  1) A book on a table has a weight of 9.0 N. A force Ps = 3.0 N is required to start it sliding. But to keep it sliding at a constant speed, a minimum force Pk = 2.0 N is required.  Find: a) the coefficient of static friction and b) the coefficient of kinetic friction. Ans. a. 0.33 b. 0.22  21) An object is moving on a curved path at a linear speed v = 30.0 m/s in a circle of radius r = 2.00 m. The object’s mass is m = 0.100 kg. Find the centripetal force. Ans. 45.0 N   29) The mass of the earth is, ME = 5.98 x 1024 kg, and the mass of the moon, MM = 7.36 x 1022 kg. The distance between their centers is 3.82 x 108 m. How far from the center of the earth is the center of mass of the Earth-Moon system? Ans. 4.64 x 106 m. [the radius is the earth is 6.37 x 106 m, placing the center of mass inside the earth.] SOLUTIONS  (1) (a) The coefficient of static motion is described as the maximum ratio obtained between applied force and the normal force of a body in a s...

  1.       Discuss how the history of today's megatrends and national trends have shaped Canada and the world as we know it today. The technology of discussion, in this case, is Skype, which is a telecommunication app or video-calling software that allows individuals to 'meet' virtually. It enables people to hold high-quality calls or interact using computers, mobile phones, or other communication devices. This technology is commonly used in Canada and worldwide due to its numerous benefits. It enables people to interact face-to-face effectively without necessarily traveling to hold physical meetings. Based on Marshall McLuhan's "Tetrad Analysis," communication technology that led to the emergence of Skype underwent a series of megatrends and national trends throughout history, shaping Canada and the world as a whole (Islas, 2016). On this note, the trends align with McLuhan's Tetrad assessment, where he opines that people's culture and technology foll...

A picture of COVID-19 Virus Introduction As the COVID-19 cases continue to increase, researchers and experts are working tirelessly to find treatments and vaccines to reduce the spread of the disease and the burden it puts on clinical facilities. Some of these treatments are medicines, which have been approved for viruses with similar symptoms. Experts are interested in whether available antivirals or new drugs will be effective in curing the virus. As from May 2020, a medicine that sedates people when they are on a ventilator and hydroxychloroquine and chloroquine were approved for the treatment of COVID-19. However, later on, their use was revoked after the studies revealed that they are not treating COVID-19. Though they are still being tested to determine whether they can treat COVID-19 patients. The clinical trials of any vaccine are important to ensure the drug is safe for use. The development of vaccines for COVID-19 treatment may take months or a year before they become a...
