Objects with masses of 130 kg and a 430 kg are separated by 0.300 m.(a) find the net gravitational force exerted by these objects on a 35.0 kg object placed midway between them.(b) at what position (other than infinitely remote ones) can the 35.0 kg object be placed so as to experience a net force of zero?

Alightning strike consists of charge moving from a cloud to the ground . in one particular case, the electrons in a lightning strike are confined to travel within a radius of 1.5 m and to move at a speed of 5.0 x 10 m/s. if the density of electrons in the strike is 10'15 electrons/m what current is carried by the lightning ?

Akg a of 55 m at an of 11 ? . if is at 98 km/h, be ?

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
