Oceanic electric fields produce electric currents. True False

The wavelength of the visible range of the electromagnetic spectrum lies between .

Further Explanation:

The Electromagnetic spectrum is the complete range of the electromagnetic radiation which expresses all the radiation starting from the Gamma rays to the radio waves. The electromagnetic spectrum is the detailed spectrum that explains all the electromagnetic radiations.

The electromagnetic radiations are the transverse waves which do not require any medium for their propagation. The electromagnetic waves can easily travel through space. All the electromagnetic radiations travel at the speed of light.

The different radiations in the electromagnetic spectrum are as follows:

• Gamma rays

• X-rays

• Ultraviolet rays

• Infrared rays

• Micro waves

• Radio waves

The wavelength and the frequency ranges for the different electromagnetic radiations is as shown in figure attached.

Therefore, the wavelength of the visible range of the light in the electromagnetic spectrum is .

Explanation:

Visible light is a very part of electromagnetic spectrum. We can see the visible region of the electromagnetic spectrum.

The frequency and the wavelength has an inverse relationship.

For example, the red light has large wavelength and low frequency. Violet has a short wavelength and higher frequency.

The frequency range of visible region is from 400 nm to 700 nm.

Answer: B. The total mass remains the same during a chemical reaction.

Explanation:I Took The Test.

Astronomers give stars names so that they're able to identify and keep track of them more easily.

Answer;

C.It is the minimum amount of material needed to sustain a fission reaction.

Explanation;

-A critical mass is the smallest or the minimum amount of fissile material needed for a sustained nuclear chain reaction. A critical mass must be achieved in order for the chain reaction to continue and release the atomic energy. A critical mass is needed for both a nuclear reactor and an atomic or hydrogen bomb.

-The critical mass of a fissionable material depends upon its nuclear properties (specifically, the nuclear fission cross section), its density, its shape, its enrichment, its purity, its temperature, and its surroundings.

The correct answer for above statement is:

c.It is the minimum amount of material needed to sustain a fission reaction.

Explanation:

A nuclear reaction is taken into account to be the method during which 2 nuclear paticles (two nuclei or a nucleus and a nucleon) move to supply 2 or a lot of nuclear particles or gamma rays.

Thus, a natural action should cause a change of a minimum of one nuclide to a different. typically if a nucleus interacts with another nucleus or particle while not dynamic the mature of any nuclide, the method is mentioned a nuclear scattering.

The important mass is that the smallest amount of fissile material required to sustain nuclear reactions below expressed conditions

Answer: B.

Explanation:

When we talk about projectile motion, we have to deal with parabolic motion, which has two components: vertical and horizontal.

In the case of Earth, the acceleration is due gravity, which is constant and directed downwards (vertically) and have a value of .

Now, in the case of the horizontal component, the acceleration will always be zero.

This is because we are dealing with parabolic movement, the x-component of the velocity remains the same (hence, there is no acceleration), while the y-component always change because it is affected by the acceleration due gravity that acts verticaly.

Answer:

87.5 mi/hr

Explanation:

The formula is A=Vf-Vi / t.

Final answer:

The final speed of the car after 5.0 seconds, given a starting speed of 50 mi/hr and an acceleration of 7.5 mi/hr/s, would be 87.5 mi/hr.

Explanation:

This problem involves calculating the final speed of a moving object given its initial speed, acceleration and time. Acceleration is defined as the change in velocity divided by the time taken(s). Given that the car accelerates from 0 to 60 mi/hr in 8 seconds, it means its acceleration is (60mi/hr - 0mi/hr) / 8s = 7.5 mi/hr/s. Now, if the car's starting speed were 50mi/hr, its final speed after 5.0 seconds would be calculating using the formula Final Speed = Initial Speed + (Acceleration * Time). Plugging in our values we get Final Speed = 50mi/hr + 7.5mi/hr/s * 5s = 87.5 mi/hr.
