A mouse runs along a baseboard in your house. The mouse's position as a function of time is given by x(t)=pt2+qt, with p = 0. 40

Gelneren [198K]

The average speed between t = 1.0 s and t = 4.0 s will be 2.1+0.3 which is 2.4m/s

<h3>Velocity function </h3>

Given the equation for the position of the mouse expressed as:

$x(t)=pt^2+qt\\$

The velocity of the particle is expressed as:

$v(t)=2pt+q$

Given that p = 0. 40 m/s and q = -1. 10 m/s, the equation will become:

$v(t)=2(0.4)t-1.10\\v(t)=0.8t - 1.10$

If the time is <em>t = 1.0 s, the velocity will be:</em>

$v(1) = 0.8 - 1.10\\v(1) = -0.3m/s$

Similarly if t = 4.0ssec, hence:

$v(4) = 3.2 - 1.10\\v(4) = 2.1m/s$

The average speed between t = 1.0 s and t = 4.0 s will be 2.1+0.3 which is 2.4m/s

Which function is shown in the graph? mc001-1. Jpg mc001-2. Jpg mc001-3. Jpg mc001-4. Jpg.

Elan Coil [88]

The function shown in the graph in the image attached below is $y=|x-4|$ .

<u>Given the following data:</u>

Points on the x-axis = (0, 4)

Points on the y-axis = (0, 4)

First of all, we would determine the slope of this line by using the following formula;

$Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}$

Substituting the points into the formula, we have;

$Slope. \;m = \frac{4 - 0}{4 - 0}\\\\Slope. \;m = \frac{4}{4}\\\\$

Slope, m = 1

Next, we would find the intercept:

Let x = 0, for the y-intercept.

$y=mx+b\\\\4=1(0)+b$

b = 4

Therefore, the function shown in the graph in the image attached below is $y=|x-4|$

considering periodic trends, valence electrons in which of the following atoms experience the greatest effective nuclear charge

Anni [7]

The <em>effective nuclear charge</em> is the difference between the atomic number an element and the shielding constant. Hence, the atom which experiences the greatest nuclear charge is Sulphur, S.

<u>Calculating the greatest effective nuclear charge</u>, :

$Z_{eff} = Z - S$

Z = Atomic number ; S = shielding constant

<u>For Magnesium, Mg</u>:

Z = 12

S = 10

$Z_{eff} = 12 - 10 = 2$

<u>For Aluminium, Al</u>:

Z = 13

S = 10

$Z_{eff} = 12 - 10 = 3$

For Sulphur, , S:

Z = 16

S = 10

$Z_{eff} = 16 - 10 = 6$

Therefore, the atom whuch experience the greatest $Z_{eff}$ is Sulphur.
