Answer:
1.28
Explanation:
If you want to find the m/s you would divide distance by time, so
45 divided by 35 would equal 1.28571429 and so on.
you can just write the three first numbers.
Answer:
Explanation:
As it mostly occurs on a surface where an ecosystem has previously existed. Primary succession only occurs on a surface where no ecosystem existed ever before!
Answer:
Approximately
, assuming that the acceleration of this ball is constant during the descent.
Explanation:
Assume that the acceleration of this ball,
, is constant during the entire descent.
Let
denote the displacement of this ball and let
denote the duration of the descent. The SUVAT equation
would apply.
Rearrange this equation to find an expression for the acceleration,
, of this ball:
.
Note that
and
in this question. Thus:
.
Let
denote the mass of this ball. By Newton's Second Law of Motion, if the acceleration of this ball is
, the net external force on this ball would be
.
Since
and
, the net external force on this ball would be:
.
Answer:
Facilitated diffusion.
Explanation:
Facilitated diffusion is the movement of molecules across a biological cell membrane by the use of a membrane protein.
It is a spontaneous passive movement and it can also be reffered to as FACILITATED TRANSPORT or PASSIVE-MEDIATED TRANSPORT.
Answer:
d' = d /2
Explanation:
Given that
Distance = d
Voltage =V
We know that energy in capacitor given as



If energy become double U' = 2 U then d'



2 d ' = d
d' = d /2
So the distance between plates will be half on initial distance.
