kinetic energy of the projectile in kilojoules

Q: atomic nucleus initially moving at 375 m/s emits an alpha particle in the direction of its velocity,…

A: Given  Initial speed = u = 375 m/s  Final speed = v = 250 m/s  Mass of alpha particle = Mh = 4 .0 u…

Q: An object is traveling at a final speed of 12 m/s. What was the initial speed of the object,…

A:

Q: An atom with a mass of 4 x 10-26 kg is given a kinetic energy of 2 x 10-16 J. It then travels a 1 m…

A: Mass of atom (m) = 4×10-26 kg Kinetic energy (K) = 2×10-16 J distance (d) = 1 m

Helmholtz Free Energy

The Helmholtz free energy is a thermodynamic potential used to calculate the measure of useful work from a closed system. This system is kept at constant temperature and volume. German physicist Hermann Helmholtz introduced this concept in 1882.
