Can you please help me set this problem up? Suppose that now you want to make a scale model of the solar system using the ball bearing .0014 m to represent the sun. (a) How far from it would you place a sphere representing the earth? (Center to center distance please.) The distance from the center of the sun to the center of the earth is 1.496×10^(11) m and the radius of the sun is 6.96×10^(8) m. (c) What would be the radius of the sphere representing the earth in part (a)? Answer needs to be in m units and (± 2E-7 m)
A horizontal pipe contains water at a pressure of 150 {rm kPa} flowing with a speed of 1.30 {rm m/s}. The pipe narrows to one-half its original diameter. What is the speed of the water.
When subject to a steady acceleration of 0.800 g, the object must be located 0.600cm from its equilibrium position. Find the force constant required for the spring.
define the magnitude of the initial velocity. use 9.81 m/s^2 for the acceleration due to gravity on earth.
A factory worker pushes horizontally to the right on a 250 N crate with a force of P = 75.0 N on a horizontal rough floor. A 135 N crate rests on top of the one being pushed and moves along with it. Call the bottom crate {rm A} and the top crate {..
Draw a picture of a moving source and the waves surrounding it according to what you observed in this experiment. How does the spacing of the wavefronts in front of the source compare to those behind it?
At high noon, the Sun delivers 1.10-kW to each square meter of a blacktop road. If the hot asphalt loses energy only by radiation, what is its equilibrium temperature.
A 220 g air-track glider is attached to a spring. The glider is pushed in 12cm against the spring, and then released. A student with a stopwatch finds that 16 oscillations take 11.5.
An oscillator with a mass of 530 g and a period of .80 s has amplitude that decreases by 2 percent during each complete oscillation. At what time will the energy be reduced to 33 percent of its initial value.
A plane leaves the airport in Galisto and flies 175 km at 68.0^circ east of north and next changes direction to fly 260 km at 48.0^circ south of east, after which it makes an immediate emergency landing in the pasture.
A Carnot engine whose cold reservoir temperature is 1.0 C has a thermal efficiency of 40%. By how much should the temperature of the hot reservoir be increased to raise the efficiency to 60%?
In a head on collision, a car stops in .10 seconds from a speed of 14 meters per second. The driver has a mass of 70 kg, and is, fortunately, tightly strapped into his seat. What force is applied to driver by his seat belt during that fraction of ..
Two horizontal curves on a bobsled run at the similar angle, but one has twice the radius of the other. The safe speed (no friction needed to stay on the run) for the smaller radius to curve is v. What is the safe speed on the larger radius curve.
