Six data tables (a, b, c, d, e, f) are shown below.
for each table, decide which of two methods (table only or equation, graph, or table) can be used to represent the data.
for the purposes of this question, assume that we only know and can use two graph forms / equations:
x= c t + d (straight line graph) and x = b t2+ c t + d (quadratic curve graph).

Spend time observing or thinking about events that involve matter and energy. which events can you explain? which events can’t you explain?

Which statements describe the movement of ocean currents around the globe? check all that apply. strong winds force warm water to sink to the ocean floor. the coriolis effect causes warm and cold water to mix. cool dense water sinks to the ocean floor. warm water replaces cool surface water. wind blowing parallel to the shore causes upwelling of cool water.

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
