It's too much I don't understand.sorry
The work done by the electric force to move a 1 c charge from a to b is
<em>(the voltage at 'b' compared to 'a') volts .</em>
<em></em>
That's because "volt" means "Joule per Coulomb" .
Answer:
Part a)
k = 588.6 N/m
Part b)
v = 0.7 m/s
Explanation:
As we know that initially block is at rest
now if block is released from rest then it will go down by 10 cm and again comes to rest
so here we have
Part a)
Work done by gravity + work done by spring force = change in kinetic energy
Part b)
Now when spring is stretch by x = 5 cm then the speed of the block is given as
here we have
They are called beneficial mutations. They lead to new versions of proteins that help organisms adapt to changes in their environment. Beneficial mutations are essential for evolution to occur. They increase an organism's changes of surviving or reproducing, so they are likely to become more common over time.
Mutation is when there is a particular change in the bases of the DNA, this changes how enzymes and proteins work, and there may be a chance that this change will be helpful.
