Hi!
The perpendicular distance 2.4cm, is much less than the distance to both endpoints of the wire, which is aprox 1m. Then the edge effect is negligible at this field point, and we can aproximate the wire as infinitely long.
The electric filed of an infinitely long wire is easy to calculate. Let's call z the axis along the wire. Because of its simmetry (translational and rotational), the electric field E must point in the radial direction, and it cannot depende on coordinate z. To calculate the field Gauss law is used, as seen in the image, with a cylindrical gaussian surface. The result is:
Then the electric field at the point of interest is estimated as:
Answer: W.D = 1/2mv^2
Explanation:
If an external force or a single force is acting on a body. Just like the first law of thermodynamics, the force acting on the body will cause work done on the system.
Work done = force × distance
And the work done on the body will cause the molecules of the body to experience motion and thereby producing kinetic energy.
The work done will be converted to kinetic energy.
W.D = 1/2mv^2

2, sorry I'm late but my answer is right, I just took the quiz
Answer:
A. structure of the classroom
Explanation:
According to the Creative Curriculum model, the _ structure of the classroom_ sets the context for teaching and learning.
In creative curriculum model children learn through creative and active learning strategy. Creative curriculum are implemented through structure of classrooms. Creative curriculum stands to enhance skill of the the students and inculcate in them passion for learning.
Between g and h the object is not moving.
