All of those are true, except the one about the radius. 

Both ends of a chord have to be on the circle, but one end
of a radius is at the center, so a radius can't be a chord.

An airplane flies with a constant speed of 800km/h. How far can it travel in 2 hours?
Nataly [62]
Because the airplane flies at 800 km/h, it will fly 800 km in 1 hour.  In order to find how far it travels in 2 hours, we multiply this number by 2.  800*2 = 1600, so the plane will travel 1600 km in 2 hours.

If a 6V battery is connected to a light bulb whose resistance is 55,000Ω How much current will flow in the circuit?
notka56 [123]

Answer:

Current, I = 0.000109 Amps

Explanation:

Given the following data;

Voltage = 6V

Resistance = 55,000 Ohms

To find the current flowing through the circuit;

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

V = IR

Where;

V represents voltage measured in voltage.

I represents current measured in amperes.

R represents resistance measured in ohms.

Making current the subject of formula, we have;

I = \frac {V}{R}

Substituting into the formula, we have;

I = \frac {6}{55000}

Current, I = 0.000109 Amps

Voltage drop is a better measurement of resistance than testing static resistance because ________.
gavmur [86]

Voltage drop is a better measurement of resistance than testing static resistance because: current flow creates heat  which adds to circuit resistance

The current flow or electric current   is the measure of the electrons flow around a circuit. It is measured in amperes or "amps". If the current is higher the electrons flow is greater.

<h3>What is electricity?</h3>

Electricity or electrical energy is the energy that occurs due to the movement of electrons in the materials that are considered conductors.
