Short Answer Questions 1 when do you say an object is in the state of motion?2. What is linear motion? How is it different from rotational motion? Explain with one example. 3. Differentiate between rotation of an object and the revolution of an object. 4. What is oscillatory motion? Give at least two applications of oscillatory motion. 5 Define random motion with the help of an example,6. How is the motion of a wheel of a moving bicycle and a mark on the blade pf a moving electric fan different? Explain |
|
Answer» position of one object change with RESPECT to another object with time then it is in motion or this phenomenon is called motion. For ex : a car is moving if its position is changing with respect to any other object say tree with the passage of time.2. LINEAR motion involves an object moving from one point to another in a straight line. Rotational motion involves an object rotating about an axis. – Examples include a merry-go-round, the rotating earth, a spinning skater, a top, and a turning wheel.3. When an object turns around an internal axis (LIKE the Earth turns around its axis) it is called a rotation. When an object CIRCLES an external axis (like the Earth circles the sun) it is called a revolution.4. Oscillation of simple pendulum. Vibrating strings of musical instruments is a mechanical example of oscillatory motion. Movement of spring.5.It is an unpredictable type of motion in which an object moves in any direction and the direction CHANGES continuously. Examples: The honey bee moves from one flower to another in search of nectar is also an example of random motion.6. The wheel of a moving bicycle depicts circular as well as rectilinear motion whereas a blade of a moving electric fan shows only circular motion. |

Answer» tion:Respiration: The process of RELEASING ENERGY by the oxidation of food is known as respiration. Respiration is of two types aerobic and anaerobic.Aerobic respiration:i. Respiration which takes place in the presence of oxygen is known as aerobic respiration.ii. During this process, food (GLUCOSE) is BROKEN down into carbon dioxide and water in the presence of oxygen.iii. Energy RELEASE in this process is stored in the form of adenosine triphosphate (ATP).Anaerobic respiration:i. Respiration which takes place in the absence of oxygen is known as anaerobic respiration.ii. In anaerobic respiration in microorganisms, glucose is broken down into ethanol and carbon dioxide with the release of energy.

The pines can be distinguished by their whorled clumps of needles that meet at a single point of attachment to the tree and their unique pine cones, which are the reproductive organs of the tree. As a general rule of thumb, pines tend to favor habitats with well-drained sandy soils.Pine HabitatPine habitats vary somewhat as you travel to different biological regions of the United States, but generally speaking pine trees can successfully compete with hardwoods when the soil conditions are mostly sandy and the land is well drained and not swampy. There are many different species of pine, so there is some variation across the United States in the HABITAT that a pine can occupy.
