Why is it easier to push an empty object then to push an object full of books? |
|
Answer» Due the mass of the object This is because the object full of books has more mass which means that we have to apply an unbalanced force to break the force of the object |
|

How is balanced force different from an unbalanced force. Can balanced forces move a body at rest? |
| Answer» Forces are of two types – balanced forces and unbalanced forces. If the resultant of all the forces acting on a body is zero, then the forces are called balanced forces. Suppose a heavy box is lying on the ground. Let us push this box with our hands but it does not move. Though the box is at rest, four forces are acting on it – force of push, force of friction, force of gravity and force of reaction. The forces acting on a stationary box is an example of balanced forces. Thus balanced forces cannot produce motion in a stationary body or stop a moving body.If the resultant of all the forces acting on a body is not zero, then the forces are called unbalanced forces. Unbalanced forces can move a stationary body or can stop it. Suppose a toy car is lying on the ground and we push it with our hand, it starts moving because the opposing force of friction is very less. | |

Uniform circular motion is an accelerated motion ? Justify. |
|
Answer» Uniform circular motion is accelerated because the velocity changes due to continuous change in the direction of motion. So, even when the body moves ta a constant speed, its velocity is not constant. Thus, for a body moving in a circular path at a constant speed, its velocity changes continuously. The change in velocity gives rise to an acceleration in the moving body. Therefore circular motion is an acceleration motion even when the speed remains constant. No |

What the difference between solid and base einstein |
|
Answer» NICE Solid\tSolids have a fixed shape and fixed volume\tSolids cannot be compressed much\tFor example: Ice, coal, wood, stone, iron, etc.Bose- Einstein Condensate\tIn 1920 Indian physicist Satyendra Nath Bose had done some calculations for a fifth state of matter. Building on it calculations, Albert Einstein predicted a new state of matter- the Bose Einstein Condensate (BEC).\tThe BEC is formed by cooling a gas of extremely low density (about one –hundred- thousandth the density of normal air) to super low temperature. |

Why do some cells have more mitochondria? |
|
Answer» Some cells have more mitochondria,for ex fat cells store a lot of energy that is why they have more mitochondria.muscle cells also have a lot of mitochondria because they need a lot of energy to do work.In short,those cells which store energy or those who need more have more number of them Mitochondria is an organelle found in eukaryotic cells. It is often called the powerhouse of the cell because it is the location for the portion of cellular respiration that produces ATP molecules, which are the main source of energy for the cell. Mitochondria are the energy production center of the cell. |

|
| 7526. |
Why does the back of our hand feel cold when acetone gets evaporated?? |
|
Answer» As it take heat from our body to evaporate which makes us feel cool. Because the smell of acetone has less energy then the outer surroundings so,to equal the energy it absorbs the energy from the outer surroundings and evaporats the acetone and then our palm gets cold Acetone is highly sublimable. it converts into vapour at a fast rate. this increases the liquid molecules around it in vapour phase thus our palm feel cold. Due to decrease in tenperature |

What is the main work of ball bearing in machine |
|
Answer» They reduce friction Ball bearings are used in machines which have lot of movement in their working process. Ball bearings reduce the friction during motion, so that efficiency of the machines is increased, and they move in a smooth manner.\xa0The purpose of a\xa0ball bearing\xa0is to reduce rotational friction and support radial and axial loads. It achieves this by using at least three races to contain the\xa0balls\xa0and transmit the loads through the\xa0balls. |
