Being socially competent is a crucial skill that most people seek to master, but there is evidence to support the notion that social media is actually damaging people’s ability to engage with competence in an offline setting. For example, various research studies highlight the social competency of youths who spend much of their time on social media networks. However, the findings are somewhat conflicting. In your first post, address the following: Identify whether your general impression of social media is positive or negative and explain the role social media has played in your life.Some professors require students to use social media for their coursework. What are your views on this trend in education?Discuss and provide an example of the way social media affects today's society. Be specific. What are the pros and cons of social media for individuals? For businesses?Does the use of social media increase or decrease social change? Which of the five types of social movements do you think occur most often as a result of social media?

Work by subsequent researchers consistently suggested that while the viral proteases had a Cys and His in the active site that functioned similar to the Ser and His of serine proteases, the viral proteases lacked the Asp that makes up the third part of the serine protease catalytic triad. Based on this information, draw a reasonable mechanism for how the viral proteases catalyze the cleavage of a peptide bond (use R1 and R2 to represent the side chains of the amino acids on either side of the cleaved peptide bond).

Texts: I ONLY NEED PART C DO NOT SOLVE A OR B AND POST ANSWERS, JUST PUTTING THOSE FOR REFERENCE AND PUTTING ANSWERS AS WELL 1a) Suppose a spring is constructed that DOESN’T obey Hooke’s law, but instead exhibits a restoring force given by Fx = −kx^3 where k = 4 Nm^3 (it needs these units so that force is newtons). How much work is done to stretch this spring by 0.10m from equilibrium? ANS: 0.0001 J 1b) The spring in the previous problem is released from that stretched position with a 0.20kg mass attached. Assume the whole arrangement is horizontal so that gravity isn’t doing work. How fast will the mass be moving when the spring once again reaches equilibrium length? V = 0.447 m/s 1c) Suppose in the prior problem that the mass attached to the spring experiences a little sliding friction as it slides across a horizontal surface while being pulled by the spring. If μ = 0.05, how fast will the mass be moving when the spring reaches equilibrium length?
