Answer:
D. are made of cell
Explanation:
first , cell simply means the basic and structural unit of life ......All living organisms have cells
It could be Unicellular(amoeba), colonial form ( volvox) , filamentous form(spirogyra) or multicellular .......
Answer:
time is 3333.33 min or 55.55 hr
Explanation:
given data
reactor operating = 1 MW
negative reactivity = $5
power = 1 miliwatt
to find out
how long does it take
solution
we know here power coefficient that is
power coefficient = 
power coefficient = 1
so time required to reach power is
power = reactivity × time / power coefficient + reactor operating
1 × 
= -5 t / 1 + 1 × 
5t = -
t = 199999.99 sec
so time is 3333.33 min or 55.55 hr
To make a educational guess based on the your observations
Answer:
C) True. At maximum displacement, its instantaneous velocity is zero.
Explanation:
The simple harmonic movement is given by
x = A cos wt
Speed
v = - A w sin wt
At the point of maximum displacement x = A
A = A cos wt
cos wt = 1
wt = 0
We replace the speed
v = -Aw sin 0 = A w
Speed is maximum
Let's review the claims
A) False. Speed is zero
B) False. It can be determined
C) True. Agree with our result
D) False. When one is maximum the other is minimum
I think is A or B it depends on like what the trying to answer
