Scientists use different types of microscopes to observe objects that are not visible to the naked eye. a scientist is reviewing various samples of pond water to determine what species of microorganisms live in the pond. the scientist wishes to make drawings of the structure of each microorganism and study each one's method of movement. which of the following microscopes would be best for the scientist to use?

What is the weight of a 8-kg substance in n, kn, kg·m/s2, kgf, lbm·ft/s2, and lbf?

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
