Pressure, Temperature, Electricity, and Magnetism
Please respond to the following:
· Read the article titled "Aging US Power Grid Blacks Out More Than Any Other Developed Nation" under the Smart Grid terms section of the Science Corner. You can also view the article at https://www.ibtimes.com/aging-us-power-grid-blacks-out-more-any-other-developed-nation-1631086. Next, assess the efficiency of the current state of the national electric grid in the United States. Then, describe the key challenges in updating this grid to a so-called "smart grid".
· Read the article titled "Earth's Inconstant Magnetic Field" under the Earth's Magnetic Field terms section of the Science Corner. You can also view the article at https://www.nasa.gov/vision/earth/lookingatearth/29dec_magneticfield.html. Next, summarize the main reasons why the researchers stated that "our planet's magnetic field is in a constant state of change". Then, discuss the overall manner in which a magnetic reversal might impact human activities on Earth. Include one example of such impact to support your response.
· Demonstrate an instance of static charge such as seen with examples #32 and 33 shown on page 209 of your textbook. Next, post a picture of your example then explain the method of charging you used as well as the charges displayed in each object.
A steel ball is dropped from a building's roof and passes a window, taking 0.13 s to fall from the top to the bottom of the window, a distance of 1.20 m. How tall is the building
An experimental bicycle wheel is placed on a test stand so that it is free to turn on its axle. What is the torque supplied by friction
Two point charges are fixed on the y axis: a negativepoint charge q1 = -28µC at y1 = +0.25m and a positive point charge q2 aty2 = +0.33 m. A thirdpoint charge q = +8.1 µC isfixed at the origin.
What is the maximum speed the masses
Two charges of equal magnitude exert an attractive force of 2.0×10-4 N on each other. If the magnitude of each charge is +2.3 C, how far apart are the charges?
a 0.22-muf capacitor is charged by a 1.5-v battery. after being charged the capacitor is connected to a small electric
We require any information you may have on how plants stay at their distance with out floating away or smashing into one another?
With the temperature held constant, the piston of a cylindercontaining a gas is pulled out so that the volume increases from0.1 m3 to 0.3 m3. what is the final pressure
A ball is dropped (from rest) straight down from atop a 32.0 m cliff. At the same instant, a ball at the ground level below the cliff is thrown straight upwards at a speed such that it would come to a (momentary) stop at the top edge of the cliff. Ho..
A doubly charged helium atom whose mass is 6.6 10 to 27 kg is accelerated by a voltage of 2200 V. What will be its radius of curvature if it moves in the plane perpendicular to a uniform 0.308 T field?
A weather balloon is designed to expand to a maximum radius of 10 meter when in flight at its working altitude where the air pressure is 0.047 atm and the temperature is 258 K. find its radius at liftoff
