A molecule of DNA (deoxyribonucleic acid) is 2.28 µm long. The ends of the molecule become singly ionized: negative on one end, positive on the other. The helical molecule acts like a spring and compresses 1.15% upon becoming charged. Determine the effective spring constant of the molecule.
The tractor beam exerts a constant force of 4.0 104 N on the shuttlecraft. Both spacecraft are initially at rest. Explain how far does the starship move as it pulls the shuttlecraft aboard?
A world class sprinter accelerates to his maximum speed in 3.80 s. He then maintains this speed for the remainder of a 100 m race, finishing with a total time of 10.30 s. What is the runner's average acceleration throughout the first 3.80 s.
A candle is placed 16.0 cm in front of a convex mirror. When the convex mirror is replaced with a plane mirror, the image moves 7.5 cm farther away from the mirror. Find out the focal length of the convex mirror.
A uniform ladder 15 ft long is leaning against a frictionless wall at an angle of 56° above the horizontal. The weight of the ladder is 35 pounds. A 77 lb boy climbs 6.0 ft up the ladder. What is the magnitude of the friction force exerted on the lad..
A Carnot engine operates between temperatures of 747 and 324 K. Calculate what the efficiency would be if (a) the temperature of the hot reservoir were raised by 42.5 K or (b) if the temperature of the cold reservoir were lowered by 42.5 K. (Give ..

Two heavy pendula of mass m are suspended from strings of length l inside a railroad car of mass M that can roll freely on horizontal tracks (ignore the moment of inertia of the wheels).
A certain car battery with a 12.0 V emf has an initial charge of 115 A·h. Assuming that the potential across the terminals stays constant until the battery is completely discharged, for how various hours can it deliver energy at the rate of 110 W.
An ocean liner leaves New York City and travels 12.0° north of east for 111 km. How far east and how far north has it gone? In other words, what are magnitudes of the components of the ship's displacement vector in the directions.
