Explanation:
Remark
Two resistances in series has the form of
Rs= C1 + C2
Two resistances is parallel has the form of
Rp = (C1 *C2)/(C1 + C2)
The plan is to first of all find C1*C2 and use this information and C1 + C2 to find the individual resistances.
Givens
Rs = 36 ohms
Rp = 8 ohms
Solution
Rp = C1 * C2/(C1 + C2)
Rp = 8 ohms
C1 + C2 = 36 ohms
8 = C1*C2 / 36 Multiply by 36
8* 36 = C1*C2
C1*C2 = 288
Use Rs to solve for C1
(36 - C2) * C2 = 288
36*C2 - C2^2 =288 Multiply by - 1
-36C2 + C2^2 = -288 Add 288 to both sides
C2^2 - 36C2 + 288= 0 Factor this equation
(C2 - 12)(C2 - 24)
C2 - 12 = 0
C2 = 12
C2 - 24 = 0
C2 = 24
<em> </em>
C2 = 24 or
C2 = 12
C1 = 36 - C2
C1 = 36 - 24 = 12
C1 = 36 - 12 = 24
Answer
<u><em>C1 = 12 ohms or 24 ohms</em></u>
<u><em>C2 = 24 ohms or 12 ohms</em></u>
Answer:
ray optics and wave optics. Here's the complete question
Although the transmission of light, and electromagnetic radiation generally, is correctly described by wave (physical) optics, there are situations for which ray (geometric) optics gives a sufficiently good approximation. For each of the situations described in the following, determine whether ray optics may be used or wave optics must be used.
50% part (a) Green laser light of wavelength 530 nm is incident on a 26-cm diameter mirror.
50% part (b) Red laser light of wavelength 722 nm is incident on a molecule of size 114 nm.
Explanation:
a) the answer is ray optics because when the mirror which is a macroscopic object interacts with the green laser light, a part of the light will be reflected by the mirror and the other part will be transmitted. mirror,lenses are examples of objects that deal with ray optics and they are based on rectilinear propagation of light.
b) the answer is wave optics because it will interfere with the light emitted by the red laser light and the molecule size is very minute. wave optics deals with interference, polarization, diffraction,, and other phenomena for which the ray approximation of geometric optics is not valid.
Answer:
Waves
Waves can be described as oscillations or vibrations about a rest position. For example:
sound waves cause air particles to vibrate back and forth;
ripples cause water particles to vibrate up and down.
The direction of these oscillations is the difference between longitudinal and transverse waves.
Longitudinal waves
A longitudinal wave is one in which the vibrations of the particles are parallel to the direction in which the energy of the wave travels.
Demonstrating longitudinal waves
Longitudinal waves show areas of compression and rarefaction:
compressions are regions of high pressure due to particles being close together.
rarefactions are regions of low pressure due to particles being spread further apart.
An accelerating electric charge will emit transverse electromagnetic waves. These waves are propagating away in wave fronts that become flatter and flatter as getting further from the source. So they will start to resemble a plane wave
I'd say if there is less force applied than there was less movement.
