The panel that converts light energy into electrical energy is called a Photovoltaic panel. Light energy is not only used industrially and privately, but some of our vehicles run on part solar electric or entirely on solar electric. The light energy is collected through a panel on the vehicle, which is transferred to electrical energy that hits the motor; the motor then converts the electrical energy into mechanical energy, which turns the drive shaft that turns the wheels (kinetic energy). Not all energy transfer is perfect, there will always be a loss of energy in any system. The loss of energy will come from the electrons passing through any wires, released as heat energy.
INT1 – Task Two Author Note Section A Problem Statement: This experiment is designed to determine the relative resistance of copper wire as temperature changes in order to gauge the effect, if any, that global warming will have on the cost of the delivery of electricity Relevance: Global warming is expected to have a major effect on the ecosystems of the world. Could global warming also affect the efficiency of the delivery of electrical energy and, if so, what is the magnitude of even a small increase in global temperatures? A1. Literature review: In the article on Temperature and Conductivity (Khounsary, 2005): The researcher comments on if temperature would affect the amount of current traveling through a wire. Dr Khounsary explains an experiment using a fixed voltage and varying the temperature of the wire using a torch.

This could be a problem if an eruption was to take place at the Yucca Mountain or close by. An eruption could cause damage to the facility or in the worst case magma flowing through the facility which could damage canisters holding radioactive
Your heart is now working harder to try and pump blood in your body. Hypertension or high blood pressure is normally caused by smoking, being overweight, and not enough physical activity, the intake of the amount of salt you eat, stress, old age, genetics, and also family history. Some symptoms of hypertension/high blood pressure may be severe headaches, confusion, blurred vision,
He claimed that the brain itself was the most important organ for secretion of this electric fluid, and the nerves were responsible for conducting this fluid to muscles and tissues. * The brain and the nerves do generate electric impulses that cause muscles to contract under a physiological state (that is, when the animal is alive). However, these electric impulses are much smaller than ones produced by the contact of two metals and are not present when an animal is killed. Alessandro Volta was a physics professor who made many contributions to the knowledge of electricity. * He invented the electrophorus, a device used to generate static electricity.
The stronger the magnet the greater the field. The static magnetic field can have mechanical effects on the pacemaker. It has been known to effect certain parts of the pacemaker allowing it to revert to different intervals of pacing. It also has the ability to reprogram or reset the device all together. The static magnetic field exerts a magnetic force that can dislodge the pacemaker leads.
I would begin by explaining that blood pressure is the force that your blood exerts on your arteries. If you have high blood pressure it means that your blood is exerting too much force on your arteries and is making your heart’s job even harder. Your heart is a powerful and efficient muscle, but if made to work to hard for too long, it can enlarge and wear out or even fail. This can also cause a heart attack, stroke, even an early death. When you take your blood pressure, you will see two numbers referred to as your systolic and diastolic blood pressure.
Provide a brief explanation based on how the heart functions. Overtime when the fatty residues start building up on the arterial wall or this is called hardening of the arteries, this leaves little movement for the blood to flow through the arteries and to the heart. This blood is important because it contains oxygen and nutrients that are to go to the body’s tissues. If atherosclerosis begins in a coronary artery, blood is unable to flow correctly or not at all to the heart. This can cause the heart to stop pumping which then a person will endure a heart attack.
Also as we get older our bodies weaken, including our chest making vital infections much harder to fight. Nervous system e.g. motor neurone
