QUESTION 4 DOK 4 In the morning, your cell phone has a full charge. However, by the end of the day, your battery dies. Does this violate the conservation of energy? Explain why or why not. ​

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change? work power gravitational energy chemical energy

Explain why you think this diagram shows what happened to the carbon in the biodome.

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
