Questions in physics

[Homework Help] Will an object with a density of 1.05 g/ml float or sink in water? Explain.

[Homework Help] In an atom, where are the electrons with the least energy most likely located?

[Homework Help] Work equal to 136.0 Joules is expended in moving \(8.5 \times 10^{18}\) electrons between two points in an electric circuit. What potential difference does this establish between the two points? A ball is thrown into the air. At the highest point, the ball has zero velocity and zero acceleration. Is this true or false, and why?

[Homework Help] A student notices that an inflated balloon gets larger when it is warmed by a lamp. Which best describes the mass of the balloon as a result of this change? A. The mass of the balloon increases because the size of the balloon has increased. B. The mass of the balloon increases because the temperature of the balloon has increased. C. The mass of the balloon stays the same because the gas inside the balloon still has the same mass after it warms up. D. The mass of the balloon stays the same because warming decreases the mass enough to cancel out the effect of increasing the size. **Please explain why you chose your answer.**

[Homework Help] The term “radiation” refers to hot materials inside the Earth rising towards Earth’s surface, cooling, and sinking back down. Rewrite the following sentence to clarify the concept and correct the terminology: The term "convection" refers to hot materials inside the Earth rising towards Earth’s surface, cooling, and sinking back down.

[Homework Help] Lighting a match results in light and heat. Since energy was not created by the match, what transformation took place?

[Homework Help] Haloke does 176 J of work lifting himself 0.300 m at a constant speed. What is Haloke's mass?

[Homework Help] Why can velocity and speed be interchanged in the formulas?

[Homework Help] When a star is in the main-sequence stage of its life, it is fusing __________ into __________.

[Homework Help] Describe a situation where you can accelerate even though your speed doesn't change.
