Answer:
Given its huge success in describing the natural world for the past 150 years, the theory of evolution is remarkably misunderstood. In a recent episode of the Australian series of “I’m a Celebrity Get Me Out of Here”, former cricket star Shane Warne questioned the theory – asking “if humans evolved from monkeys, why haven’t today’s monkeys evolved”?
Similarly, a head teacher from a primary school in the UK recently stated that evolution is a theory rather than a fact. This is despite the fact that children in the UK start learning about evolution in Year 6 (ten to 11-year-olds), and have further lessons throughout high school. While the theory of evolution is well accepted in the UK compared with the rest of the world, a survey in 2005 indicated that more than 20% of the country’s population was not sure about it, or did not accept it.
Explanation:
Answer:
The new volume of a gas at 750 mmhg and with a volume of 2. 00 l when allowed to change its volume at constant temperature until the pressure is 600 mmhg is 2.5 Liters.
Explanation:
Boyle's law states that the pressure of a given amount of gas is inversely proportional to it's volume at constant temperature. It is written as;
P ∝ V
P V = K
P1 V1 = P2 V2
Parameters :
P1 = Initial pressure of the gas = 750 mmHg
V1 = Initial pressure of the gas = 2. 00 Liters
P2 = Final pressure of the gas = 600 mmHg
V2 = Fimal volume of the gas = ? Liters
Calculations :
V2 = P1 V1 ÷ P2
V2= 750 × 2. 00 ÷ 600
V2 = 1500 ÷ 600
V2 = 2.5 Liters.
Therefore, the new volume of the gas is 2. 5 Liters.
Molar mass is the mass of one stable molecule of a compound, that cannot join with another molecule of the same kind to form a new one, while an empirical formula is the molecular formula in its simplest form. E.g. empirical formula of ethene is CH2while its molecular formula is C2H4.
To determine the number of cups of milk, we first calculate for the volume of the milk needed. Then, we use a conversion factor for the volume from cubic centimeter to cups. From literature, 1 cubic centimeter is equal to 0.0042 cup. We do as follows:
Volume of milk = ( 2.50 kg ) ( 1000 g / 1 kg ) / 1.03 g /cm^3 = 2427.18 cm^3
cups of milk = 2427.18 cm^3 ( 0.0042 cup / 1 cm^3 ) = 10.19 cups
The length is 1.36 feet and the breadth is 17.647 feet of the plate, if friction drag is 0.3 lbf.
T = 20°C = 293 K
P = 1 atm = 101.325kP
P = ρRT
ρ = 1.205 kg/m³
Total drag = C∝ * (1/2 .ρ . A . V²)
0.3 lbf = C∝ * 1/2 * 1.205 * 4.645 * (15.24)²
C∝ = 2.05338 * 10 ⁻³
Now,
C∝ = 1.328 / √Re
2.05338 * 10 ⁻³ = 1.328 / √Re
∴ Re = 418267.61
∴ ρ. v. l/μ = 418267.61
1.205 * 15.24 *L/18.207 * 10⁻⁶ = 418267.61
Length = 0.4147 m = 1.36 foot
L * B = 24 ft²
1.36 * B = 24
∴ breadth = 17.647
Hence, Length is 1.36 feet and the breadth is 17.647 foot.
