Explanation:
Answer:
0.230 s
Explanation:
The period is the length of time from one peak to the next. If it takes the oscillator 0.115 s to go from the lowest point to the highest point, then it takes another 0.115 s to return to the lowest point. So the period is 0.115 + 0.115 = 0.230 seconds.
A block and tackle or only tackle is a system of two or more pulleys with a rope or cable threaded between them, usually used to lift heavy loads.
Answer:
Kinetic energy is the energy obtained from movement while potential energy is the energy in something when it is at a height or has been manipulated in some way; it has work done to it.
Explanation:
Kinetic energy is, like I said, energy gained through movement or action. When an object stops moving, it converts into a different type of energy. Energy cannot be destroyed or created. An object with potential energy has a reference. A reference determines how high it is. The higher and heavier an object is, the more potential energy it has.
Hope this helps!
Answer:
All object changes are compared with a <em>reference</em> , which is an object that appears to stay in place.
Explanation:
In scientific experiments, the changes in the experimental object are observed by comparing the changes with a reference object. In the reference object, no changes are made and conditions are kept normal in it. For example, if we want to measure the distance of two cars from a point, the point will be the reference point from which the distance shall be measured. Hence, all changes are made by comparison from a reference object or point.
