Explain the concept of pitch of sound |
| Answer» The pitch of a sound can simply be thought of as a measure of the sound\'s frequency. For example when an instrument plays different notes they are more accurately different pitches. These pitch differences are actually just the ear and brain\'s perception of the instrument emitting different frequencies.When there is a high frequency, the ear interprets the sound as a higher pitch, and when the frequency is low, the ear hears a low pitch. Pitch has been standardized and uses "cents" as a unit of measurement. | |

Kepler\'s 2nd law |
|
Answer» Planets cover equally area in equal time interval ✋? The radius vector drawon from the sum to a planet sweeps but the equal area equal universal of time Kepler\'s second law of planetary motion describes the speed of a planet traveling in an elliptical orbit around the sun. It states that a line between the sun and the planet sweeps equal areas in equal times. |

Define centre of mass of two particle system |
| Answer» The centre of mass is an imaginary point where one can assume the entire mass of the given system or object to be positioned.Consider a system consisting of two point masses m1 and m2, whose position vectors at a time t with reference to the origin O of the inertial frame are respectively.This can be written mathematically asSimilarly, for the point mass m2 ,According to the Newton\'s second law of motion, the equation of motion of point mass m1 isSimilarly, for the second particleAdding equations (3) and (4), we getwhich implies,From (1) and (2),According to Newton\'s third law,From equation (5),Where m = m1 + m2, that is the mass of a hypothetical object. Its position at any time is given by position vector such that,This is nothing but the position vectorand is called the centre of the mass of the two-particle system.It is the point where the total external force is supposed to act.For a two-particle system, the centre of mass lies between the two particles and on the line joining them.If i.e., the mid-point of the line joining the masses.\xa0 | |

What is horizontal projectiles? |
|
Answer» Projectiles motion in horizontal direction A horizontally thrown ball and a bullet fired from a rifle held horizontally are the examples of projectiles in the horizontal direction. For this type of projection there is an initial velocity u only in the horizontal or x-direction. But there is no initial velocity in the vertical or y-direction.However, there is acceleration in the downward direction due to gravity. Since there is no acceleration or force in the x-direction after it is projected, the projectile moves in this direction with a constant speed (u).As the object moves horizontally, it also falls in the downward direction due to gravity. In the downward direction, the motion is the same as that of a dropped object. |
