It is the action of friction that slows something moving through air. The larger the object, the more the air resistance acting on the object.
What else can I help you with?
How do they measure temperature?
Using different types of thermometers, thermocouples, thermal resistances, pyrometers, etc.
Unit of electric resistance?
The unit of electric resistance is the ohm, represented by the symbol Ω. It measures the opposition that a material has to the flow of electric current through it. Smaller resistances allow for a larger current flow, while larger resistances restrict the current flow.
When a skydiver jumps out of an airplane there are two forces acting on her gravity and air resistance After falling for a few seconds the forces due to gravity and air resistance balance each other?
Your question is slightly confusing as you seem to have answered it yourself. A little extra though, the speed at which the skydiver is now travelling is called terminal velocity and it is the fastest an object can travel with only gravity + air resistance acting on it as forces. Due to differing air resistances everything has its own unique terminal velocity and it is possible to alter it, this is the principle behind a parachute.
A 3.0 lamp and a 6.0 lamp are connected in serieswhat is the total resistance of the combination?
In a series circuit, the total resistance is the sum of the individual resistances. So, the total resistance of the 3.0 lamp and 6.0 lamp connected in series would be 3.0 + 6.0 = 9.0 ohms.
How would you minimize the heating effect of a current in a circuit?
BY reducing the resistances of the circuit, By using Maximum transfer theorem and Joule's law. Copper wires are better conductors than, for instance, than aluminum wires. After insulation, I placed the circuit in water to keep it from overheating (big heat sink).
Are all resistances in series connections the same?
No, all resistances in series connections are not the same. Different value resistances can be series together. The results of the resistances in series are always the same, they are additive.
How did Algeria's resistances to french rule differ from the east African's resistances to German rule?

What term remains the same across all the resistances in a parallel combination of resistances?
The voltage across the resistors will remain constant.
What are non ohmic resistances?

10 ohms 60 ohmsand 50 ohms are wired in series and connected to a 120-V battery What is the equivalent resistance for this circuit?
For a series circuit such as this, simply add the resistances to get the equivalent resistance.For a series circuit such as this, simply add the resistances to get the equivalent resistance.For a series circuit such as this, simply add the resistances to get the equivalent resistance.For a series circuit such as this, simply add the resistances to get the equivalent resistance.
What happens to the brightness of the light bulbs in a series with a heater?
They dim as the total resistance of series of resistances is the sum of the resistances; and current = V/R.
Is air resistances is conservative force?
No, air resistance is a non-conservative force. It converts the kinetic energy of an object into thermal energy as the object moves through the air, resulting in a loss of mechanical energy. This process is irreversible and does not follow the principle of conservation of energy.
What are the series circuit rules?
current is constant in the series circuit. The resistances of the components add up and the potential differences is divided propotionally over the components depending on their resistances.
How does water resistance works?

What is the resistance of a parallel circuit with resistances 10 ohms and 20 ohms?
To calculate resistance in parallel: 1/R = 1/A + 1/B + 1/C + 1/D ... where R is the final result, and A, B, C... are the individual resistances. For two resistances A and B, you can simply calculate (A x B) / (A + B).
What is the apparent rule for combining resistances in parallel circuits?
The effective conductance is the sum of the individual conductances. "Conductance" is the reciprocal of resistance. Expressing the rule in terms of resistances: 1 / R = 1 / R1 + 1 / R2 + 1 / R3 ... Where "R" is the effective (combined) resistance, and R1, R2, etc. are the individual resistances.
When two lengths of the same uniform wire are connected together the effective resistance is the sum of the separate resistances is this correct?
Yes. Resistances in series add up. RSERIES = Summation1toN RN
