The stretched spring stores elastic potential energy.
The elastic potential energy stored in a spring can be found by using the equation:
Elastic potential energy = 0.5 spring constant × (extension)²
A particular spring has a spring constant of 25 N/m.
Calculate the energy stored when the spring is extended by 15 mm.
ive your answer in standard form, to 3 significant figures.
Energy stored = J

When a neutral charge, comes into contact with a positive charge they repel each other nothing happens the neutral charge becomes negative they attract each other

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.

The combining of light nuclei is called blank. blank as in not actually blank. you know what im tryin to say.
