D. compressors because it decreases density and compresses it. that makes it prevent energy transfer
A.)
300 ml * 8 = 2.4 gallons a day.
now time to see how much a year..
2.4 * 365 = 876 liters
B.)
one liter = 2.2 pounds
876 x 2.2 = 1927.2 pounds
Answers:
<u>A.) 2.4 * 365 = 876 liters</u>
<u>B.) 876 x 2.2 = 1927.2 pounds</u>
Answer:
932.44 km/s
Explanation:
Given that:
The work function of the magnesium = 2.3 eV
Energy in eV can be converted to energy in J as:
1 eV = 1.6022 × 10⁻¹⁹ J
So, work function =
Using the equation for photoelectric effect as:
Also,
Applying the equation as:
Where,
h is Plank's constant having value
c is the speed of light having value
m is the mass of electron having value
is the wavelength of the light being bombarded
v is the velocity of electron
Given,
Thus, applying values as:
v = 9.3244 × 10⁵ m/s
Also, 1 m = 0.001 km
<u>So, v = 932.44 km/s</u>

Answer:
20 mole of oxygen
Explanation:
1 mole of proprane reacts with 5 moles of oxygen so 4 time 5 equals 20
