What is a physical system in science? In physics, a physical system is a portion of the physical universe chosen for analysis. Everything outside the system is known as the environment. For example, the water in a lake, the water in half of a lake, or an individual molecule of water in the lake can […]
What are the signs of a bad throttle body position sensor?
What are the signs of a bad throttle body position sensor? Symptoms of a Bad or Failing Throttle Position Sensor Car won’t accelerate, lacks power when accelerating, or accelerates itself. Engine won’t idle smoothly, idles too slowly, or stalls. Car accelerates, but won’t exceed a relatively low speed, or shift up. Check Engine Light comes […]

How do you check your trachea?
How do you check your trachea? Bronchoscopy — A rigid or flexible tube that has a tiny camera on the tip (called a bronchoscope) is inserted through the nose or mouth into the airway to examine the trachea and bronchi. Biopsy — A small sample of tracheal or bronchial tissue is removed through a bronchoscope. […]
Can you hear cosmic background radiation?
Can you hear cosmic background radiation? Yes, you can indeed hear it, and you do so by essentially the same technique you use to listen to an ordinary (non-digital!) How is CMB detected? The Cosmic Microwave Background, or CMB, is radiation that fills the universe and can be detected in every direction. Microwaves are invisible […]
How do you solve non-homogeneous linear recurrence relations?
How do you solve non-homogeneous linear recurrence relations? Example Let a non-homogeneous recurrence relation be Fn=AFn–1+BFn−2+f(n) with characteristic roots x1=2 and x2=5. Solve the recurrence relation Fn=3Fn−1+10Fn−2+7.5n where F0=4 and F1=3. This is a linear non-homogeneous relation, where the associated homogeneous equation is Fn=3Fn−1+10Fn−2 and f(n)=7.5n. x2−3x−10=0. What is a linear homogeneous recurrence relation? We […]
What makes a resonance structure more stable?
What makes a resonance structure more stable? The most stable resonance structure will have a full octet on every atom. 2. The most stable resonance structure will have the smallest possible number of charges. The most stable resonance structure will have negative charges on the most electronegative atoms and positive charges on the least electronegative […]
What is the bond angle of h2te?
Which of the following best describes a water molecule?
Which of the following best describes a water molecule? A water molecule consists of one oxygen atom bonded to two hydrogen atoms by covalent bonds. Since oxygen is more electronegative as compared to hydrogen atoms, the shared electrons are attracted towards the oxygen atom. What forms a hydrogen bond? Hydrogen bonding is a special type […]
