1) The astronaut's sense of imbalance in a space flight is due to the rotation of a device in which he or she feels a fictitious

gravity that mimics gravity. The the device rotates according to the mathematical equation: n =g^0.5/2πr^0.5 Where n is the rotational speed and is measured in rotations per second (s). (r) is the radius of the circulator and is measured in meters (m). (g) is a simulation of gravity. Calculate the rotation speed of a device, that has a radius of 1.7 meters and rotates to simulate the gravitational force which equals to: g = 9.8 m/s^2 with steps please

Answer:

n = 0.38 rotation per second

Step-by-step explanation:

The device rotates according to the mathematical equation :

n=\dfrac{g^{0.5}}{2\pi r^{0.5}} ...(1)

Where n is the rotational speed and is measured in rotations per second (s).

r is radius of the circulator and is measured in meters (m).

We need to find the rotational speed when radius is 1.7 m. Put r = 1.7 m in equation (1).

n=\dfrac{(9.8)^{0.5}}{2\pi \times (1.7)^{0.5}}\\\\=0.38\ \text{rotations per second}

Hence, the rotational speed is 0.38 rotation per second.

it's asking to write an equation in slope-intercept form for the line with slope -4 and y-intercept 7. then graph the line. plea
LuckyWell [14K]

Answer:

Equation = y = -4x+7

See the graph below

Step-by-step explanation:

The equation of the line in slope intercept form is expressed as;

y = mx+c

Given

slope m = -4

y-intercept c = 7

Substitute

y = -4x + 7

Get the x intercept.

at y = 0

0 = -4x + 7

4x = 7

x = 7/4

x = 1.75

The x coordinate  (1.75, 0)

Get the y intercept

at x = 0;

y = -4(0)+7

y = 0+7

y = 7

The y coordinate is (0, 7)

If AB=BC=CD what is the area of the green region? please show full workings ​
Romashka-Z-Leto [24]

The area of the green region is of:

9 units².

<h3>How to obtain the area of the green region?</h3>

The base is composed by three equal segments, hence their lengths are given as follows:

AB = BC = CD = 9/3 = 3.

The heights are given as follows:

  • B = 2.
  • C = 4.
  • D = 6.

As they are proportional.

The green region is composed by:

  • A rectangle of dimensions 3 and 2.
  • A right triangle of sides 3 and 2.

The area of the rectangle is given by the multiplication of the dimensions, hence:

Ar = 3 x 2 = 6 units².

The area of the triangle is given by half the multiplication of the dimensions, hence:

At = 0.5 x 3 x 2 = 3 units².

Then the area of the green region is given by:

A = Ar + At = 6 + 3 = 9 units².
