Q1 Ans ) A speedometer of a vehicle measures the speed. Q2 Ans ) No , because a particle moving with uniform speed may or may not have uniform velocity. Q3 Ans ) Speed of the car at the first half = 20 km/h Speed of the car at the second half = 30 km/h Speed = Distance/time = 50/2 = 25 km/h ∴ The average speed of the car is 25 km/h
@@ayaandogra1456 first you have to take distance=X,( A to B = X=20,B to C=X=30) distance=2X, after you have to solve time, T1= distance/ speed(T1=X/20),T2 = distance/speed (T2=X/30), {total time = X/20+X/30=5X/60},(Average speed= total distance/ total time=2X/5X/60, {X/X}=0, 2×60/5= 24Km/h.
Q1 and Q2 are correct :) Answer of Q3 is 24 km/hr. Here is solution: Let's start with the formula for average speed = total distance / total time But since the distance is not given in the sum, we can take total distance as 2x. So 1st half distance is 'x' and 2nd half also is 'x'. Now to calculate total time … Total time = time of 1st half + time of 2nd half time = distance / speed So we get total time = x/20 + x/30. Now plug in the values in the main formula Average speed = 2x / (x/20 + x/30) = 2x/ (5x/60) = 24 km/hr
1)The speedometer measures the instantaneous speed of the car. 2)The velocity of car will change if it takes turn as direction will change. 3) Let the distance be x km . So, time for first half distance= distance/speed ( X/2 )/20 hr=x /40 hr Time for second half distance = distance /speed=(x/2 )/30 hr =x /60hr Total time =x /40 hr + x/60 hr=5x/120 =x/24 hr Total distance =x km So average speed = total distance/total time = x/(x/24)km/hr =24 km/hr
TOP 3 QUESTIONS BY AVIGHNA DARUKA 1)The speedometer measures km/hour or instantaneous speed. 2)No, the car doesn't has uniform velocity since the direction has changed. 3) Easy, you find the average speed by applying the simple formula of a sum divided by count.

Q1) Speedometer measures the Instantaneous Speed. Q2) No the car does not posses uniform velocity as it has changed its path from straight line. Q3) 20+30/2 = 50/2 = 25 km/h
1.instantenous speed 2.as velocity is speed with direction, although it has a uniform speed but as it turns so it's direction is changing so velocity is not uniform 3.total distance=20km+30km=50km Total time=1h+1h=2h Avg.speed=total distance ÷total time So, =50/2km/h=25km/h

1. A speedometer measures the instantaneous speed of the vehicle. 2.As velocity includes speed and direction , when the car takes a turn the direction does not remain the same so the car does not have uniform velocity. 3. Average speed of car is 25 km/ hr.
1. The speedometer of a vehicle measures the instantaneous speed. 2. No, because the uniform motion is when the speed is constant and direction is the same. As shown in the video, the car take turn which does not meet the criteria to be included in a uniform motion; therefore, it is a Non Uniform motion. 3. The average speed of the car is 24km/h
1. The speedometer is designed to measure the instantaneous speed of the vehicles. 2. No, the car will not have a uniform motion of we will take a turn as uniform motion is the constant velocity and velocity is a vector quantity i.e it requires both magnitude and direction. So if we will take a turn then this will be a case of non uniform motion due to change in direction. 3. The average velocity of the car is 24km/h.
@@shalinisingh4356 Actually there are 2 types of methods to find out the average velocity.... The first one which I have used is called HARMONIC MEANS... This is not often used but is more accurate one...

Second method by which u have calculated is called ARITHMETICAL MEANS...This is used when the time taken between 2 successive positions is same....

Top 3 questions answers- 1) Speedometer of a vehicle measures the speed of the vehicle. 2) No it does not have uniform velocity because uniform velocity is uniform speed with direction but the direction is changing here. 3) Let the total distance be x km. Therefore, Time (a) = D/S = 1/2 x/ 20 hr. Time (b) = D/S = 1/2 x/ 30 hr. Therefore= total time = 1/2x/ 20 hr+ 1/2 x/30 hr = x/ 24 hr. Therefore average speed= total D/ total S. Therefore, x/x/24 km/hr. Therefore the answer is 24 km/hr. Sir would you please check my answers?

Q1 and Q2 are correct :)
Answer of Q3 is 24 km/hr. Here is solution:
Let's start with the formula for average speed = total distance / total time
But since the distance is not given in the sum, we can take total distance as 2x.
So 1st half distance is 'x' and 2nd half also is 'x'.
Now to calculate total time …
Total time = time of 1st half + time of 2nd half
time = distance / speed
So we get total time = x/20 + x/30.
Now plug in the values in the main formula
Average speed = 2x / (x/20 + x/30)
= 2x/ (5x/60)
= 24 km/hr

@@bhavyanayak4342 always wrong
1)The speedometer measures the instantaneous speed of the car.
2)The velocity of car will change if it takes turn as direction will change.
3) Let the distance be x km .
So, time for first half distance= distance/speed
( X/2 )/20 hr=x /40 hr
Time for second half distance = distance /speed=(x/2 )/30 hr =x /60hr
Total time =x /40 hr + x/60 hr=5x/120 =x/24 hr
Total distance =x km
So average speed = total distance/total time = x/(x/24)km/hr =24 km/hr

