Answer:
Explanation:
The force of gravity will cause your vehicle to speed up when going downhill, and slow down when going uphill. ... The factors that affect your energy of motion are speed and weight.
Answer:
19063.6051 g
Explanation:
Pressure = Atmospheric pressure + Gauge Pressure
Atmospheric pressure = 97 kPa
Gauge pressure = 500 kPa
Total pressure = 500 + 97 kPa = 597 kPa
Also, P (kPa) = 1/101.325 P(atm)
Pressure = 5.89193 atm
Volume = 2.5 m³ = 2500 L ( As m³ = 1000 L)
Temperature = 28 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (28.2 + 273.15) K = 301.15 K
Using ideal gas equation as:
PV=nRT
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L.atm/K.mol
Applying the equation as:
5.89193 atm × 2500 L = n × 0.0821 L.atm/K.mol × 301.15 K
⇒n = 595.76 moles
Molar mass of oxygen gas = 31.9988 g/mol
Mass = Moles * Molar mass = 595.76 * 31.9988 g = 19063.6051 g
Answer:
D. A and B
Explanation:
1. The method Console.Write() is an overloaded method in a language like C#.
One of its variations could be as follows;
<em>Console.Write(String format, Object a, Object b).</em>
This contains three parameters and will write the text representation of the specified objects to the standard output stream using the information specified by the format specifier. Parameter 1 is <em>format</em> which is a composite format string representing the format specifier. Parameter 2 is <em>a</em>, which is the first object to be written using <em>format. </em>Parameter 3 is b, which is the second object to be written using <em>format</em>.
2. The method Console.WriteLine() has the same characteristics as Console.Write() above, except that it writes the text representation of the specified objects, followed by current line terminator then to the standard output stream using the information specified by the format specifier.
3. Console.WriteFormat() does not exist, at least not in C# or .NET
Therefore, Console.Write() and Console.WriteLine() have the capacity to display formatted data.

1 liter = .264 gallon
1 km = .621 mile
this means that 58.3km/L is equal to 137.13mpg
so
500/137.13 = 3.65 gallons of gas
3.65 x 3.5 = $12.78
Answer:
the correct answer is option B. W
