Answer:

A. a concentric contraction because muscles cause the elbow joint and arm to move.

Explanation:

Contraction is the phenomenon in which the muscles of our body get activated by the tension produced. When the muscle of our body shortens, caused by the tension applied on our muscle is called concentric contraction. The force produced by the muscle as it shortens bring the cup near our body. There it is an example of concentric contraction.

You would expect a phosphorous-chlorine bond to be
zlopas [31]

Answer: option 4. polar, with the chlorine end having a partial negative charge.


Explanation:


1) A polar bond is a covalent bond in which the electrons are pulled more strongly by one of the atoms and then they are not evely distributed between the two linked atoms.


2) That happens when the two atoms have diferent electronegativities.


3) As the per periodic table trend of the electronegativity, you can predict that the electronetativity of Cl is higher than that of P.


In fact, in a table of electronegativities you can find that the electronegativity of Cl is 3.16 while the electronegativity of P is 2.19.


This is a 3.16 - 2.19 = 0.97 difference.


As explained, that difference means that Cl will pull the electrons more strongly resulting if a partial negative charge on Cl and a partial positive charge on P, i.e. a polar bond.

A block of metal has a mass of 51.11 g and displaces 71.46 ml of water. Calculate the density of the metal in g/ml.
Damm [24]

Answer:

The answer is

<h2>0.07 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass of metal = 5.11 g

volume = 71.46 mL

The density of the metal is

density =  \frac{5.11}{71.46}  \\  = 0.071508536...

We have the final answer as

<h3>0.07 g/mL</h3>

Hope this helps you

Why is a liquid able to flow
luda_lava [24]
Since the particles can move, the liquid<span> can flow</span> <span>and take the shape of its container. Some insects, such as pond-skaters, are able</span><span> to walk on water without sinking. This is because the forces of attraction between the water particles pull the particles at the surface together.</span>
