Aproton accelerates from rest in a uniform electric field of 700 n/c. at one later moment, its speed is 1.10 mm/s (nonrelativistic because v is much less than the speed of light). (a) find the acceleration of the proton. m/s2 (b) over what time interval does the proton reach this speed? s (c) how far does it move in this time interval?

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.

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm

Acamcorder has a power rating of 20 watts. if the output voltage from its battery is 9 volts, what current does it use?
