Answer:

data table and line graph

Explanation:

The data table would consist of the amount of fiber that a student consumes in one column and the grade of the student. So, here the independent variable is amount of fiber that a student consumes and the dependent variable is the grade of the student. The x axis of the graph represents the amount of fiber that a student consumes and the y axis represents the grade of the student.

The line in a graph represents the relationship between the variables of the graph.

A ray of light is moving from a material having a high indexof refraction into a material with a lower index of refraction.
Crazy boy [7]

Answer:

Away from the normal

Explanation:

The direction toward which the ray of light bend can be found by using Snell's law:

n_1 sin \theta_1 = n_2 sin \theta_2

where

n1, n2 are the index of refraction of the first and second medium

\theta_1, \theta_2 are the angle of the incident and refracted ray with respect to the normal to the surface

Here, the ray of light moves from a material with high index of refraction to a material with lower index, therfore we have

n_1 > n_2

Re-arranging Snell's equation we get

sin \theta_2 = \frac{n_1}{n_2} sin \theta_1

and since

\frac{n_1}{n_2}>1

we find

sin \theta_2 > sin \theta_1\\\theta_2 > \theta_1

which means that the ray of light bends away from the normal.

Suppose you wish to construct a motor that produces a maximum torque whose magnitude is 1.7 × 10-2 N·m. The coil of the motor ha
Len [333]

Answer:

86 turns

Explanation:

Parameters given:

Magnetic torque, τ = 1.7 * 10^(-2) Nm

Area of coil, A = 9 * 10^(-4) m²

Current in coil, I = 1.1 A

Magnetic field, B = 0.2 T

The magnetic toque is given mathematically as:

τ = N * I * A * B

Where N = number of turns

To find the number of turns, we make N subject of formula:

N = τ/(I * A * B)

Therefore:

N = (1.7 * 10^(-2)) / (1.1 * 9 * 10^(-4) * 0.2)

N = 85.85 = 86 turns (whole number)

The number of turns must be 86.

Tarzan and Jane. Because of your concern that incorrect science is being taught to children when they watch cartoons on TV, you
creativ13 [48]

Answer:

The maximum height Tarzan and Jane can swing as a fraction of her initial heigh is ⅓h

Explanation:

Let

m = Mass of Tarzan

M = Mass of Jane

Given

M = 2m

To calculate the maximum height Tarzan and Jane can swing, we make use of the potential energy at their initial and final position.

Reason being that;

At both the initial and final position, velocity is 0, so there's no kinetic energy.

And the potential energy remains the same (i.e constant) at any given point in the system.

Using P.E = mgh.

At initial position, PE1 = mgh

At final position, PE2 = (m + M)gH.

Where h and H represent the initial and final heights.

m + M is the new weight after Jane and Tarzan swing

Equating PE1 to PE2

mgh = (m + M)gH

By substituton (M = 2m)

mgh = (m + 2m)gH

mgh = 3mgH

Make H the subject of the formula

H = mgh/3mg

H = ⅓h

Hence, the maximum height Tarzan and Jane can swing as a fraction of her initial heigh is ⅓h

From the question, the new height looks to be about ½ that of Jane's original position; i.e. ½h

The calculated height is smaller than what the cartoon is showing;

We can conclude that the cartoon is wrong.
