Answer:
v =3.41 m/s
Explanation:
given,
mass of block 1 = 6 Kg
mass of another block 2 = 4 Kg
coefficient of friction = 0.3
Assuming 6 Kg block is attached to the spring of spring constant 350 N/m
and distance between the two block is equal to 0.5 m
using formula
U = 43.75 J
using conservation of energy
KE = U - f.d
where f is the frictional force acting
v =3.41 m/s

The true statement about ligand gated sodium ion channels in neurons are open in response to chemical messenger and hyperpolarize the membrane.
<h3>What are ligand gated sodium ion channels?</h3>
Ligand gated sodium ion channels are the channels present in the neurons. Ion moves through this channel inside the cell or outside the cell.
Thus, the correct option is a) Open in response to chemical messenger and depolarize the membrane.
