(a)
Interpretation:
Unit cell volume should be calculated
Concept Introduction:
The atomic symbol of bismuth is Bi and has the atomic number of 83. The indium metal is a post transition pentavalent one and the earth has natural bismuth metal. The bismuth oxides and sulfide forms essential ores that are of commercial use. The pnictogens of the metal along with its chemical properties resembles homologs light arsenic and antimony.
(b)
Interpretation:
Atom numbers per unit cell should be calculated.

- Using R languagearrow_forwardCompare the security services provided by a digital signature (DS) with those of a message authentication code (MAC). Assume that Oscar can observe all messages sent between Rina and Naseem. Oscar has no knowledge of any keys but the public one, in the case of DS. State whether DS and MAC protect against each attack and, if they do, how. The value auth(x) is computed with a DS or a MAC algorithm. In each scenario, assume the message M = x#####auth(x). (Message integrity) Rina has the textual data x = “Transfer $1000 to Mark” to send to Naseem. To ensure the integrity of the data, Rina generates auth(x), forms a message M, and then sends M in cleartext to Naseem. Oscar intercepts the message and replaces “Mark” with “Oscar.” Will Naseem detect this in the case of either DS or MAC? If yes, how will Naseem detect it? If not, why? (Replay) Rina has the textual data x = “Transfer $1000 to Mark” to send to Naseem. To ensure the integrity of the data, Rina generates auth(x), forms a message…arrow_forwardFundamentals of Energy Systems HW 4 Q1arrow_forward

The battery state of charge window is 80%. Design the battery by using new commercial cylindrical cells with 20mm diameter and 80mm height. The battery is constructed based on graphite anode C6 and cathode Li(Ni0.8Co0.15Al0,05)O2 that provides 3.75V at the cell level and 10Ah capacity. Density of anode is 2.2 g/cm3 and density of cathode is 4.5 g/cm3. Report on the battery pack configuration if the required battery pack voltage is 75 volts.
