Correct Option: C) Year 1
Body A having a mass of 2 kg and body B having a mass of 3 kg moving towards each other with velocities 4 m/s and 2 m/s, respectively, will collide and ____ in an elastic collision.
move in the direction of B
move in opposite directions
move in the direction of A
move perpendicular to the line of motion of both bodies
To determine the motion of the bodies after an elastic collision, we need to apply the principles of conservation of linear momentum and conservation of kinetic energy. For a one-dimensional elastic collision, we can use the formula for final velocities or calculate the total momentum before and after the collision.
Define the given parameters:
Apply the principle of conservation of linear momentum:
The total momentum before the collision is equal to the total momentum after the collision.
\[ m_A u_A + m_B u_B = m_A v_A + m_B v_B \] \[ (2 \text{ kg})(4 \text{ m/s}) + (3 \text{ kg})(-2 \text{ m/s}) = 2 v_A + 3 v_B \] \[ 8 - 6 = 2 v_A + 3 v_B \] \[ 2 = 2 v_A + 3 v_B \quad \text{(Equation 1)} \]Apply the principle of conservation of kinetic energy (for elastic collision):
For an elastic collision, the relative velocity of approach is equal to the relative velocity of separation.
\[ u_A - u_B = -(v_A - v_B) \] \[ u_A - u_B = v_B - v_A \] \[ 4 - (-2) = v_B - v_A \] \[ 6 = v_B - v_A \quad \text{(Equation 2)} \]From Equation 2, we can express \(v_B\) in terms of \(v_A\):
\[ v_B = 6 + v_A \]Solve the system of equations:
Substitute \(v_B = 6 + v_A\) into Equation 1:
\[ 2 = 2 v_A + 3 (6 + v_A) \] \[ 2 = 2 v_A + 18 + 3 v_A \] \[ 2 = 5 v_A + 18 \] \[ 5 v_A = 2 - 18 \] \[ 5 v_A = -16 \] \[ v_A = -\frac{16}{5} \text{ m/s} = -3.2 \text{ m/s} \]Now find \(v_B\):
\[ v_B = 6 + v_A = 6 + (-3.2) = 2.8 \text{ m/s} \]Interpret the results:
Since both velocities have changed sign, it means both bodies reverse their direction of motion. Therefore, they move in opposite directions relative to each other after the collision.
Both bodies reverse their directions of motion after the elastic collision. Body A moves with a velocity of \(-3.2 \text{ m/s}\) (opposite to its initial direction), and Body B moves with a velocity of \(2.8 \text{ m/s}\) (opposite to its initial direction). This means they move in opposite directions to each other.
A) move in the direction of B — This implies both bodies move in the direction of B's initial motion. Our calculations show that body B moves in the direction of A's initial motion, and body A moves in the direction of B's initial motion. So, they don't both move in the same direction.
C) move in the direction of A — This implies both bodies move in the direction of A's initial motion. Our calculations show that body A moves in the direction of B's initial motion, and body B moves in the direction of A's initial motion. So, they don't both move in the same direction.
D) move perpendicular to the line of motion of both bodies — This is incorrect because the collision is described as a one-dimensional collision (moving towards each other along a line). In such a collision, momentum perpendicular to the line of motion is conserved and typically zero, meaning the bodies continue to move along the same line, just possibly in reversed directions.
The question asks about the location where Prime Minister Narendra Modi and his Israeli counterpart Benjamin Netanyahu jointly inaugurated the iCreate centre in January 2018. This is a factual question related to a significant event in India's foreign relations and technological development.
C) Ahmedabad is the correct answer. The iCreate centre was jointly inaugurated by Prime Minister Narendra Modi and Israeli Prime Minister Benjamin Netanyahu in Ahmedabad, Gujarat, in January 2018.
The question asks to identify a cation from the given options. A cation is a positively charged ion, meaning it has lost one or more electrons. Anions, on the other hand, are negatively charged ions, having gained one or more electrons. We need to recall the chemical formula and charge of each given species.
Correct Option: C) Ammonium
This is a blood relation question. We need to establish the relationships between the individuals based on the given statements. We will use a systematic approach to deduce the relationship between V and F.
Correct Option: D) Sister-in-law
Since F and Z are brothers, and Z is married to V, V is F's sister-in-law (brother's wife).
The question asks to identify the host country/region for the 2018 Women's World T20 cricket tournament. This is a factual recall question related to major sporting events.
Correct Option: B) West Indies
The 2018 ICC Women's World Twenty20 was held in the West Indies from 9 to 24 November 2018. This was the sixth edition of the tournament.
The question asks to identify the river on which the Rana Pratap Sagar Dam is constructed. This requires knowledge of major dams and their associated rivers in India, a common topic in Indian competitive exams under Geography or General Knowledge.
Correct Option: D) The Rana Pratap Sagar Dam is indeed built on the Chambal River. It is part of a series of dams on the Chambal River, which also includes the Gandhi Sagar Dam, Jawahar Sagar Dam, and Kota Barrage. These dams are crucial for irrigation, power generation, and flood control in the region, particularly in Rajasthan and Madhya Pradesh.
