An object of size 7cm is placed at 27cm in front of a concave mirror of focal length 18cm. At what distance from the mirror should a screen be placed so that a sharp focused image can be obtained? Find the size and nature of image. |
Answer» Given:-
To Calculate:-
Solution:-By using mirror formula → 1/v + 1/u = 1/fSubstitute the value we get → 1/v + 1/(-27) = 1/(-18) → 1/v = 1/(-18) - 1/(-27) → 1/v = -1/18 + 1/27 → 1/v = -3+2 /54 → 1/v = -1/54 → v = -54 cm ∴The image distance is -54cm. Now → MAGNIFICATION ,m = hi/ho = -v/uSubstitute the value we get → hi/7 = - (-54)/(-27) → hi/7 = -54/27 → hi = -7×2 → hi = -14cm ∴ The height of the image is -14 cm. The image formed is real and inverted . |

How can we calculate the size of the image as per the magnification value of the image |
|
Answer» ong>Answer: According to new Cartesian SIGN convention, size of height of REAL and inverted image is considered negative and that of virtual and erect image is considered positive. The heigh of the object, being erect is considered positive always. So, for positive magnification, the RATIO, mentioned above, will be positive. This implies that the image height will ALSO be positive. The image will be virtual and erect. Explanation: follow me |

You leave your house on your bicycle to go visit a friend. At your normal speed of 9 mph, you know it takes you 6 minutes to get there. This time, though, when you have traveled half the distance you realize you forgot a book at home that you were going to return to your friend, so you turn around and pedal at twice your normal speed, get back home, grab the book, and start off again for your friend’s house at 18 mph (imagine you are really fit to pull this off!) (a) How far away from you does your friend live?(b) What is the total distance you travel on this trip?(c) How long did the whole trip take?(d) Draw a position versus time Neglect the time it takes you to stop and turn around, and also the time it takes you to run into your house and grab the book (in other words, assume those changes in your direction of motion happen instantly). |

A car moving over a straight path, covers a distance d with constant a speed of 40km/h and then the same distance with speed 60km/h , the average speed of car is |
|
Answer» ong>Answer: Given : ▪ A car covers first half of total distance with SPEED 40kmph and second half of total distance with speed 60kmph. To Find : ▪ AVERAGE speed of the car. Concept : ✏ If body covers first half of total distance with speed v1 and second half of total distance with speed v2, then average speed of the body is given by ☞ (v)av = 2v1v2/v1+v2 ✏ Average speed is DEFINED as the ratio of total distance travelled to the total TIME taken. ✏ It is a scalar quantity. Calculation : → (v)av = 2v1v2/v1+v2 → (v)av = 2(40)(60)/(40+60) → (v)av = 4800/100 → (v)av = 48kmph Explanation: Mark me as brainlist... |

Please don't answer if you don't know...or be reported |
|
Answer» ong>Answer: mark as brainliest Explanation: 1st-The magnetic field EXERTS a FORCE on a current-carrying wire in a direction given by the right hand rule 1 (the same direction as that on the individual moving CHARGES). ... The force on an individual charge moving at the drift velocity vd is given by F = qvdB sin θ. 2nd - Since the positively charged particle is projected TOWARDS west, so the direction of current is towards west. Now the deflection is towards north, so the force is towards north. |
