The material used before doubling will produce light at a frequency of 0.056 Hz.

<h3 /><h3>What is the frequency?</h3>

The number of times a wave occurs repeatedly in a second is known as frequency.

The formula provides the frequency as,

$\rm v = \lambda \times f \\\\\ \rm f = \frac{v}{\lambda} \\\\ \rm f = \frac{3 \times 10^8}{532 \times 10^-9} \\\\ \rm f = 3 \times 10^{12} \\\\ f= 0.056 \ Hz$

Therefore, the material used before doubling will have an output light frequency of 0.056 Hz.

To learn more about the frequency refer to:

Which of the following objects will have the greatest inertia?

max2010maxim [7]

Answer:

The proximate answer pertaining to your question entails 10 kg.

Justification:

The statement implies which of the following units preceded by the value of 10 will obtain substantial inertia.

Exploiting conversions, this can be evinced/demonstrated:

Choice "10 m" => .01 kg

10 J ==> 0.10

10 N ==> 1.02 kg

10 kg ==> 10 kg

Thus, an object obtaining a cumulative mass of 10 kg obtains substantial inertia.

A heat pump has a coefficient of performance that is 60% of the Carnot heat pump coefficient of performance. The heat pump is us

Nataliya [291]

Answer:

$T_C$ =118.8 K= 154.2°C

Explanation:

COP_max of carnot heat pump= $\frac{T_{H} }{T_{H}-T_{C} }$

where T_H and T_C are temperatures of hot and cold reservoirs

Also COP= $\frac{Q_H}{W}$

in the question $COP= \frac{60}{100} \times COP_{max}$

⇒ $\frac{Q_H}{W} =\frac{60}{100}\times\frac{T_H}{T_H-T_C}$

heat is added directly to be as efficient as via heat pump

$Q_H= W$

and T_H= 24° C= 297 K

$1=\frac{60}{100}\times \frac{297}{297-T_C}$

on calculating the above equation we get

$T_C$ =118.8 K

the outdoor temperature for efficient addition of heat to interior of home

$T_C$ =118.8 K= 154.2°C

Which of the following provides evidence that there must be at least two types of electrical charge, but that there is only one

polet [3.4K]

Answer:

Option D (On the...............dominate) would be the right approach.

Explanation:

The Gravitational constant (G) will be:

= $6.67\times 10^{-11}$

The Coulomb's law constant (K) will be:

= $9\times 10^9$

Throughout particular, these have been determined that among 2 substances with almost the similar form of charge, the combination of electromagnetic as well as the force does seem to be usually the following:

⇒ $\frac{f_e}{f_g}\sim 10^{42}$

By that same argument, the electrostatic force including its planet's atmosphere would have strongly influenced the effect, as well as maybe the planet's atmosphere, would have crashed, or perhaps the earth would have shifted at a much longer exposure from one another and.
Throughout particular, astronomical distance statutory framework that gravity seems to be predominant, whereas electrostatic forces have been generally ignored. It is quite since there are so many categories of allegations throughout the planet's atmosphere that balance out someone else's effects, there's only yet another form of momentum, because although the forces are still cumulative, as well as therefore offering to help everything hold to the universe, encouraging the universe just to rotate across the sun.

The latter three choices aren't connected to either the situation mentioned in the clarification segment elsewhere here.
