Answer:
So the mass of the second object M will be 1.951 kg
Explanation:
We have given mass of the first object and its velocity
Mass of the second object it is at rest so its velocity
From conservation of momentum we know that
Initial momentum = final momentum
So
M = 1.951 kg
To minimize neutron leakage from a reactor, the ratio of the surface area to the volume should be a minimum. For a given volume V , ratio for (c) a parallelepiped of dimensions × 2 a will be
What will be the ratio of surface area and the volume of the parallelepiped
We will proceed by stating the equations of the surface area and the volume of each shape, and then identifying each of the surface area and the volume, we will take their ratios, and as it is asking for the shape which has the minimum surface area to volume ratio, therefore at some given volume, .
The parallelepiped whose dimension is given as
the surface area and the volume is given respectively by:
Let the volume be equal to the constant c, we get:
Hence the ratio is given by:
Calculating the constants, by substituting the value of in (3), we get:
