Study the line graph. Based on this graph, which of the following statements are true? check all of the boxes that apply. Each y

ear from 1942 to 1944, the united states built more than double the number of ships it had built in 1941 the united states increased the number of ships it built in each year of the war. The united states built more than 2,500 ships in 1943.

Based on this line graph, the statements that are true include:

  1. A moderate level of conflict produces the highest level of performance.
  2. Teams need some conflict to do their best work.

<h3>What is a conflict?</h3>

A conflict can be defined as any form of disagreement, misunderstanding or struggle that arises between two or more parties such as members of a team, as a result of any one of the following;

  • An incompatibility
  • A challenge
  • Differing opinions
  • An opposing view
  • Superiority

In this scenario, the number of ships (performance) that were built by a team in the United States of America during each year of the war were graphically represented.

Based on the line graph, we can deduce the following statements:

  1. The highest level of performance was produced by a moderate level of conflict.
  2. In order for the teams to do their best work or demonstrate the highest level of performance, they need some conflict.

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
Alekssandra [29.7K]

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

What is a major division between gravity and the electromagnetic force on one hand and the nuclear forces on the other?(1 point)
Hatshy [7]

Gravity is force present between masses while electromagnetic forces are found between charges.

Nuclear forces are short range while electromagnetic forces are long range.

<h3>Electromagnetic force Vs Nuclear force</h3>

Nuclear force are short ranged while electromagnetic forces cover a wider range, it is dependent on the charges present. Unlike charges attract each other while like charges repel each other in electromagnetic forces.

Nuclear forces occur in the nucleus of an atom and it an attractive force. unlike electromagnetic forces nuclear force do not repel.

Hence we can conclude that ; Gravity is force present between masses while electromagnetic forces are found between charge and Nuclear forces are short range while electromagnetic forces are long range.

How does gravity influence our solar system?? Claim evidence reasoning
Elis [28]

Answer:

The Sun's gravity pulls the planets in orbit around it, and some planets pull moons in orbit around them. Even spacecraft are in motion through the solar system, either in orbit around the Earth or Moon, or traveling to further worlds, because of gravitational forces.
