please show work/formulas and answers so I can understand where the numbers and such are coming from. thanks! One of the main contributing factors to the extinction of the dinosaurs 65 million years ago was a large comet or asteroid that struck the earth. It threw up so much dust that the sun was blocked for a period of many months. Suppose the asteroid had a mass of 2.0 x 1013 and hit the earth (mass = 6 x 10...
A graph for angle (radians) vs. time (seconds) for a turntable with a 0.25 radius is shown below. a.) Describe what the turntable is doing during the times shown. b.) Estimate how fast the turntable is rotating at t=0. c.) Draw an angular velocity vs. time graph that matches this. d.) Determine the angular acceleration. * I couldn't upload the graph, but these are the points: at 1 rad, 0 sec; at 2.5 rad, 1 sec; at 2.75, 2 sec;...
I had already posted this but did not understand the answer. Please show all work and steps thanks! Problem 4. Solve the linear non-homogeneous equation for r = r(t) with initial conditions ë+ 4.+ 5x = 10t + 13, 2(0) = 2, i(0) = 0.
A vertical wheel with a diameter of 50 cm starts from rest and rotates with a constant angular acceleration of 4 rad/s? around a fixed axis through its center counterclockwise. a. Where is the point that is initially at the bottom of the wheel at t = 5 s? Round your answer to one decimal place and express it as an angle in radians between 0 and 2π, relative to the positive x axis. b. What is the point's linear acceleration at...
Please show all work and formulas used. Thanks! 1. (a) Write the reaction between alum and alkalinity. Show that 1 mg/L of alum reacts with 0.5 mg/L of alkalinity as CaCO3 and produces 0.26 mg/L of Al(OH)3 and 0.44 mg/L of CO2. (b) Write the relevant equation and the mg/L relationship for Ferric Chloride.
