Answer:

A smooth, possibly curved line that you judge to come closest to all the points i.e, best fit line.

Explanation:

Line of best fit is a line through a plot of data points that best expresses the relationship between those points. The statement <em>'A smooth, possibly curved line that you judge to come closest to all the points'</em> defines the best fit line.

The other options are incorrect because we do not represent the plot of data points by horizontal or vertical lines representing their average/ midpoint values.

A circuit with a 60 V battery, a 7 Ω resistor, a resistor with 0.2 A across it, and another 7 Ω resistor in series. What is the

skelet666 [1.2K]

Answer:

28.6 ohm

Explanation:

there is a 3rd resistor in series. voltage drop across the resistors will be equal to 60v

7*.2+7*.2 +.2x = 60

2.8+.2x = 60

.2x = 57.2

x = 28.6

How much work (MJ) must a car produce to drive 125 miles if an average force of 306 N must be maintained to overcome friction?

baherus [9]

Answer:

The right solution is "61.557 MJ". A further explanation is given below.

Explanation:

The given values are:

Force,

F = 306 N

Drive,

D = 125 miles,

i.e.,

= 201168

meters

As we know,

The work done will be:

= $F\times S$

On substituting the given values, we get

= $306\times 201168$

= $61557408 \ J$

On converting it in "MJ", we get

= $61.557\times 10^6 \ J$

= $61.557 \ MJ$

Answer:

actually no one weres the scarf in sunny ʕ•ε•ʔ

Explanation:

The colours we see are the wavelengths that are reflected or transmitted. For example, a red shirt looks red because the dye molecules in the fabric have absorbed the wavelengths of light from

An insect 1.1 mm tall is placed 1.0 mm beyond the focal point of the objective lens of a compound microscope. The objective lens

Pavlova-9 [17]

Answer:

Explanation:

For image formation in objective lens

object distance u = 14 +1 = 15 mm

focal length f = 14 mm .

image distance v = ?

lens formula

$\frac{1}{v} -\frac{1}{u} =\frac{1}{f}$

Putting the values

$\frac{1}{v} +\frac{1}{15} =\frac{1}{14}$

v = 210 mm .

B )

magnification = v / u

= 210 / 15

= 14

size of image = 14 x 1.1 mm

= 15.4 mm

= 15 mm approx

C )

For final image to be at infinity , image produced by objective lens must fall at the focal point of eye piece . so objective lens's distance from the image formed by objective must be equal to focal length of eye piece that is 21 mm .

21 mm is the answer .

D )

overall magnification =

$\frac{210}{15} \times \frac{D}{f_e}$

D = 25 cm , f_e = focal length of eye piece

= 14 x 250 / 21

= 166.67

= 170 ( in two significant figures )
