Present theory suggests that giant planets cannot form without condensation of water ice, which becomes vapor at the high temperatures close to a star. so how can we explain the presence of jovian-sized exoplanets closer to their star than mercury is to our sun?

What tightening torque should be used for a hexagonal head screw (not split-bolt) on a 250 kcmil conductor?

Avery long solenoid of inner radius 2.75 cm creates an oscillating magnetic field of the form = for this solenoid, =0.00425 t and =319 rad/s. (a)what is the maximum value of the induced electric field at a perpendicular distance 1.45 cm from the axis of the solenoid? (b) what is the maximum value of the inducted electric field at a point 5.85 cm perpendicular from the axis of the solenoid?

3. a lunar exploration vehicle was created by a research team. it weighs 3,000 kg on the earth. it needs an acceleration of 10 m/s2 on the moon. in order to have the same acceleration, what will be the net force acting on the vehicle on the earth?
