The speed of light in a vaccum is 182,282 miles per second. Light travels through space over a period of time to reach the earth. When a new star becomes visible it means that a star's light has finnaly reached us. It takes the sun's light an average of 8 minutes and 20 seconds to reach earth. Hope this helps.

I think this is the best way to explain it
light from the sun takes 8 minutes and 20 seconds to travel to Earth. So it would be the same if the Earth's light to travel to the sun. The sun is described to be a star.

Darya [45]

Answer:

Where is the text?

Explanation:

If you refer to the short sentence you wrote as text, I believe the answer is probably the word "crashes" because it shows how the momentum was transferred.

a balloon rubbed against denim gains a charge of -8.0 x 10^-6 c. What is the electric force between the balloon and the denim, w
DedPeter [7]

Answer:

230.4 N

Explanation:

Applying,

F = kqq'/r²..................... Equation 1

Where F = Electric force, k = Coulomb's constant, q = charge in the ballon, q' =  charge in the denium, r = distance between the charges.

From the question,

Given: q = -8.0×10⁻⁶ C, q' = +8.0×10⁻⁶ C, r = 0.05 m

Constant: k = 9×10⁹ Nm²/C²

Substitute these values into equation 1

F = (9×10⁹×8.0×10⁻⁶×8.0×10⁻⁶ )/0.05²

F = (576×10⁻³)/0.0025

F = 230.4 N.

8. Radioactive isotopes, differentiation of Earth’s iron core, gravity-driven compression,and meteoric bombardment all caused ea
Olegator [25]

Answer:

option C

Explanation:

the correct answer is option C.

All the activity such as Radioactive isotopes, differentiation of Earth’s iron core, gravity-driven compression,and meteoric bombardment will make the earth hotter than what it is at present.

Radioactive isotope  whose nuclei are unstable dissipate excess energy.

Differentiation of iron core means formation of into layer which includes iron.

meteorite bombardment will affect the atmosphere of the earth which protect harmful radiation.

All these activity will make earth hotter

A 12 oz can of soda was left in a car on a hot day. in the morning, the soda temperature was 60°f with a gauge pressure of 40 ps
enot [183]
From gas equations
PV/T = Constant

Then
P1V1/T1 = P2V2/T2, but V1 = V2

Therefore,
P1/T1 = P2/T2
P2 = (P1T2)/T1

P1 = 40 psi
T1 = 60°F = 288.706 K
T2 = 90°F = 305.372 K

Substituting;
P2 = (40*305.372)/288.706 = 42.31 psi

Then, gauge pressure would read 42.31 psi.

Compared to yellow light,orange light has
ArbitrLikvidat [17]
<span>So we wonder how can we compare yellow and orange light. Light is a small art of electromagnetic spectrum which is a continuum of all electromagnetic waves arranged by wavelenght and frequency. So on the EM spectrum orange has greaterr wavelangth than yellow but smaller frequency because wavelength and frequency are connected by the equation: c=f*lambda, where lambda is the wavelength and c is the speed of light and f is the frequency. We see that the higher the frequency the smaller the wavelength and vice versa.</span>
