Hi there! :)
In the solar system, we can categorize the planets as such:
Inner planets: Mercury, Venus, Earth, Mars
Outer planets: Jupiter, Saturn, Uranus, Neptune
The Inner planets are the only planets that consist of solid rock. They also do not have rings and have impact craters due to their early formation.
In comparison, all of the outer planets are primarily made up of gaseous material and contain rings.
Therefore, the correct choice is B.
Answer:
Though there is no chart on my screen, I can give you the correct information to solve the question without knowing what it looks like. Assuming that this track has slopes and or ramps of any kind, the place where it would have the most potential energy would be at the highest point of this ramp, or and the highest point on the track. This would also mean that it would fall the farthest. The highest kinetic energy would be at the lowest part of the ramp, after its used the slope to its full ability. But this would also be before it hits flat ground, or starts going up another ramp. This would be the point where it would be going its fastest.

Answer:
Night vision goggles capture infrared light given off by heat
Answer:
4186 Joules
Explanation:
The specific heat capacity of a substance is defined as the amount of heat needed to raise the temperature of 1 kg of the substance by 1 Kelvin. In formula,
where
Q is the amiunt of heat needed
m = 1 kg is the mass
is the variation of temperature of the substance
For water, the specific heat capacity is 
. This means that the heat energy required to raise 1 kg of water by 1 K is exactly 4186 J.
Answer:
correct answer is b
Explanation:
The frequency of a wave depends on the properties of medium density and the elasticity properties change the amplitude depends on the energy carried by the wave, that is, the amplitude is proportional to the height of the wave (oscillation).
Consequently the amplitude of independent of the frequency because it depends on different factors.
Therefore when changing the amplitude the wavelength remains constant
the correct answer is b
