Aorta carries the oxygenated blood from the heart to the different parts of the body via the network of arteries and arterioles. The body uses oxygen for the physiological processes of the body.
The venae cavae are large veins (venous trunks) that return deoxygenated blood from the body into the heart. In humans, they are called the superior vena cava and the inferior vena cava, and both empty into the right atrium.

HCl produce H+ ions only in the presence of water. Dry HCl does not turn blue litmus to red because it does not produce H+ ions.. Hydrochloric acid is an aqueous solution so it can produce H+ ions and can turn blue litmus to red.

Noble metals such as gold and platinum do not corrode easily.

Corrosion is a natural phenomenon. Corrosion is a chemical reaction that takes place between metal and oxygen in the presence of moisture. The most active metals which tend to lose electrons easily such as magnesium and aluminum corrode easily. The most stable metals those which do not lose electrons easily such as gold and silver do not corrode easily.

Jagrati Sharma?? 5 years, 5 months ago

Sadness is also a very active, lively, emotion. This may surprise us but the goal of sadness is actually to help us feel strong, alive and courageous in the face of life's adversities. It forces us to stop and focus, and so it is common to feel more tired, slower, and less receptive to everything around us.

? Pranali.A.P ? 5 years, 5 months ago

Sadness is an emotional pain associated with, or characterized by, feelings of disadvantage, loss, despair, grief, helplessness, disappointment and sorrow. An individual experiencing sadness may become quiet or lethargic, and withdraw themselves from others.

Rocks that r formed due to the deposition and solidification of sediments ,especially sediments transported by water. They r often deposit in layers ( hope u got it)..

Prakash Pant 5 years, 5 months ago

Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding. Many of the picturesque views of the desert southwest show mesas and arches made of layered sedimentary rock. Common Sedimentary Rocks: Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock. Tuffaceous sandstones contain volcanic ash. Clastic Sedimentary Rocks: Clastic sedimentary rocks are the group of rocks most people think of when they think of sedimentary rocks. Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock. Clastic sedimentary rocks may have particles ranging in size from microscopic clay to huge boulders. Their names are b ased on their clast or grain size. The smallest grains are called clay, then silt, then sand. Grains larger than 2 millimeters are called pebbles. Shale is a rock made mostly of clay, siltstone is made up of silt-sized grains, sandstone is made of sand-sized clasts, and conglomerate is made of pebbles surrounded by a matrix of sand or mud. Biologic Sedimentary Rocks: Biologic sedimentary rocks form when large numbers of living things die. Chert is a example for this type of rock, and this is one of the ways limestone can form. Limestone can also form by precipitating out of the water

ANSWER

A wire of resistance 20 ohm is bent in the form of a circle. What is the effective resistance between two points at the end of any diameter of the circle?

Posted by Lavanya Kohli 5 years, 5 months ago

CBSE > Class 10 > Science

1 answers

Sia ? 4 years, 7 months ago

Resistance given here is 20 ohm
As it is bend into wire so, L = 2πr
so, Ri = Rho×2πr/A = 20 ohm
Now, resistance between two point at the end of diameter can be given by
1/R = (1/Ri/2)+(1/Ri/2) {as half of the wire is attached to the other half so it may be considered as parallel connection}
1/R = 1/10+1/10 { Ri = 20ohm so Ri/2 = 10 ohm }
or 1/R = 2/10
so, R = 5 ohm ,(across ends of diameter)

ANSWER

Derive the formula of equivalent resistance when two resistors are connected in: Series combination Parallel combination How will these formulas change for two equal resistors?

Posted by Vanshika Verma 5 years, 5 months ago

CBSE > Class 10 > Science

1 answers

Meghna Thapar 5 years, 5 months ago

Combination of three resistors in series

The potential difference across R3 =V3 = I R3. Thus, in case of series connection, the equivalent resistance, Req = V/I = (R1+ R2+ R3). For n number of resistors connected in series, the equivalent resistance Req = R1+ R2+ R3…………………Rn. The same current flows through each resistor in series. Individual resistors in series do not get the total source voltage, but divide it. The total resistance in a series circuit is equal to the sum of the individual resistances: RN(series)=R1+R2+R3+… In a series circuit, the sum of the voltages consumed by each individual resistance is equal to the source voltage. Components connected in parallel are connected along multiple paths so that the current can split up; the same voltage is applied to each component.
