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 (1) 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.
Two point charges, +3.18 µC and -6.65 µC, are separated by 1.13 m. What is the electric potential midway between them
a block of mass M=46 kg slides down a frictionless inclined plane and collides elastically with another block of mass m=25.0 kg. what is the velocity of m after the collision
You create a plot of a (in m/s2) vs sin ? and the linear fit of your graph gives a slope of 9.7260 ± 0.3100.
A piston performs reciprocal motion in a straight line which can be modelled as s.h.m its velocity is 20 m/s when the displacement is 80 mm from the mid-piston, and 4 m/s when the displacement is 160 mm from the mid piston. Determine the frequency..
A puck with mass m = 0.14kg slides along a frictionless horizontal surface at v = 5.9 m/s. It hits and sticks to the free end of a spring with k = 15 N/m. Find the period of the subsequent simple harmonic motion
If an airplane accelerates at 10 m/s2 for 12.3 seconds. How far has the plane traveled in that amount of time
A glass flask whose volume is 1000cm3 at a temperature of 0.500?C is completely filled with mercury at the same temperature. compute the coefficient of volume expansion of the glass
A water pipe having a 2.4 cm inside diameter carries water into the basement of a house at a speed of 0.95 m/s and a pressure of 174 kPa. What is the water pressure at the second floor
A rocket is launched at an angle of 56.0° above the horizontal with the initial speed of 101 m/s. The rocket moves for 3.00 s along its initial line of motion with an acceleration of 28.0 m/s2. At this time, its engines fail and the rocket proceeds..
To enter the main pool at an amusement park, a swimmer use a water slide which has a vertical height of 2.41 meter. Determine her speed at the bottom of the slide
A 0.300 kg ball is thrown vertically upward with an initial speed of 16.0m/s. What is the maximum height reached by the ball
In an angle of repose experiment a block is held near thetop of an inclined plane (length = 100 centimeters). Calculate the coefficient of friction for the block on the plane
