differs from a temporary magnet. 18. A wire that is 0.50m and carrying a current of 8.0A is at a right angle to a uniform magnetic field. The force on the wire is .40N. What is the strength of the magnetic field? B=0.1 T 19. A beam of electrons moves at right angles to a magnetic field of 6.0 x 10⁻² T. The electrons have a velocity of 2.5 x 10⁶ m/s. What is the magnitude of the force on each electron? F=2.4x10-14 N 20. An electric wire inside the wall of a building carries a dc

through a more advanced explanation. Roller coaster rides involve a great deal of physics. The ride often begins with a chain and motor which exerts a force on the train of cars to lift the train to the top of a tall hill. Once the cars are lifted to the top of the hill‚ gravity takes over and the rest of the ride works on energy transformation. There is no motor or engine that takes a train around the track. The law of physics is basically the engine of the train. At the top of the hill‚ the cars possess

AP10005 Physics I Tutorial 7 (Chapters 17‚ 18) 1. (17P11) A flower pot is knocked off a window ledge from a height d = 20.0 m above the sidewalk as shown in the figure below. It falls toward an unsuspecting man of height h =1.75 m who is standing below. Assume the man requires a time interval of Δt = 0.300 s to respond to the warning. How close to the sidewalk can the flower pot fall before it is too late for a warning shouted from the balcony to reach the man in time? 2. (17P15)

Pendulum Problems ACTIVITY 1: Copy and paste the example problem and the steps‚ so that the steps are in the correct order into a new Word document and upload it to Moodle. Example Problem 1: A hypnotist swings her watch from 20.0cm chain in front of a subject’s eyes. What is the period of the swing of the watch. Thus‚ we see that the pendulum used by the hypnotist has a period of 0.898s. | Before we can use this formula‚ however‚ we must ensure all our variables are in the correct units.

The physics of scuba diving Imagine swimming in the underwater world with all the creatures and all the beauty it holds. It is an amazing feeling to swim over coral reefs and see all the sea life up close and personal. So many scuba divers all over the world share a passion to scuba dive. Scuba diving has been a worldwide endeavor for centuries (1). Persian divers were making goggles for diving around 1300. A British engineer invented the air pump in 1771 and in 1772 a Frenchman tried inventing

Year 12 Physics 2014 ER – The Physics of Medicine Extended Response Task [Type the author name] This report will discuss how cerebrovascular disease‚ in particular ischemic stroke‚ can be diagnosed using magnetic resonance imaging scans. It will go through the different MRI sequences and the physics behind them. Evidence from two case studies are presented‚ which use the MRI sequences discussed within this report. Consequently‚ the recent advances in diagnostic techniques and methodologies will

“Cartoon Physics‚ Part 1” Nick Flynn centers “Cartoon Physics‚ Part 1” around childhood innocence. He very strongly urges not only parents‚ but anyone around a young child to not force upon them knowledge they do not need to know. Flynn captures the simple kid mind and harsh reality with tone‚ imagery‚ figurative language‚ and even the form of the overall poem. There is a stark contrast between tones in the passage. In the first few lines the tone is cold; detached. The actual physics of the never-ending

Sakib Khan Electric Eels – Physics The animal that is usually known as electric eel is in fact not really an eel but a freshwater species related more to the carp family or catfish family. These unique freshwater predators got their name from the immense electrical charge that they can easily generate to stun or even kill their preys and dissuade predators. Electric eels can grow extremely large which usually can reach as high as 8 foot long and weigh a great amount of 45lbs. In addition to this
