1. A 2150 kg satellite used in a cellular telephone network is in a circular orbit at a height of 780 km above the surface of the earth. What is the gravitational force on the satellite? What fraction is this of its weight at the surface of the earth?
2. Calculate the magnitude and direction of the net gravitational force on the moon due to the earth and the sun when the moon is in each of the positions shown in Fig. (Note that the figure is not drawn to scale. Assume that the sun is in the plane of the earth-moon orbit, even though this is usually not the case.) Use the data in Appendix F.
3. Gravitational Field. The gravitation field produced by an object is defined as F→g the gravitational force that the object exerts on a small test particle of mass m divided by m. That is g→= F→g / m. What are the magnitude and direction of the gravitational field produced by a 20.0 kg spherically symmetric object at a point 1.50m directly above the center of the object?
Two and one-half kg of ice at temperature T' = 0ºC is melted into water at the same temperature by placing it in contact with a reservoir at temperature TR = 20.0ºC. find the change in entropy of the ice that was melted
A car with a mass 900kg and velocity 12m/s traveling north isapproaching an intersection. another car with a mass 750kg and avelocity of 9m/s traveling west is approaching the sameintersection.
An oscilloscope shows a steady sinusoidal signal of 5 Volt peak to peak, which spans 5 cm in vertical direction on the screen. What will be observed on the oscilloscope screen
A piece of conductor is moving in a uniform magnetic field B = 0.2 T with a velocity of 0.5 m/s perpendicular to the magnetic field. What is the electromotive force in the conductor
A uniform beam of mass M and length L is pinned to the wall and supported in equilibrium by a thin cable attached a distance d from the free end of the beam. Calculate the force exerted by the pin on the beam in vector form
