What is the study of waves called? Acoustics is the branch of physics concerned with the study of sound (mechanical waves in gases, liquids, and solids). A scientist who works in the field of acoustics is an acoustician. The application of acoustics in technology is called acoustical engineering. What does LW mean? Lucky Win What […]
What is the most likely reason that a hypothesis would be useful even?
What is the most likely reason that a hypothesis would be useful even? What is the most likely reason that a hypothesis would be useful even if experiments show that it is false? New hypotheses and experiments can be developed that better fit the observations made during the original experiments. Why is it smart to […]
Where an object is located in relation to another object?
Where an object is located in relation to another object? 7.1 An object is in motion if its position changes relative to another object. To decide if you are moving, you can use your chair as a reference point. A reference point is a place or object used for comparison to determine if something is […]
What are the two major types of seismic waves?
What are the two major types of seismic waves? There are two broad classes of seismic waves: body waves and surface waves. Body waves travel within the body of Earth. They include P, or primary, waves and S, or secondary, waves. What are the slowest seismic waves? The slowest waves, surface waves, arrive last. They […]
What are the three main characteristics of matter?
What are the three main characteristics of matter? Three States of Matter Matter can exist in one of three main states: solid, liquid, or gas. Solid matter is composed of tightly packed particles. Liquid matter is made of more loosely packed particles. Gaseous matter is composed of particles packed so loosely that it has neither […]
What two types of digestion occur in mouth?
What two types of digestion occur in mouth? Mechanical and Chemical Digestion There are two kinds of digestion: mechanical and chemical. Mechanical digestion involves physically breaking the food into smaller pieces. Mechanical digestion begins in the mouth as the food is chewed. What does the stomach do in the digestive system? Stomach. The stomach is […]
What happens if mass and velocity are doubled?
What happens if mass and velocity are doubled? Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum. What happens to the kinetic energy when the mass and velocity is […]
Does it mean if data are reproducible but not accurate?
Which of the following is not considered a region of the spinal cord?
Which of the following is not considered a region of the spinal cord? The d. pelvic region is not considered a region of the spinal cord. Which cells form myelin in the spinal cord? Schwann cells make myelin in the peripheral nervous system (PNS: nerves) and oligodendrocytes in the central nervous system (CNS: brain and […]
What happens if I never stretch?
What happens if I never stretch? Stretching keeps the muscles flexible, strong, and healthy, and we need that flexibility to maintain a range of motion in the joints. Without it, the muscles shorten and become tight. Then, when you call on the muscles for activity, they are weak and unable to extend all the way. […]
