In an investigation on accuracy and precision, Myriah measures the mass of a 10.00 g piece of metal several times. Her measurements are 9.98 g, 10.02 g, 10.01 g, and 9.99 g. Which statement best describes her results? They are both precise and accurate. They are neither accurate nor precise. They are precise but not accurate. They are accurate but not precise.

The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.0 × 10-6 c/m2. (a) what is the magnitude of the electric field within the cell membrane? (b) find the magnitude of the electric force that would be exerted on a potassium ion (k+; charge = +e) placed inside the membrane.

How many neutrons does plutonium -196 with an atomic number of 78.

As seen in a us weather map, the h (or high) and l (or low) symbols indicate regions where surface air pressures are high or low, respectively, compared to surrounding areas. an h is plotted where the air pressure is highest and an l is plotted where the air pressure is lowest. proceeding outward and away from the center of a high pressure system, the air pressure "
