]Scientists are able to construct valid scientific methods to study the formation of the solar system by beingbiased and religious
impractical and modest
imaginative and original
unreasonable and outdated

Answers

Answer 1

Answer:

Answer:

The correct answer will be option-imaginative and original.

Explanation:

The study of any natural phenomenon is based on the methods developed by humans. These methods are known as scientific methods as they approach the explanation in a systematic way.

The quest to understand the astronomical perspective-universe, planets and the planetary motions began around 2500 years ago which persists even today.

To understand the solar system researcher has to be a keen observer, imaginative and truthful to the evidence and data recorded. The logical imagination is essential to study the solar system as one is not able to see the far objects. This practicality allowed the researcher to think and rethink over the laws governing the systems.

Thus, option-imaginative and original is the correct answer.

Answer 2

Answer: Imaginative and original are the best choices here. I would not say they necessarily result in valid results, though.

Ideally, when a thermometer is used to measure the temperature of an object, the temperature of the object itself should not change. However, if a significant amount of heat flows from the object to the thermometer, the temperature will change. A thermometer has a mass of 33.0 g, a specific heat capacity of c = 804 J/(kg C°), and a temperature of 15.4 °C. It is immersed in 149 g of water, and the final temperature of the water and thermometer is 56.0 °C. What was the temperature of the water in degrees Celsius before the insertion of the thermometer?

Which of the following statements describes an electric generator?A. A magnet is rotated through a coil of wire to produce an electric current.
B. Electric potential in a rotating coil of wire creates a permanent magnet.
C. An electrical current causes a coil of wire to rotate in a magnetic field.
D. Forces from a permanent magnet allow a coil of wire to rotate.

Answers

Answer:

A. A magnet is rotated through a coil of wire to produce an electric current.

Explanation:

An electric generator works on the principle of Faraday's law of induction. As the magnetic flux linked with the coil changes, an emf is induced in the coil and current is produced.

An electric generator converts mechanical energy to electrical energy.

Thus, the correct statement that describes the an electric generator is: A. A magnet is rotated through a coil of wire to produce an electric current.

An electric generator is when a magnet is rotated through a coil of wire to produce an electric current.

Which of the following voltages would most likely be used as a primary distribution voltage by an electric utility company?a. 120 V
b. 440 V
c. 4,160 V
d. 69,000 V

Answers

Answer:

c. 4,160 V

Explanation:

Primary distribution voltage by electric utility company are often distributed around 3 Kv to 35 Kv, which would be a range between 3,000 V to 35,000 V because in order to be consumed by the public they use transformers to lower the voltage to less than 1Kv this can be used in domestic usage, so form the options the one that most likely would be used as a primary distribution voltage is 4,160 V.

The answer is D.69,000 V.

The wavelength of some violet light is 420.0 nm. what is the frequency of this violet light?

Answers

The equation relating wavelength and frequency of light is:
v = fλ; where v is the wave's speed, f is its frequency and λ is the wavelength.
The speed of violet light will be the same as for any elecromagnetic radiation, that is,
3 x 10⁸ m/s
3 x 10⁸ = f(420 x 10⁻⁹)
f = 7.14 x 10¹⁴ Hz

The frequency of light for which the wavelength is $420\,{\text{nm}}$ is $\boxed{7.14 * {{10}^(14)}\,{\text{Hz}}}$ .

Further explanation:

The frequency is a measure of number of wave’s that passes through a fixed point or place in a given time interval. The S.I unit of frequency is Hertz $\left( {{\text{Hz}}} \right)$ .

Wavelength is defined as the distance between two successive crests or troughs of a travelling wave.

Examples of waves are sound wave, light wave, mechanical waves, surface waves etc.

Given:

The wavelength of the light used is $420\,{\text{nm}}$ .

The speed of the light is $3 * {10^8}\,{{\text{m}} \mathord{\left/ {\vphantom {{\text{m}} {\text{s}}}} \right. \kern-\nulldelimiterspace} {\text{s}}}$ .

Concept:

Light is an electromagnetic wave which carries energy in the form of electric field and magnetic field. The speed of light in vacuum is $3 * {10^8}\,{{\text{m}} \mathord{\left/ {\vphantom {{\text{m}} {\text{s}}}} \right. \kern-\nulldelimiterspace} {\text{s}}}$ .

The speed of light can be expressed in terms of wavelength of the light and the frequency of the light.

The speed of light is:

$c = f \cdot \lambda$

Rearrange the above expression.

$\boxed{f=(c)/(\lambda )}$ …… (1)

Here, $f$ is the frequency of the light, $c$ is the speed of the light in vacuum and $\lambda$ is the wavelength of the light.

Substitute $3 * {10^8}\,{{\text{m}} \mathord{\left/ {\vphantom {{\text{m}} {\text{s}}}} \right. \kern-\nulldelimiterspace} {\text{s}}}$ for $c$ and $420 * {10^( - 9)}\,{\text{m}}$ for $\lambda$ in equation (1).

$\begin{aligned}f&=\frac{{3*{{10}^8}\,{{\text{m}}\mathord{\left/ {\vphantom {{\text{m}} {\text{s}}}}\right.\kern-\nulldelimiterspace}{\text{s}}}}}{{420 * {{10}^(-9)}\,{\text{m}}}}\n&=7.14* {10^(14)}\,{\text{Hz}} \n \end{aligned}$

Thus, the frequency of light for which the wavelength is $420\,{\text{nm}}$ is $\boxed{7.14 * {{10}^(14)}\,{\text{Hz}}}$ .

Which ionic compound is used as a building material?

Answers

Magnesium oxide is an ionic compound that can be used as a building material. MO2 is actually a raw material that used in producing cement for building houses, buildings, and other constructions.
Many old structures were made of limestones. Limestone is from Calcium Carbonate (CaCO3) which is an ionic compound and can be used as a building material too.

Final answer:

Ionic solids, such as sodium chloride and nickel oxide, are used as building materials due to their strong bond and high melting points. They are rigid and brittle but can conduct electricity when molten or dissolved.

Explanation:

Ionic solids, such as sodium chloride and nickel oxide, are used as building materials. These solids are composed of positive and negative ions held together by electrostatic attraction. They have high melting points, are rigid and brittle, and do not conduct electricity in their solid state.

However, they conduct electricity when molten or dissolved. Many simple compounds formed by the reaction of a metallic element with a nonmetallic element are ionic. These are crystalline compounds composed of positively charged ions and negatively charged ions held together by electrostatic forces. They have high melting points and are typically brittle.

What would happen if the moon were twice as big

Answers

The universal gravity formula is F = G(Me)(Mm)/r^2. Lets use this formula to help us calculate what would happen if the Moon was twice as big.
Mn = new mass = 2*Mm
Fn = G(Me)(Mn)/r^2
Fn = G(Me)(2Mm)/r^2
Fn = 2*G(Me)(Mm)/r^2
Fn = 2*F
So 2 times the force it was before. The force should be the same, but you never know the moon and space as well know it can work in very mysterious ways.

The force is the same force the moon pulls on the earth is the same as the earth pulls the moon
