Consider the motion of the object whose velocity-time graph is given in the diagram belowa) What is the acceleration of the object between times t=0s and t= 2s?b) What is the acceleration of the object between times t= 10s and t=12 s?c) What is the net displacement of the object between times t=0s and t=16s.

Answer»

Given : velocity-time graph of motion of the object

To find : acceleration of the object between times t=0s and t= 2s , & t= 10s and t=12 s . net displacement of the object between times t=0s and t=16s

Solution:

Time sec Velocity m/s

0 0

2 8

10 8

12 4

16 4

acceleration of the object between times t=0s and t= 2s = ( 8 - 0)/(2 - 0)

= 8/2

= 4 m/s²

acceleration of the object between times t=10s and t= 12s = ( 4 - 8)/(12 - 10)

= -4/2

= -2 m/s²

the net displacement of the object between times t=0s and t=16s.

= (1/2)(0 + 8)(2 - 0) + 8 (10 - 2) + (1/2)(8 + 4)(12 - 10) + 4(16 - 12)

= 8 + 64 + 12 + 16

= 100 m

acceleration of the object between times t=0s and t= 2s = 4 m/s²

acceleration of the object between times t=10s and t= 12s = -2 m/s²

net displacement of the object between times t=0s and t=16s. = 100 m

Answer»

ANSWER:

let each CHILD will GET rupees X for I year

so sumit gets = 25x

and KABIR gets = 20x

25x + 20x = 360000

45x = 360000

X= 360000÷45

X = 800

Kabir gets = 20×8000= 160000

4x+30=9x

30=9x-4x

30/5=x

x=6

orange marble=4x=4*6

Green and orange marble=24+30=54

60% of TOTAL marbles=54

60/100x=54

x=54*100/60

x=90

The ratio of the length to the breadth of a rectangle is 7 : 3. Calculate the dimensions of the rectangle if: 12.1 the perimeter is 10 cm.

Answer»

ANSWER:

Length is 3.5 cm and Breadth is 1.5 cm.

Step-by-step explanation:

Given :

RATIO of Length to breadth - 7 : 3

Perimeter - 10 cm

To find :

The dimensions

Solution :

Let the -

Let the - Length be 7y
Let the - Length be 7y Breadth be 3y

★ 2(Length + Breadth)

⇒ 2(7y + 3y) = 10

⇒ 14y + 6y = 10

⇒ 20y = 10

⇒ y = 10/20

⇒ y = 0.5

$\rule{300}{1.5}$

★ Length -

⇒ 7(0.5)

⇒ 3.5 cm

Length = 3.5 cm

$\rule{300}{1.5}$

★ Breadth -

⇒ 3(0.5)

⇒ 1.5 cm

Breadth = 1.5 cm

THEREFORE, the Length is 3.5 cm and Breadth is 1.5 cm.

Putting the value of x in equation (ii),

We get:

2(11-3y)/2 - 4y = -24

➠ 11 – 3y - 4y = -24

➠ -7y = -35

➠ y = 5……………………………………..(iv)

Putting the value of y in equation (III),

We get:

x = (11 - 3.5)/2

➠ -4/2

➠ -2

Hence, x = -2, y = 5

Also,

y = mx + 3

➠ 5 = -2m + 3

➠ -2m = 2

➠ m = -1

Therefore, the value of m is -1.

Answer» Given: please find the question. To find: distance=? Solution: POINT: $A(0,0) \ \ \ \ \ B(80, 0)$ Claculating Slop of AC, $\tan 60^{\circ} = \sqrt{3} = 1.732$ Claculating Slop of BC, $\tan 104^{\circ} = - 4.011$ Claculating Slop of AD, $\tan 125^{\circ} = - 1.428$ Claculating Slop of BD, $\tan 157^{\circ} = - 0.424$ When point C intersepts: $\to y= 1.732 x......(a)\\\to y= -4.011(x - 80)......(b)\\$ solve EQUARTION (a) and (b): $\to x_1 = 55.873 \\\to y_1 = 96.772$ When point D intersepts: $\to y= -1.428 x......(c)\\\to y= 0.424(x - 80)......(d)\\$ solve equartion (c) and (d): $\to x_1 = 18.315 \\ \to y_1 = -26.154$ Calculating diatance: $\bold{D= \sqrt{(y_2-y_1)^2 +(x_2-x_1)^2}}$ by putting the value the distance is "128.535" .

two radar stations A and B are 80km apart and B is due east of A.One aircraft is on a bearing 030 from A and 346 fromB. A second aircraft is on a bearing of 325 from A and 293 from B.How far apart are the two aircraft?

Answer»

Given:

please find the question.

To find:

distance=?

Solution:

POINT: $A(0,0) \ \ \ \ \ B(80, 0)$

Claculating Slop of AC, $\tan 60^{\circ} = \sqrt{3} = 1.732$

Claculating Slop of BC, $\tan 104^{\circ} = - 4.011$

Claculating Slop of AD, $\tan 125^{\circ} = - 1.428$

Claculating Slop of BD, $\tan 157^{\circ} = - 0.424$

When point C intersepts:

$\to y= 1.732 x......(a)\\\to y= -4.011(x - 80)......(b)\\$

solve EQUARTION (a) and (b):

$\to x_1 = 55.873 \\\to y_1 = 96.772$

When point D intersepts:

$\to y= -1.428 x......(c)\\\to y= 0.424(x - 80)......(d)\\$

solve equartion (c) and (d):

$\to x_1 = 18.315 \\ \to y_1 = -26.154$

Calculating diatance:

$\bold{D= \sqrt{(y_2-y_1)^2 +(x_2-x_1)^2}}$

by putting the value the distance is "128.535" .
