Explain with an experiment that air around us exerts pressure. |
|
Answer» Answer: Gases EXERT pressure on surfaces with which they come in contact.The pressure that a gas exerts on a surface is the result of gas particles colliding with the surface. Since the gas particles move randomly in all directions, they exert pressure equally in all directions.If the volume of the gas is kept constant , its pressure increases with the increase in TEMPERATURE. For example, when the air is SUCK out of a BOTTLE, the air present out side it exerts pressure in all possible directions of bottle . DUE to this reason the bottle gets crushed.

if the unit of force work kilonewton, that of time millisecond and that of power kilowatt, what would be the unit of mass and length ? |
|
Answer» Hello Dear. Here is the answer--- →→→→→→→→→→→ Given--- Unit of Force = k N Unit of time = millisecond. Unit of Power = k W For the Unit of the Length, Using the Relation, Power = Force × Velocity ⇒ Unit of Power = Unit of Force × Unit of Velocity ⇒ 1 k W = 1 k N × Unit of Velocity
⇒ Unit of Velocity = 1kW/1kN = W/N = [Since, 1 W = N/ms] = 1 m/s. Now, Using the FORMULA, Speed = Distance/Time Unit of Speed = Unit of Distance/Unit of Time
1 m/s = Unit of Distance/1 millisecond
Unit of Distance = 1 m/s × 1 MILLISECONDS = 1 m/s × 10⁻³ seconds. = 1 × 10⁻³ m = 1 millimeter We know the unit of length is same as the unit of Distance, THUS the unit of length will be 1 millimeter. ↔↔↔↔↔↔↔↔↔↔↔ For the unit of Mass, Using the Formula,
a = ⇒ = = 10³ m/s² =1 km/s² ⇒ Unit of acceleration = km/s² Using the Formula, Force = Mass × Acceleration ⇒ Unit of Force = Unit of Mass × Unit of Acceleration ⇒ Unit of Mass = Unit of Force/Unit of Acceleration ⇒ ⇒ ⇒ Unit of Mass = kg. Thus, the unit of mass will be kg. →→→→→→→→→→ Hope it helps. Have a Nice day. |

Question answer on save water |
|
Answer» Answer: Water conservation includes all the policies, strategies and ACTIVITIES to sustainably manage the natural resource of fresh water, to protect the hydrosphere, and to meet the current and future human demand. Population, household size, and growth and affluence all affect how much water is used. Factors such as climate change have increased pressures on natural water resources especially in manufacturing and agricultural irrigation.[1] Many US cities have already implemented policies aimed at water conservation, with much success.[2] The goals of water conservation efforts include: Ensuring availability of water for future generations where the WITHDRAWAL of freshwater from an ecosystem does not exceed its natural replacement rate. Energy conservation as water pumping, delivery and wastewater treatment facilities consume a significant amount of energy. In some regions of the world over 15% of total electricity CONSUMPTION is devoted to water management. Habitat conservation where minimizing human water use helps to preserve freshwater HABITATS for local wildlife and migrating waterfowl, but also water quality. |

Mary while examining whether a boiled egg sinks or flots, found that it flots but vakula made it sink, how is it possible? Guess and write it |
Answer» ANSWER: It is possible.Explanation: I guess Mary dissolved salt in water which increases the density of water. Then Mary put the egg into the SOLUTION of water and salt in which the egg's WEIGHT is less than the solution's density. Vakula MADE it sink because dropped the egg into normal water in which the density of the egg is greater than the water. |
