You are exploring a new planet, Uzaz. You have a string 1.2 m long, and a small object. You suspend the object from the string, and you observe that small-amplitude pendulum swings have a period of 1.987 s. You have determined the radius of Uzaz is 7.2 × 106 m. You then launch the object at an angle θ above the horizontal from shoulder-height (1.40 m) with a velocity of 30 m/s; it hits the ground 60.36 m from you. Assume the ground is level and ignore atmospheric resistance.

(a) (5 points) Determine the mass of planet Uzaz.

(b) (4 points) Determine all possible angles θ above the horizontal at which you could have launched the object.

You have a column of air 1.2 m long. The hard bottom of the tube forces a node there and the open end at the top of the tube forces an antinode there. Sound waves from a 1024 Hz tuning fork are sent down the column. Compute the wavelengths and frequencies for the first three allowed harmonics within the column.

A closed rectangular tank 1.2 m high, 2.4 m long and 1.5 m wide is two-thirds full of gasoline (specic gravity 0.8). Calculate the acceleration which may be imparted to the tank so that the bottom front end of the tank is just exposed. Also calculate the total forces on each end of the tank and show that the dierence between these forces equals the unbalanced force necessary to accelerate the liquid mass in the tank.

An aluminum rod with a square cross section is 1.2 m long and 5.0 mm on edge. (a) What is the resistance between its ends? (b) What must be the diameter of a cylindrical copper rod of length 1.2 m if its resistance is to be the same as that of the aluminum rod? The resistivity of aluminum is 2.75 × 10-8 Ω·m and the resistivity of copper is 1.69 × 10-8 Ω·m.

An astronaut is exploring an unknown planet when she accidentally drops an oxygen canister into a 1.90-m-deep pool filled with an unknown liquid. Although she dropped the canister 46 cm from the edge, it appears to be 56 cm away when she peers in from the edge. What is the liquid's index of refraction? Assume that the planet's atmosphere is similar to earth's.

A 5.11-kg ball hangs from the top of a vertical pole by a 2.33-m-long string. The ball is struck, causing it to revolve around the pole at a speed of 4.47 m/s in a horizontal circle with the string remaining taut. Calculate the angle, between 0° and 90°, that the string makes with the pole. Take g = 9.81 m/s2.

A 5.47-kg ball hangs from the top of a vertical pole by a 2.13-m-long string. The ball is struck, causing it to revolve around the pole at a speed of 4.75 m/s in a horizontal circle with the string remaining taut. Calculate the angle, between 0° and 90°, that the string makes with the pole. Take g = 9.81 m/s2. Answer in degrees. What is the tension of the string? Answer in N
