Make sure the launch range is clear of any obstructions. 2. Using the Plumb Bob and sticky note, mark the floor underneath the launch point. Measure the height of the launch point using the metric ruler once per person and take an average. 3.
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.
You can us+e the weight on each pully to calculate the magnitude and the direction of the component vectors at 90 and 0 degrees. For part c you need to find the components of triangles a, b, and c as labeled on the front bottom of my lab. You then need to find the sum all the x component and y component vectors. Then from the sum of the components you can use the Pythagorean theorem to find the resultant vector R. Data: part a experimental ax= 875g*m/s^2 ay = 980g*m/s^2 the theoretical values for ax and were
Then measure the Beaker by itself and calculate the weight of the slug by difference. Then record all of the values in the table below. Then repeat this process using a second copper slug and a second 100ml Beaker and a second Centigram Balance. Next, use an electronic balance to calculate all of the same weights as mentioned before. Do this twice to get a more accurate measurement.
To measure the circumference of the disk, make a mark on the disk and place the disk on the meter stick with the mark coinciding with a meter stick reading. Roll the disk for one revolution along the meter stick to obtain the circumference. Measure and record this value. Do this for each disk. Iv .
Figure 2 shows a circuit with a resistor R = 1.0 × 103 Ω, and a battery with potential difference of VB = 5.0V . (a) Solve the circuit in Figure 2. That is, find all unknown currents, voltages, and resistances. (b) What is the direction of the current? Note: I want the direction of the conventional current.
We did the calculation after we finished the measurement and adjustment. The find day we make the graph of the contraption, and then do the final drop test. Problem of Statement: To design a device that will protect 1 large Grade AA raw egg from breaking when it is dropped from second floor. The device should have a light weight short egg removal time, and the most accurate drop to the drop zone target. Diagram of the Contraption: Prototype: The contraption after adjustments:
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)
In your right hand hold the pipette with Na2S203 and squeeze the Na2S203 into well #1 and start timing with your stopwatch. 16. Observe well #1 while a reaction occurs. Stop your watch when you can no longer see the X sign through the bottom of the well. Record the exact time in seconds under the Trial 1 column in the Data Table
Suggest two reasons for this change. Task 2 Press back but not clear and change the number of chips to 10 but leave the acid concentration at 1.0 mol/dm3 . Click start and take readings approximately every 3 seconds (by clicking the take readings button) until the mass reaches 0.0 g. Stop the reaction immediately. Plot these results on the same grid as the results of your first experiment. How does the rate of reaction in Task 2 compare with the rate in Task 1?
