How to calculate your height (5'3 inch) in meter and cm by scientific formula..please help me |
|
Answer» Answer: SEE down Explanation: centimeters] = [feet] * 30.48 + [INCHES] * 2.54,To CONVERT 5 ft and 3 in to cm you have to MULTIPLY the number of feet by 30.48 and add it to number of inches MULTIPLIED by 2.54. 5.3 feet equal 161.544 centimeters (5.3ft = 161.544cm). This will give you the total height in centimeters. |

Define Force ?Tysm all ♡♡~ |
|
Answer» Answer: In physics, a force is any INFLUENCE that, when unopposed, will change the motion of an object. A force can cause an object with MASS to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both MAGNITUDE and direction, MAKING it a vector |

obtain an expression for the electric field intensity at a point outside an infinitely long charged cylindrical conductor |
|
Answer» Answer: Consider an isolated infinitely long cylindrical conductor A, of radius R and carrying a charge per unit length (linear charge density) λ. Consider a point P outside the conductor at a distance r from its axis. To find the electric field intensity at P, we choose a cylindrical Gaussian surface S of radius r through P and coaxial with conductor A. A small area ELEMENT containing P has an area dS. Charge is UNIFORMLY distributed over the outer surface of the conductor. Then, by symmetry, the electric field intensity at any point outside the conductor is at right angles to the cylinder axis. Hence, the component of the electric field intensity perpendicular to the plane circular faces of the Gaussian surface is zero. Therefore, the TOTAL normal electric induction (TNEI) through these FLAT faces is zero. At every point on the curved face of surface S, by symmetry, the electric field intensity E→ is normal to S and has the same magnitude E. If the charge on conductor A is positive, E→ is directed along the outward DRAWN normal.ion: |

Which of the followings is not a characteristic of a shadow? * 1 point A. A shadow is a dark outline of the object. B. The shape of the shadow may or may not match with the shape of the object. C. The size of shadow increases if the opaque body is close to the source of light. D. Objects of different colours, but of same shape form different kind of shadows |
|
Answer» Answer: D is not a CHARACTERISTIC of a shadow bacause all the shadow FORMED are black and the factors affecting shadow are the shape and size of the object, and the DISTANCE of the object from the source of LIGHT. |

Answer» Answer: What's your doubt? 11th >Motion in a Plane >Uniform Circular Motion >State which of the followin... Physics Bookmark State which of the following situations are possible and give an example for each of these: (a) An object with a constant acceleration but with zero velocity. (b) An object moving in a certain direction with an acceleration in the perpendicular direction. Medium share Share Video Explanation Solution To Question ID 464649 play-icon Answer (a) Let say a stone is thrown in vertical direction with INITIAL speed u. As the time passes its velocity decreases and at the maximum HEIGHT it attained, its velocity is zero but it has an acceleration (9.8)m/s 2 in the downward direction due to gravity. (b) When a pebble is tied with an end of string and it is whirled in horizontal circular motion with the other end of the string at the centre of circular path, then it has a constant magnitude of CENTRIPETAL acceleration TOWARDS the centre. Hence the acceleration is in perpendicular direction to the motion of pebble. |

Answer» ok Answer❣ Question : An object TRAVELS 20m in 4s and then other 20m in 10s . What is the average speed of the object ? SOLUTION : As per the question we have TWO cases so let's assume each as CASE 1 and Case 2 respectively ! Case 1 : Distance Covered : 20m Time taken : 4 sec Speed : Distance / time : 20 / 4 : 5 m / sec Case 2 : Distance Covered : 20 m Time taken : 10 sec Speed : Distance / time : 20 / 10 : 2 m / sec huge average speed = total distance total time averagespeed=totaltimetotaldistance = \5 + 2 4 + 10=4+105+2 = 7 40 = 0.175=407=0.175 Hence , the average speed of the object is 0.175 m / sec !! |
