A.900 watts That would be your correct answer
<span>The correct answer is: Mechanical Energy
Explanation:
As the guitar strings are plunked, the potential energy stored in the strings has an ability to make them vibrate. When the strings are vibrating, that potential energy is actually converted to the kinetic energy. Hence, the whole phenomena contains both the kinetic energy and the potential energy. The sum of kinetic energy and the potential energy is called Mechanical energy. Therefore, the correct answer is Mechanical Energy.</span>
Answer:
The free body diagram of John is shown in the attached figure (in the FBD john's mass is supposed to be concentrated at his center of mass and FBD is made of center of mass)
b) As shown in the FBD the ground reaction forces are:
i) In X direction 
ii) In Y direction 
c) The respective accelerations in x and y direction's is calculated by newton's second law as indicated under
Neutron Stars. Hope this helps!!
Answer:
1. Option B
2. Option C
3. Option D
4. Option C
5. Option C
Explanation:
Given the following questions:
<u>Question one:</u>
Your answer is option B, a position time graph is one of the most common graphs to use to describe the motion of objects. The vertical line of the position time graph is the line that would be the y axis in some math cases. This line represents the "position of the object" or option B.
<u>Question Two:</u>
Your answer is option C or a "distance-time graph." The vertical axis shows the distance travels, while the horizontal line shows the time the object spends in the air. Distance-time graphs are used to show the distance an object traveled, in a certain amount of time.
<u>Question three:</u>
Your answer is option D or "shortest distance between two positions." Displacements definition is purely moving something from its initial position. Displacement is also seen as length and distance, which is why the shortest distance between two positions would be considered as true when it comes to displacement.
<u>Question four:</u>
Horizontal line would be the x-axis on a normal coordinate plane, since this is a distance-time graph and the horizonal line represents time. The answer will be option C or "object is accelerating." Since a distance-time graph shows how far an object goes in a certain amount of time, the horizontal line shows how fast the object is moving while traveling that distance within that certain amount of time.
<u>Question five:</u>
Your answer is option C or "X-axis: Time; Y-axis: Displacement." Since we are talking about a displacement-time graph, Y-axis is the dependent variable, it is what's being measured, so that would be displacement. While x-axis is the independent variable, which is what is being tested, so the x-axis will be time.
Hope this helps.
