Because after each impact it loses a fraction of its original energy, because it gets transfered to the floor. this is the reason that a perpetual motion machine is impossible. you cannot have infinite energy, because to perform a task, energy must be spent. hope i helped :3
Answer:
U can walk to the bathroom
Explanation:
We are given that a 500 kg object is hanging from a spring. To determine the amount the spring is stretched we will use Hook's law, which states the following:

Where:

Since the object is hanging the only force acting on the spring is the weight of the object. The weight of the object is:

Where:

Plugging in the values we get:

Solving the operations:

Now we solve for "x" from Hook's law by dividing both sides by "k":

Now we plug in the known values:

Solving the operations:

Therefore, the spring is stretched by 5.4 meters.
Answer:
The distance of the object from the concave mirror determines if it is a virtual or real image
Explanation:
Concave mirrors form both real and virtual images. When the concave mirror is placed very close to the object, a virtual and magnified image is obtained and if we increase the distance between the object and the mirror, the size of the image reduces and real images are formed.
