Answer:

The Mach number at the inlet is 0.14

Explanation:

Mach number = v/a

v = 75 m/s

a = sqrt(kRT)

k = 1.288

R = 0.1889 kJ/kg.K = 0.1889×1000 = 188.9 J/kg. K

T = 1200 K

a = sqrt(1.288×188.9×1200) = sqrt(291963.84) = 540.34 m/s

Mach number = 75m/s ÷ 540.34m/s = 0.14

A 10-ft moving truck has a volume capacity of 402 cubic feet, which is equivalent to 1.138 x 10⁷ milliliters. What mass of silve
steposvetlana [31]

Answer:

The mass of silver is 1.19\times 10^{14}\ Mg

Explanation:

Given that,

The volume of the truck is 402 cubic feet or 1.138 x 10⁷ mm.

The density of silver is 10.49 g/mL.

We need to find the mass of silver that will fit in this moving truck. Density equals mass divided by volume. So,

d=\dfrac{m}{V}\\\\\text{where m is mass}\\\\m=d\times V\\\\m=10.49\ g/mL\times 1.138 \times 10^7\ mL\\\\m=119376200\ g

1 gram = 10⁻⁶ Megagram

119376200=1.19\times 10^{14}\ Mg

Hence, the mass of silver is 1.19\times 10^{14}\ Mg

Molar mass of c16h19n305s
Masja [62]

Answer:

365.212

Explanation:

According to the given situation, the calculation of molar mass is shown below:-

Data provided

c_{16}\ h_{19}\ n_3\ o_5\ S

Molar mass = 16 × 12 + 19 × 1.008 + 3 × 14 + 5 × 16 + 32.06

= 192 + 19.152 + 42 + 80 + 32.06

Molar mass = 365.212

Therefore for determining the molar mass we simply solve the above equation.

So, the correct answer is 365.212

Which atomic model shows the atom as a positively charged sphere with negatively charged electrons spread throughout
tankabanditka [31]

Answer:

B) Thomson's Model

Explanation:

Dalton's Model simply consisted of small spheres that represented atoms, and Bohr's model had a nucleus in the center with electrons orbiting in strict orbits, not randomly spread throughout. Thomson's plum pudding model, however, had an overall positively charged atom with many electrons spread throughout. If you search up "Plum Pudding Model" you can visually understand this.
