Answer:
533.92 m/s
Explanation:
The root-mean-square speed of a gas is given by v = √(3RT/M)
R = molar gas constant = 8.3145 J/mol-K
T = Temperature = 320 K
M = Molar mass of Nitrogen in kg/mol = 2 × 14 × 10⁻³ kg/mol = 28 × 10⁻³ kg/mol
v = √(3RT/M) = √(3 × 8.3145 J/mol-K × 320 K/28 × 10⁻³ kg/mol) = √7981920/28 = √285.068.57 = 533.92 m/s
Answer:
70.7m/s
Explanation:
V = ( v + u)
_____
2
V = average velocity
v = final velocity
u = initial velocity
velocity = distance
______
time
u (initial velocity) = 33 ÷ 2
change mins to seconds
1 min = 60 secs
2 mins = ?
cross multiply
60 × 2 = 120 secs
u = 33 ÷ 120
u = 0.275m/s
v ( final velocity) = 29 ÷ 1.3
change mins to secs
1 min = 60 secs
1.3 mins = ?
cross multiply
1.3 × 60 = 78 secs
v = 29 ÷ 78
v = 0.371 m/s
V = ( v + u )
_____
2
V = ( 0.371 + 0.275)
____________
2
V = 0.51 m/s
Explanation: Well, think about it if you see it on the logical end, there are 8 men that mean 16 legs. Then there are 4 legs of the couch as well that made it total of 20. If broken legs are of the men, then still the total will be 20 because the legs are still intact but 6 men left that means 12 legs are gone, if 3 legs break and 6 men leave. the number of legs remaining are 20–6*2–3=5.... so it's 5 I hope this helps! xoxo
To model time-variant data, one must create a new entity in an m:n relationship with the original entity, is a False statement.
- Like the majority of software engineering initiatives, the ER process begins with gathering user requirements. What information must be retained, what questions must be answered, and what business rules must be implemented (For instance, if the manager column in the DEPARTMENT table is the only column, we have simply committed to having one manager for each department.)
- The end result of the E-R modeling procedure is an E-R diagram that can be roughly mechanically transformed into a set of tables. Tables will represent both entities and relationships; entity tables frequently have a single primary key, but the primary key for relationship tables nearly invariably involves numerous characteristics.
