A pattern in nature observed over and over
The answer is 52.79 m.
I used this formula to get the formula for Vy:
v^2=vi^2+2(a)(x)
And got
Vy=square root (19.6 h)
Then I used that and put it in this formula:
tan(65) =Vy/Vx
tan(65) = square root (19.6 h)/15.0
Then I rearranged it to:
h=[(15.0)(tan65)]/19.6
h=52.79 m
Answer:
1.17 x 10^2 L
Explanation:
We can find the volume of the gas by using the ideal gas law:

where we have:
is the pressure
V is the volume
n = 4.8 mol is the number of moles
R = 0.0821 L · atm/mol · K is the ideal gas constant
is the temperature
Solving the equation for V, we find the volume

The balanced combustion reaction
for butane is;
2C4H10 + 13O2 → 8CO2 + 10H2O
Molar mass of water = 18.02
g/mol
Molar mass of oxygen = 32 g/mol
2.46g H2O(1 mol H2O/18.02g)(13
mol O2/10 mol H2O)(32g O2/1 mol O2) = 5.68g O2
Answer: False.
Explanation: The Earth rotates once per day in direction from East to West. The rotation of the Earth daily is responsible for day and night experienced, the areas of the Earth facing the Sun experiences day time while the areas of the Earth away from the Sun in the Earth's shadow experiences night time.
While the revolution of the Earth around the gives rise to a year, as it takes 365 days for the Earth to go round the sun.
