Explain why the current is reduced as electrons move through a conductor.

Answers

Answer 1
Answer:

The current is reduced as less energy is available to move electrons through the wire.


This is because electrons moving through the conducting substance collide with the electrons and ions.


This causes collisions which further more convert kinetic energy into thermal energy because of the fewer energy that is available, it reduces.


Moreover the resistivity factor of the conductor it self might play some role and the loss of energy too.
Answer 2
Answer: as current moves through the conductor; the resistance of the conductor causes the original amount of current to reduce do to the length and the cross section size of the wire.

There are some cases where distance time graph of a particle is vertical . So could you please tell me when it is possible????

Answers

-- If time is the horizontal axis and distance is the vertical axis, then it's not possible
for the particle's distance/time graph to be a vertical line.  That would indicate that
the particle covered some distance in zero time, indicating infinite speed.

-- If distance is the horizontal axis and time is the vertical axis, and the particle's
distance/time graph is a vertical line, then that indicates that the particle's distance
doesn't change with time. In other words, the particle is at rest, and its speed is zero.
when the body is in rest or in constant speed

If two swimmers compete in a race, does the faster swimmer develop more power?

Answers

Power is equal to energy per unit time. In this case, power is proportional to energy while is inversely proportional to time,on the other hand. Given the two swimmers exerts same amount of energy but the faster swimmer just does things in faster time, then the faster swimmer should develop more power from shorter time

Blue light and yellow light combine to produce white light becausea. they absorb each other s wavelengths.
b. blue, yellow, and white are primary colors.
c. they are complementary colors of light.
d. they are both primary colors of light.

Answers

Answer: The correct answer is c.

Explanation: According the RGB color model, the light of the two complementary colors will combine to form a white light. This happens because the complementary colors combine at full intensity.

Complementary colors according to RBG color model is:

  1. Red - Cyan
  2. Green - Magenta
  3. Blue - Yellow

From the above information, we conclude that blue light and yellow light are complementary colors of light and hence, the combination of two will produce white light.
Blue and yellow light combine to produce white light because they are complementary colors of lights.
When you say complementary colors, it refers to a combination of 2 colors that when mixed, they fade out their color. That's why when blue light and yellow light are combined they produces white light.

A 25 newton force applied on an object moves it 50 meters. The angle between the force and displacement is 40.0°. What is the value of work being done on the object?

Answers

The total work done is 957.56 joules. This is calculated as work is equal to 25N time 50 meters time cosine 40 degrees.

Answer:

Work being done on the object = 766.04J

Explanation:

Work done by a force  is calculated by finding dot product of force and displacement.

            W = F . s

             F = 25 N

              s = 50 m

               θ = 40.0°

W = F . s = Fs cosθ = 25 x 40 x cos 40 = 766.04J

Work being done on the object = 766.04J
