How can you determine the volume of solid describe the steps with |
|
Answer» Answer: To measure the volume of a piece of stone: 1.Take a piece of BRASS, a measuring cylinder, fine thread of sufficient length and some water. 2.Place a measuring cylinder on a flat horizontal surface and FILL it partially with water. 3. Note the reading of the water LEVEL very CAREFULLY. 4.Now tie the piece of brass with a thread and dip it completely into water. We see that the level of water RISES. 5.Note the reading of the new water level. 6.The difference in the initial and final water level reading's gives us the volume of stone. |

What is theory of realitivity |
|
Answer» Answer: ESSENTIALLY, it's a theory of gravity. The basic IDEA is that instead of being an invisible FORCE that attracts objects to ONE another, gravity is a curving or warping of space. The more massive an object, the more it warps the space around it Explanation: The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. Special relativity applies to all physical phenomena in the ABSENCE of gravity hope It's help you |

What are the depending factors of speed? What are the not depending factors of speed? |
|
Answer» Answer:Two factors that determine RUNNING speed are stride cadence and stride LENGTH. Stride cadence refers to the number of STRIDES taken per second, and stride length refers to the distance traveled by each stride. The product of these factors gives a mathematically ACCURATE description of running speed. |

For the following vector field F, decide whether it is conservative or not by computing the appropriate first order partial derivatives. Type in a potential function f (that is, ▽ f = F) with f(0, 0) = 0. F (x, y) = (-14x - 2y)i + (-2x + 14y)j• Answer it correctly.• Please don't spam. • Need full explanation. • Don't give any irrelevant answer.━━━━━━━━━━━━━━━━━━━━━━━━━━ |
Answer» GivenA vector field F (x, y) = (-14x - 2y)i + (-2x + 14y)j . To FindWhether this field is conservative or not. ConceptA field is CALLED conservative if it is path independent. The curl of such field will be zero. That is ▽ X F = 0. In other words, it can be SAID that a field will be conservative if it can be written as gradiant of a scalar field. In my SOLUTION, i have used this approach. I TRIED to find a scalar field whose gradiant is the given field. |
