This problem is to let you practice using Newton's second law of motion:
Force = (mass) x (acceleration)
-- The airplane's mass when it takes off (before it burns any of its load of fuel) is 320,000 kg.
-- The force available is (240,000 N/per engine) x (4 engines) = 960,000 N.
-- Now you know ' F ' and ' mass '. Use Newton's second law of motion to calculate the plane's acceleration.
Steel is more dense because it’s heavy while water is light
Answer:
Explanation:
You can calculate the total electric charge that passes through the conductor as 
. It means that the number of electron that passes through the conductor is:
Answer: A
Explanation:
honestly, it sounded the best
isotopes are the same element, but have different numbers of neutrons (but still have the same number of electrons and protons), hence have a different mass number.
