Image formation in a plane mirror |
|
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. |

07 How can you determine magnitude of displacement- , covered by an object from its velocity timegraph. |
|
Answer» You can use a velocity VS. time graph to calculate the displacement of an object in straight-line MOTION. The AREA between the graph line and the time axis equals the object's displacement over that time PERIOD. |
|
| 18. |
a person runs along a circular path of radius 5m find the magnitude displacement if he runs all the way around the circle |
|
Answer» The displacement will be zero, because displacement= FINAL POSITION - Initial position and in the case of CIRCLE its final position and initial position became same after some TIME. |

For a concave mirror f=5cm,u=10cm,v=10cm,as per sign convention rules is correct |
|
Answer» Since, object is always placed in FRONT of the mirror hence the sign of object is taken as negative. Since, the centre of CURVATURE and FOCUS LIE in front of the concave mirror, so signs of radius of curvature and focal length are taken as negative in the case of concave mirrorExplanation:Hope HELPS you |

Consider two conducing plates A and B, between which the potential difference is 5V, plate A being at a higher potential. A proton and an electron are released at plates A and B respectively. The two particles thenmove towards the opposite plates - the proton to plate B and the electron to plate A. Which one will havea larger velocity when they reach their respective destination plates?A) Both will have the same velocity B) The electron will have the larger velocityC) The proton will have the larger velocity D) None will be able to reach the destination point |
| Answer» ANSWER is B.THE ELECTRON WILL HAVE LARGER VELOCITY.Between two conducting plate,there is the uniform electric field and therefore the same charge is applicable on both PROTON and electron.Since proton mass is more than that of electron it will have less acceleration and hence less speed ACHIEVED by it. So electron will reach the plate with LARGE velocity.please MARK as brainliest | |
