What is variable acceleration? |
| Answer» If the velocity of an object changes by unequal amounts in equal intervals of time, the object is said to be in non-uniform or variable acceleration e.g., if the speed of a bus travelling along a straight road increases by unequal amounts, then the bus is moving with non-uniform acceleration.<br>Dont know | |

1. Why does air pressure in a car tyre increases during driving? |
| Answer» When we drive , the frictional force between the tires and the road increases the temperature of the air inside the tire. so the increase in temperature also increases tire pressure. | |

| 419. |
What is instantaneous acceleration |
| Answer» Acceleration at a particular instant of time is called instantaneous acceleration.<br>Instantaneous Acceleration- When an object is moving with variable acceleration, then acceleration of the object at any instant of time is called instantaneous acceleration. It may be also defined as the limiting value of average acceleration over an interval of time, which approaches to zero.Instantaneous Acceleration = dv/dt | |

A bollon is moving upwards with velocity 10m/s it realese a stone |
| Answer» QUESTION:\xa0A balloon is moving upwards with velocity of 10m/s. it releases a stone which comes down to the ground in 11s. find the height of the balloon when stone is dropped?ANSWERA ballon moving upwards with constant velocity 10m/s . if we release the stone from ballon , then, initial speed of stone = 10m/sec .now,\xa0initial speed = 10m/sec\xa0time = 11sec\xa0let H is the height of ballon when stone is dropped .use kinematics equation ,\xa0S = Ut + 1/2at²\xa0-H = 10 × 11 - 1/2 × 10 × (11)²\xa0= 110 - 5× 121\xa0= 110 - 605\xa0= -495 m\xa0- H = -495 mhence, H = 495 m\xa0so, height of ballon is 495m when stone is dropped . | |

What is parallex movement |
| Answer» Thanks Yogita<br>To measure large distances, we employ an important method called the parallax method.If we look at an object with one eye closed, its position seems to be moved a little from the original position.If you look at a pencil held in front of your eyes against a fixed reference point on a plain wall, with your left eye, closing your right eye and then with your right eye, closing your eye you observe that the position of the pencil seems to change with respect to the fixed reference point on the wall. This is called parallax.\xa0You may call the two eyes are two different viewpoints, since when used separately; they create different lines of sights.\xa0Distance between these two viewpoints or points of observation is called basis. Here, the basis is equal to the distance between two eyes.\xa0We use exactly the same method to measure the distance of a distant star. Instead of two eyes, we view the star from two different observatories on the earth at the same time.\xa0To measure very small distances such as the size of a molecule, special microscopes need to be used. We cannot employ devices like a Vernier callipers or a screw gauge to measure such lengths.All instruments such as simple microscope, optical microscope or an electron microscope have a certain limitations in measuring lengths. However, we can use a simpler method to estimate the size of a molecule.Let us take some oleic acid. Oleic acid is a soapy liquid with large molecular size of the order of 10–9 metre.We need to form a monomolecular layer of oleic acid on water surface so as to measure the thickness or diameter of a molecule of the acid.We learnt how to measure a tiny molecular distance or a massive stellar distance. | |
