What is antimatter and tell it's composition |
|
Answer» Answer: Antimatter, substance composed of subatomic particles that have the mass, electric charge, and MAGNETIC moment of the electrons, protons, and neutrons of ordinary MATTER but for which the electric charge and magnetic moment are opposite in sign. Explanation: In THEORY, a particle and its anti-particle (for EXAMPLE, a proton and an antiproton) have the same mass, but opposite electric charge and other differences in quantum numbers. For example, a proton has positive charge while an antiproton has negative charge. |

1)What is the angular momentum??2) Break this code 109251 9 1215225 251521 |
|
Answer» Explanation: The ANGULAR MOMENTUM of a rigid object is DEFINED as the PRODUCT of the moment of inertia and the angular velocity. It is analogous to linear momentum and is subject to the FUNDAMENTAL constraints of the conservation of angular momentum principle if there is no external torque on the object. |

What is momentum meaning and give a example of a equation including momentum? |
|
Answer» MOMENTUM the property of a moving OBJECT to continue moving. For an object moving in linear motion, the momentum is the mass*velocity (linear momentum); thus, a SLOWLY moving, very massive body and a rapidly moving, light body can have the same momentum. Momentum is a vector quantity The standard unit of momentum magnitude is the kilogram-meter per second (kg·m/s or kg·m·s-1 ). ... Momentum, like velocity, is relative. hope this helps pls MARK as brainliest |

A train travels the first 30 km of 120 kilometre track with a uniform speed of 30 kilometre per hour what should be the speed of train to cover the remaining distance of the track so that its average speed is 60 kilometre per hour for the entire trip .plzz helpno spam |
Answer» follow meeDISTANCE d1 = 30 km, v1 = 30 kmph => time taken = t1 = d1/v1 = 1 hour So distance remaining = d2 = 120 - d1 = 90 km let speed to cover distance d2 = v2 kmph => time taken = d2/v2 = 90/v2 hours average speed = total distance / total DURATION of time 60 kmph = 120 km / [1 hour + 90 / v2 hours] => 1 = 2 / [ 1 + 90 / v2 ] => v2 = 90 kmph ==================================== another way: as the total distance = 120 km average speed = 60 kmph => total time duration = 120 / 60 = 2 hours
time taken for the FIRST 30 km = 30 km /30 kmph = 1 hours Hence, time remaining to cover the remaining 90 km = 2 HRS - 1 hrs = 1 hour => speed during 90 km = 90 kmph |

Write the third equation of motion and it's solutions |
|
Answer» Explanation: The TOTAL distance travelled, S = Area of trapezium OABC. So, S= 1/2(SumofParallelSides)×Height S=(OA+CB)×OC Since, OA = u, CB = v, and OC = t The above equation becomes S= 1/2(u+v)×t Now, since t = (v – u)/ a The above equation can be WRITTEN as: S= 1/2(u+v)×(v-u)/a Rearranging the equation, we get S= 1/2(v+u)×(v-u)/a S = (v2-u2)/2a Third equation of motion is obtained by solving the above equation: v2 = u2+2aS Derivation of Third Equation of Motion by Calculus METHOD It is known that, Derivation Of Equation Of Motion These were the detailed derivations for EQUATIONS of motion in the graphical method, algebraic method and calculus method. |
