assume you the lead physicst SpaceX and you are asked to calculate the gravitational force that will be acting on a new satellite they plan to launch into Mars. Calculate the force between Mars, which has a mass of 6.39x10^23kg and the satellite, has a mass of 276 kilograms. Assume that NASA wants the satellite to orbit Mars at a distance of 20037 meters.

The extremely high temperatures needed to trigger nuclear fusion are proposed to be generated by laser irradiating a spherical pellet of deuterium and tritium fuel of diameter 1.8 mm. (a) determine the maximum fuel temperature that can be achieved by irradiating the pellet with 200 lasers, each producing a power of 550 w. the pellet has an absorptivity 0.3 and emissivity 0.8.

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
