A jet takes off from SFO to YUL. The distance between the airports is 4100 km. After a 1 hour layover, the jet returns to SFO. The total time for the round trip (including the layover) is 11hr 52 mins. If the westbound trip (from YUL to SFO) takes 48 more minutes than the eastbound portion, calculate the time for each leg of the trip.
What is the average speed of the overall trip?
What is the average speed without the layover?
n = 4.13 mol of Hydrogen gas is initially at T = 335 K temperature and pi = 1.73×105 Pa pressure. How much entropy did the gas emit
A large wood block is being pushed across the floor with a force of 180-N to the right. The block has a mass of 145.00 kg. The frictional force is 45-N. What is the acceleration of the block.
Fleas can jump quite high; experiments show that they reach an altitude of 130 times their own height when they jump vertically! Suppose instead that a flea can jump, What is the take-off speed for this flea
A dentist's mirror is placed 2.1 cm from a tooth. The enlarged image is located 5.7 cm behind the mirror. (a) What kind of mirror (plane, concave, or convex) is being used
An air-filled spherical capacitor is constructed with an inner-shell radius of6.50cm and an outer-shell radius of15.0cm. What potential difference between the spheres results in a 4.00-µC charge on the capacitor
A horizontal block-spring system with the block on a frictionless surface has total mechanical energy E = 42.3 J and a maximum displacement from equilibrium of 0.259 m, Find the potential energy stored in the spring when x = 0.160 m
My professor today stated that if a ball was to fall a certain height, then the work done by gravity on the ball would equal the work done by the ball's equal and opposite gravitational pull. By W=F*d, this means that the earth must travel the ..
