Chips labeled 1 through 25 what is the probability of 2 or more students getting the same number
qwelly [4]
The odds of two students getting the same number, regardless of which number the first student gets, is 1:25. The odds of them getting the same number--such as both of them getting 13--would be 25*25=1:625. These are the same odds of three students getting the same numbers in a row without considering which number they get in a row. Then, if you add another student, just multiply the previous answer by 25.

Hello! I need help with this problem thanks!!
Helen [10]

Answer:

10 tomato plants and

15 rose plants

Step-by-step explanation:

Let t be the no. of tomato plants,

And r the no. of rose plants

t + r = 25

t + 2r = 40

t = 25 - r

25 - r + 2r = 40

r = 15

t = 25 - 15

t = 10

Find the magnitude of the net electric field at the origin (created by charges q1 and q2).
Readme [11.4K]

The direction of the net magnetic field is $167.36^{\circ}$

<h3>How to find the magnitude?</h3>

q_1=-4 \mathrm{nC} \text { at }(0.6,0.8)

$q_2=6 \mathrm{nC}$ at (0.6,0)

$r_1=$Distance of $q_1$ from origin$=\sqrt{0.6^2+0.8^2}$

$r_2=$ Distance of $q_2$ from origin $=0.6$

$\mathrm{k}=$ Coulomb constant$=9times 10^9 \mathrm{Nm}^2 / \mathrm{C}^2$

Electric field is given by

&E_1=\frac{k q_1}{r_1^2} \\

&\Rightarrow E_1=\frac{9 \times 10^9 \times 4 \times 10^{-9}}{\sqrt{0.6^2+0.8^2}} \\

&\Rightarrow E_1=36 \mathrm{~N} / \mathrm{C}

&\theta=\tan ^{-1} \frac{0.8}{0.6} \\

&\Rightarrow \theta=53.13^{\circ} \\

&E_1=36 \cos 53.13^{\circ} \hat{i}+36 \sin 53.13^{\circ} \hat{j} \\

&\Rightarrow E_1=21.6 \hat{i}+28.8 \hat{j}

&E_2=\frac{k q_2}{r_2^2} \\

&\Rightarrow E_2=\frac{9 \times 10^9 \times 6 \times 10^{-9}}{0.6^2} \\

&\Rightarrow E_2=150 \mathrm{~N} / \mathrm{C}

The charge $q_2$ is on the $\mathrm{x}$ axis itself and it is pointing towards the origin (left side) so the sign will be negative

E_2=-150 \hat{i}

Resultant electric field

&E=E_1+E_2 \\

&\Rightarrow E=21.6 \hat{i}+28.8 \hat{j}+(-150 \hat{i}) \\

&\Rightarrow E=-128.4 \hat{i}+28.8 \hat{j}

Magnitude of electric field is given by

&|E|=\sqrt{(-128.4)^2+28.8^2} \\

&\Rightarrow|E|=121.6 \mathrm{~N} / \mathrm{C}

Magnitude of the net electric field is $121.6 \mathrm{~N} / \mathrm{C}$

Direction is given by

\theta=\tan ^{-1} \frac{128.4}{28.8}=77.36^{\circ}

From the -x axis

(90+77.36)^{\circ}=167.36^{\circ}

The direction of the net magnetic field is $167.36^{\circ}$

The circle graph shows the results of an employment survey of 900 people. How many of the people surveyed are employed part time

There is certainly less that 900 people... but the circle is not here.
