Answer:
2.5
That is my guess sorry if i get it wrong.
That would be false
Explanation:
Explanation:
Molecular mass is defined as the sum of atomic masses of all the atoms present in a given compound.
For example, molecular mass of is as follows.
=
=
= (12 + 4) g/mol
= 16 g/mol
Hence, the molecular mass of is 16 g/mol.
Therefore, we can conclude that the sum of the atomic masses of all the atoms in a formula for a covalent compound is the molecular mass.
Answer:
D, I think.
Explanation:
I had a quiz in Plate Tectonics and there was 2 questions that are related to this, but not the exact question.
Which material rises from cracks in oceanic crust
-molten rock
Which is the first step in the seafloor spreading process?
-a crack forms in oceanic crust.
those are all right btw, so you can decide if the answer I told you is right or not.
Answer:
<em>The person needs to apply 25 N to balance the seesaw</em>
Explanation:
<u>Moment</u>
The moment of a force is a measure of its tendency to cause a body to rotate about a specific point or axis.
The moment M of a force F located at a distance x from the axis of rotation is calculated as follows:
M = F.x
The image shows a moment of M=100 N.m is needed to be applied to balance the seesaw. It can also be noted that the distance to the pivot is x=4 m
To calculate the force needed to balance the seesaw, we solve for F:
F = 25 N
The person needs to apply 25 N to balance the seesaw
