Earth's atmosphere is a <em>mixture</em> of gases that have
not reacted to become chemical compounds.
Answer:
Explanation:
Let the tension in horizontal rope be T₁ and in the other rope be T₂ which is making angle of 51.3⁰
The vertical component of tension T₂ will balance the weight .
= T₂ cos 51.3 = 2.9 x 9.8
T₂ = 2.9 x 9.8 / cos 51.3
= 28.42 / .625
= 45.47 N
The horizontal component of T₂ will balance T₁
T₂ sin 51.3 = T₁
45.47 sin 51.3 = T₁
T₁ = 35.48 N .
Answer:
The maximum mass is 
Explanation:
The wavelength of the electron can be determined by means of the De Broglie equation.
(1)
Where h is the Planck's constant and p is the momentum.
(2)
Where m is the mass and v is the velocity.
Before using equation 2 it is necessary to express the wavelength from femtometers to meters.
--
Finally, equation 2 can be used.
But 
Hence, the maximum mass is 
Answer;
-Science
Explanation;
-Science is a process that involves the collection of information and ideas supported by evidence. Pseudoscience on the other hand, is a process that involves the collection of information and ideas supported by belief or opinion.
-Science is a systematic and logical approach to discovering how things in the universe work. It is also the body of knowledge accumulated through the discoveries about all the things in the universe. Science is based on fact, not opinion or preferences. The process of science is designed to challenge ideas through research. It aims for measurable results through testing and analysis.
