8 0

<span>A visible satellite images records reflected wavelengths from Earth's surface.
</span>
Visible satellite images<span> record visible light coming from the sun that is reflected by clouds, land, oceans or snow and ice.
There is a big difference between visible and infrared images since visible images record reflected light rather then emitted radiation.</span>

As the ambulance got closer, Marge noticed that the pitch of the siren got higher. This happened because

Neko [114]

Explanation :

As the ambulance got closer, Marge noticed that the pitch of the siren got higher. This is due to the Doppler's effect.

The siren of the ambulance has a higher pitch when it approaches Marge. When the waves move away from him, it will have a lower pitch.

As the waves come closer to us, the waves become compressed and hence the frequency of the wave increases.

who brought astronomy out of the dark ages by declaring: "finally we shall place the sun himself at the center of the universe.

solong [7]

Nicolaus Copernicus was the one who brought astronomy out of the dark ages.

In one of his books "On the Revolutions of the Heavenly Bodies", he published the renowned line which declares his theory.

Nicolaus Copernicus, A polish astronomer put forward the theory that the is th Sun one that rests in the middle or center of the Universe and the planet Earth revolves around it on its axis every day.which was considered to be called the Heliocentric system.

One object has a charge of +5.0 · 10-6 c, and a second object has a charge of +2.0 · 10-6

ruslelena [56]

The electrostatic force between two charged objects is given by
$F=k \frac{q_1 q_2}{r^2}$
where
k is the Coulomb's constant
q1 is the charge of the first object
q2 is the charge of the second object
r is the separation between the two objects

In our problem:
$q_1=+5.0 \cdot 10^{-6} C$
$q_2 = +2.0 \cdot 10^{-6} C$
$r=0.5 m$
So if we plug these numbers into the equation, we can find the electrostatic force between the two objects:
$F=(8.99 \cdot 10^9 Nm^2C^{-2}) \frac{(5.0 \cdot 10^{-6} C)(2.0 \cdot 10^{-6}C)}{(0.5 m)^2}=0.36 N$

A train travels 100 km to reach town A in one hour and 15 min. The train stops at station A for 45 minutes. Then it travels 150

myrzilka [38]

Answer: 62.5 km/hour is the average velocity of the train.

Explanation:

Displacement of the train = 100 km + 150 km = 250 km

Total time train took =1 hour 15 min+ 45 min + 2 hours = 240 min = 4 hours

Average velocity= $\frac{Displacement}{time}=\frac{250 km}{4 hour}=62.5 km/h$

62.5 km/hour is the average velocity of the train.
