What is a watershed explain? A watershed is an area of land that drains all the streams and rainfall to a common outlet such as the outflow of a reservoir, mouth of a bay, or any point along a stream channel. Why do we need watersheds? Watersheds are important because the surface water features and […]

How long does a passive RFID tag last? about 20 years What is inside a passive RFID tags? In PASSIVE RFID Tags we have generally two main components. One is ANTENNA COIL and another is MICROCHIP. As you can see in the above image, there is no BATTERY or any other ACTIVE POWER here. How […]

What happens to equilibrium when a strong acid is added? If hydrochloric acid was added to the equilibrium mixture, both hydrogen ions (H +) and chloride ions (Cl -) are being added. Hydrogen ions are on the right hand side of the equilibrium, therefore the equilibrium will shift to the left hand side to compensate, […]

Why was Arctic sea ice so low in 2012? It’s clear that Arctic sea ice is declining over time, although there are ups and downs each year. And scientists say the melt has been driven by both global warming and other pollutants that humans have put into the atmosphere. What was the sea ice minimum […]

When a horse pulls a wagon the force that causes the horse to move forward is the force? As per Newton’s third law of motion, when a horse pulls a wagon, the force that causes the horse to move forward is the force the ground exerts on it. What is the effort needed to lift […]

Is flow rate a vector? 1 Velocity, speed, flow rate, and acceleration. Velocity indicates the distance and the direction of a motion, and is called a vector quantity. To define a vector quantity, both magnitude and direction are needed. What is the unit of flow rate? In S.I. units (International System of Units), volume flow […]

Why is current constant in a circuit? The electrons at the end of the circuit are of the same amount and of course of the same charge. Just as the battery speeds up an electron, the electron hits to another one and remains constant speed. Why is voltage constant in parallel? The voltage is the […]

What are the 7 hormones? Hormones produced by the pituitary gland Adrenocorticotrophic hormone (ACTH) Thyroid-stimulating hormone (TSH) Luteinising hormone (LH) Follicle-stimulating hormone (FSH) Prolactin (PRL) Growth hormone (GH) Melanocyte-stimulating hormone (MSH) What are the 3 main functions of the endocrine system? What Does the Endocrine System Do? Endocrine glands release hormones into the bloodstream. The […]

Which disease is the result of somatic mutation? Somatic mutations can give rise to cancer (9), as well as noncancerous diseases. Noncancerous somatic mutations that occur during development may affect cell proliferation, as would be the case in cancer, or they may simply alter cellular function without causing a proliferative effect. What causes somatic mutation? […]

What happens to the pattern if we try to determine which slit the electron goes through by using a laser placed directly behind the slits? What happens to the pattern if we try to determine which slit the electron goes through by using a laser placed directly behind the slits? If the rate of electrons […]
