...The halogen which is LIQUID at ROOM temperature is BROMINE @[EMAIL protected]^_^

NG TO ME;;;One of the most POWERFUL laws in PHYSICS is the law of momentum conservation. The law of momentum conservation can be stated as follows.For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision. That is, the momentum lost by object 1 is equal to the momentum gained by object 2.The above STATEMENT tells us that the total momentum of a collection of objects (a system) is conserved - that is, the total amount of momentum is a constant or unchanging VALUE. This law of momentum conservation will be the focus of the remainder of Lesson 2. To understand the BASIS of momentum conservation, let's begin with a short logical proof.

n is incomplete, it would be possible LIKE The potential energy of a particle of mass 100g moving ALONG x AXIS is U=5x(x-4), where x is in metres. What is the period of oscillation?  Ans. F=-dU/dx, GIVEN U=5x(x-4)F= - 10(x-2) F= - 10XWe KNOW F= -Kx;Therefore, spring constant, K= 10.Time period, T= 2*pi*(m/k)^1/2 , where m is the mass in kg.Putting all the values , finally, T = pi/5 seconds.

ything solid turns into a gas without first becoming liquid, that'ssublimation. When the surface layer of SNOW or ice turns into fog or steam without MELTING, this is an EXAMPLE ofsublimation. The verb sublimation is from the Latin word sublimare,meaning “RAISED to a higher status.” follow me

ntal quantities are those physical quantities that cannot be expressed in terms other quantities. It is an independent quantities. For example: Length, mass, TIME, temperature, electric CURRENT, AMOUNT of substance. Derived quantities are those physical quantities that are derived from the combination of FUNDAMENTAL quantities. It is a DEPENDENT quantity. For example : force, density, volume, momentum etc.hope this help you

nt MAGNETS require special MANUFACTURING techniques in a magnetic FIELD to get the metal to stay in the proper alignment. In order to demagnetize a magnet, you need to CHANGE this alignment. This process usually requires a high amount of heat, or a strong magnetic field at a reverse POLARITY to the magnet you want to demagnetize.

is an acronym for light amplification by stimulated emission of radiation. A laseris created when the electrons in atoms in special glasses, CRYSTALS, or gases absorb ENERGY from an ELECTRICAL current or another laser and BECOME “excited.” ...

TE !!!HOPE THIS HELPS YOU...The objects which TWINKLE either in the earth's atmosphere or outside the earth's atmosphere are the objects called luminous objects. They GLOW either by producing their own light or by absorbing the light radiation from other luminous objects like moon absorb light from sun. If the object is unable to glow then they are non luminous, MEANS cannot absorb or produce own light.To glow this property is required, but since it is ABSENT in Planets they won't glow.THANK YOU FOR THE WONDERFUL QUESTION...#bebrainly

s THIRD law of planetary MOTION states thatthe cube of the mean DISTANCE of a planet from the SUN is proportional to the square of its ORBITAL period T. or,r³/T² = constant

of FIELD lines is DIRECTLY proportional to the current passing through the conductor, so the MAGNETIC field lines will GET denser when more current is PASSED through the conductor.

ear FRIEND,Causes. Materials are made of atoms that are normally electrically neutral because they contain equal numbers of positive charges (protons in their NUCLEI) and negative charges (ELECTRONS in "shells" surrounding the nucleus). The PHENOMENON of static electricity requires a separation of positive and negative charges.

gen atom is an atom of the chemical ELEMENT hydrogen. The electrically NEUTRAL atom contains a single positively charged proton and a single negatively charged electron BOUND to the nucleus by the Coulomb force. Atomic hydrogen CONSTITUTES about 75% of the baryonic mass of the universe.

ld USE a SMOOTH SURFACE like MIRROR .as mirror surface is smooth there is no roughness in the surface and than reflection ray will be EQUAL to incidence ray and light will travels straight.

vie theatre, REFLECTION of SOUND isn't really desirable. Hence sound boards and foams that absorb REFLECTED sound are INSTALLED on the walls.

e the height of the building and t be the time to fall through this height H. Then H = ½ g t^2 = 5 t^2. -- (1) In (t-1) SECOND the distance traveled is 1 - 0.36 H = 0.64 H. 0.64 H = 5 (t-1)^2.------(2) on doing  (2) / (1)we GET     0.64 = (t-1)^2/ t^2 Or 0.8 = (t-1) / t Solving we get t= 5 second. Using (1) we get H = 125 m

ruder OBSERVED Gerrard for some days and when he was FAMILIAR with the WAY he use to do stuff, he broke into his to murder him but before he would do that he ASKED Gerrard some questions about him to know him MUCH better. hope it helps

is TUNGSTEN used exclusively for the filaments of electric lamp?ANS => The melting point and resistivity of tungsten are very HIGH. It does not BURN readily at a high temperature. The electric lamps glow at very high temperatures. Hence, tungsten is mainly used as heating element of electric BULBS.
