He placed the his temperature scale at o degree for the boiling point, and ent downward and placed the freezing point at 100 degrees 10. What did the physicist Amonton contribute to the understanding of hot and cold? Amonton was doing heating, and cooling experiments. He saw that when he cooled the object that when the temp dropped so did the pressure. So he thought what would happen if you kept pushing the pressure back.
B. How does the change in temperature affect the volume of the container? Get the Gizmo ready: Activity A: Boyle’s law Set the temperature (T) to 300 K. Check that the mass (m) is set to 0 kg. Question: How does pressure affect the volume of a gas? 1.
We improve the egg holder to a diamond shape container, and the new egg holder perfectly protect the egg from any directions. After the egg survive, we calculate the impulse, acceleration, velocity and net force. We find the time is independent variable, and the net force is dependent variable. The relationship between them is shorter time means lager
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.
Activity 4: If you put a pile of tin plates on the top of the generator’s globe, they will fly off one at a time. Since each of them will be picking up some of the excess charges the plates repel each other and they will fly off one at a time. Activity 5: A piece of tinsel or Christmas tree icicles will first be attracted to the globe by induction, just like when you stick a charged balloon to the wall, and then repel away from the generator after it picks up some excess charge. Activity 6: If you start with your hands on the globe and then turn the generator on you won’t get a shock, because the charge doesn’t get a chance to build up. The charge will continually leak into you and then through you to the ground.
[pic] As he tried his approach with inclined planes of different angles, he discovered that the acceleration changed. He asserted that as the angle of the inclined plane approached 90°, the acceleration approached our current value of g. Thus, he related acceleration due to gravity with the sin of the angle of the plane. a = g sin θ More importantly, he found that all bodies, regardless of weight, fall with the same uniform acceleration. The Experiment: [pic] Determining g on an Incline Purpose To use a motion detector to obtain the speed and acceleration of a cart rolling down an incline. To determine the free-fall acceleration g from a graph of acceleration vs. sine of track angle.
HSC Syllabus Summary - Space 1. The Earth has a gravitational field that exerts a force on objects both on it and around it Students learn to: * Define weight as the force on an object due to a gravitational field. * Weight is the force on an object due to a gravitational field. This force is created by the gravitational field that surrounds the Earth: F=mg. This field, given by g=GMr2, (where g is the acceleration due to gravity or the gravitational field strength, G is he universal gravitational constant, M is the mass and r is the radius of the planet) acts on objects both on Earth and around it.
In addition, entering a black hole would not only take thousands of years to occur, according to “Spaghetti theory” the gravity would be so intense as you neared the center of the black hole, your body would be stretched out into a thin strip of organic matter. Not to mention that this is all assuming that black holes are connected to other black holes in some separate universe and at a different time. Speaking of which, since time is relative, Spock going into the black hole a few seconds after The Narada, and coming out after it has been 25 years is quite plausible. So both the timeframe and how this scene was portrayed have little scientific background and is most likely
In this experiment, frictional forces heat an aluminum calorimeter. The work of friction should be equal to the heat energy gained by the calorimeter. The heat energy gain can be easily found by measuring the change in temperature (ΔT) and by knowing the mass of the aluminum calorimeter (Mc). The heat energy gain Q is given by Equation (2). Q = Mc Cc ΔT (2) Where Cc = 0.215 cal/(g °C) A nylon cord is wound five times around the aluminum calorimeter.
Uniform Acceleration Francesco Saccaggi Jordan Biovin Christopher Sigmon Physics 183-B 9/12/2011 Abstract This formal lab report defines what uniform acceleration is and how to calculate uniform acceleration of a ball rolling down a ramp and an object falling down. The two experiments will be performed by rolling a pool ball down a steel ramp and calculating where the ball will be at each second that passes by. The second experiment is finding the objects position when it falls down at a given time. The photogate can be used to calculate the position of the object as it falls down. Once the results are found you can calculate the percent error of the uncertainty values.
