The galileo space probe was launched on its long journey past several planets in 1989, with an ultimate goal of jupiter. its power source is 15.6 kg of 238 pu, a by-product of nuclear weapons plutonium production. electrical energy is generated thermoelectrically from the heat produced when the 5.59-mev a particles emitted in each decay crash to a halt inside the plutonium and its shielding. the half-life of 238 pu is 87.7 years. (the atomic mass of 238 pu is 238.05 u.) (a) what was the original activity of the 238 pu in becquerel? bg (b) what power was emitted in kilowatts? kw (c) what power (in kw) was emitted 13.0 y after launch? you may neglect any extra energy from daughter nuclides and any losses from escaping y rays. kw

The sun’s mass is 2.0×10^ 30 kg, its radius is 7.0×10 5 km, and it has a rotational period of approximately 28 days. if the sun should collapse into a white dwarf of radius 3.5×10 3 km, what would its period be if no mass were ejected and a sphere of uniform density can model the sun both before and after?

Ahanging spring stretches by 35.0 cm when an object of mass 450 g is hung on it at rest. in this situation, we define its position as x = 0. the object is pulled down an additional 18.0 cm and released from rest to oscillate without friction. what is its position x at a moment 84.4 s later? express your answer in cm.
