1st PUC Physics LBA model question paper unit test 1 with answers

[00:00:09]Welcome back to my another informative video.

[00:00:18]Motion in a straight line. These are the two chapters.

[00:00:25]One unit test in a conduct model vehicle.

[00:00:31]Anyhow, without wasting our time, let me start this video.

[00:00:38]Choose the correct answer from the given options.

[00:00:41]The units that are that are used for fundamental physical quantities are called dash and today. Right answer is option B, fundamental units is the right answer. Question number two, which of the following physical quantities has a same unit in CGS, FPS, MKS, and SI system of unit?

[00:01:06]Question number two, right answer is, my dear children, option C.

[00:01:12]Must be really time is the right answer.

[00:01:19]Question number three.

[00:01:21]If the distance covered by a particle is zero, then it's displacement is dash.

[00:01:27]Right answer is must be zero is right answer.

[00:01:31]Question number four. The slope of the tangent drawn to pause position time graph at any instant gives dash. Right answer is that is instant taneous velocity is the right answer.

[00:01:46]Instantaneous velocity is the right answer, option A. Question number five.

[00:01:51]Stopping distance of a vehicle moving with uniform acceleration is directly proportional to dash. Question number five, right answer is square of the initial velocity is the right answer is option D.

[00:02:08]Question number six.

[00:02:10]When a body is thrown vertically upward identifying the wrong statement among the following. What is our question?

[00:02:18]When a body is thrown vertically upward identify the wrong statement and I did.

[00:02:25]Velocity of the body at the highest point is zero. Velocity of the body continuously changes. Acceleration of the body continuously changes.

[00:02:35]Acceleration of the body at the highest point is -9.8.

[00:02:42]And I put it there. How can I answer it again? I don't know. Question number six, right answer that is option C. Acceleration of the body continuously changes is the right answer is option C. Question number seven, my dear children. In the summer criticize after they know the No, no, no. Statement one, statement two. You have to statement going on in the question.

[00:03:07]Let us see, my dear children. Either question number seven.

[00:03:11]Another question. Statement one is true but two is false and the Uh how do you know the choice going on in the daily? Both statement are true but two is not correct explanation of one and the Uh 90 percent with that they go. B is the right answer here today. I don't know the C question right and the killer will hit the day. They will do please clarify this answer with your subject teacher.

[00:03:39]With your core subject teacher physics lecture today. Question number seven and I will solve the discuss my record.

[00:03:46]Fill in the blanks by choosing the appropriate answers given in the bracket and I did.

[00:03:50]Dash is a supplementary quantity and right answer is plane angle is the right answer. Speed is a dash quantity and everyone knows that it's a scalar quantity. So that Question number 10, a body moving under Earth's gravitational field, the acceleration is always dash and downwards is the right answer is downwards. Next to my dear children, part B but that is not allowed answer any two of the following questions. Each question carries two marks and write any two application of dimensional analysis and out of three you are going to write any two questions and each question carries two marks. Write any two difference between really instantaneous speed and instantaneous velocity and one is there. I think three questions are there. Part C, each question carries three marks here. Write the number of significant figures in and tell me more questions put in there. You can do more and more it's a very easy man. I think derive the expressions and you can do more and more. Mention any three application of velocity time graph and you are going to attend any two question in exams. Part D, each question carries five mark. I think paper is very easy and do hard work. These questions are very very important for your annual exam. These questions are very important for your midterm exam also.

[00:05:19]God bless you all. All the best in your college unit test one more and part of the main compulsory for every college.

[00:05:28]They need to conduct must and should They should conduct unit test. Clear all of you. God bless you all. All the best my dear children.
