Q. A baseball is seen to pass upward by a window 15 m above the street with a vertical speed of 18 m/s. Assume the ball was thrown from the street. What was it's initial speed?
Q. Four conducting cylinders shown below are all made of the same material, although they differ in length and/or diameter. The cylinders are connected to four different batteries such that each circuit has the same current. Rank the voltage across each cylinder, from greatest to least.
The rectangular gate CD shown in the figure is 1.8 m wide and 2 long. Assuming the material of the gate to be homogeneous and neglecting friction at the hinge C, determine weight of the gate necessary to keep it shut until the water level rises to..
Standing at a crosswalk, you hear a frequency of 520 Hz from the siren of an approaching police car. After the police car passes, observed frequency of the siren is 455 Hz. Establish the car's speeds from these observations.
Iced tea is made by adding ice to 2.4 kg of hot tea, initially at 70?C. How many kg of ice, initially at 0?C, are required to bring the mixture to 10?C? (Lf = 3.33×105 J/kg, cw = 4,186 J/kg•? C)
A series ac circuit is shown. The inductor has a reactance of 80 Omega and an inductance of 200 mH. A 90- Omega resistor and a capacitor whose reactance is 130 Omega , are also in circuit. The rms current in the circuit is 1.3A. What is the phase ..
Take the mass of the sun to be m_s = 1.99×1030 {rm kg}, gravitational constant to be G = 6.67×10-11 {rm N} cdot {rm m^2/kg^2}, and an acceleration due to gravity at the earth's surface to be g = 9.810 {rm m/s^2}.
