Aprobe orbiting venus exerts a gravitational force of 2.58 ×  103 n on venus. venus has a mass of 4.87 ×  1024 kg. the mass of the probe is 655 kilograms.  to three significant digits, the probe is × 106 m from the center of venus.

Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 93 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 15.5 kw from the compressor to its surroundings. assuming the ideal gas model for air neglecting kinetic potential energy effects, determine the power in put in kw.

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant

Two forces produce equal torques on a door about the door hinge. the first force is applied at the midpoint of the door; the second force is applied at the doorknob. both forces are applied perpendicular to the door. which force has a greater magnitude?
