Body mass index

The objectives of this lab where to determine the empirical formula of a hydrated copper (ll) sulfate sample, practice writing detailed observations in the laboratory and practice calculating mass percent composition. Before beginning taking measurements, read through the instructions below and make a neat table in which to record all the numerical data. Using tongs put a clean crucible on the hotplate. Heat the crucible for approximately 5 minutes. Turn off the hotplate. Carefully remove the…

Move the ramp to an angle of zero (horizontal) and draw a free body diagram of the cabinet here: On a horizontal plane, the normal force is _Perpendicular_______ to the weight. The cabinet has a mass of 100kg. It therefore has a normal force of __-100______ N and a friction force (on the horizontal plane) of _2.22N_ μ = 0.30  the ramp and draw a free body diagram of the cabinet in the box here: The force down the plane and normal force are components of __force diagrams__________. Before…

until something stops it or if a person throws a Frisbee in the air it will still spin and fly until it gets caught by someone or something intercepts. His second is acceleration to get acceleration you first must apply force to the object and to the mass of the object impedes that force. And his third law is action and reaction for every action there is an equal and opposite reaction. Newton’s…

Background Gravity/Freefall: Every object on the Earth’s surface is pulled towards the center of the earth by the force of Gravity. Gravity causes all objects in Freefall to accelerate downwards at the same rate, regardless of the object’s mass. On Earth, acceleration due to gravity is constant of 9.81m/s^2. Therefore on Earth when air resistance is not present, all objects fall at the same acceleration of 9.81m/s^2. However, on the planet Vela Rani, the value of acceleration due to gravity is…

direction. The acceleration is also inversely proportional to the net force. Thus, the net force, which is the sum of all the forces acting on an object, is equal to the mass of the object multiplied by its acceleration. In this experiment, a cart with a mass M was placed on a frictionless air track. The cart was attached to a hanging mass (alligator clips), represented by m, by a string through a pulley. The instruments used in the experiment are: a cart, string, track, 5 alligator clips,…

improved by using 2 different eggs, as the data seemed inaccurate when placing a hypotonic egg into a solution of corn syrup made the egg hypertonic, because there wasn’t a proper start weight in the egg when placed in the second solution. The egg gained mass when it was submerged in water because water naturally enters the egg to balance the amount of water inside and outside the egg as much as it possibly…

Purpose: To investigate how acceleration of an object varies with an applied external force and the object’s total mass. Materials: Dynamics cart Track Pulley and clamp Retort stand Mass set Motion sensor Computer interface String Procedure: The apparatus was set up as demonstrated by the teacher. DataStudio software was opened using the Newton’s Second Law Experiment file found in the following location: I:4StudentsOUTRyanGrade 11 PhysicsExperiment FilesNewton’s…

Jack Shumski Professor Verdecia Fire Technology 102 20 November 2017 Physical Principle of a Catapult to The Fire Service A catapult does many different things that relate to different physical principles. The big physical principle of the catapult is it uses Newton's first, second and third law. In fact, also all three of Newton's law can relate a lot to the fire service and how it operates. This essay will relate the physical principle of the catapult, to Newton's laws and how it relates to…

Experiment 37: Friction Anne Smolinski as910513@ohio.edu Wednesday 11:50-1:40 TA: Sanjoy Sarkar November 11, 2017 Experiment 37: Technical Report ABSTRACT In experiment 37, the friction force is being explained and tested by using a block that is being pulled across a wooden base. Out of the four different types of friction, two will be tested during this experiment: (i) static and (ii) kinetic. Static friction can be defined as the force that resists motion of an object to a surface so…

1.1. Mechanical properties of CP/CNF and CP/CNF/ZIF-67 1.1.1. Stress–strain curves The stress–strain curves and the effects of CNF dosage on the tensile strength, elastic modulus, and elongation at break of CP/CNF and CP/CNF/ZIF-67 are shown in Fig. 3 and Tables S1–S4. As shown in Fig. 3(A) and Table S1, the tensile strength, elastic modulus, and elongation at break of neat CP is 7.37 MPa, 996 MPa, and 3.07%, respectively. After coating and crosslinking with CNFs, the mechanical properties of…
