The piece of evidence that suggests that the inner planets were formed from the same rotating cloud of gas and dust is that the planets orbit the sun in the same direction and in the same plane
Smaller planets like Mercury, Venus, Earth, and Mars are considered inner planets. Mercury is thought to be the smallest inner planet, with Earth being the largest. The vastly larger outer planets, such as Jupiter, Saturn, Uranus, and Neptune, are the opposite.
A route that an object or planet in space follows around another body is referred to as an orbit. Moons are satellites that orbit many planets. A man-made satellite is also possible, such as the International Space Station.

Answer:
Increase, increase
Explanation:
For a light bulb, voltage, resistance and current follows the Ohm's law:
where
V is the voltage
R is the resistance
I is the current
In this problem, the voltage is fixed: V=120 V. We can rewrite the equation as
(1)
we see that the current is inversely proportional to the resistance: so, if we decrease the resistance of the filament, the current will increase.
Moreover, the power dissipated by the bulb is
which can be rewritten using (1) as
We see that the power dissipated is inversely proportional to the resistance: therefore, if we decrease the resistance of the filament, the power dissipated will increase.
Answer:
New radius of the charge particle when potential is increased by 3times of initial value
Explanation:
As we know that charge particle is accelerated due to potential difference V then we have
now the speed of the charge particle is given as
now in constant magnetic field which is perpendicular to the motion of charge we have
now we have
now we have
[/tex]
now if we changed the potential to three times of initial value then we have
so we have
Answer:
5 metre.
Explanation:
Wavelength = Velocity / Frequency
= 23,000/ 4,500
= 5 metre.
