Calculate the electrostatic force of repulsion for two protons separated by 93.0 pm. The charge of a proton is q = 1.6 x 10-1⁹ C. Express your answer to two significant figures and include the appropriate units. Fel = μA 2.7.10 6 Submit N Previous Answers Request Answer ? X Incorrect; Try Again; 5 attempts remaining Use the equation Fel = K(Q₁ Q₂/d²) to find the electrostatic force between the two particles. Q₁ and Q2 are the charges on the particles (charge of a proton here), and d is the distance of separation. The constant is given in the introduction and has the units Nm²/C². This means that the distance must be converted from picometers to meters using the relation 1 pm = 1 × 10¯ m. -12
Normal body temperature is 98.4°F. Use your Celsius temperature from the above question (81) to calculate this temperature in Kelvin. To determine the conversion factors (if you can’t remember them), use the following: Freezing point of water = 0 oC = 273.15 K. Boiling point of water = 100 oC = 373.15 K. Use the correct number of significant figures in your answers.
One student calibrated a 50-mL burette by using the mass of water delivered. The student used an analytical balance which was previously calibratedby STEEL (density = 7.8 g/mL). During calibration, the temperature of water was found to be 19.0oC. The density of water at this temperature is0.9984 g/mL. The results of the calibration by the student is shown in the table below: Apparent burette reading, mL A-10.05 ml, B- 20.04ml, C- 30.08ml, D- 40.07 ml, E- 49.98ml Weight H2O delivered, g A -10.03g, B- 20.09g, C- 30.05g, D- 40.02g, E- 49.83g
