The correct answer is: Option (D) 6 aluminum and 9 oxygen!
Explanation:
Since the one molecule of aluminium and oxygen is Al2O3 (Aluminum oxide). It has 3 oxygen atoms and 2 aluminium atoms. It find the atoms for the 3 molecules, multiply them with 3.
3 * 3 oxygen atoms = 9 oxygen
3 * 2 aluminum atoms = 6 aluminum ( Option D)
Answer:
Distance = 25000000 miles
Time = 50 hours
Explanation:
Venus is the closest planet to Earth. It is about 25 million miles away from Earth. Its precise distance depends on where both Venus and Earth are in their respective orbits
Given that
Speed V = 500000 mph
Distance d = 25 000,000 miles
Speed = distance/ time
Time = distance/speed
Time = 25000000/500000
Time = 50 hours
It will therefore take 50 hours to get to venus at that speed.
Answer:
C . All of the different types of electromagnetic waves
Answer:
F = 12.5N
Explanation:
Force (F) = Mass (m) x Acceleration (a)
F = ma
F = (2.5kg) x (5m/s^2)
F = 12.5N
