Velocity of an OBJECT is said to be uniform when its SPEED and direction does not change . The object at rest has uniform speed of zero all the TIME and does not EVEN change the direction . Hence, the velocity of an object rest is considered to be uniform .PLZ mark me as brilliant please please

The molecular mass is the mass of a given molecule: it is measured in daltons. Different MOLECULES of the same compound MAY have different molecular MASSES because they contain different isotopes of an ELEMENT.

Parting, in metallurgy, the separation of gold and silver by chemical or electrochemical means. Gold and silver are often EXTRACTED together from the same ores or RECOVERED as by-products from the extraction of other METALS. A solid mixture of the two, known as bullion, or doré, can be parted by BOILING in nitric ACID.

cess of something abstract ceasing to exist.Evaporation is a type of VAPORIZATION that occurs on the SURFACE of a LIQUID as it changes into the GAS phase. The surrounding gas must not be saturated with the evaporating substance. When the molecules of the liquid collide, they transfer energy to each other based on how they collide with each other.

why???????????????????????

tion:According to Moseley, similar properties recur periodically when elements are arranged according to increasing atomic number. Atomic numbers, not weights, determine the factor of chemical properties. MENDELEEV ORDERED his elements in order of their RELATIVE atomic mass, and this gave him some problems.ᕼOᑭᗴ IT ᕼᗴᒪᑭՏ YOᑌ✌️

Monera (/məˈnɪərə/) (GREEK - μονήρης (monḗrēs), "single", "solitary") is a kingdom that CONTAINS unicellular ORGANISMS with a prokaryotic cell organization (having no NUCLEAR membrane), such as bacteria. They are single-celled organisms with no true nuclear membrane (prokaryotic organisms).

Density, MASS of a unit VOLUME of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of GRAMS per cubic centimetre. ... For example, the density of AIR is 1.2 kilograms per cubic METRE.

we measure HEAT ?Measurement of heat is done in calories. One calorie is the amount of energy required to raise one gram of water one degree Celsius. To measure heat, you divide the change in TEMPERATURE of a sample of water by the mass of the water.What is used to measure heat ?Two classes of instruments are EMPLOYED for the measurement of heat, namely, thermometers and pyrometers. Thermometers are only employed to measure COMPARATIVELY low temperatures, and we shall confine our remarks entirely to this class in the present article.hope it helps !!

ReproductionReproduction is a characteristic of all living systems; because no INDIVIDUAL organism lives FOREVER, REPRODUCTION is essential to the continuation of every SPECIES. Some organisms reproduce asexually.

bullet=10g=0.01kgvelocity of bullet=1.5 sm mass of PLANK=90g=0.09kgTotal momentum before COLLISION=mass of plank × VELOCITY=0.01×1.5+0.09×0=0.015kg sm Total momentum after collision=(mass of bullet +mass of plank )× velocity=0.1kg×V=0.1Vkg sm According to law of CONSERVATION of momentum,Total momentum before collision=Total momentum after collision0.015kg sm =0.1vkg sm velocity ACQUIRED by the plank and the bullet=0.15 sm

q ′ = R 2 GM = (4ve) 2 G×2me = 81 ve 2 Gme = 8G To find 4 times the ACCELERATION due to gravity =4× 81 g= 2g = 210 =5m/s 2 Hence, the ANSWER is 5m/s 2 .

ics 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.

Mass m = 7.5 × 10^(-4) KG Time t = 0.5 sec LENGTH l = 0.1 m = 10 cm Explanation: 1 dyne = 1×10^(-5) N 1 dyne = 1×10^(-5) Kgm/sec 1 cm/sec^(2) = 0.01 m/sec^(2) # Force; F = ma > a = F/m > a = [30×10^(-5)] / [40×(0.01)] > a = [30×10^(-5)] / [0.4] > a = 7.5×10^(-4) # Time; v = at > t = v/a > t = (20×0.01) / (40×0.01) > t = 0.5 sec # Length; l = vt > l = (20×0.01) × 0.5 > l = 0.1 m = 10 cm HOPE YOU LIKE MY SIMPLEST WAYExplanation:

A compound is a substance formed when two or more chemical elements are chemically BONDED TOGETHER. ... Example 1: Pure water is a compound MADE from two elements - hydrogen and OXYGEN. The ratio of hydrogen to oxygen in water is always 2:1. Each molecule of water contains two hydrogen ATOMS bonded to a single oxygen atom.

Metallic oxides are basic in nature because they react with DILUTE acids to form salt and water. ... On the other hand, non metal oxides react with water to form acidic solutions which LIBERATE H+ IONS in SOLUTION. Thereforenon metallic oxides are acidic in nature.Explanation:PLS MARK AS BRAINLIEST

Because the longer the spanner is , the more is the PERPENDICULAR distance between the axis of spanner through which it rotates and the distance of your hand. And when perpendicular distance is more, less FORCE is required. Try using the spanner by holding it with UR hand KEPT near the nut.

Solution. When an object falls freely to the GROUND, it is under the effect of a constant force KNOWN as force of gravity. No other forces ACT on it. Hence, from Newton's second law of motion, we can say that this constant force of gravity accelerates the thefreely falling object uniformly.Explanation:PLS MARK AS BRAINLIEST

what is the QUESTION??

A measurement NEEDS both a number and a unit for complete SPECIFICATION because : If we just say 6, the other person will not understand what we mean; HENCE we have to use a unit of length. If we just say metres, the person will wonder how many metres; therefore we have to tell the number to EXPRESS the right QUANTITY.
