PH 110 Lab #7 Applying Kepler’s Second and Third Laws In this lab we examined the elliptical nature of plametary orbits. In the first part we learned the Law of Equal Areas‚ a law concerning the speed at which planets travel; a line connecting a planet to the sun will sweep out equal areas in equal times; "Kepler’s second law means that a planet’s orbital speed changes with its distance from the sun" The procedure that we follow the orbit of Mar for the year 2004 and 2005

Growth Hormone(GH) – Stimulates an increase in size and rate of division of body cells; enhances movement of amino acids through membranes; promotes growth of long bones. Prolactin (PRL) – Sustains milk production after birth; amplifies effect of LH in males. Thyroid-stimulating Hormone (TSH) – Controls secretion of hormones from the thyroid gland.

Explain the meaning of law and morality. Discuss whether the law does and should seek to uphold moral principles. (30 marks + 5 marks for AO3). Laws and morals are quite similar in some ways but they also have their differences. Law is best described as rules made by authority. John Austin defined law as a command from a sovereign power‚ law needs to be obeyed and is enforced through sanctions. Morality on the other hand is values and principles as opposed to rules. Phil Harris defines a society’s

devastating consequences if no one on the freeway calls for help. It seems as if the more people the more likely that at least one person will call for help‚ but actually the more people present in the situation the more likely each individual will feel less responsible to be involved. In this case‚ the accident is located in a freeway were there are usually many people present; therefore‚ it would take longer for a person to decide to call for help and the longer span of time taken can lead worse injuries

California. Historically‚ “the first Borax specimens came from several dry lake deposits in Tibet” (The Mineral Borax). This experiment was conducted to determine the standard entropy and enthalpy of the dissolving reaction of borax in water. The thermodynamic properties of the reaction helped to determine the change in heat and spontaneity within the system. Entropy is said to be the tendency for the universe to move towards disorder. If the value of entropy is positive‚ then the amount of disorder

was primarily about Newton’s second law of motion. Newton’s second law of motion states that a net force is required for a body to have acceleration. If a net force is applied on an object‚ then the object will accelerate with respect to the direction of the said force. The body’s acceleration is directly proportional to the net force and inversely proportional to its mass. The experiment conducted was used to verify the relationships specified in Newton’s second law of motion. There were 3 trials

Implementation My aim for this experiment was to find the effect of temperature on the membrane permeability of beetroot. Since I was unfamiliar with this experiment‚ I first conducted a preliminary test. I considered my preliminary test as my trial for this experiment. My Hypothesis for this experiment was to found out the amount of pigment loss of beetroot when exposed to varying temperatures. Betalain pigment found in beetroot My method for this experiment is:- * Use a cork borer to cut about

Factors Affecting Diffusion How does temperature affect diffusion? What is Diffusion? Definition 1: Diffusion is a process where by molecules move from an area of high concentration area to an area of low concentration. Definition 2: Diffusion is an evidence for moving particles. The spreading out of a gas is called diffusion and it takes place in haphazard and random way. Gases diffuse because the particles collide with other particles and bounce of in all directions. For example when

Part A: Diffusion on a liquid in a liquid. I did an experiment with three different glasses of tap water from the faucet. All three cups measured the same which happened to be 13 cm from the top of the cup to the bottom of the cup. I let the water settle‚ and sit for about an hour so the temperature was the same for all three cups. I then placed one drop of food coloring into the first glass and waited for the coloring to reach the bottom. I calculated 93 seconds. I then went to the second glass and
