eart BEAT RATE =  1.2 times per secondVolume of blood pumped =   1.0 x 10-4 m3 of blood per beat.PRESSURE = 14Kpa .To Find:The power output of the HEART.Solution:Power output of the heart is given by pressure x volume of blood x heart rate.Therefore,Power = pressure x volume x heart beat P = 14 x 10³ x x 1.2P =  1 . 68 WattTherefore,The power output of the heart is 1.68 W.

V be the potential DIFFERENCE measured across ReistanceLet I be the current flowing across the RESISTANCE.t= time for which the current flows.By the Definition of current,I=Q/tTotal charge q,  flowing through resistance will be: Q=IxtWorkdone in carrying the charge will be :W=Vxq=VxIt=I²Rt ii) The one having LESS resistance will have more power as P=V²/R Thus Power and Resistance are INVERSELY proportional....Plz mark BRAINLIEST....^_^

0.05 SV =∆ttherefore V= 8× 0.05 =0.4 m/s

the following :Gravitational force is directly proportional to the PRODUCT of the MASS of objects .Gravitational force is inversely proportional to the DISTANCE between the objects.On doubling both the masses , the gravitational force will INCREASE by 4 th of the original because each masses are now doubled and they are multiplied.On doubling the distance the gravitational force will DECREASE by one - fourth because it is inversely proportional to the square of the distances.Now the gravitational energy will become = 4 × 1/4 th Hence the gravitational force will be the same .

VCeff= 10×20/20+10       =20/3μFSince, the capacitors are CONNECTED in series, charge will be same on both C1 AND C2Qeff= ceff×V       =20/3× 10⁻⁶×3×10³       =20×10⁻³       ==> 20000μC.39)The given CIRCUIT is in PARALLEL connection. So, potential through all the CAPACITOR s will be same the charge varies.So,Q₂=C₂ₓV     =6ₓ10⁻⁶ₓ90     =540μC

rmometer is the ODD one.All the other BELONGS to the ELECTRIC circuit.The voltmeter is used to measure the potential difference.The galvanometer is used to measure the CURRENT.An ammeter is used to measure current in amperes.The thermometer is used to measure temperatureSo thermometer is the odd one.Hope this helps you.

ges are OBSERVED in focus length of mirrorit's because the focul length depends on the STRUCTURE of MIRROR which REMAINS unchangedwhile focus length of convex lens will INCREASE

lenses are thicker at the middle. Rays of light that pass through the lens are brought closer together (they converge). A convex lens is a converging lens.When parallel rays of light pass through a convex lens, the REFRACTED rays converge at the focal point. The image FORMED is magnified (you can use this lens as a MAGNIFIER, or a SIMPLE camera lens by itself). It’s also called “positive” lens.Concave lenses are THINNER at the middle. Rays of light that pass through the lens are spread out (they diverge). A concave lens is a diverging lens.When parallel rays of light pass through a concave lens the refracted rays diverge so that they appear to come from one point called the principal focus. The image formed is diminished. It’s also called “negative” lens. This lens can’t be used to form an image by itself, but in combination(s) with positive (converging) lenses it is used to shorten the focal length.This is just a basic, simple answer to your question. There are many types or shapes of concave / convex lenses (including their combinations) and I could easily go on for a week about optics I hope this answer is helpful to u...❤❤❤Keep Asking... ✌️✌️✌️✨✨✨If help u.

quantity is one which has MAGNITUDE but no direction. A vectorquantity is one which has bothmagnitude and direction. Thedirection of current is OPPOSITE to the FLOW of electrons. ELECTRIC current hasboth magnitude and direction so ideally it 'should' be a VECTOR.

ow is a natural SPECTRUM of sunlight in the form of BOWS appearing in the sky when the sun shines on rain drops.It is COMBINED result of REFLECTION, refraction and dispersion of sunlight from water droplets, in atmosphere.Always it formed in the direction opposite to the sun.

is so far away that it practically shines EQUALLY at the equator and the POLES. But why is the equator very hot and the poles very cold?There are several factors that influence the amount of sunshine received at various places on the earth.The major factor is that while the sun is overhead at the equator, it is at a rather slant angle at the poles. This effect can be demonstrated using a torch, which can be taken as the sun. What really COUNTS is the amount of sunshine that falls on a given area. At the equator, the area A receives the same amount of sunshine as another area B at a higher latitude. Since, from Figure 1, B is clearly greater than A, the amount of sunshine that falls on a unit area (for instance a square metre) at area B is less than that at area A. In other words, for the same area of 1 square metre, the amount of sunshine received is greater at A than at B.Figure 1: With the beam at an angle, area B is greater than area A.Figure 2: Rays from the sun to the earth. The area lit by the sun's ray is greater at A than at B. So, the solar energy falling on a unit area is greater at the tropics than at higher latitudes.The other factors, which are less important, include:-a) Absorption and scattering of sunshine when passing through the atmosphere - the amount of absorption and scattering depends on the nature and concentration of AIR molecules and small particles in the atmosphere. All things being equal, at higher latitudes the sun's path is longer. Naturally, there are more air molecules and particles along the way, resulting in greater absorption and scattering. Hence less solar energy reaches these places.b) Reflection by the earth's surface. As the sun's ray reaches the earth, some of the energy is reflected back and does not WARM up the place. The amount of reflection depends on the nature of the surface. Snow is an extreme in terms of reflection, since as much as 75 to 95% of the incoming sunshine is bounced back - not much help for the already cold weather in snow-covered areas. However, with an overall decreasing trend in snow cover in recent years due to climate change, more and more solar energy gets absorbed. A very likely consequence is still warmer conditions and less snow cover, further aggravating the equilibrium.

lum could not exist at the center of the Earth. Hypothetically, if it could exist, it WOULD REMAIN stationary. A pendulum REQUIRES gravity in order to work. There is no net gravity at the center of the earth because any object that existed there would FEEL equal attraction from the mass of the earth in every direction AROUND it.

fects of Compact Urban Form” is prepared for the Coalition for Urban Transitions – a major initiative supporting decision makers to improve the performance of their cities, including reducing climate change risks. It stems from a need for cities to develop policy interventions that redress the negative impacts of compactness, meanwhile retaining the benefits to deliver “healthier and GREENER cities” (page 3). It is important to note, however, that a significant proportion of its literature base presents empirical EXPERIENCE from the US and Europe. And while there is LITTLE disagreement that the benefits of compact urban form outweigh the costs in developed nations, there is significant debate about compactness and density in DEVELOPING nations, where higher density intensifies health risks associated with poor or lacking infrastructure and housing (pages 5 and 16).please mark me as brainlest
