A motorboat heads due east at 12.0 m/sacross a river that flows toward the southat a speed of 4.1 m/s.What is the angle from the original heading(with counterclockwise positive) of the boat’sdisplacement?
A bathysphere used for deep sea exploration has radius of 1.5mand a mass of 1.20*104kg. In order to dive, the spheretakes on mass in the form of sea water. Determine the massthe bathysphere must take on so that it can descend at a constantspeed of 1.20m/s when the resistive force on it is 1100Nupward. the […]
2500 kg/hr of a mixture containing equal parts by mass of benzene and toluene are distilled. The flow rate of the overhead product stream is 988 kg/hr , and the bottom stream contains 17.03 wt% benzene. Draw and label a flowchart of the process. Then calculate the mass and mole fractions of benzene and the […]

Suppose that a penny has enough electrons removed from it to acquire 1.00 C of charge. (a) What fraction of its electrons must be removed to acquire this charge? (b) If the excess charge is deposited on a second penny and the pair is placed 1.00 km apart, what is the resulting force between them? […]
Question 8Suppose SPT rule is being used in a “dynamic” scheduling problem. There are five jobs A,B,C,D, and E ready to be processed at the present time. The processing times for the five jobs are 1, 9, 7, 2, and 6 days respectively. A new job F will arrive on the 8th day. The processing […]
Derive the formula for F3 in terms of the experimentally measured quantities m1, m2, 1, and 2.[Answer: F3=m1gcos1+m2gcos2.]Make sure you understand how this formula was derived.QUESTION:If the mass of both weights is 175 gm, the first mass is located 30 north of east, the second mass is located 30 south of east, and the transducer […]
In horse, black coat color is influenced by the dominant allele (B) and chestnut coat color by the recessive color(b). Trotting gait is due to dominant gene (T), pacing gait to the recessive allele (t). what color horse would you use to find out the genotype of black trotter? what are the phenotype?
You hold a meterstick horizontally with the same mass suspended at the end. Rank the torque needed to keep the stick steady; from largest to smallest.A. Meterstick is held at a 45 degree angle, upward, with weight suspended at the end.B. Meterstick is held horizontally(left to right and in a straight line), with weight suspended […]
A plastic ring has a radius R = 50.0 cm. Two small charged beads are on the ring. Bead 1 of charge +2.00 uC is fixed in place at the left side of the ring. Bead 2 of charge +6.oo uC can be moved along the ring. The two beads produce a net electric field […]
