You are designing a precision mercury thermometer based on the thermal expansion of mercury (?=1.81?10?4°C?1), which causes the mercury to expand up a thin capillary as the temperature increases. The equation for the change in volume of the mercury as a function of temperature is ?V=?V0?T, where V0 is the initial volume of the mercury and ?V is the change in volume due to a change in temperature, ?T. In response to a temperature change of 1.00°C, the column of mercury in your precision thermometer should move a distance D=1.33cm up a cylindrical capillary of radius r=0.133mm.
a) Determine the initial volume of mercury that allows this change.
b) Find the radius of a spherical bulb that contains this volume of mercury.
Light of intensity 2.5W/m2 passes through the pupil of one of your eyes and eventually falls on your retina. The radius of the pupil is controlled by the iris.
Two point charges are located on the axis as follows: charge = -2.00 at = -0.500 , and charge = 2.80 at the origin ( = 0). What is the magnitude of the net force exerted by these two charges on a third charge = 9.00 located at = 0.250?
how high above the target must the rifle barrel be pointed.
A rectanbular tank is placed on wheels and is given a constant horizontal acceleration a. display that, at steady state, the angle made by the free surface with the horizontal is given by tan(delta)=a/g.
One way to measure on another planet or moon by remote sensing is to measure how long it takes an object to fall a given distance. A lander vehicle on a distant planet records the fact that it takes 3.17 for a ball to fall freely 11.26.
What is the length of the shadow cast on the vertical screen by your 9 cm hand if it is held at an angle of 20 above horizontal.
A helicopter is rising at 4.60 m/s when a bag of its cargo is dropped. The bag falls for 2.50 s. (suppose that the positive direction is upward.)
A mass ball is attached to the spring and allowed to come to rest. It is then pulled down y and released. Illustrate what is the time constant if the ball's amplitude has decreased to y1 after oscillations?
The yellow light from a helium discharge tube has a wavelength of 587.50. When this light illuminates a certain diffraction grating it produces a first-order principal maximum at an angle of 1.050.
A 0.100 kg meterstick is supported at its 40 cm mark by a string attached to the ceiling. A 0.700 kg mass hangs vertically from the 5 cm mark.
Three point charges are arranged at the corners of a square, with charge -Q on both the particle at the upper left corner and the particle at the lower right corner and with charge +2Q on the particle at the lower left corner.
A spacecraft is traveling with a velocity of vox = 5675 m/salong the +x direction. Two engines are turned on for a time of 847 s. One engine gives the spacecraft an acceleration in the +x direction of ax = 1.25 m/s2,while the other gives it an acc..
