3. Set the launcher to launch horizontally. 4. Load the Launcher to the Medium range at the first click. Take 2 test runs and then tape a piece of white paper on the floor and put the carbon paper on top of it.
Use your line graph from Part II to interpolate, or estimate, atomic radius of Tin (Sn). (1 point) Answer: By using the given line to interpolate the atomic radius of tin, it can be found that its radius is around 149pm. 5. Tin’s actual atomic radius is 140 pm. . Use the math equation below to determine the percent error of your estimated value. (2 points) Percent error = × 100 This equation means that you subtract to find the difference between the actual value (given in this problem) and the experimental value (estimated from the graph).

Physics 1408 Section E1 Standing Waves in a Vibrating Wire Callie K Partner: Miguel E Date Performed: March 20, 2012 TA: Raziyeh Y Abstract This lab had two purposes. The first was to determine the relationship between the length of a stretched wire and the frequencies at which resonance occurs. The second was to study the relationship between the frequency of vibration and the tension and linear mass density of the wire. In the first part we found the resonance, frequency and wavelength of a wire and used this data to calculate the speed of the traveling waves. For first harmonic, our wavelength was 1.200 m, found by the formula λ=2L/n.
Planck's constant: the constant relating the change in energy for a system to the frequency of the electromagnatic radiation absorbed or emitted, equal to 6.626 X 10^-34 J 5. Quantization: the concept that energy can occur only in discrete units called quanta 6. Photon: a quantum of electromagnetic radiation 7. Photoelectric effect: ejection of electrons from a substance by incident electromagnetic radiation, especially by visible light 8. E=mc^2: Einstein's equation proposing that energy has mass; E is energy, m is mass, and c is the speed of light 9.
It told us the only way to change the motion of an object it to apply a force. en.wikipedia.org/wiki/Isaac_Newton 6. How much force are you exerting when you lift a 50-pound dumbbell? What units will you use to describe this force? F= Force M=Mass g=Earth gravity 50 pounds= 22.67 KG F=22.67 X 9.8 N =222.16 N You are exerting 222.16 N(Newton)
PK-S Lab 03 – Lab Report Name: ____________________ Section: ___________________ EXPERIMENT 3: Trigonometric Measurements Procedures: 1. Experimental measurement of the angles and sides of a right triangle: A. Create a triangle by taping a string against a wall and taping the bottom of the string to the floor or a table set against the wall. Make sure that the wall is perpendicular to the floor or table by measuring angle C, which should be 90o. B.
Connor Schroeder Vector experiment Objectives. : The objective is to determine the components of a single vector and to find the sum of two or more vectors using the force table. Apparatus : A force table, mass hanger and a slotted mass set are required to complete this experiment. Experimental procedure: On the table, you set a 200 gram mass at 30 degrees. Then you place another 200 gram mass on the 210 degree mark.
The distance between the forces is given by the Coulombs law through the use of the formula F=kq1q2/r2.0.1newtons = 8.99*109*3.2*10-6*7.7*10-7/r2 R= 555.78 Answer to question 3 • Potential difference between the two plates is equal to velocity which is equal to 6.0*106m/s • Force = mass *acceleration = 1.4*10-13*6.0*106 = -8254 nektons The speed of the particles are computed by the formula V=ED. This is equal to 8.5*10-6*0.15. This is equal to 84.1 Answer to question 4 Voltage = current *resistance. This implies that in this case while V is 5.0 and resistance is 1.0*103, current will be equal to 5/1.0*103, = 500 amps B the direction of the conventional current provides the electric charge movement from the positive side of the battery to its negative side as in indicated in the diagram below Answer to question 5 • This section focuses on the equivalent resistance of a circuit. The equivalent resistance will be equal to (5.0*102+1.00*103)2.
