Answer:

<h2>The volume displaced is 6.2 cubic meters.</h2>

Explanation:

This question is incomplete.

However, we can find the volume displaced using the given mass and the density of brass.

m=54g\\\rho=8.73 g/cm^{3}

So, to find the volume, we use the definition of density, which is

\rho = \frac{m}{V}

Where \rho is density, m is mass and V is volume.

Replacing all values, we have

\rho = \frac{m}{V}\\V=\frac{m}{\rho}=\frac{54g}{8.73g/cm^{3} } =6.2cm^{3}

Therefore, the volume displaced is 6.2 cubic meters.

List the three components of effective communication and give an example of each
Marrrta [24]

Answer:

The three components of effective communication are:

  1. Sending Communication
  2. Receiving Communication
  3. Feedback

Explanation:

<h3>1) Sending Communication</h3>

One should think about what he is going to say, structure his message and focus clearly on a the purpose of sending a message. For example if an employer wants to communicate an employee to improve his performance, he should focus hid communication on the results rather than on his failures.

<h3 /><h3>2) Receiving Communication</h3>

The person on the other end of the communication should be a good listener. For example in the example given, even if the employer effectively communicates his side of the communication, but the employee is not paying his full attention to what his boss is saying, he wouldn't be able to make much of a difference.

<h3>3) Feedback</h3>

After sending and receiving communication, feedback should be given to complete the communication effectively. For example the employer may tell his boss about what he understood from his boss's speech, or what will he do to improve his performance.

Will a pair of parallel current-carrying wires exert forces on each other? 1. yes; the wires are electrically charged. 2. no; th
Naddika [18.5K]
Number 3.

When you have two parallel wire and the charges are moving, they create a magnetic field around the wire (right-hand rule, thumb points in the direction of current).

If you want the math, here ya go:

\frac{F}{L} = \frac{4 \pi *10^{-7}II' }{2 \pi r}

F: magnetic force on the wire, L: length of the wire I: current in one wire I': current in other wire r: distance of the wire.

As we can see, two wires that has current through it will generate a force on each other.

What do I have to do to figure out " What % of an object’s mass is above the water line if the object’s density is 0.82g/ml " wi
blsea [12.9K]

Answer:

18%

Explanation:

There are two equal and opposite forces on a floating object: weight and buoyancy.

W = B

The weight of an object is its mass times gravity: W = mg

Buoyancy is the weight of the displaced fluid: W = mf g

Plugging in:

mg = mf g

m = mf

Mass is density times volume:

ρV = ρf Vf

Solving for the ratio of Vf / V:

Vf / V = ρ / ρf

Given that ρ = 0.82 g/mL and ρf = 1.00 g/mL:

Vf / V = 0.82

That means 82% of the object's volume (and therefore, 82% of its mass, assuming uniform density) is submerged.  Which means that 18% is above the water line.
