The answer is "C" because the equator is closest to the sun, because the sun's rays hits the earth surface at the higher angel at the equator and also the sun is directly overhead the equator.
Answer:
Shorter waves vibrate at higher frequencies and have higher energies. Red light has a frequency around 430 terahertz, while blue's frequency is closer to 750 terahertz. Red photons of light carry about 1.8 electron volts (eV) of energy, while each blue photon transmits about 3.1 eV.

Explanation:
Acceleration: It refers to the change in velocity/speed of an object with respect to time. When the speed increases with time we call it acceleration and when its decreases it is called as deceleration. Let us analyze each instance individually:
1. When roller coaster starts to roll down the track its speed will increase with time. That means it is accelerating.
2. When the ball reaches at the peak of its trajectory, it comes to a stop for a fraction of a second that means it decelerates.
3. Since the velocity remains constant there is no acceleration.
4. Since the speed is no changing with time, there is no acceleration.
5. Since the moving plane comes to a stop, it is a case of deceleration.
6. Since the truck is moving at a constant speed so the acceleration is zero.
