Ohm's law defines the relationship between the voltage, current<span>, and </span>resistance<span> in an electric </span>circuit<span>: i = v/r. The </span>current<span> is directly proportional to the voltage and inversely proportional to the </span>resistance<span>.</span>
B. The neck is the most dangerous part of the rip current because the water’s speed increases and swimmers can be pushed farther into the ocean.
A scale and a ruler. The scale to measure the mass, and a ruler to measure the volume.
