Newton approximated motion in a circle as a series of linear motions, as in the polygon below.

mojhsa [17]

The answer is the option 3. (the arrow aimed to the center of the polygon)

Why?. Because the particle changed the direction of its movement due to a force inclined respect the motion and aimed to the center. Take in account that the vectors net force and acceleration are parallel.

Answer:

$A=376.99\ cm^2$

Step-by-step explanation:

We need to find the lateral surface area of the cylinder of radius 6 cm and height of 10 cm.

We need to find the lateral surface area of the cylinder. The formula for the lateral surface area of a cylinder is given by :

$A=2\pi rh\\\\A=2\pi \times 6\times 10\\A=376.99\ cm^2$

So, the lateral surface area of the cylinder is $376.99\ cm^2$ .

Vector u has initial points at (21,12) and it’s terminal point at (19,-8). Vector v has a direction opposite that of u. Who’s ma

8_murik_8 [283]

The correct form of vector v expressed as a <em>linear</em> combination of the <em>unit</em> vectors i and j is $\vec v = 10\,\hat{i} + 100\,\hat{j}$ .

<h3>What is the value of a vector with respect to another vector?</h3>

First, we need to determine the value of the vector u by subtracting two vectors whose <em>initial</em> points are at the origin:

$\vec u = (19\,\hat{i} - 8\,\hat{j}) - (21\,\hat{i} + 12\,\hat{j})$

$\vec u = - 2\,\hat{i} - 20\,\hat{j}$ (1)

According to the statement, vector v is antiparallel to vector u and its magnitude is five times as the magnitude of vector v, which means that (1) must be multiplied by two scalars:

$\vec v = - 1 \,\cdot \, 5\cdot \vec u$ (2)

Please notice that antiparallelism is represented by the scalar - 1, whereas the dilation is represented by the scalar 5.

$\vec v = 10\,\hat{i} + 100\,\hat{j}$

The correct form of vector v expressed as a <em>linear</em> combination of the <em>unit</em> vectors i and j is $\vec v = 10\,\hat{i} + 100\,\hat{j}$ .

<h3>Remark</h3>

The statement presents typing mistakes, correct form is shown below:

<em>Vector u has initial points at (21, 12) and its terminal point at (19, - 8). Vector v has a direction opposite that of u, whose magnitud is five times the magnitud of v. Which is the correct form of vector v expressed as a linear combination of the unit vectors i and j?</em>

Two angles are supplementary. Angle A is 4x degrees. Angle B is (2x + 30) degrees. Determine the measure of each angle. Be sure

Marina86 [1]

Answer:

Angle A = 100°

Angle B = 80°

Step-by-step explanation:

Supplementary angles means angles add up to 180°.

There are only two angles given here.

Angle A and Angle B add up to 180°.

A + B = 180°

4x + (2x + 30) = 180°

4x + 2x + 30 = 180°

6x + 30 = 180°

6x = 180 - 30

6x = 150°

x = 150 ÷ 6

x = 25°

Now substitute the x value to the angles.

Angle A:

4(25) = 100°

Angle B:

2x + 30

2(25) + 30

50 + 30 = 80°
