How evaporation of liquid can be increased |
| Answer» Temperature: The rate of evaporation increases on increasing the temperature of the liquid.Surface area of the liquid: The rate of evaporation increases on increasing the surface area of the liquid.Humidity of Air: When the humidity of air is slow, then the rate of evaporation is high, and water evaporates more readily.Wind Speed: The rate of evaporation of a liquid increases with increasing wind speed. | |

Drive first equation of motion |
|
Answer» Wow yigita brilliant answer The final velocity (v) of a moving object with uniform acceleration (a) after time, t.Let, the initial velocity = u.Final velocity = v.Time = tAcceleration = aWe know that, Acceleration (a) =Change in velocity/Time taken\xa0⇒ a = (Final velocity-Initial velocity)/Time taken⇒ a = (v−u)/ t⇒ at = v − u⇒ at – v = −u⇒ − v = −u −at⇒ v = u + at ---(i)This equation is known as first equation of motion. v=u+at |

In what two ways osmosis is different from diffusion |
|
Answer» Osmosis and Diffusion Differences:\t\xa0Diffusion can occur in any mixture, including one which includes a semipermeable membrane, while osmosis always occurs across a semipermeable membrane.\t\xa0When people discuss osmosis in biology, it always refers to the movement of water. In chemistry, it\'s possible for other solvents to be involved. In biology, this is a difference between the two processes. Water molecules |

Define uniform circular motion |
| Answer» When a body moves in a circular path with uniform speed or constant speed, its motion is known as Uniform Circular motion. It is possible for a body to move in a circular path with uniform speed as long as it is travelling equal distances in equal intervals of time. But the velocity of the body moving in a circle with uniform speed is not uniform because the direction of motion is constantly changing. | |

What happens to boiling point of a liquid when atmospheric pressure decreases ? |
|
Answer» As elevation increases, atmospheric pressure decreases because air is less dense at higher altitudes. Because the atmospheric pressure is lower, the vapour pressure of the liquid needs to be lower to reach boiling point. Therefore, less heat is required to make the vapour pressure equal to the atmospheric pressure. Decreases Ya |

Under what condition distance and magnitude of displacement equal? |
|
Answer» Distance and magnitude of displacement are equal in an object only if it is travelling in a straight line. Distance covered is only ever equal to the magnitude of displacement if the direction component of the object\'s velocity is constant. That is, as long as the object travels in a straight line, without doubling back, will distance = displacement ir when the body is at rest |

when a bucket filled with water is rotated over head water doesn\'t spill out explain |
| Answer» When a bucket full of water is just lifted up and inverted, the water in the bucket is strongly pulled by gravity of the earth’s surface where as there is no normal force below as there is no surface to limit fall of the water and hence it fallsWhen you rotate the water in the vertical circle, you are pushing the water away from your hand, towards the base of bucket by a force which is directed away from your hand.This force, when balances the force of gravity, the water would just be in the bucket. But when you whirl the bucket, this outward force named as Centrifugal force overcomes pull of gravity and pushes the water to the end of bucket away from the open mouth of bucket. Such that it do not drop from the open end of bucket | |

What is distance and displacement |
| Answer» Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object\'s overall change in position. | |
