For this case, the first thing you should do is write the kinematic motion equation of the block.
We have then:
vf = vo + a * t
Where,
vf: Final speed.
vo: Initial speed.
a: acceleration.
t: time.
Substituting the values:
(16) = (0) + a * (16)
Clearing the acceleration:
a = 16/16 = 1m / s ^ 2
Note: the other data for this case are not used in this problem.
answer:
The acceleration of the box is 1m / s ^ 2
Answer:
columns are converted into rows , and rows are converted into columns
Answer:
A. The volume of the object
Explanation:
First of all, it can only PROBABLY be A or D
But why is it only A?
- Mass = The amount of matter in an object (nothing related here)
- Volume = How much space is the object taking (super related here)
It's VOLUME here and not MASS here because:
- It it would be Mass, then the object size could be anything, but the liquid wouldn't move as much higher.
- But because it is Volume, it is taking space, which makes the liquid move
- If the Mass would be the answer, then it would be totally not related, because mass isn't related over here, it matters about size.
<h2>
Hence, A. The volume of the object </h2>
is your answer!!!!
Answer:
0.650
Explanation:
Move the decimal point three times to the left.
A. 2 C₂ H₆ + 7 O₂ → 4 C O₂ + 6 H₂ O
according to law of conservation of mass , the total mass of reactants side must be same as the total mass of product side. so we need to check if each atom in the equation has same number on both side of the equation or not.
in this equation , we have
4 atoms of carbon left and 4 atoms of carbon on right
12 atoms of hydrogen on left and 12 atoms of hydrogen on right
14 atoms of oxygen on left and 14 atoms of oxygen on right
