A massless string connects two pulley of masses ' ' and '
' respectively as shown in the figure.
The heavier pulley is fixed and free to rotate about its central axis while the other is free to rotate as well as translate. Find the acceleration of the lower pulley if the system was released from the rest. [Given, ]

View Full Answer(2)The following is the biochemical pathway for purple pigment production in flowers of sweet pea:
Colorless precursor 1 —- Allele A—-> Colorless precursor 2 —--- Allele B—---> Purple pigment
Recessive mutation of either gene A or B leads to the formation of white flowers. A cross is made between two parents with the genotype: AaBb × aabb. Considering that the two genes are not linked, the phenotypes of the expected progenies are:
9 purple : 7 white
3 white : 1 purple
1 purple : 1 white
9 purple : 6 light purple : 1 white
3(white):1(purple)
In case of 'duplicate recessive epistasis homozygous recessive gene masks the other gene i.e., aa is epistatic to A or a || bb is epistatic to B or b

The following system of linear equations
has
Option: 1 infinitely many solutions, satisfying
Option: 2 infinitely many solutions, satisfying
Option: 3 no solution
Option: 4 only the trivial solution.
System of Homogeneous linear equations -
If ? ≠ 0, then x= 0, y = 0, z = 0 is the only solution of the above system. This solution is also known as a trivial solution.
If ? = 0, at least one of x, y and z are non-zero. This solution is called a non-trivial solution.
Explanation: using equation (ii) and (iii), we have
This is the condition for a system have Non-trivial solution.
-
so infinite non-trivial solution exist
now equation (1) + 3 equation (3)
10x - 20z = 0
x = 2z
