<span>coefficient
Let's look at the 3 possibilities and see what they are for </span>3H₂O₂ coefficient - This is used to indicate that multiple molecules are used for the formula. In 3H₂O₂ that indicates that we are talking about 3 molecules of H₂O₂ subscript - This is a small number set in a smaller font and placed low to the elements. It indicates the number of each type of atom in the compound. For the formula 3H₂O₂ there are 2 subscripts. Both of them being the number "2" set small and low just after the letters H and O. Those subscripts indicate that there are 2 hydrogen and 2 oxygen atoms per molecule.
element - This is the abbreviation for the elements used in the compound. In <span>3H₂O₂</span> there are 2 different elements. H to indicate hydrogen, and O to indicate oxygen.
Answer:
yea that is very true ◠﹏◠✿
Explanation:
Answer:
Special metal hangers or stirrups called joist hangers are used when joist must be flush with the bottom of the girder or beam.
Explanation:
- A joist hanger also known as a beam hanger is a mechanical device which is used to fasten joists and rafters.
- The rafters are the carried members to beams and headers are the carrying members.
Thus, special metal hangers or stirrups called joist hangers are used when joist must be flush with the bottom of the girder or beam.

It is possible to demonstrate that the maximum distance occurs when the angle at which the projectile is fired is
.
In fact, the laws of motions on both x- and y- directions are
From the second equation, we get the time t at which the projectile hits the ground, by requiring
, and we get:
And inserting this value into Sx(t), we find
And this value is maximum when
, so this is the angle at which the projectile reaches its maximum distance.
So now we can take again the law of motion on the x-axis
And by using
, we find the value of the initial velocity v0:
Answer:
I think they are both equal in strength but make sure from others
