- How will the magnetic field intensity at the
centre of a circular coil carrying-current
change, if the current through the coil is
doubled and radius is halved?
(HOTS)​

Answer:

( - 15, - 16 )

Step-by-step explanation:

Coordinates of midpoint are ( [tex]\frac{x_{1} +x_{2} }{2}[/tex] , [tex]\frac{y_{1} +y_{2} }{2}[/tex] )

( - 5 + x ) / 2 = - 10 ⇒ x = - 15

( 4 + y ) / 2 = - 6 ⇒ y = - 16

( - 15, - 16 )

Answer:

B

Step-by-step explanation:

Answer:

m∠A+m∠B = m∠ACD.

m∠A = 56°

m∠B = 97°

Step-by-step explanation:

In this problem, we are given that m∠B is fifteen less than twice the m∠A.

Let m∠A = x°

This means that m∠B = 2x°-15°

Due the exterior angles theorem,

m∠A+m∠B = m∠ACD.

Since we are given that m∠ACD is 153°,

m∠A+m∠B=153°.

x+2x-15=153

x=56°

That means

m∠A = 56°

m∠B = 2(56) -15

m∠B = 97°

Answer:

125/1000

Step-by-step explanation:

you reduce this to lowest terms by dividing the numerator and denominator by 125 to get the equivalent fraction 1/8

Answer:

2nd one (14)

Step-by-step explanation:

525+50m=1225  take 525 from both sides

50m=700  divide 50 from both sides

m=14

Answer:

-66.9901960784

Step-by-step explanation:

yes

Answer:

-66.9901960784

Step-by-step explanation:

1/3 × 1/34 + (-67)

1/102 - 67

1 - 67 × 102/102

1 - 6834/102

- 6833/102

= -66.9901960784 or -67

Answer:

Step-by-step explanation:

Step one:

Given data

amount of money earned per hour= $6.25

amount of money made in tips= $8.5

if x represents the number of hours worked and

y represents the total amount earned

The linear function for the total is expressed as

y=mx+c

Step two:

Hence for the situation given the expression for the total is

y=6.25x+8.5

Say Kayla worked for 2 hours

that is x=2, the total she would have earned is

y=6.25(2)+8.5

y=12.5+8.5

y=21

For a 2 hour work, Kayla will make $21

Answer:

a = -40/3

Step-by-step explanation:

(7a - 4) = (4a - 44)

7a - 4 = 4a - 44

7a = 4a - 44 + 4

7a = 4a - 40

7a - 4a = - 40

3a = - 40

3a/3 = -40/3

a = -40/3 or -13.3333 repeating

Answer:

[tex]Q(a) = w[/tex]

Step-by-step explanation:

Given

w = weight

a = age

Required

Represent the weight as a function of age

When writing a function.

[tex]y = f(x)[/tex]

means that y is a function of x

Using the above to answer the given question, we have:

[tex]w = Q(a)[/tex]

Which means w is a function of a

and can be rewritten as:

[tex]Q(a) = w[/tex]

Answer: go to 10 the over 7 right im pretty sure

Step-by-step explanation:

Answer:

f(7) = - 5

Step-by-step explanation:

Locate x = 7 on the x- axis. Go vertically down to meet the graph, then read the corresponding value of y on the y- axis.

The y- value is - 5

Thus

f(7) = - 5

Answer:

f(12)=-2 because all you do is put 12 in for x so your equation is f(12)=1/4(12)-5

Answer:

a) Who jogs faster?

Your friend jogs faster because he jogs with a speed of 10.91 km/hr

Step-by-step explanation:

Speed = Distance(km)/Time(hours)

Question 2 How much sooner will the faster jogger finish a five-kilometer race?

Your friend's will finish a 5km race at a speed of 18.18 km/hr

Your speed is :

You jog 2 kilometers in 12 minutes.

Convert 12 minutes to hours

60 minutes = 1 hour

12 minutes = x

x = 12/60

x = 1/5 hour

Your speed is calculated as:

2km/1/5hour

= 2 km ÷ 1/5 hour

= 2 × 5

= 10 km/hr

Your friend's speed is calculated as:

Your friend jogs 3 kilometers in 16.5 minutes.

Convert 16.5 minutes to hours

60 minutes = 1 hour

16.5 minutes = x

x = 16.5/60

x = 0.275 hour

Your speed is calculated as:

3km/0.275 hour

= 10.909090909 km/hr

Approximately = 10.91km/hr

a) Who jogs faster?

Your friend jogs faster because he jogs with a speed of 10.91 km/hr

Question 2 How much sooner will the faster jogger finish a five-kilometer race?

Your friend jogs faster, hence:

3 km = 10.91 km/hr

5km = x

x = 5 × 10.91/3

x = 18.183333333 km/hr

Your friend's will finish a 5km race at a speed of 18.18 km/hr
