Answer:
Explanation:
Answer is in the following attachment
Explanation:
40.4m
Explanation:
Pressure at depth is given as
P = P, + pgh
Final pressure at depth h= 5 Po
5Po= Po + pgh
pgh = 4Po = 4 x 1.01 x 10^5
h = (4.04×10^5)/ (1000x10)
h=40.4m
Answer:
The relationship between atomic structure and Youngs modulus could be defined as the stiffness of a material.
Explanation:
Young modulus is a constant that shows how a material can be deformed under a stress applied on certain material and also shows its stiffness, this deformation will change or not its atomic structure depending on the capability of material to recover from the stress applied. The stiffness of a material is directly proportional to Young's modulus, as well as its atomic structure, if a material has high stiffness, it won't bend so easily and it won't change its atomic structure easily.
Answer:
Explanation:
From the given information:
Strain fracture toughness = 75 MPa
Tensile stress = 361 MPa
Value of Y = 1.03
Thus, the minimum length of the critical interior surface crack which will result to fracture can be determined by using the formula:
Answer: B) High chemical energy and low molecular weight
Explanation: Liquid propellant is a a single chemical compound or mix of other chemicals as well. It is used in the rocket that uses them as a major part for the fuel. A liquid propellant is supposed to have high chemical energy and low molecular weight so that is can be ignited with ease. High chemical energy can release good amount of heat in a chemical reaction and thus is good igniting compound for the liquid propellant rocket.
