That's false. The half-life of an unstable element
doesn't depend on its environment.

Answer:

True

$Q = 480 \mu C$

Explanation:

As we know that total charge is always quantized and in the terms of multiples of charge of single electron

so we have

Q = Ne

here we know that

$N = 3.0 \times 10^{15}$

also we know that

$e = 1.6 \times 10^{-19} C$

so we have

$Q = (3.0 \times 10^{15})(1.6 \times 10^{-19} C)$

$Q = 480 \mu C$

Since this charge is in multiple of micro coulomb units so yes it is possible to measure it

and the magnitude of this charge is given as

$Q = 480\mu C$

An additional 10ppm of methane will change the upward IR heat flux (in tropical

atmosphere) from 289.29 W/m2

to 286.211 W/m2

, which is a reduction of 3.08

W/m2

An additional 10ppm of CO2 will change the upward IR heat flux from 289.29 W/m2

to 289.29 W/m2

, which is a change of 0.13 W/m2

Therefore, an additional 10 ppm of methane would have a much larger impact on

the outgoing infrared flux than an additional 10 ppm of CO2 at current

concentrations
