12:58 scaler quantity 18:21 vector quantity 19:25 true 24:24 0.5m/s 29:22 displacement is 5 HW 1) 15m/s -> 54 km/h 2) 36m/s -> 129.6 km/h Thank you sir for this great explanation
09:12 displacement will be 2×radius which is diameter. 13:03 speed is a scalar quantity 19:25 The statement is TRUE 24:25 To convert 1.8 km/h in m/s multiply 1.8 km/h by 1000/3600 =1.8×1000/3600 =1.8×5/18 = 0.5 m/s Homework 1) 54 km/h 2) 129.6km/h
19:30 this statement is true because if object is moving in a straight line for e.g. a to b then it distance and displacement will be same and their is speed for distance and velocity for displacement and they are same.
13:00 scalar quantity 19:25 true 24:29 0.5 H/w a) 54 km/h b) 129.6 km/h 29:15 it will form a right angle triangle so by applying pythagoras thereom (Hyp) 2 =(perp)2 +(base)2 (AC)2=(AB)2 +(BC)2 (AC)2 = (4)2 +(3)2 (AC)2 = 16 +9 (AC)2 = 25 (AC)2 = (5)2 AC = 5
29:15 displacement 5m because 4 ka square 16 and 3 ka square 9 when we add both 25 came which is square root of 5, hence proved displacement is 5 metre❤❤❤
29:27 Displacement = Diagonal of the rectangular track Diagonal of the rectangular track = according to the Pythagoras theorem hypotenuse ² = base ² + perpendicular side ² = 4²m + 3²m . Diagonal = √25 Diagonal = Displacement = 5m 🎉🎉🎉 Sir you teaches very good Sir my name is Jaideep 🎉🎉🎉

Great job 👏
Good
Acha
09:12 displacement will be 2×radius which is diameter.
13:03 speed is a scalar quantity
19:25 The statement is TRUE
24:25 To convert 1.8 km/h in m/s multiply 1.8 km/h by 1000/3600
=1.8×1000/3600
=1.8×5/18
= 0.5 m/s
Homework
1) 54 km/h
2) 129.6km/h
29:21 According to the Pythagoras theorem
Hypotenuse ²=base²+perpendicular ²
AC²=AB²+BC²
AC²=(4)²+(3)²
AC²=16+9
AC²=25
AC=√25
AC=5
So, displacement=5m
8:59
Displacement in 1 round=diameter=2*r
=2*7
Displacement =14metres
29:16
Displacement = length of diagonal = AB² + BC² = AC² ( by Pythagoras theorem)
4² + 3² = AC²
16 + 9 = AC²
25 = AC²
√25 = AC
5 = AC
5 m is displacement 😊😊

Hw 26:28 a) 54 km/h
B) 129.6
19:30 this statement is true because if object is moving in a straight line for e.g. a to b then it distance and displacement will be same and their is speed for distance and velocity for displacement and they are same.

a) 54 km/h
b) 129.6 km/h
29:15 it will form a right angle triangle so by applying pythagoras thereom
(Hyp) 2 =(perp)2 +(base)2
(AC)2=(AB)2 +(BC)2
(AC)2 = (4)2 +(3)2
(AC)2 = 16 +9
(AC)2 = 25
(AC)2 = (5)2
AC = 5
18:36 true

29:15 displacement 5m because 4 ka square 16 and 3 ka square 9 when we add both 25 came which is square root of 5, hence proved displacement is 5 metre❤❤❤
13:01 scalar quantity is the correct answer as speed includes time and distance.
29:27
Displacement = Diagonal of the rectangular track
Diagonal of the rectangular track = according to the Pythagoras theorem hypotenuse ² = base ² + perpendicular side ²
= 4²m + 3²m .
Diagonal = √25
Diagonal = Displacement = 5m
