Answer:
The length of the tube is 3.92 m.
Explanation:
Given that,
Electric potential = 100 MV
Length = 4 m
Energy = 100 MeV
We need to calculate the value of
Using formula of relativistic energy
Put the value into the formula
Here,
We need to calculate the length
Using formula of length
Put the value into the formula
Hence, The length of the tube is 3.92 m.
Answer:
B. Landscape B
Explanation:
Shale is fine sediment pressed together to form rock.
Sandstone is larger (sand-grain-sized) sediment cemented together to form rock.
Shale erodes faster, as evidenced by the second attachment. That attachment shows erosion of a rock face consisting of interbedded shale and sandstone. The shale has receded significantly, leaving the sandstone layers with space between them.
To solve this problem, it is necessary to apply the concepts related to the Energy balance and the mass balance that allow us to find in each state the data necessary to find the total Power of the system through heat exchange.
From the tables of properties of the Water it is possible to obtain at the given pressures the values of the specific volume, the specific energy and the specific enthalpy.
Given these pressures then we have to
Saturated vapor
Saturated vapor
Considering the process performed, the kinetic and potential energy can be neglected as well as the work involved by specific interactions in the system. Although it is an unstable process it can be treated as a uniform flow process. Considering these expressions we can perform a mass balance for which
Similarly through the energy balance you can get that
Since
The initial mass, initial internal energy, and final mass in the tank are
At the same time the internal energy can be defined from the mass in state 1 as,
The calculation of mass in state 2 can be defined as
Then from the mass and energy balances,
In this way the calculation of the heat of entry would be subject to
Therefore the Power would be given as
Therefore the highest rate of heat transfer allowed is 1.163kW
