Answer:
B.
The form of energy that travels as electromagnetic waves.
Explanation:
Light energy, or electromagnetic field energy, is the form of energy that travels as electromagnetic waves. These waves do not need a medium through with to travel, so they are able to travel through the vacuum of outer space. Some types of light can be sensed by the human eye.
Hello there. For one, they are usually very good conductors of electricity. And they are good conductors of heat too. These should be your 2 main characteristics. :)
The distance between the charge and the source of the electric field is 2.2 m.
<h3>Relationship between potential energy and Distance:</h3>
The distance of charge from the source is directly proportional to the potential energy.
Where,
- distance
- potential energy = 75 J
- Electric field =
- charge =
Put the values in the formula,
Therefore, the distance between the charge and the source of the electric field is 2.2 m.

The correct answer to this question is <span>48.8N</span><span> on a bearing of </span><span>134.2 degrees.
In order to solve this, first we need to find the resultant force of the men pulling in the north and south directions:
F = 40 - 6 = 34N [due south - 180]
Then, find the resultant force.
R^2 =34^2 + 35^2
R^2 = 2381
R = sqrt(2381)
R = 44.8N
The angle from the vertical is given by:
tan(x) = 35/34
tan(x) = 1.0294
angle = 45.8 degrees
Taking N as zero degrees, then it bears 134.2 degrees.

Answer:
Between 2.0 s and 4.0 s (B and C)
Between 5.0 s and 8.0 s (D and E)
Between 10.0 s and 11.0 s (F and G)
Explanation:
The graph shown in the figure is a velocity-time graph, which means that:
- On the x-axis, the time is plotted
- On the y-axis, the velocity is plotted
Therefore, this means that the object is not moving when the line is horizontal (because at that moment, the velocity is constant, so the object is not moving). This occurs in the following intervals:
Between 2.0 s and 4.0 s (B and C)
Between 5.0 s and 8.0 s (D and E)
Between 10.0 s and 11.0 s (F and G)
From the graph, it would be possible to infer additional information. In particular:
- The area under the graph represents the total distance covered by the object
- The slope of the graph represents the acceleration of the object