Q1) Speedometer measures the Instantaneous Speed.
Q2) No the car does not posses uniform velocity as it has changed its path from straight line.
Q3) 20+30/2 = 50/2 = 25 km/h
Does it means that it takes 2hrs for the car to cover the total distance
1.instantenous speed
2.as velocity is speed with direction, although it has a uniform speed but as it turns so it's direction is changing so velocity is not uniform
3.total distance=20km+30km=50km
Total time=1h+1h=2h
Avg.speed=total distance ÷total time
So, =50/2km/h=25km/h

3rd question .
car speed for half distance = 20 km /h
other half distance = 30 km/h
= 20 km/h + 30 km/h
=50 kg/h
avg speed = total distance /total time
avg speed = 50kg /h
0
because the time is not given (measure)
so answer is 50 kg /h
It's km/h
24km/hr
You can find the time as
(Total distance 's'=2x)
t1=s/v
=x/20h
And,t2=x/30h
So, total time taken=x/20+x/30
=x/12
Average speed=total distance/total time taken
=2x÷x/12
=24km/h

2) No it does not have uniform velocity because uniform velocity is uniform speed with direction but the direction is changing here.
3) Let the total distance be x km.
Therefore, Time (a) = D/S = 1/2 x/ 20 hr.
Time (b) = D/S = 1/2 x/ 30 hr.
Therefore= total time = 1/2x/ 20 hr+ 1/2 x/30 hr = x/ 24 hr.
Therefore average speed= total D/ total S.
Therefore, x/x/24 km/hr.
Therefore the answer is 24 km/hr.
Sir would you please check my answers?
Bro 3rd ques. Is wrong .
Correct. Avg speed is 24km/hr.
@@Mr.Anode_official
Please, then Give right answer of 3rd question
@@firdouswani12345 idk if u r seriously asking or if it's a sarcasm but she's right, the average speed will be 24 km/hr only
@@Mr.Anode_official it's right bro, please search in Google
yes take the bio classes for clearing our concepts
Thank you sir.
I like your explanation and your teaching skills.
You are most welcome
1) the speedometer measures the instatanous speed of the car
2) the car doesn't comes with uniform velocity. Because there is a change in direction
3) 25 km/h*2
Is these answers are correct
Sir now this consept is properly clear for me, thanks sir 👍😄
Great 👍
@@ManochaAcademy you should brush twice a day
where is your answer man
Sir what about graphs please upload video on displacement time graph please sirf its my humble request plzzz sir
It's not related to your questions but the question I will ask is similar to the topic.
A wind gust accelerates a windsurfers uniformly from a speed of 4.0m s-1 to a speed of 10m s-1 period of 50 seconds.
Q: How far does the windsurfer move in 50 seconds?
6 meters
3rd Answer is 37.5 kmph
Let total distance=2x
Time for ist half= x/20
Time for 2nd half= x/30
Now average speed= total distance/ total time= 2x divide by x/20+x/30
=37.5kmph
wrong 25
Amazing interesting ausum lecture
Thanks for liking
Q2. No because the car changes its direction as turn. While turning the car accelerates.
Correct.
No1:it is measuring the instant speed. 2:No. 3:60km/hr
Q1) speedometer measures the instantaneous velocity.
Q2)non uniform velocity.
Q3)average speed is 25km/h
Thanks sir
1. The speedometer measures instantaneous speed.
2. No
3. 25 km/hr
Your way of teaching style make different from other ❤️ love from Bihar 🙏🎉
Q.3 . Total dustance = 20 km + 30km = 50 km ,time /= 1 hr
Average speed = distance /time = 50 m/s / 60h = 1
Sir, could you please tell the answer to the 3 question along with the explanation?
Just check out the comment section.
Ok 🙏
1= km/hr
2=uniform
3= 50 km/hr
1. speedometer soch speed of a car
2. no it's a uniform speed but after changing the direction it's not a uniform velocity
3. Answer 24 km
Explaination- let distance-x
Then time teken in by 30km / hrs speed =x/30 and x/20 total time taken = x/30+x/20= 5x/60=x/12
Total distance =x+x=2x
Average speed =2x/(x/12)=(2x)×(12/x)=24
Hope it will help❤️
Thank you!
How will X/30+X/20=5x/60=X/12 plz say
U are great.. Thanks for solving all my doubt.
It's my pleasure
tq very much sir very usefull😁
Thanks for liking
ans 1 instantaneous speed
Ans2 it is not uniform velocity because the direction is changing
ans3 24 km/hr
Excellent!! All your answers are correct :) Also try the Quiz for this video on my Website. Quiz button is below the video: www.manochaacademy.com/physics/motion/l/distance-displacement-speed-velocity-2
how answer 3rd is 24 km/hr. Please tell me.
How is ans is 24 km /H???
1.) SPEEDOMETER CALCULATES THE SPEED OF THE VEHICLE AT A PARTICULAUR INSTANT
2.) NO
3.) 25km/h
