Different colors after reflection appear due to the different wavelengths of light. Therefore, option C is correct.
The wavelength of the light can be defined as the distance between the two points in phase w.r.t. each other such as two crests or troughs on a wave. The frequency of the light is the number of oscillations of a wave in one second and has S.I. units of per second or hertz.
The expression between frequency (ν), wavelength (λ), and speed of light (c) is:
c = νλ
A wave moving at a fixed wave speed has a wavelength that is inversely proportional to the frequency therefore, the waves with higher frequencies have shorter wavelengths, while lower frequencies have higher wavelengths.
The speed depends upon the medium as it propagates. In particular, the speed of light in a particular medium is less than in a vacuum, therefore the same frequency will have a shorter wavelength.
When the light is reflected the colors are formed as due to different wavelengths.

2. Due to the Earth warming, it emits infrared light back toward space, but carbon dioxide absorbs it and causes the atmosphere to heat up. Carbon dioxide acts like a blanket.
3. The Earth becomes hotter than before
I hoped that this has helped some way, if you have an further questions feel free to shoot me a question or message. Good luck :)
Answer:
If the amount of energy from the sun and the amount of greenhouse gases such as methane, carbon dioxide in the atmosphere remain the same, the average temperature on Earth will also be constant. But in the current scenario the amount of greenhouse gases has exceed the amount the earth receives the sunlight due to burning of fossil fuels and others. The greenhouse gases are made of three or more atoms. This structures allows the gases to trap heat from the atmosphere and re-emit it towards a surface which further warms the earth climate. This effect is called as greenhouse effect.
A. 7.0 newtons
B. 70 newtons
C. 700 newtons
d. 7000 newtons
Weight = (mass) x (gravity)
Weight = (7.0 kg) x (gravity)
On Earth, where (gravity) is roughly 10 N/kg . . .
Weight = (7.0 kg) x (roughly 10 N/kg)
Weight = roughly 70 Newtons
That's B on Earth.
It would be some other number on other bodies.
Calculate the current in the 200.-ohm resistor.
Answer:
current in 200ohm resistor = 0.05A
Explanation:
for current in 200 ohm resistor,
let 'I2' and 'R2' be current and resistance in 200 ohm resistor,
potential difference remains same thorughout the circuit because they are connected in parallel,
we have,
V=10V
R2=200 ohm
I2=?
then by ohm's law,
V=I2*R2
10=I2*200
I2=0.05A
The power dissipated by the 100-ohm resistor is 400 watts. The current in the 200-ohm resistor is 0.05 Amps.
To determine the power dissipated by the 100-ohm resistor, we can use the formula P = I^2 * R, where P is the power, I is the current, and R is the resistance. Since the current is the same throughout a parallel circuit, the current flowing through the 100-ohm resistor is the same as the total current in the circuit. Using the formula P = I^2 * R, we can calculate the power dissipated by the 100-ohm resistor as P = (2.00 A)^2 * 100 ohms = 400 watts.
To calculate the current in the 200-ohm resistor, we can use Ohm's Law, which states that the current (I) is equal to the voltage (V) divided by the resistance (R). In this case, the voltage supplied by the battery is 10.0 volts. Using Ohm's Law, we can calculate the current in the 200-ohm resistor as I = V / R = 10.0 V / 200 ohms = 0.05 Amps.
