Explanation:
Water was on earth with the dinosaurs and almost at the very start.
Water starts anywhere from clouds to ponds
I choose ponds, water evaporates from the sun and moves its way through the air being collected into clouds in the atmosphere, clouds are evaporated water molecules, then the water combines to form rain wich then end up on a hill and travel back to a water source or goes into the ground and makes groundwater and if there is enough rain overtime will form a pond.
Answer:
The new volume of the balloon will be 6046.28 L
Explanation:
Initial pressure (P1) = 99 kpa
initial volume (V1) = 3000 L
Initial temperature = 39 C = 39 + 273 = 312 K
Final pressure (P2) = 45.5 kpa
Final temperature = 16 C = 16 +273 = 289K
Final volume = ????
To calculate the final volume using the general gas equation
P1 V1 / T1 = P2 V2 / T2
make V2 the subject of the formular
V2 = 99000 ×3000× 289 / 45500×312
V2 = 85833000 /14196
V2 = 6046.28 litres
Answer:
2-to produce copies of a DNA molecule
During a lifetime, a heart beats 3.1 x 10^9 times and it beats 91 times in one minute.
Thus, we can use cross multiplication to determine the number of minutes in the person's lifetime as follows:
number of minutes in person's lifetime = (3.1 x 10^9) / 91 = 34.0659 x 10^6 min
One year has 365.25 days (disregarding leap). Each day has 24 hours and each hour has 60 minutes.
Therefore,
one year = 365.25 x 24 x 60 = 525960 minutes
We can now use cross multiplication to determine the number of years of a person's lifetime as follows:
number of years = (34.0659 x 10^6 x 1) / 525960 = 64.76899 years.
