Q. A 465 g ball swings in a vertical circle at the end of a 1.3 m-long string. When the ball is at the bottom of the circle, the tension in the string is 21 N. What is the speed of the ball at that point?
Q. A tuning fork produces a sound with a frequency of 249 Hz and a wavelenght in air of 1.35 m. What value does this give for the speed of sound in air? Answer in units of m/s.
A hydrometer is used to measure the specific gravity of liquids. For a sure liquid a hydrometer reading indicates a specific gravity of 1.15. What is the liquid's density and specific weight? State the answer in SI units.
A U-shaped tube is open to the air at both ends and is partially filled with Mercury (density = 13,600 kg/m3). Water (density = 1000 kg/m3) is poured into the left arm until the water is 10 cm deep. How long upward from its initial position does t..
A car is moving at a constant velocity for 3s until it is 3.0 m from a yellow light. It slows to a stop in 2.0s. It remains stopped for 50s and then speeds up for 2s.
How many 111 W lightbulbs can you use in a 107 V circuit without tripping a 16 A circuit breaker? (The bulbs are connected in parallel, that means that the potential difference across each lightbulb is 107 V.)
