Changing of m/s into km/h
1. 10m/s =10x18/5=36km/h
2. 40m/s= 40x18/5=144km/h
Changing of km/h into m/s
1. 180km/h= 180x5/18=50 m/s
2. 324km/h =324x5/18= 90m/s

Yes I know 😊

(A) is scalar
4m is distance because it has no any specific direction
5 m in east is displacement because it has specific direction
(By anmu ankur😊😊)

[@trxdevo351]

A is scalar and distance
B is the vector and displacement

[@bskrishankur8757]

Distance= Total covering path
It is circular path so we take distance as a circumference of the circle=2πr
Answer(A)= Given,
Radius of the circle=14m
circumference of circle=2πr
=2xπx14m
=88m
Answer(B)= 3½ of the distance
=3/2x88(distance)
= 132
1 note if question give 3 round then displacement is 0. But it is not so 😅😅

[@Globaljeemains]

Great answer 👏

[@trxdevo351]

Distance is 88 m and displacement is 28 m

Rohan travels 5 km and turn left and travels 12 km is straight path .Find the distance and displacement?
Answer(A) =Rohan travels
5 km in east+ 12 km in straight at left =17km {Distance is sum of all the path which actually travel by object}
Answer(B)= Rohan travels ,
5 km in east which acts as base then is turns left and travels 12 km which acts as a perpendicular .
Let ∆ ABC,
AB=5 km (base)
BC=12km(perpendicular)
Find AC =?(Hypothese)( Displacement= Shortest path of distance)
We know a Pythagoras theorem which gives us hypothenes
H²=P²+B²
H²=(12)²+(5)²
H²=144+25
H²=169
H=√169
H=13km = Displacement

[@Koshalgandhi]

Distance=88m and Displacement=28m😊😊

[@trxdevo351]

1= 36km/h
2= 144km/h
3= 50m/sec
4= 90 km/h

[@Pinkiandbantivlog]

Distance 88 m and Displacement 28m

[@trxdevo351]

Distance=17 and displacement is 13 by Pythagoras theorem

[@Koshalgandhi]

1=36km/h
2=144km/h
3=50m/s
4=90m/s
😊😊😊
