The odometer of a car reads 2400 km at the start of a trip and 2800 km at the end of the trip. If the trip took 8 h, calculate the average speed of the car in km/h and m/s. |
|
Answer» 50km/h , 13.88m/sExplanation:At the start = 2400kmat the end = 2800kmSo, TOTAL DIST. COVERED = 2800km - 2400km = 400 km = 400000mtime TAKEN = 8 h = 28800sSpeed in km/h = d/t = 400km / 8h = 50km/hSpeed in m/s = d/t = 400000m /28800s = 13.88m/s |

A body obtains a velocity of 10m/sec in 3sec from rest .find its acceleration. |
|
Answer» tion:If the body is experiencing uniform acceleration, there will be no DIFFERENCE between average and INSTANTANEOUS acceleration. We can therefore calculate the body’s acceleration as the CHANGE in velocity over TIME. In this case: Initial velocity = 0 Final velocity = 10 m/s Δv = 10 m/s t = 3 SECONDS 10 m/s / 3 s |

Difference between atomic theory and modern theory |
|
Answer» Hey mate here is your ANSWER:___________________________________→The MAJOR difference between Dalton's atomic theory and Modern Atomic Theory is the following : Dalton says atoms of a given element are identical in mass, and the modern one says atoms of a given element are identical in average mass. Dalton says atoms of a DIFFERENT element differ in size and mass, whereas the modern theory says they differ in average mass. Dalton says atoms are indivisible particles whereas the modern theory says Atoms are divisible into sub-atomic particles like protons, NEUTRONS, and electrons.____________________________________Hope it helps you. |

An object of 7cm placed 27cm infront of a concave mirror of focal length 18cm what is the image distance |
|
Answer» GivenFocal length of concave mirror (f)= -18cmConventionally concave mirror and concave lens have negative focal lengths and convex mirror and convex lens have positive focal lengths. The co-ordinate system is taken with respect to the Pole as origin. All distances are measured from the pole and distance measured in the direction of light RAYS are positive and opposite to the direction are considered as negative. Distances above the principal axis are positive and vice-versa. Following these conventionsObject distance (u)= -27cmObject height= 7cmLet IMAGE distance be v cmWe know by mirror formula that1/v + 1/u = 1/f1/v + 1/(-27) = 1/(-18)1/v = 1/(-18) + 1/271/v= (-3+2)/541/v= -1/54v= -54 cmThus, PLACING a screen at a distance of 54 cm from the concave mirror on the same SIDE as object will give us a SHARP and focused image.The magnification will bem= -v/um= -(-54)/(-27)m= -2|m|>1 => enlarged image and the negative sign implies that the image is invertedm can also be written asm= Height of image/ Height of object-2= Height of image/7Height of image= -14cmThus the image has a height of 14 cm and is inverted and present at a distance of 54 cm from the mirror. |

Speed time graph or velocity time graph |
|
Answer» tion:The Velocity Time Graph: Velocity-time graph is a plot between Velocity and Time. It shows the Motion of the object that MOVES in a STRAIGHT Line. Magnitude of Velocity at a given instant is equal to its Instantaneous SPEED. It is drawn for 1-D motion only and can take both positive and negative VALUES. |

Image formed by reflection from a plane mirror is ______ |
|
Answer» The image formed by a PLANE mirror is ALWAYS virtual (meaning that the light RAYS do not ACTUALLY come from the image), upright, and of the same shape and size as the OBJECT it is reflecting. A virtual image is a copy of an object formed at the location from which the light rays appear to come. |
