A moving mass of 8 kg collides elastically with a stationary mass of 2 kg. If E be the initial kineticenergy of the mass, the kinetic energy left with it after collision will be(a) 0.80 E(b) 0.64 E(c) 0.36 E(d) 0.08 E |
|
Answer» answer : option (c) 0.36E explanation : Let v1' is final speed of mass 8kg and v2' is final speed of mass 2kg. INITIALLY, mass of 2kg is in rest so, v2 = 0 Initial kinetic energy = 1/2 (8kg)v1² or, E = 4v1² or, v1 = √E/2 using formula, v2' = 2m1/(M1 + m2)v1 - (m1 - m2)/(m1 + m2)v2 = 2 × 8 /(8 + 2) × √E/2 = 8√E/10 v1' = (m1 - m2)/(m1 + m2) v1 + 2m2/(m1 + m2) v2 = (8 - 2)/(8 + 2) × √E/2 + 0 = 3√E/10 now, final kinetic energy of mass 8kg, E' = 1/2 (8kg) × (3√E/10)² = 4 × 9E/100 = 36E/100 = 0.36 E hence, kinetic energy left with it after collision is 0.36E |

Independent day speech in our school of class 6 |
|
Answer» Answer: I offer you my greetings on the eve of our 73rd Independence Day. This is a happy and emotional day for all CHILDREN of Mother India, whether living at home or abroad. We remember with gratitude the countless freedom fighters and revolutionaries who struggled, strived and made heroic sacrifices to win us our freedom from colonial rule. We complete 72 years as a free nation at a very special juncture. In a few weeks from now, on October 2nd, we will CELEBRATE the 150th birth anniversary of the Father of our Nation, Mahatma Gandhi, the guiding light of our successful effort to liberate our nation and of our continuing effort to reform our society of all inequities. Contemporary India is very different from the India in which Mahatma Gandhi lived and worked. EVEN so, Gandhiji remains extremely relevant. In his advocacy of sustainability, ecological sensitivity and living in harmony with nature, he anticipated pressing challenges of our times. When we design and deliver welfare programmes for our disadvantaged fellow citizens and families, when we seek to harness the power of the sun as renewable energy, we put Gandhian philosophy into action. This year also marks the 550th birth anniversary of one of the greatest, wisest and most influential INDIANS of all time - Guru Nanak Devji. He was the founder of Sikhism, but the reverence and respect he commands go far beyond just our Sikh brothers and sisters. They extend to millions of others in India and across the world. My best wishes to them on this PIOUS occasion. |

A ball is thrown vertically upwards from the ground. It crosses a point at the height of 25 m twice at an interval of4s. The ball was thrown with the velocity of(1) 20 m/s(2) 25 m/s(3) 30 m/s(4) 35 m/s |
|
Answer» After reaching the maximum height , it falls for 2seconds to reach the 25 m height. Distance it has FALLEN is h = 0.5 gt^2 = 0.5*10* 4 =20 m. Maximum height is 25+20 = 45 m. Velocity at the bottom or the initial velocity is found from u^2 = 2gh = 2*10*45 =900 u = 30 m/s. Explanation: mark me BRAINLIEST if u WANT |

Explain critical angel and obtain an expression of it |
|
Answer» Answer: Critical angle for a boundary between 2 surfaces depends on the ratio of refractive INDICES of the media. Refractive index is inversely proportional to the VELOCITY of LIGHT in that medium. For finding the critical angle (x) we use the following equation: n₁∗sin(x)=n₂ n₁/n₂=v₂/v₁ (since they are inversely proportional) =>v₂∗sin(x)=v₁ =>x=sin⁻¹(v₁/v₂) This equation can be used to FIND the critical angle when a light incident from medium 1 ONTO the boundary between the medium 1 and 2.
