Answer:

x = 2190[days]

Explanation:

This problem can be solved by means of a simple three rule:

1.5*10^{11}=365[days]\\ 6*(1.5*10^{11})=x\\\\x= \frac{6*(1.5*10^{11})*365[days]}{1.5*10^{11}} \\x=2190[days]

 Why are radio waves safer to humans than X- Rays
julsineya [31]

Answer:

Explanation:

Since X-rays are high (energy) frequency photons and radio waves are composed of low (energy) frequency photons, X-rays are more energetic and can do more harm to organic materials (such as cells).

A resistor is made out of a long wire having a length L. Each end of the wire is attached to a termina of a battery providing a
Len [333]

Answer:

B) 2I

Explanation:

The equation that relates voltage, current and resistance is V=RI.

The equation for the resistance of a material in terms of its resistivity, length and cross-sectional area is R=\frac{\rho L}{A}

In this case, the length is divided by 2 while keeping its resistivity (since it's the same material) and area, which means the resistance gets divided by 2. Then, looking at the equation I=V/R and keeping V constant, one deduces that since the resistance now is half than before then current now must be twice as before.

This is all intuitive in fact, cuting a homogeneous resistor in half and leaving the rest of the variables constant makes twice as easy for the electrons to cross the conductor, thus twice the current (one has to know that all the variables involved behave linearly, as the equations show).

A cube with sides of area 22 cm2 contains a 21.2 nanoCoulomb charge. Find the flux of the electric field through the surface of
VladimirAG [237]

Answer:

Explanation:

According to Gausses theorem, electric flux coming out of  charge   on all sides q is equal to

q / ε₀

q is charge , ε₀  is permittivity of air whose value is given by

8.85 x 10⁻¹²; q = 21.2 x 10⁻⁹ C

Putting the values we get

FLUX = \frac{21.2\times10^{-9}}{8.85\times10^{-12}}

2.4 x 10³ Nm²/C
