1. The gravitational force due to the Sun on the planets in our solar system decreases as the planetary distance from the Sun increases. In your notebook, draw a larger version of Figure 3, and complete it for the force of gravity on an imaginary Earth-mass planet if its distance were between the Sun's radius, rs, and 100rs.
2. A metal-coated table tennis ball with a mass of 2.1 g is suspended by an insulating thread. A similar table tennis ball touches the first, giving each ball an equal negative charge. When the two balls are separated horizontally by 5.0 cm, the string hangs at 15° with respect to the vertical.
A power outage occurred at a water distribution pump station. Before the power outage the station was pumping with one pump at 6,000 gpm in a 18" diameter Steel Pipe
A car is driven along a straight track with position given by s(t) = 150t – 300 ft (t in seconds). Find v(t) and a(t). Use calculus to find the displacement and total distance traveled over the interval [1, 4].
steam at 2.5 mpa and 400 c enters an adiabatic steam turbine with a low velocity and leaves with a velocity of 180 ms
estimate the nominal size of the smallest sae grade 1 standard unc bolt that will not yield under a tightening torque
If you attach torsion spring to inverted pendulum, is this the equation of motion? The spring is attached on one end to a pivot point and also at the pivot point the spring is attached. I used L/2 for the location of the center of mass.
you are designing a mobile device to extract water from a well through a tube. assume your device is able to create a
For an adiabatic in viscid flow, write the entropy equation in general coordinate-independent form and in Cartesian coordinates. What does the equation express? Can we say that entropy is constant in an entire such flow (explain your answer)?
On a hot summer day, a student turns his fan on when he leaves his dorm room in the morning. The dorm is well insulated but not air conditioned, and all of the doors and windows are closed. Draw a simple picture of this room after the student leaves ..
A vibrometer has an undamped natural frequency of 10Hz. and damped natural frequency of 8 Hz. Find the lowest frequency in the range to infinity at which the amplitude can be directly read from the vibrometer with less than 2 percent error.
The car travels at a constant speed of 25 m/s makes a turn on a semi-circular curve. If it takes 20s to make the semi-circular turn, determine the magnitude of the car’s acceleration during the turn.
