what's the question❓❓

Each and every object possesses ENERGY, EITHER while MOVING or at rest. In the simple harmonic motion, the object moves to and fro along the same path. Do you think an object possesses energy while travelling the same path again and again? Yes, it is energy in simple harmonic motion. Let’s learn how to calculate this energy and UNDERSTAND its PROPERTIES.

When combining values with different degrees of precision, the precision of the FINAL answer can be no greater than the least PRECISE measurement. HOWEVER, it is a good IDEA to keep one more digit than is significant during the calculation to reduce rounding errors.

Astronomers from the European Southern Observatory (ESO) discovered thenearest black holefrom the PLANET Earth, reported the Universe today. It is located in the constellation of Telescopium (nearthe constellation of Sagittarius) just 1000 light-years away from the Earth, ADDED the report.

6 C 12 →e=6Number of protons = 6=6amuNumber of NEUTRONS = 6=6amuTotal mass = (6+6)=12amuMass of the electron is negligible.If the mass of the NEUTRON is doubled, then the TOTAL mass = (6×2)+6= 18amuTherefore, the % of the increase = = 1218−12 ×100=50%

A LIQUID which can CONDUCT ELECTRICITY is CALLED an ELECTROLYTE

okkkkkkkkkkkkkkkkkkkkkkkkkk

Pressure = [M1 L1 T-2] × [L2]-1 = M1 L-1 T -2. THEREFORE, the pressure is DIMENSIONALLY represented as M1 L-1 T -2.Explanation:please mark me brainlist☠️☠️

ct of VOLUME 40 cm and in the form of a CYLINDER is tied to the hook of a spring balance records the weight to be 125 gf. The OBJECT lowered in a LIQUID of density 0.8 GCM, such that half of it is IMMERSED in the liquid. What is the new reading on the spring balance ?New reading of the spring balance is 109 gf.Given:-Initial reading on the spring balance = 125 gfVolume of the object = 40 cmSo, volume of the object immersed in liquid = 40/2 = 20 cmVolume of the liquid displaced (V) = 20 cmDensity of the liquid (d) = 0.8 gmMass of liquid displaced (m) = V × d = (20 cm) × (0.8 gm)So, weight of liquid displaced (m) = 16 g.Upthrust = Weight of liquid displaced = 16 gf.Hence, new reading of the spring balance= (125 – 16) = 109 gf.

लोकतंत्र (शाब्दिक अर्थ "लोगों का शासन", संस्कृत में लोक, "जनता" तथा तंत्र, "शासन",) या प्रजातंत्र एक ऐसी शासन व्यवस्था और लोकतांत्रिक राज्य दोनों के लिये प्रयुक्त होता है। यद्यपि लोकतंत्र शब्द का प्रयोग राजनीतिक सन्दर्भ में किया जाता है, किन्तु लोकतंत्र का सिद्धान्त दूसरे समूहों और संगठनों के लिये भी संगत है। मूलतः लोकतंत्र भिन्न-भिन्न सिद्धान्तों के मिश्रण बनाती हैै।लोकतंत्र एक ऐसी शासन प्रणाली है, जिसके अंतर्गत जनता अपनी मर्जी से चुनाव में आए हुए किसी भी दल को वोट देकर अपना प्रतिनिधि चुन सकती है ,तथा उसकी सत्ता बना सकती है। लोकतंत्र दो शब्दों से मिलकर बना है ,लोक + तंत्र लोक का अर्थ है जनता तथा तंत्र का अर्थ है शासन!EXPLANATION:HOPE it's helpful for you so if you think my answer is write then please follow me and THANK my ANSWERS and mark me as BRAINLIST please please..........

ined FLOW is observed when FLUID is MOVING with SLOW velocities. Water flowing slowly in a pipe and motion of spermatozoa are examples of streamline flow. Motion of water flowing in a RIVER and motion of blood in arteries are examples of turbulent flow.

Holo MATE !!☺️that's your ANSWER.....EXPLANATION:it is TOM and JERRY

The RECTANGULAR cavity INSIDE the prism works as a rectangular prism and hence produces no deviation to the path of a light ray that passes from its parallel faces.So, the total deviation produced by a prism is REMAINED the same with or without a cavity. Hence option (A) is correct.(A) There will not be any effect of a cavity on δ (ANGLE of deviation)FURTHERMORE, if the minimum angle of deviation of any prism is δm and the angle of the prism is A, then the refractive index of the prism is given by:where, μ = √2 , ∠A = 60° (equilateral prism)The above equation does not hold good for δm = 30°. So, options (C) and (D) are not true.The only correct option is (A).

tion:Magnetism is the POWER to ATTRACT. It refers to the attraction to IRON and other metals in electric currents and magnets, or to the other kind of attraction — where people WANT to be close to each other. Different kinds of magnetism cause some magnets to attract, while others repel.

is a member of allenes. PROPADIENE, STABILIZED APPEARS as a COLORLESS flammable gas.

Speed is not a vector QUANTITY. It has only MAGNITUDE and no DIRECTION and hence it is a scalar quantity.

your answer☺☺☺☺☺...................

At time t = 0.102 sec VELOCITY of particle will BECOME half of its initial velocity.Explanation:Initial velocity of particle (at time t=0) is u = 2 m/s Particle is moving UPWARD.ACCELERATION due to gravity for motion of particle would be taken as, g = -9.8 m/s²[ Negative acceleration due to gravity because particle is moving upward]we need to FIND the time when the speed of particle will be half the initial speed.means., final velocity, v = 1 m/s Using the first equation of motion→ v = u + a t→ 1 = 2 + (-9.8) × t → 1 - 2 = -9.8  t→ -1 = -9.8  t→ t = 0.102 sec     [ Approx. ]Therefore,At time t = 0.102 seconds., the velocity of the particle will become half of the initial velocity.

tion:Ohm's law states that the voltage across a conductor is directly PROPORTIONAL to the current FLOWING through it, PROVIDED all physical conditions and temperature remain CONSTANT. In the equation, the constant of proportionality, R is Resistance and has UNITS of ohms, with symbol Ω.

A man walking on the ground: While walking, a PERSON pushes the ground in the backward DIRECTION, and the ground in return pushes the person in the forward direction, thus MAKING him/her walk. 3) A bird while flying pushes the AIR DOWNWARDS with the help of its wings.I hope this answer is help you

Mass is the amount of matter in an OBJECT. Scientists often MEASURE mass with a balance. A TYPE of balance called a triple beam balance is pictured in FIGURE below.I hope this answer is HELP you

tion:light-year is a UNIT of distance. It is the distance that light can travel in ONE year. Light moves at a velocity of about 300,000 KILOMETERS (KM) each SECOND. So in one year, it can travel about 10 trillion km.1 light-year =9.461 × 1015 metres

the CORRECT ANSWER is 7S

16Explanation:v^2 = u^2 + 2asv = 10v^2 = 10*10 = 100u^2 = ?a = 5s = 8.4so,v^2 = u^2 + 2as100 = u^2 + 2*5*8.4100 = u^2 + 10*8.4100 = u^2 + 84100 - 84 = u^216 = u^2u = 4

is the force which moves an aircraft through the AIR. ... Since THRUST is a force, it is a vector quantity having both a magnitude and a direction. The ENGINE does work on the gas and ACCELERATES the gas to the rear of the engine; the thrust is generated in the opposite direction from the accelerated gas.
