Calculate the force of gravitational attraction between the EARTH and 2 points a GPS satellite. The satellite is orbits 35,786km above the Earth's surface
(that's the "altitude"). The Earth's radius, R_earth, is 6371000m. WHAT IS
THE SEPARATION DISTANCE, R, BETWEEN THE CENTER OF THE EARTH TO
THE CENTER OF THE SATELLITE? ANSWER MUST BE IN METERS. R_total =
R_earth +R_altitude *

Thomas his older brothers, who own a junk yard, on the weekends to earn extra money. he likes to them push broken-down cars to the back of the junk yard because it makes him feel strong. last saturday, they pushed three cars with different weights, and he noticed he used different amounts of force for each one. the cars were the following weights: white car: 2,700 kg red car: 1,500 kg blue car: 2,100 kg think about how much force is needed to move each car. which correctly lists the cars in order from the most to least amount of force needed to move them? a) white, blue, red b) blue, red, white c) red, white, blue d) white, red, blue

What tightening torque should be used for a hexagonal head screw (not split-bolt) on a 250 kcmil conductor?

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.
