On comparing this equation with standard equation of ellipse with centre (h,k) which is given by x-h2a2+y-k2b2=1 , we have , h = 3 and k = -5. Therefore, coordinates of centre of ellipse = (3, -5). b) Given equation of ellipse. On comparing this equation with standard equation of ellipse with major axis 2a and minor axis 2b which is given by x-h2a2+y-k2b2=1 , we have, a2=64=>a=8 And b2=100=>b=10 Therefore, length of major axis = 2a = 2*8 = 16. And length of minor axis = 2b = 2*10 = 20. c) From part a) and b), we have a = 8 and b = 10 and h=3,k=-5 So, c2=b2-a2=102-82=100-64=36 =>c=sqrt36= 6.
For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account. 2. Inertia - A property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force. 3. Potential Energy - Is the energy stored in an object due to its position in a force field or in a system due to its configuration.

The following equation represents this relationship where k denotes the spring constant or stiffness of the spring, F=-kx Since x symbolizes the displacement or change in the length of the spring the above equation can now be surmised in the following manner, F=mg=-k∆l This new form makes it evident that a linear proportion exists between the plot of F as function of changing in length, ∆, thus confirming the spring does in fact obey Hooke’s Law. This enabled the group to determine the spring constant k. B. Derivation of Equations Definitions To gain a better understanding of the terms used here
Friction Objectives: To provide an understanding of the concept of friction. To calculate the coefficient of friction of an object by two methods. Materials: Ramp board: 3 - 4 feet long, 10 cm wide Can of soft drink or item of similar weight Friction block set-PK Protractor Scale-Spring-500-g Tape measure, 3-m Lab notes: Using the wooden block provided in LabPaq, a long board, a can of beans and the 500-g spring scale I will try and determine the force of kinetic friction, N, and the force of static friction, N while pulling the block at a constant speed. I will convert kg-mass to Newtons by multiplying the kg-weight by 9.8 m/s2, i.e., 100 g = 0.1 kg = 0.1 x 9.8 = .98 N.

Abstract Sliding filament theory of muscle contraction suggests existence of an optimal muscle length associated with maximum stimuli-generated tension. This hypothesis is tested in vitro by measuring muscle tensile response to fixed voltage stimulations under length alterations of the gastrocnemius of Xenopus laevis. Muscle length is mechanically varied by shrinking or extending and an attached force transducer records the tension generated by the fixed stimuli. Our results indicate greatest tensile response of about 3.2 N when muscle length is 30 mm. The response diminishes as deviations from this optimal length increases.
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.
Authoritarian script to reduce anxiety Now just close your eyes And move yourself in the most comfortable position you can Throughout this experience you will always be in control........ You will always be aware........ The state that you will achieve is a completely natural state, that will assist you to make the changes that you have sensibly come here today to achieve........ Start by concentrating on your breathing...... And my voice...... The outside noises will start to become irrelevant...... As you use the powerful ability of your mind to concentrate on your breathing......... And my voice will just be helping you to reach this beneficial state for accomplishing your goals...... You will soon start to notice that: * each breath in* takes the same time as *each breath out* Repeat each breath in takes as much time as each breath out...... The next task is to relax your body Your muscles from top to bottom And we will just concentrate on this now....... Still concentrating on your breathing and my voice...............
One must be free from limitations on his/herself and have a free spirit. In Chapter I of Self Reliance, Emerson talks about the idea that when he is standing on flat carefree ground he is uplifted into blithe, carefree air, and no longer has any limits on himself. In this carefree state Emerson “feel[s] that nothing can befall [himself] in life, -- no disgrace, no calamity, (leaving me my eyes,) which nature cannot repair. Standing on the bare ground, -- my head bathed by the blithe air, and uplifted into infinite space, -- all mean egotism vanishes. I become a transparent eyeball; I am nothing; I see all; the currents of the Universal Being circulate through me; I am part or particle of God” (Nature).
