If it is surrounded by magnets of the same polarity, we are talking perfect calculations, will the stationary magnet spin to "stay away from the surrounding magnets" or will it just find an area of least resistance and stop....

Report says scientists say we must return to the moon. Why?

I'm not opposed to space exploration and was a fan of Gerard O'Neill's idea of cities in space. I know that space exploration has given tremendous strength to technological development that have radically improved our lives. A late-uncle who had a machine shop that worked with the Apollo program said the biggest technology improvements in machining at that time came because of auto racing and NASA. Electronics, meanwhile, have soared on technology advances begun for space. Even medicine has had quantum-leap moments in part spurred by NASA needing to understand the humans they send up.

But why MUST we return to the moon?

Calculate the percentage yield of aspirin from this experiment if you obtained 2.6 g of aspirin when starting with 2.5 g of salicylic acid. The percentage yield is the amount of product you obtained as a percentage of the amount of product that would be produced if the reaction produced 100%, based on stoichiometry.Percentage yield of aspirin (to at least 1 decimal place)

Sally has a box of donuts.
She gives 1/2 of the total to her mom and another 1/2.
She gives 1/2 of what's left to her aunt and another 1/2.
She gives 1/2 of what's left to her sister and another 1/2.
She has 1/4 of a dozen left over.

How many donuts did she start with and how many did each person get?

Please show me the algebra equation you used to get this answer.

Thank you so much
