Areal steam turbine and its 1st and 2nd law efficiencies 8.8 a steam turbine receives steam at 2500 kpa, 500°c with an exhaust at 500 kpa, 300°c. we would like to find the first law isentropic efficiency, the specific reversible work, the specific irreversibility and the second law efficiency.

unbalanced force

explanation:

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

c. 127 in.2

d. 1,018 in.2

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.
