The layers of rocks, the ancient treasures that are at the bottom of the sea, how old the coral is. But I don't think they determined how old it is, how would the dinosaurs that lived in water swim or any drink water. I don't know if this helps but hopefully it does. Also scientist have made advanced tech that could help with the age determination of the ocean floor.
Answer:
Because the ping pong ball has a lesser mass than a baseball; hence the ping pong ball will accelerate faster than the baseball when a constant force is applied to both
Explanation:
The force applied to an object is a product of its mass and acceleration i.e. F=ma. According to Newton's second law of motion, the relationship between the mass of an object and its acceleration when force is applied to it was described.
In a summary, the second law states that that the acceleration of an object increases with increased force and decreases with increased mass. This means that the more the mass of an object, the greater the force needed to make it accelerate and also the more the mass, the lesser it accelerates.
In this case, a ping pong ball has a lesser mass compared to a baseball, hence, it will accelerate faster than the baseball assuming an equal force was applied. Since the ping pong ball will accelerate faster, it will hit a person faster than the baseball.
Sensory neurons in finger will start a chain reaction that is passed through the neurons from the finger tip all the way through the brain. The brain is then capable of interpreting the reaction and will immediately send response back through motor neurons capable of immediately moving the finger. Depending or the severity, swelling and bleeding may occur around the affected area.
A scientific theory is an explanation of an aspect of the natural world that can be repeatedly tested and verified in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results. Where possible, theories are tested under controlled conditions in an experiment. So it’s the last one.
