Aspaceship is traveling through deep space towards a space station and needs to make a course correction to go around a nebula. the captain orders the ship to travel 1.1x10^6 kilometers before turning 70° and traveling 2.3x10^6 kilometers before assuming the path towards the space station. if the captain had not ordered a course correction, what would have been the magnitude and direction of the path of the spaceship if it had traveled through the nebula?

magnitude km

direction ° counterclockwise from the +x-axis

Find the momentum for a 2.6-kg brick parachuting straight downward at a constant speed of 8.4 m/s .

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.
