Explanation:
Mg-2+C+4>Mg2C.
Here you divide the four by the two and transfer the two toMg. In reactions like this oxidation numbers are exchanged.
The net force on the object is 5 N.
Explanation:
We can calculate the net force on the object by using Newton's second law of motion:
where
F is the net force on an object
m is the mass of the object
a is its acceleration
For the object in this problem, we have
m = 1 kg is its mass
is its acceleration
Substituting into the equation, we find the net force:

Answer:
It is just a theory that multi verse exists. Researchers have found tracers of mirror particles which could only be from other universe.
Explanation:
Its said above.
It’s definitely the 3rd one
Answer:
P + C = W if in equilibrium?
P + C - W = 0; P + C = W
Explanation:
Action and reaction are equal and opposite according to newton's third law of motion. a force is that which tends to change a body's state of rest or uniform motion in a straight line, recall
P is the upward force the person exerts on the crate,
C is the vertical contact force exerted on the crate by the floor,
W is the weight of the crate
let the sum of upward forces be on the left hand side of the equation and the sum of downward forces on the right hand side.
P+C=W
P+C-W=0 if they are in equilibrium
the forces are related by the above.
