Answer» Answer: Ice melting INVOLVES a change from a solid to a liquid and the substances maintain the properties of water because the molecules never change. 2. Water boiling is a physical change as water molecules VIBRATE faster, they enter the GAS phase and become water vapor. 3. Rubbing alcohol left uncovered will evaporate quickly into the air. It turns to a gas but maintains the properties of alcohol. 4. Hot molten iron is a liquid and when left to cool will from solid steel and can take many forms. 5. Dissolving sugar in water is a physical change. The solid sugar never loses its properties, the molecules become separated by water and the sugar can easily be recovered by EVAPORATING the water. Explanation: physical change is any change in matter that involves the substance going from one physical state to another. The reference to a physical state involves solids, liquids, and gases. When a substance UNDERGOES a physical change it does not lose its original properties when changing from one phase to another. The types of physical changes can vary.

5. Differentiate between static and sliding friction. |
|
Answer» Static friction is the the TYPE of friction that PREVENTS an object from moving, keeping it in static. An example of static friction is a car parked on an incline. The friction stops the car from going downhill. Sliding friction is the friction that most people ASSOCIATE the word "friction" with. It is the friction that opposes the sliding motion and tries to reduce the speed at which the surfaces SLIDE across each other. An example of sliding friction would be a ice sliding across ice and then coming to a stop. Sliding friction is also known as KINETIC friction. Hope it helps :) |

Points to RememberThe Speed of light in vacuum is 3 × It is also considered that the speed of light in air is 3 × The light rays was always travel in the straight line. Required ExperimentExperiment to show light rays always travel in straight line :- 1. Take 3 cardboard, make hole at similar height. 2. Keeping apart similar distance to one ANOTHER. made it stand at a similar height . 3. A Burning candle placed at the stand at a fixed height so that light rays pass through the three holes in the cardboard . 4. From last cardboard we can see the burning candle. 5. If any cardboard DISPLACE from its position then the burning candle does not APPEAR to the eyes . 6. So this shows that the light is always travel in a straight line. |

COVER crops: MULCH or cover crops are grown in between "growing seasons". These are called as green manure or green mulch that helps prevent "soil erosion" and nutrient leaching, increases the soil organic and LIVING content, and controls pests. MUSTARD and legumes like alfalfa and peas are mostly used as "cover crops". The rhizobium that symbiotically grows with leguminous plants helps the plants to fix non-absorbable nitrogen from the soil. c. Crop rotation: can be done in a planned order according to the crop seasons to prevent soil depletion and increase soil health. This method also helps to increase yield and decrease crop loss due to diseases. Hope u like it :D |

|
Answer» Answer: ◆ Answer - Total deviation of light ray = 140° ● Explanation - Given that 2 plane mirrors are inclined at an angle75 degree. SUPPOSE a ray of light is INCIDENT on 1st MIRROR at angle i. Hence, deviation at 1st mirror is 2i. Now this ray will INCIDE on 2nd mirror at angle75-i. So deviation at 2nd mirror is 2(75-i) = 140-2i. Hence, total deviation of light ray will be 2i + 140-02i = 140°. Thanks DEAR. Hope this helps you.. |
