Answer: 380 nm (violet-blue) and 780 nm (red)

Explanation:

The portion visible by the human eye of the electromagnetic spectrum is between 380 nm (violet-blue) and 780 nm (red) approximately.

This part of the spectrum is located between ultraviolet light and infrared light.

It should be noted that the fact only part of the whole electromagnetic spectrum is visible to humans is because the receptors in our eyes are only sensitive to these wavelengths.

Rocks will eventually come from other rocks as described by the rock cycle. Given this, what do you think is the type of the old

RoseWind [281]

Answer:

The Rock Cycle is Earth's great recycling process where igneous, metamorphic, and sedimentary rocks can all be derived from and form one another. The rock cycle by definition is a natural process by which sedimentary, igneous, and metamorphic rocks are created, changed from one type to another, and destroyed.

The Sedimentary Rocks is the type of the oldest rocks on Earth.

Sedimentary rocks, such as sandstone, are created by the compression of sediment or particles. ... The oldest whole rocks found so far date back about 4.28 billion years. They were found in 2001 by geologists excavating near Canada's Hudson Bay in northern Quebec, andthe research appeared in the Sept.

You are using a constant force to speed up a toy car from an initial speed of 6.5 m/s

Pachacha [2.7K]

By the work-energy theorem, the total work done on the car is equal to the change in its kinetic energy:

W = ∆K

W = 1/2 (0.34 kg) (22.9 m/s)² - 1/2 (0.34 kg) (6.5 m/s)²

W ≈ 82 J

Determine the stopping distances for a car with an initial speed of 88 km/h and human reaction time of 2.0 s for the following a

seropon [69]

Explanation:

Given that,

Initial speed of the car, u = 88 km/h = 24.44 m/s

Reaction time, t = 2 s

Distance covered during this time, $d=24.44\times 2=48.88\ m$

(a) Acceleration, $a=-4\ m/s^2$

We need to find the stopping distance, v = 0. It can be calculated using the third equation of motion as :

$s=\dfrac{v^2-u^2}{2a}$

$s=\dfrac{-(24.44)^2}{2\times -4}$

s = 74.66 meters

s = 74.66 + 48.88 = 123.54 meters

(b) Acceleration, $a=-8\ m/s^2$

$s=\dfrac{v^2-u^2}{2a}$

$s=\dfrac{-(24.44)^2}{2\times -8}$

s = 37.33 meters

s = 37.33 + 48.88 = 86.21 meters

Hence, this is the required solution.

A type O star is likely to appear

Ludmilka [50]

A type O star is likely to appear blue in color.

The blue type-O stars are solely thirty to fifty times a lot of large than the sun. However, O stars burn 1,000,000 times brighter and it has a very short lifespan. O stars solely last a couple of million years before they die in spectacular star explosions.
