What term is defined as splitting large nuclei into smaller ones
svetoff [14.1K]

Answer:

Nuclear Fission.

Explanation:

This happens when a high-energy particle collides with a radioisotope, which splits into 2 daughter nuclei, several neutrons (which can collide with more radioisotopes to cause a chain reaction); and a lot of energy. That's why nuclear power plants are so good.

The temperature in your town is 31°F. The radio announcer says that the temperature will drop 15 degrees. What will the temperat
hoa [83]

Answer:

The temperature of the town will be 15°F.

The equation showing the final temperature after drop say x degrees can be written as:

T'=(T-x)^oF

Explanation:

The current temperature in our town = T = 31°F

Temperature drop suggested by radio announcer = 15°

Temperature of the town after temperature drop = T'

T'=T-15^oF

T'=31^oF-15^oF=16^oF

The equation showing the final temperature after drop say x degrees can be written as:

T'=(T-x)^oF

A non-mechanical, rigid, and fully insulated mixing tank is used to combine two inflows to produce wet steam. One inflow consist
Bogdan [553]

Explanation:

As it is given that stream A is super heated. From stream tables, we get that specific enthalpy, (h_{A}) is 3054.29 kJ/kg.

For stream B, it is saturated water at 25 degree celsius. It's h_{B} is 2546.54 kJ/kg.

Stream C, data will be as follows.

                P = 200 kPa,         \chi = 0.9

So, h_{c} = h_{f} + \chi \times h_{fg}  

        = 504.47 + 0.9 \times 2201.7

        = 2486 kJ/kg

Now, energy balance formula will be as follows.

            m_{A}h_{A} + m_{B}h_{B} = (m_{A} + m_{B})h_{c}

              3 \times 3054.29 + m_{B} \times 2546.54 = (3 + m_{B}) \times 2486

             m_{B} = 28.16 kg/s

Hence, inflow of saturated liquid is 28.16 kg/s. According to steam table, temperature of wet steam is 120.23^{o}C

Mass flow rate of out flow is 31.16 kg/s.
