Terminal speed is the maximum speed that a falling object can reach and is based on aerodynamic resistance. In a vacuum, an object falling toward a planet as a result of gravity will continue to accelerate until it hits the ground.
However, if the object is falling through an atmosphere, such as on earth, then it will accelerate up to the point that the aerodynamic resistance cancels the downward force due to gravity, and it travels at a constant maximum speed, called the terminal velocity. At this point, resistance is equal to acceleration due to gravity. At terminal velocity, the skydiver's acceleration is zero.
The cathode and anode are hooked up to an electrical circuit The chemical reactions in the battery causes a build up of electrons at the anode. This results in an electrical difference between the anode and the cathode. Hope this helps :)
Answer:
Explanation:
Total internal reflections is a phenomenon where incident light rays when travelling from a denser medium or from a medium with higher refractive index to less dense medium or a medium with lesser refractive index ( The indices of refraction have the relation n₁ > n₂, where n₁ is the refractive index of the first medium and n₂ is the refractive index of medium 2) leads to the light ray being reflected back into the first medium instead of undergoing refraction. Usually, this occurs when the incident light rays angle to the normal is greater than a certain critical angle which is the angle when the refracted ray angle in the second medium is 90°
Answer:
B
Explanation:
graph b shows a steady pace of movement for 20 minutes and then shows a plateau in the distance, showing that while time keeps moving (obviously), the distance doesn't change. then after 5 minutes, the student gets up and starts running again. hope this helped!
Answer:
Option c that it means cm/year.
Explanation:
Nm means nanometer, 1x10^9m
Km/s^2 is acceleration
h.. it may be height
