The answer would be C. 5m
This is because to find d, you would need to divide W (125 J) by F (25 N).
Hope this helps!
4 atoms
Explanation:
On the product side, we expect to find 4 atoms of the product.
An atom is the smallest indivisible particle that takes part in a chemical reaction.
An element is a distinct substance that cannot be split-up into simpler substances. Such substances consist of only one kind of atom.
In this reaction we have:
2 elements: Mg O
on the reactant side:
We have two moles of Mg: 2 atoms of Mg
1 mole of oxygen gas: 2 atoms of O
total atoms: 4 atoms
According to the law of conservation of matter "in a chemical reaction, matter is neither created nor destroyed".
We expect to find 4 atoms of products which is MgO on the product side.
2Mg + O₂ → 2MgO + heat

Answer:
I believe the answer is B.
Answer:
0.195 m
Explanation:
Speed is distance moved per unit time, expressed as s=d/t and making d the subject of the formula then d=st
Where d is distance/depth moved, s is rhe speed of waves and t is time in seconds.
Substituting s with 1300 m/s and t with 0.00015 s then the depth of metal segment will be
D=1300*0.00015=0.195 m
Therefore, the depth is equivalent to 0.195 m
Answer:
i - component of V is zero for any value of t i-e no motion in this direction
Explanation:
Since
r= i+3
j+t k
==> V = 
=
=
and acceleration is given by taking derivative of velocity w.r.t t
==> a= 
=
=
so, V=0i+6tj+k
and
a = 0i+6j+k
i - component of V is zero for any value of t i-e no motion in this direction
