Having just enough weight to achieve all three states of buoyancy with only minor adjustments in the water is the definition of:

eduard

Answer:

Proper weighting

Explanation:

Proper weighing involves the condition of a scuba diver that is fully geared having a near empty tank and the BCD emptied with a held breadth is expected to float at eye level

The fundamental of adequate or good buoyancy of a scuba diver is to ensure proper weighting when diving, With proper weighting, there is more control for the diver when a safety stop is required. There is less need to carry excess weight that increases drag and gas consumption.

Why alloys<br> are useful to someone with no science<br> knowledge<br><br> Will give Brainiest

Answer:

The key idea behind the synthesis, processing and application of alloys consist in combining desire qualities from each mineral component in the form of a material.

Explanation:

The key idea behind the synthesis, processing and application of alloys consist in combining desire qualities from each mineral component in the form of a material. For example, steel is the combination of iron, which is ductile but prone to rusting in wet environments, and carbon, which offers high hardness and additional resistence to rusting in wet environments, but is fragile. Hence, steel is more resistant to rusting, ductile as iron and more resistant than iron.

Q|C A lightbulb marked "75 W [at] 120 V " is screwed into a socket at one end of a long extension cord, in which each of the two

VashaNatasha [74]

The actual power that is delivered to this lightbulb would be less than 75 Watts due to resistance of the conducting wires. Consequently, the resistance of these conducting wires would cause a voltage drop and as such reducing the power.
The circuit diagram for the connection of this lightbulb is shown in the image attached below.
The actual power delivered to this lightbulb is equal to 73.8 Watts.

<h3>How to calculate the power delivered to the lightbulb?</h3>

Mathematically, the power delivered to this lightbulb can be calculated as follows by using this formula:

Power, P = IV

Where:

I represents the current.

V represents the voltage.

Basically, the actual power that is delivered to this lightbulb would be less than 75 Watts due to resistance of the conducting wires. Consequently, the resistance of these conducting wires would cause a voltage drop and as such reducing the power.

Also, the circuit diagram for the connection of this lightbulb is shown in the image attached below.

<h3>How to determine the actual power delivered to this lightbulb?</h3>

First of all, we would determine the resistance in this electrical circuit:

P = IV = V²/R

R = V²/P

R = 120²/75

Resistance, R = 192 Ohms.

For the total equivalence resistance, we have:

Total equivalence resistance = 0.8 + 0.8 + 192

Total equivalence resistance = 193.6 Ohms.

Next, we would determine the current in this electrical circuit by applying Ohm's law:

V = IR

I = V/R

I = 120/193.6

Current, I = 0.62 Ampere.

Now, we can calculate the actual power delivered to this lightbulb:

P = I²R

P = 0.62² × 192

Actual power, P = 73.8 Watts.

<u>Complete Question:</u>

A lightbulb marked "75 W [at] 120 V" is screwed into a socket at one end of a long extension cord, in which each of the two conductors has resistance 0.800 V. The other end of the extension cord is plugged into a 120-V outlet.

(a) Explain why the actual power delivered to the lightbulb cannot be 75 W in this situation.

(b) Draw a circuit diagram.
