comparing the blank of an object with that of a liquid will tell you where or not the objects will float in that liquid
jenyasd209 [6]

Answer: Density

Explanation: Recall Archimedes Principle. There are two forces acting an object submerged in a liquid: the force of gravity and the  (opposite directed) force of buoyancy. The buoyancy is proportional to the mass of the liquid displaced by the submerged part of the object.

Density is the ratio of mass to volume. Therefore if the density of the submerged object is higher than that of the displaced liquid, the net force will point in the direction of the gravity (object will sink). In the opposite case, the net force will point in the direction of the buoyant force (upward) and the object will float.

Technician A says crimping solderless connections is the best method of splicing wires. Technician B says crimping should not be
algol13

Answer:

Technician b is correct.

Explanation:

Crimping cable allows a firm connection in mechanical terms and allows a low resistance path for the signal or the current flow, solder although it is better in terms of electrical conduction, can be impractical if the cable is subjected to excessive movement.

A crimped cable with excessive movement can also be easily broken at the ends, where it joins the part of the cable that is crimped, for this reason, a cable that is in excessive motion is recomended to be spliced ​​by joining cable with cable .

In order to decide which metod is better for splicing cables its necessary to evaluate each situation separatly.

Calculate the magnitude of the force, in newtons, exerted by a boxing glove on an opponent’s face, if the glove and face togethe
saul85 [17]

Answer:

5437.5 N

Explanation:

from the question we are given the following:

mass = 7.25 kg

initial speed (u) = 10.5 \frac{m}{s}

finial velocity (v) = 0

compression (s) = -7.35 cm = -0.0735 m (the negative sign is because the face is compressed, so there is a decrease)

we know that force = mass x acceleration,  

we have our mass but need to find the acceleration. we can get the acceleration by applying the formula below

v^{2} = u^{2} + 2as

therefore

0 = 10.5^{2} + (-2)× a × 0.0735[/tex]

a = \frac{10.5^{2} }{ 2 × 0.0735}[/tex]

a = 750

from F = m x a

force = 7.25 x 750 = 5437.5 N
