using electromagnetic sepration..

s a push or pull upon an object resulting from the object's interaction with ANOTHER object. Whenever there is an interaction between TWO objects, there is a force upon each of the objects. When the interaction ceases, the two objects no LONGER experience the force. Explanation:Force can produce these CHANGES---1) Stop a body2) Give acceleration to a BODY, i.e. moving a body3) Change direction of motiin of moving body4) Deform/reform a body.

re suggested, a magnetic field is PRODUCED whenever an electrical CHARGE is in motion. The spinning and orbiting of the nucleus of an ATOM produces a magnetic field as does electrical CURRENT flowing through a wire. The direction of the spin and orbit determine the direction of the magnetic field.HOPE IT HELPS U!!!
