Answer:
Isolated system
Explanation:
By definition of a closed system it means that a system that does not interact with it's surroundings in any manner
The other options are explained as under:
Isothermal system : It is a system that does not allow it's temperature to change
Control Mass system : It is a system whose mass remains conserved which means the mass entering the system equals the mass leaving the system
Open system: It is a system that allows transfer of mass and energy across it's boundary without any opposition i.e freely.
Answer:
Grade is 10.32%
Explanation:
Given data:
stopping side distance is 800ft
t = 2.5 sec
design speed v = 65 miles/hr
a/g value is 0.35
stopping side distance is SSD
plugging all value for G
G = 0.1032
Grade is 10.32%
To solve this problem, we must simply use the concept of Total Energy transferred both in terms of work and heat. This is basically conjugated in the first law of thermodynamics.
If we take the heat absorbed as positive and the expelled as negative we have that the total work done in the heat engine is
For the case of the engine pumps the Energy absorbed is
In this way the ratio between the two would be
So it is reversible, because the state of efficiency of the body is totally efficient.
Answer:
An arrow
Explanation:
An interdisciplinary approach to architectural designs is more concerned with
ideas combined towards the outcome of the project without dividing a design based on different artistic approaches. The goal here is to have an open mind aware of the transdisciplinary in the area of architectural design. The belief is to attain a design which as a real social value with respect to the fact that architectural designs are increasingly influenced by urban factors. An arrow in the quiver is an idiom which means different strategies that could be used to achieve your objectives. This can be compared to the different artistic approaches that could combine to produce the desired architectural design.
Answer:
max shear = R = V = 15 kN
Explanation:
given:
load = 10 kn/m
span = 3m
max shear = R = V = wL / 2
max shear = R = V = (10 * 3) / 2
max shear = R = V = 15 kN
