Mass surveillance

My Ted-Talk I am 5’8”, weigh 130 pounds, and have a BMI of 19.5, the healthy range being from 18.5 to 24.0. My freshman year I was 5’8”, 140 pounds, and had a BMI of 21.3, still within the healthy range. In reality these numbers really tell you nothing about my health practices now, and my health practices then. My health practices today include clean-eating, vegetarianism, running cross country, and frequent gym visits. Just knowing my weight however, does not reveal any of this. I have enough…

Introduction In this lab, we are measuring the ranges R of the ball as the function of the heights, H, that the ball is dropped from. I will use these data to determined the relationship between the height and the range. Procedure We divided this experiment into three parts. In the part one, the object was to observe the scatter in data. To do this, we set up the equipment: the bounce plate is 20 cm above the table ,the drop plate 20 cm above the bounce plate, a piece of carbon paper…

Specify the sources (causes) of friction. The causes of friction in this lab come from three different sources. One is the string sliding over the pulley wheel. Another is the pulley wheel turning on its axle. Also, the string sliding through the hole; all these cause friction in our experiment. Glider on Frictionless Air Track Lab The acceleration of the glider can be calculated by tracking the speed as it passes through the two photogates. On the frictionless air track a glider is placed on…

boiling, measure the mass of your metal object, marking off your answer to one more decimal place than what the scale marks off. Once the water is boiling, drop the metal into the water, leaving it in for about five minutes to allow it to reach the temperature of the water (100.0 °C) Place one Styrofoam cup into the other. This will be your calorimeter. Measure the mass of the calorimeter. Fill about ¾ full with room temperature water, then measure the mass again, determining the mass of the…

the circumference of a soccer ball. The typical radius of a soccer ball is 8.65 inches and the diameter of a typical is 17.3 inches. All of these measurements are important to find the weight of the soccer ball, and the ball’s mass. The equation to find mass is Density=Mass/Volume, to find volume for a sphere the equation is Volume=4/3πr^3. The average weight of a correctly-inflated soccer ball is 420-450 grams, or 0.925942 0.99208 pounds. The weight of the ball is important because it can…

Chapter 4 Questions 1. If the acceleration of an object is zero, are no forces acting on it? Explain. a. No, forces would still be acting on an object if its acceleration is zero. Acceleration is only the change in velocity and in the F=ma equation, the F stands for net force. For example, if a car was traveling at a constant velocity, it would still have forces such as gravity, friction, and normal force acting on it. 2. Only one force acts on an object. Can the object have zero acceleration?…

they make a pass and it is collecting water because it is raining outside and the more water it gets filled up with the more weight and mass/pressure is being put towards the ball think of it as the Toy cart \experiment the more mass it was put on the less it accelerate but with the force it gets from falling down the ramp is like the soccer ball the water is the mass/weight that is being put toward the soccer ball but if you use enough…

dimorphic, and females are considerably smaller than males. The female chacma weighs from 12 to 25 kg (26 to 55 lb), with an average of 15.4 kg (34 lb).[7][8][9][10] It is similar in size to the olive baboon, averaging slightly higher in mean body mass, and of similar weight to the more compact mandrill, the males of which weigh on average about 1 kg (2.2 lb) more than a chacma baboon, the females weigh 3 kg (6.6 lb) less than the female…

This experiment is to be used to determine the era of which the composition and thus the density of the penny changed, and what the other metal besides copper has made up the composition since 1962. First, ten pennies from three different time periods (1995-1999, 2000-2004, 2005-present) were gathered. All ten pennies from a specific time were weighed together on an analytical balance. Then, a fifty mL graduated cylinder was filled with twenty mL of water, which was recorded as the initial…

potential, kinetic, heat, and sound energy. Energy is not completely being destroyed, its just being transferred. We can use Newton's 3 laws to prove this statement. Newton's first law is energy cannot be destroyed nor created, second law which is force = mass * acceleration, and three for every action there is an equal and opposite reaction(will talk more about this my my body paragraph). The potential energy will lower, and kinetic will rise. As it is dropped, the gravitational potential…
