Calculate A dust particle having a charge of -12.6 µC and mass m = 1.68 pg, is observed to move with a velocity of ν = 1.36×104 m/s in a region of a uniform magnetic field (within the dotted square in the diagram). It travels counterclockwise on a circular path of 9.28-cm diameter. The motion is without friction in the horizontal plane- you may consider it to be the plane of the page/screen-. What are the magnitude and direction (into or out of the page) of the magnetic field in this region?
1 A very long line of charge has a linear charge density of 12.5 µC/m. A point charge with a charge of 63.4 µC is placed 0.720 m away from the line of charge. In the space between the line and charge, there is a point where the electric field is zero. How far away […]

Based on what you have learned and what you know about the changes occurring in society, politics, the economy and technology, what will it take for Extension to still exists 20 years from now.
The social, political, economic and technological environments across the the country have certainly changed since Extensuon began in 1914. Some say in 20 years extension will be obsolete. Others say Extension can remain viable if it makes some major changes. Based on what you have learned and what you know about the changes occurring in […]
Your mug contains 300 ml of coffee at 90 ° C. The coffee is too hot to drink. You decide to cool the coffee by dropping ice cubes at -20 ° C in the coffee. How many grams of ice do you need to add to the coffee to cool it down to 60 ° C?
