CER: You launch a cannonball at two different angles. One at 30 degrees and the other at 75 degrees. You control (keep the same) as many variables as you can.
To do this you make sure the initial velocity and initial position are the same for
both launches. Which launch will travel higher. Why? Explain in
Claim/Evidence/Reasoning format. Make a claim, list your evidence, and explain
your reasoning.

The answer is a i think

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current

What is on your multiple choice anwers

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.
