Just what is a second, exactly? The question has been open to INTERPRETATION EVER since the first long-case grandfather CLOCKS began marking off SECONDS in the mid-17th century and introduced the concept to the world at large.The answer, simply, is that a second is 1/60th of a minute, or 1/3600th of an HOUR. But that’s just pushing the question down the road a bit. After all, what’s an

The plasma may then be INJECTED into a magnetic field or may be generated in the field where more energy is IMPARTED to a selected isotope than to the others. FINALLY, the isotopes are separated from each other on the basis of their DIFFERENTIAL energies.Explanation:please mark me as BRAINLIST

tion:In the most BASIC SENSE, dy means change in y in a FUNCTION, just as dx represents the change in x. dy/dx refers to the change in SLOPE on a function, being rise over RUN.

Group 5 (by IUPAC style) is a group of ELEMENTS in the PERIODIC table. Group 5 contains VANADIUM (V), NIOBIUM (Nb), tantalum (Ta) and dubnium (Db). This group LIES in the d-block of the periodic table. The group itself has not acquired a trivial name; it belongs to the broader grouping of the transition metals.

If you are outside, stay outside.The GREATEST danger from FALLING debris is just outside doorways and close to outer walls of buildings. GO to an open area away from TREES, telephone poles, and buildings. Once in the open, get down low and stay there until the SHAKING stops.

Volume IncreasesExplanation:Because as you hear WATER PARTICLES gain more ENERGY and they move AWAY from each other. Thus increasing volume.

We need to USE the ideal gas law PV = nRT.  We have two conditions, which I'll note with the subscripts 1 and 2, for the INITIAL and final conditions. The values for each are: P1 = 15atm V1 =  110L n1 = 2kg T1 = CONSTANT P2 = 18atm V2 =  110L n2 =  X T2 = constant The values for each are: P1 =   P1V1 = n1RT1 and P2V2 = n2RT2 Note that neither the volume nor the temperature change, so V1 = V2 and T1 = T2. We can divide one equation by the other, and cancel the values that do not change: (P1V1)/(P2V2) = (n1RT1)/(n2RT2) Cancel the volumes and temperatures, since they do not change. (P1)/(P2) = (n1)/(n2) I'll invert this to get the ratio n2/n1 n2/n1 = P2/P1 n2/n1 = 18atm/15atm n2/n1 = 1.2 2kg * 1.2 = 2.4kg air needed to increase pressure to 18 atm. Note that n1 and n2 should both be in units of MOLES for the ideal gas law, but we are LOOKING at the ratio of n2 to n1 and all gases have a value of 22.4 L/mole at STP.  So the ratio of n1/n2 should also be the ratio of those gases in mass, since we aren't changing the composition ("air"). Explanation:thank you

if DIRECTION of force is reversed , the magnitude of the torque remains same while the direction GETS OPPOSITE hope that helps ✌

tion: National GEOGRAPHIC described NUCLEAR fusion as the "holy grail for the future of nuclear power." Not only would it produce more ENERGY more safely, it would also produce FAR less harmful radioactive waste than FISSION, from which weapons-grade material in spent fuel rods taking millions of years to decay༶•┈┈⛧┈♛♛┈⛧┈┈•༶

In PHYSICS, energy is the quantitative property that must be transferred to a body or PHYSICAL SYSTEM to perform WORK on the body, or to heat it. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not CREATED or destroyed.

There is substantial EVIDENCE that human activities, especially burning fossil fuels, are leading to INCREASED levels of carbon dioxide and other GREENHOUSE gases in the ATMOSPHERE, which in turn amplify the natural greenhouse effect, causing the temperature of the EARTH's atmosphere, ocean and land surface to increase .

A car moving TOWARDS north TURNS SOUTH that MEANS it stops and turns towards south So ACCELERATION = v-u/t = 0-40/10 = -4m/s²

ptics, or optical fibers, are long, thin STRANDS of carefully drawn glass about the DIAMETER of a human hair. These strands are ARRANGED in bundles called optical CABLES. We RELY on them to transmit light signals over long distances.

tion:In surveying, tape correction(s) refer(s) to correcting measurements for the effect of slope angle, expansion or contraction DUE to temperature, and the tape's sag, which varies with the APPLIED tension. Not correcting for these EFFECTS gives rise to systematic errors, i.e. effects which ACT in a predictable manner and therefore can be corrected by mathematical methods.Please MARK me as brainliest!!

Can't UNDERSTAND!!Explanation:A push or PULL which changes or tends to change shape, size and direction of any OBJECT is called FORCE.

Explanation:▶️ To find acceleration in the velocity-time GRAPH we have to USE the SLOPE of the graph. And then further we have to use the formula. If the slope is high then the acceleration is positive, if the solve is low then the acceleration is negative and if the slope is parallel to time axis then there is no acceleration taking place!▶️ To calculate the distance or displacement from a velocity-time graph we have to calculate the area under the curve! Required solution: a) AccelerationAcceleration in section OA!Here, initial velocity is 0 m/s, final velocity is 30 m/s and time taken is 8 seconds (because 8-0) b) RetardationRetardation in section AB! Here, final velocity is 0 m/s , initial velocity is 30 m/s and time taken is 8 (because 16-8) c) Distance covered in first 8 seconds d) Total distance travelled by the bodyArea of first TRIANGLE AOC! Here area = 120 m sq. Area of second triangle ACB! Here area = 120 m sq. Therefore, total distance! e) Average velocity in the region ACB.Explanation: We know that average velocity = Total displacement/Total time and here total displacement is 240 m and total time is 16 seconds.

Given, H=1000J;R= 40 OHM ;Then, I =√H/RT = √1000/40x1 =√25 =5ATherefore, P.D= IR =5x40 =200V
