PLEASE HELP ME Color corresponds to the ______________ of light waves. wave speed cycles wavelength

Answers

Answer 1

Answer: Wavelength. Each wavelength is a certain color. For instance, shorter wavelengths (like 470nm) will be blue or violet, while longer wavelengths (like 650nm) will be red. Hope this helps! :)

The cloud of interstellar dust and gas that forms a star is known as aA. white dwarf.
B. protostar.
C. red giant.
D. nebula.

Answers

D. nebula

Nebula is the cloud of interstellar dust and gas that forms a star. It is collborately shaped during colliding and collapsing of the interstellar mediums this is influenced by the gravitational attraction of the atoms and particles in the entites. Hence, there are three types of nebular namely, are classical nebula, diffuse nebula, planetary nebular and supernova remnants.

Radiative forcing is the amount of change in the thermal energy units (watts/square meter on the earth's surface) caused by a given factor. True or False?

Answers

Answer:

True

Explanation:

Radiative forcing is indeed the measure of the change in thermal energy units (watts per square meter) at the Earth's surface or in the atmosphere caused by a particular factor, such as an increase in greenhouse gases or aerosols. It quantifies the impact of various factors on the Earth's energy balance and is an important concept in climate science for understanding the drivers of climate change.

Two objects are dropped from rest from the same height. Object A falls through a distance during a time t, and object B falls through a distance during a time 2t. If air resistance is negligible, what is the relationship between A and B?

Answers

Answer:

Distance covered by B is 4 times distance covered by A

Explanation:

For an object in free fall starting from rest, the distance covered by the object in a time t is

$s=(1)/(2)gt^2$

where

s is the distance covered

g is the acceleration due to gravity

t is the time elapsed

In this problem:

- Object A falls through a distance $s_A$ during a time t, so the distance covered by object A is

$s_A=(1)/(2)gt^2$

- Object B falls through a distance $s_B$ during a time 2t, so the distance covered by object B is

$s_B=(1)/(2)g(2t)^2 = 4((1)/(2)gt^2)=4s_A$

So, the distance covered by object B is 4 times the distance covered by object A.

You dip your finger into a pan of water twice each second, producing waves with crests that are separated by 0.15 m. Determine the frequency, period, and speed of these water waves.

Answers

Frequency = rate of sploosh = 2 per second = 2 Hz.

Period = ( 1/frequency ) = 1/2 second

Speed = (wavelength) x (frequency) = (0.15m) x ( 2/sec) = 0.075 m/s .

In a series circuit, as more batteries are added what effect does it have on the bulbs in a circuit . Will the bulbs get brighter or stay the same?

Answers

If the batteries are in series too, then the more batteries,
the more voltage across the light bulbs, and the brighter
they will all burn.

(Until you add the battery that causes the weakest bulb
to burn out. Then they ALL go out.)
