I am thanking your answers and giving you brainliest just becoz I thank to all answers which are on my question and I marked your answers brainliest jst becoZ they were helpful ...I hope you would have got your answer.What is retardation? |
|
Answer» Retardation is nothing but a negative acceleration. The VELOCITY of the body may either INCREASE or decrease. The change in velocity is KNOWN as acceleration. ... Retardation is acceleration with a negative sign. Or the negative value of acceleration shows that the velocity of a body is decreasing. |

Two objects of masses 100 g and 200 g are moving along the sameline and direction with velocities of 2 m/ s and 1 m /s, respectively.They collide and after the collision, the first object moves at a velocityof 1.67 m /s. Determine the velocity of the second object. |
|
Answer» Answer: heyyyy We can SOLVE the GIVEN problem by using the law of conservation of momentum. Given Mass of one of the OBJECTS (m₁) = 100 g = 0.1 kg Mass of the other object (m₂) = 200 g = 0.2 kg Velocity of m₁ after collision (v3) = 1.67 m/s Velocity of m₁ before collision (v₁) = 2 m/s Velocity of m2 before collision (v₂) = 1 m/s Find out Velocity of m2 after collision=V4 Solution According to the law of conservation of momentum: TOTAL momentum before collision = Total momentum after collision Therefore, m₁v₁ + m₂V₂ = ₁V3 + m₂V4 On sustitututing the known and given values we get 2(0.1) +1(0.2) = 1.67(0.1) + v4× (0.2) 0.4 0.167 + 0.2 × V4 V4= 1.165 m/s Answer Hence, the velocity of the second object becomes 1.165 m/s after the collision. i hope it helps mark me as brainliest please |

An object of mass 100 kg is accelerated uniformly from avelocity of 5 m /s to 8 m /s in 6 s. Calculate the initial and finalmomentum of the object. Also, find the magnitude of the forceexerted on the object. |
|
Answer» Initial velocity of the object (u) = 5 m/s Final velocity of the object (v) = 8 m/s Mass of the object (m) = 100 kg Time take by the object to accelerate (t) = 6 s Initial momentum = mu = 100 × 5 ⇒ mu = 500 kg m/s Final momentum = mv = 100 × 8 ⇒ mv = 800 kg m/s Let us calculate the Force exerted on the object (F) F = (mv – mu) / t F = (800 – 500)/6 F = 300 / 6 F = 50 N Initial momentum of the object is 500 kg m sˆ1. Final momentum of the object is 800 kg m sˆ1. Force exerted on the object is 50 N. please mark me brain mark LIST |

Explain the process by which a permanent magnet can magnetise an ordinary piece of iron. Class 6 |
|
Answer» Answer: This METHOD involves simply placing the magnetic material (SOFT iron) close to a strong magnet WITHOUT touching. The soft iron BAR becomes an induced magnet with the end NEARER the magnet having opposite polarity to that of the magnet. Hence, the soft iron bar is attracted and attached to the permanent magnet. |
