1. Coulomb's Law
Coulomb's law states that the force of a charged object on another charged object is directly proportional to the product of their charge(s) and inversely proportional to the square of the distance between them.
<em>k</em> is a constant.
2. The Force Would Decrease.
Coulomb's law predicts the electric force between two charged objects in a medium.
where K is the medium's dielectric constant.
Vacuum:
Plastic:
Therefore, the force between the two balls will decrease when the plastic sheet is inserted.
3. The Junction Rule states that the sum of magnitudes of the currents directed into a junction equals the sum of the magnitudes of the currents directed out of the current.
4. A Toroid is a doughnut shaped object whose surface is a torus. It annular shape is generated by revolving a circle around an axis external to the circle. Some example uses are RF chokes which is an inductor to have a high impedance to RF current and low impedance to DC current. Another use is variable-frequency oscillator (VFO). The frequency is set by a tuned circuit using capacitors and inductors. The frequency can be changed by adjusting the components in the tuned circuit. Just one last example is in mixers. These are used in transformers for Diode Ring Mixers. Which result in being ready, built, and homebrew.
Answer:
Physical indicates connected with, pertaining to, the animal or human body as a material organism: physical strength, exercise. Bodily means belonging to, concerned with, the human body as distinct from the mind or spirit: bodily pain or suffering.
Answer:
According to the University of Iowa, the average length of a stride is 5ft.
Now, the total distance of the marathon is:
26mi and 385yd.
Let's transform that distance into ft.
1mi = 5280ft
Then:
26mi = 26*5280ft = 137,280ft
1yd = 3ft
then:
385yd = 385*3ft = 1,155ft.
Then the total distance of the marathon, in ft, is:
D = 137,280ft + 1,155ft = 138,435 ft.
Now the average number of strides needed will be equal to the quotient between the total distance of the marathon and the distance traveled in each stride.
N = 138,435ft/5ft = 27,687.
<h2>
Answer:It is not affected by the change in media.</h2>
Explanation:
Transverse waves are those waves where the medium particles vibrate perpendicular to the direction of propagation.
Transverse waves do not require any medium.
They travel with same speed in any medium.
Electromagnetic waves are transverse waves where the medium particles vibrate perpendicular to the direction of propagation.
So,their speed is same in any medium.
