A motorist drives south at 24.0 m/s for 3.00 min, then turns west and travels at 25.0 m/s for 2.20 min, and finally travels nort

grigory [225]

Answer:

magnitude m = 5440.26 M

average speed is = 25.05 m/s

average velocity = 14.62 m/s

Explanation:

given data

speed v1 = 24 m/s

time t1 = 3 min = 180 s

speed v2 = 25 m/s

time t2 = 2.2 min = 132 s

speed v3 = 30 m/s

time t3 = 1 min = 60 s

total time = 6.2 min = 372 s

to find out

displacement in m and average speed and average velocity

solution

so we find here displacement

displacement = vt .............1

displacement 1 = 24 × 180 = 4220 m south = -4220 j ..........2

displacement 2 = 25 × 132 = 3300 m west = -3300 i ...........3

distance 3 = 30 × 60 = 1800 m

displacement = 1800 cos45 -i + 1800 cos45 j

displacement = -1272.79 i + 1272.79 j .............4

so total displacement D = equation 2 + equation 3 + equation 4

total displacement D = -4220 j -3300 i -1272.79 i + 1272.79 j

total displacement D = -2947.21 j - 4572.79 i

so magnitude m = √(-2947.21)² + (-4572.79)² )

so magnitude m = 5440.26 M

and

average speed is = total distance / time

average speed is = (4220 + 3300+ 1800 ) / 372

average speed is = 25.05 m/s

and

average velocity = total displacement / time

average velocity = 5440.26 / 372

average velocity = 14.62 m/s

Hunter-Best [27]

The ratio of the deflection when each is connected in turns to a cell of e.m.f 25 V and internal resistance 50 ohms is 13: 12

<h3></h3><h3>What is internal resistance?</h3>

Internal resistance can be described as the resistance within a battery, or other voltage source, that causes a drop in the source voltage when there is a current.

The parameters given are :

Coil 1 = 50 turns

Coil 2 = 500 turns

Resistance 1 = 1022

Resistance 2 = 6002

Internal resistance = 50 ohms

Emf = 25v

I = 25/ 50+ 10

I = 25/60

I = 5/ 12 A

$I_{2}$ = 25/50+ 600

= 25/ 650

= 5/ 130 A

The ratio of the deflection when each is connected in turns to a cell of e.m. 25 V and internal resistance 50 ohms =

Q1/ Q2

Q1 = N1 x B x $I_{1}$ / c

Q2 = N2 x B x $I_{2}$ / c

therefore Q/ Q2 = (50 x 5/12 )/ (500 x 5/130)

Q1 / Q2 = 12/ 13 which 13: 12

Therefore, The ratio of the deflection when each is connected in turns to a cell of e.m. 25 V and internal resistance 50 ohms is 13: 12.
