Answer:
it right. Its The Iron Nail i just did it and i got correct (:
Explanation:
This claim isn’t true. This claim is trying to say that once force is being applied to Newton’s Cradle then it will forever stay in motion. However, from the excerpt we learn that this isn’t possible. As one of the balls are pushed, it is set into kinetic energy, and then that ball will hit another and send it into kinetic energy as well. However, not all of the kinetic energy is kept through this process, some of the energy is lost and converted into different forms such as sound energy. Therefore, it isn’t possible for Newton’s Cradle to stay in motion forever.
Answer:
0.055 kg
Explanation:
According to the given situation the solution of the mass of the string is shown below:-
Speed of the wave is
Mass of string is
After solving the above equation we will get the result that is
= 0.055 kg
Therefore for calculating the mass of the string we simply applied the above formula.
Answer:
No.
Explanation:
If the so called Dinosaurs died from an asteroid but yet the species of DOGS lived, I'm sure humans can live.
The object has a mass of 15 kilograms. Therefore, it weighs 147 newtons on Earth, where gravitational acceleration is 9.8 meters per second per second. To counteract gravity, the acting force needs to be at least 147 newtons, It has to move 3 meters upward. When multiplying force by distance, the product comes to 441 joules, where joules are the standard unit of work.
