Answer:
Lessens
Explanation:
The performance of an engine at high altitudes is lower due to the decreasing density of air with elevation, such that at high altitude, the density is much less and a given quantity of oxygen occupies much more space at high altitudes, and the oxygen content in the air drawn in is lesser at high altitude, and the combustion power is much lesser at high altitudes when the engine speed is high up to about 4000 rpm.
Answer:
Zero, the support force and gravitational force together equal a zero net force
Explanation:
Answer: Option (C) is the correct answer.
Explanation:
An atom consists of three subatomic particles which are protons, neutrons and electrons.
The protons and neutrons are present inside the nucleus. Whereas electrons revolve around the nucleus.
Whenever there is a bond formed by loss, gain or sharing between any two atoms then it is due to the electrons.
Hence, we can conclude that atoms may be bonded together by losing, gaining, or sharing electrons.
