Meeting Bus: Car Acceleration and Kinetic Energy

The car accelerates from rest while the bus moves at a constant speed of 12 in parallel lanes.
To determine how long the car takes to meet the bus, the distance between them must be equalized.
Using the concept of displacement, the car's initial velocity of zero is considered, leading to the calculation of time.
The acceleration is found to be 1.2, resulting in a time of 20 seconds for the car to meet the bus.
Kinetic energy is discussed, highlighting that a lighter body will have greater kinetic energy if it stays longer.
Kirchhoff's law is mentioned in relation to heat absorption by dark bodies compared to light bodies.

"Mixing Substances, Density Equations, Energy Conservation"

When mixing two substances with volumes v and v, the mass in the resulting volume is calculated as patvi and total.
The density is determined by the volumes v and 2v, leading to the equation p1p = p2(p1 + p2).
The mass of both substances is equal, resulting in the equation p1v1 + p2v2 = 2m.
The volume in terms of density is found by equating p1v1 to m, and similarly for v2.
Adding the volumes of both substances gives the formula p1 + 1 = p2, resulting in 2p1p2/(p1 + p2) = 3.
Calculations lead to the values of p1 and p2 as 8 and 4, respectively, resulting in a ratio of 6:12.
