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 11.0 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 α 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.

(a) what was the original activity of the 238 pu in becquerel?
(b) what power was emitted in kilowatts?
(c) what power was emitted 12.0 y after launch?

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
