Which statements about carbon-14 dating are true? Check all that apply. Carbon-14 decays into nitrogen-14. Carbon-14 has a longe

r half-life than potassium-40. Once a living thing dies, it no longer takes in carbon. Carbon-14 dating is used to date very old volcanic rock. Carbon-14 dating works for fossils as old as 50,000 years.

leva [86]

Is halved. A 6Ω resistor connected to a voltage source which voltage is decreased from 12V to 6V the current passing through the resistor is halved.

The key to solve this problem is applying Ohm's Law V = R I, clearing I from the equation, we obtain I = V/R. Then, the current is directly proportional to the voltage and inversely proportional to the resistance.

V = 12V and R = 6Ω

I = 12V/6Ω = 2A

V = 6V and R = 6Ω

V = 6V/6Ω = 1A

As we can see the current is halved if the voltage descreased from 12V to 6V

The voltage or potential difference provides the ____ required for electrons to travel through a circuit
galben [10]

Answer:

a. push

Explanation:

Voltage is the force or pressure that is responsible for pushing the charge or electrons to flow in a closed-looped electrical circuit. This flow of electrons (charge) is called the electric current. It is also defined as the difference in electric potential per unit charge between two points in an electric field.

docker41 [41]

Answer:

diameter of transmission is 3.473 mm

Explanation:

given data

current = 300 A

total wire length = 1.0 m

voltage drop = 0.55 V

solution

as here Resistivity of copper is = 1.68 × 10^{-8} ohm- m

so we get here resistance of wire that is

resistance = \frac{V}{I}    ..............1

R = \frac{0.55}{310}  

R = 1.774 × 10^{-3}  ohm

and now we get diameter of wire that is

R = \frac{\rho l}{A}    .............2

\pi \frac{d^2}{4} = \frac{\rho l}{R}    

d² = \frac{4\rho l}{\pi R}     ...............3

put here value

d² = \frac{4\times 1.68\times 10^{-8} \times 1}{\pi \times 1.774\times 10^{-3}}  

d = \sqrt{12.064\times 10^{-6}}

d = 3.473 × 10^{-3} m

d = 3.473 mm

so diameter of transmission is 3.473 mm
