How is the air temperature relate to the density and movement of an air mass |
|
Answer» warmer air mass travels over COLDER GROUND, the bottom layer of air cools and, because of its high density, is trapped NEAR the ground. ... Air masses are slowly pushed along by high-level winds. When an air mass MOVES over a NEW region, it shares its temperature and humidity with that region. |

Answer» World Zoonoses Day is held every year on July 6. The day commemorates July 6, 1885, when Louis Pasteur successfully ADMINISTERED the first vaccine against Rabies virus, a zoonotic disease. Theme day raises awareness for the risk of zoonotic diseases.Zoonoses are infectious diseases (virus, bacteria and parasites) that can be spread from animals to humans, and vice versa. Zoonoses can spread from direct contact with animals or indirectly, vector-borne or food-borne.Zoonotic diseases are very common, for EXAMPLE tick-borne encephalitis and borreliosis. But also many foodborne infectious diseases like SALMONELLA, Yersinia, EHEC, botulism or campylobacter are all also zoonoses. |

A force of 10 n acts for 20 second on a body of mass 2 kg initially at rest calculate the energy required by the body and the work done by the applied force |
|
Answer» tion:1) Work done = Force × distance1) Work done = Force × distanceDistance = ½ a t² = ½×5×20² = 1000 M1) Work done = Force × distanceDistance = ½ a t² = ½×5×20² = 1000 mTherefore, W. D = 10 × 1000 = 10000 J. 1) Work done = Force × distanceDistance = ½ a t² = ½×5×20² = 1000 mTherefore, W. D = 10 × 1000 = 10000 J. 2) Energy: Here it'll be kinetic energy.1) Work done = Force × distanceDistance = ½ a t² = ½×5×20² = 1000 mTherefore, W. D = 10 × 1000 = 10000 J. 2) Energy: Here it'll be kinetic energy.Therefore, K. E = ½ M V² = ½×2×10000 = 10000 J. hopefully you understand.... |

100 points with steps plsTwo electric bulbs rated 200 V, 80 W and 200 V, 40 W respectively are connected in series. If the voltage across the combination is 200 V, the power consumed by the 80 W bulb will be about. (a) 7W (b) 9W (c) 16 W (d) 20 W (e) 5W |
|
Answer» 100 W bulbs is smaller than across 60 W bulbGiven:The rating of the first bulb is 200 V−100 WThe rating of the SECOND bulb is 200 V−60 WThe resistance of the first bulb is:R 1 = 100200 2 ⇒400 ΩThe resistance of the second bulb is:R 2 = 60200 2 ⇒ 32000 ΩSince the two bulbs are connected in SERIES,The EQUIVALENT resistance of the circuit is:R eq =400+ 32000 ⇒ 33200 So the current drawn is I= 3200/3200 = 16033 Now, the voltage drop is given as V=IRSo, the voltage will be higher for the higher values of the resistance. So, the bulb of 100 W has less potential as compared to bulb of 60 |
