Pu Decays by Alpha Emission

Pu decays by alpha emission. The isotope's half-life is 2.4 x 10(exponent 4) yr. How many alpha particles are emitted per second by 25mg of Pu?

Balance a radioactive decay equation to find the charge and nucleons.

In the equation 226/88 Ra--> 4/2 He+ ------, the characteristics of the missing particle are: A) charge, 90; nucleons, 230 B) charge, 86; nucleons, 230 C) charge, 90; nucleons, 222 D) charge, 86; nucleons, 222

Several Problems with different topics: Magnetism, Electricity, etc.

I need the process and the answers to the solutions. Not just the way to get the answers but also the values inserted in the process followed by a Answer = . Please take your time because I've gotten some way off answers and it cost me points on my test because I was mislead on my homework. I wrote this before and I am inclu

Friction: Determine magnitude and direction of force P to start the block up the plane.

See the attached drawing file. The asking problem: A block of weight W=60 lb rests on a rough plane as shown. Knowing that "alpha"= 20° and Us (coefficient of static friction) = 0.30, determine the magnitude and direction of the smallest force P required to start the block up the plane. The answer of this problem for v

Thermal expansion of aircraft carrier in the Mediterranea Sea

A steel aircraft carrier is 370m long when moving through the icy North Atlantic at a temperature of 2.0 degrees Celsius. By how much does the carrier lengthen when it is traveling in the warm Mediterranean Sea at a temperature of 21 degrees Celsius?
