The speed limit in the school zone in Florida may not be less than 15 miles per hour excluding the local directive. No school zone speed limit intends to be more than 20 miles per hour in an urbanized zone as well-defined in section 334.03. The speed limit may possibly in force only all through those times 30 minutes before or during and 30 minutes after the periods of time when pupils are incoming at a regularly organized school session. Stable signs labeling school zones and school zone speed limits shall be identical in size, color and shall have the times all through which the restraining speed limit is compulsory clearly designated thereon.

Calculate the electric field strength at a point at which a test charge of 0.30 coulombs experiences a force of 5.0 newtons.
SVEN [57.7K]

The strength of electric field E is 17 N / C.

<u />

<u>Explanation:</u>

Electric field strength is defined as the force per unit charge acting at a point in the given field. The equation for the strength of the electric field is given by

                     E = F / q

where E represents the electric field strength,

           F represents the force in newton,

           q represents the charge in coulomb.

Given the charge q = 0.30 coulombs

                   force F = 5.0 N

Electric field strength E = force / charge

                                        = 5.0 / 0.30

                                    E  = 16.66 = 17 N / C.

Describe the electrical and chemical changes that lead to an action potential. Define myelin and discuss its effects.
solniwko [45]

Answer:

The outside of a neuron has more sodium ions while at resting state. When a electrical signal is going to pass through, the sodium channels open up first and the positive sodium ions rush inward making the inner side more positive. This is called action potential.

There is layer of fatty substances called as Myelin Sheath over the course of axons. It helps the electrical signal to be transmitted with a fast pace and efficiently over the course.

a 10-N force is exerted on a box, moving it 20 m in the same direction. What is the magnitude of work done on the box?
-Dominant- [34]
F = 10 N

d = 20 m

θ = 0°

W = F (dot product) D = F * D * cos(angle between them)

W = FDcosθ

W = 10 * 20 * cos0 = 200 J
