Answer:

<em>C) only No. 2 is true.</em>

Explanation:

There are actually 4 main types of DC motors. Namely Series, Shunt, and Compound and Permanent Magnet DC Motors.

The permanent motor magnet requires a permanent magnet to generate flux of field. This form of DC motor offers excellent initial torque and strong speed control, however power is restricted so they are usually used in applications with low horsepower rates.

What is the energy of photons emitted by the led at a frequency of 610 thz mcat?
Ksju [112]

The photon energy is the energy carried by a single proton.

The equation used for calculating photon energy is:

E = hc / λ

where h = Planck constant 

c  = speed of light and

λ = wavelength of photon

frequency = f = c / λ

replace c /λ with f in the equation of photon energy

E = hf

frequency = 610 thz = 6.1 x 10¹⁴hz

h = 6.26 x 10⁻³⁴ js

E = 6.26 x 10⁻³⁴ x 6.1 x 10¹⁴

<span>E = 3.8 x 10</span>⁻¹⁹ j

Which unit of measurement should be used for the vertical axis? A. kg B. cm C. mL D. s
forsale [732]

Without knowing what kind of data you're trying to show on the graph,
and without knowing what 'kg', 'cm', 'mL', or 's' actually mean, it's really
hard to make any recommendation.
