A point charge q1 = -4. 00 nc is at the point x = 0. 60 m, y = 0. 80 m , and a second point charge q2 = +6. 00 nc is at the poin

The net electric field is the vector sum of the components of the electric

field produced by the two charges.

The values of the magnitude and direction of the net electric field at the origin (approximate values) are;

131.6 N/C

12.6 ° above the negative x–axis

<h3>How are the net electric field magnitude and direction calculated?</h3>

The possible questions based on a similar question posted online are;

(a) The net electric field at the origin.

The electric field due to charge q₁ is given as follows;

$\vec E_{1x} = \mathbf{ \dfrac{1}{4 \cdot \pi \cdot \epsilon_0} \cdot \dfrac{q_1}{\vec{r}^2_2}}$

Which gives;

$\vec{E}_{1x} =\mathbf{ \dfrac{\left(9 \times 10^9 \, N \cdot m/C^2 \right) \cdot \left(-4 \, nC \times \dfrac{10^{-9}C}{1 \, nC} \right)}{\left(1 \, m \right)^2}} \cdot cos\left(arctan\left(\dfrac{0.8}{0.6} \right) \right) =-21.6 \, N/C$

$\vec{E}_{1y} = \mathbf{\dfrac{\left(9 \times 10^9 \, N \cdot m/C^2 \right) \cdot \left(-4 \, nC \times \dfrac{10^{-9}C}{1 \, nC} \right)}{\left(1 \, m \right)^2}} \cdot sin\left(arctan\left(\dfrac{0.8}{0.6} \right) \right) = 28.8 \, N/C$

Which gives;

$\vec{E}_1 = \mathbf{21.6 \, N/C \cdot \hat x + 28.8 \, N/C \hat y}$

$\vec{E}_{2x} = \dfrac{\left(9 \times 10^9 \, N \cdot m/C^2 \right) \cdot \left(6.00 \, nC \times \dfrac{10^{-9}C}{1 \, nC} \right)}{\left(1 \, m \right)^2} = 150 \, N/C$

Therefore;

$\vec {E} = \left[ 21.6 \, N/C - 150 \, N/C \right] \left( \hat x \right) + \left(28.8 \, N/C \right) \left( \hat y \right)$

$\vec {E} = \mathbf{\left( -128.4 \, N/C \right) \left( \hat x \right) + \left(28.8 \, N/C \right) \left( \hat y \right)}$

The magnitude of the net electric field is therefore;

E = $\sqrt{(-128.4^2 + 28.8^2)}$ ≈ 131.6

The magnitude of the net electric field at the origin is E ≈<u> 131.6 N/C</u>

(b) The direction of the net electric field at the origin.

$The \ direction \ is \ arctan \left(\dfrac{28.8}{-128.4} \right) \approx \underline{ 12.6^{\circ}} \ above \ the \ negative \ x-axis$

An athlete complains of weakness, rapid weight gain and muscle spasms. What may be the cause

hichkok12 [17]

The reason the athlete would have these complaints would be due to the fact that they are loaded on carbs.

<h3>What is carb loading?</h3>

This is used to refer to the fact that the athlete is taking too much of meals that are made up of carbohydrates.

Carbohydrates are heavy foods. They may cause the person to gain weight in a rapid way and also lead to weakness.

Excessively having carbs in your diets may also bring about other types of health issues such as:

A great increase in your blood sugar level.
It call lead to fat because your body would save the excess glucose as fat.
This may be one of the causes of diabetes in a person if they fail to take care of the fact that they are controlling carbs in a way that is unhealthy.
It could cause sluggishness.
For other people it may result in the outbreak of acne on their faces.

A company ordered $400 worth of muffins. Bran muffins cost $2 each and blueberry muffins cost $4 each. If the company ordered tw

astra-53 [7]

Answer:

40 Bran Muffins

80 Blueberry Muffins

Explanation:

Let the number of Bran muffins ordered = x

The number of Blueberry muffins ordered = 2x <em>(it is given that the number of blueberry muffins is twice the number of bran muffins)</em>

<em />

The cost of Bran muffins ordered = Number of Bran muffins * cost of 1 muffin

Cost of Bran muffins ordered = x * 2

Cost of Bran Muffins ordered = $ 2x

The cost of Blueberry muffins ordered = Number of Blueberry muffins * Cost of 1 blueberry muffin

Cost of Blueberry muffins ordered = 2x * 4

Cost of Blueberry muffins ordered = $ 8x

Since the sum of costs of Blueberry and Bran muffins is $400

Cost of Bran muffins + Cost of Blueberry muffins ordered = 400

2x + 8x = 400

10x = 400

x = 40

Hence, the number of Bran muffins ordered is 40

we are told that the number of Blueberry muffins is twice the number of Bran muffins

So,

Blueberry muffins = Bran muffins * 2

Blueberry Muffins = 40 * 2

Blueberry muffins = 80

So, the number of Blueberry muffins is 80
