pashok25 [27]
I think the correct answer would be that the temperature of the clouds that made the very first stars where thought to be higher since the clouds are made up of hydrogen and helium. Hope this answers the question. Have a nice day.

How do you relate and explain a planet's distance from the Sun to things like the time of their year & their average tempare
anzhelika [568]
What we call a "year" is the time a body takes to complete one orbital revolution
in its path around the sun.  The way gravity works, the farther a planet is from the
sun, the slower it moves, and the longer it takes to complete that trip.  So, farther
out from the sun means a longer "year".

Everybody knows that if you want to get more warmth, then you have to stand closer
to the fire, and it's the same with planets.  The farther a planet is from the sun, the less
heat it gets from the sun, and in most cases, that means its average temperature is
lower. (The planet's average temperature is affected by other things besides its distance
from the sun, such as how much heat comes up from inside, and how much heat its
atmosphere traps.)

The farther a planet's rotation axis is tilted from being perpendicular to the plane
of its orbit, the more seasonal variation there can be in the temperature at any one
place on its surface.  Of course, this is kind of irrelevant if the planet has no surface.

Cual es la velocidad de un atleta que se tarda 50 segundos en recorrer una pista de 400 metros
dedylja [7]

Answer:

v = 8 [m/s]

Explanation:

Debemos determinar la velocidad promedio, esta velocidad se define como la relacion entre la distancia recorrida sobre un determinado tiempo.

De esta manera tenemos la siguiente expresion:

v = x/t

donde:

v = velocidad [m/s]

x = distancia = 400 [m]

t = tiempo = 50 [s]

v = 400/50

v = 8 [m/s]

A positive charge of 6.0 x 10-4 C is in an electric field that exerts a force of 4.5 x 10 -4 on it. What is the strength of the
Yuki888 [10]

Electric field is defined as force per unit charge.

So it is given by

F = q E

now we can find electric field by

E = \frac{F}{q}

E = \frac{4.5*10^{-4}}{6 * 10^{-4}}

E = 0.75 N/C

So field strength is 0.75 N/C.
