"Generally, electromagnetic<span> radiation is classified by wavelength into radio wave, microwave, terahertz (or sub-millimeter) radiation, infrared, the visible region that is perceived as light, ultraviolet, X-rays and gamma rays. The behavior of </span>EM<span> radiation depends on its wavelength."

Explanation:

Hello! Let's solve this!

The electromagnetic spectrum is where we can see all wavelengths. It is an energy distribution and we see electromagnetic waves such as X-rays, gamma rays, microwaves, ultraviolet rays, among others.

We can see which electromagnetic wave has the shortest known wavelength and which wave has the longest known wavelength.

The attractive electrostatic force between the point charges +8.44 ✕ 10-6 and q has a magnitude of 0.961 n when the separation b

d1i1m1o1n [39]

The electrostatic force between two charges Q1 and q is given by
$F=k_e \frac{Q_1 q}{r^2}$
where
ke is the Coulomb's constant
Q1 is the first charge
q is the second charge
r is the distance between the two charges

Re-arranging the formula, we have
$q= \frac{F r^2}{k_e Q_1}$
and since we know the value of the force F, of the charge Q1 and the distance r between the two charges, we can calculate the value of q:
$q= \frac{(0.961 N)(0.67 m)^2}{(8.99 \cdot 10^9 N m^2 C^{-2})(+8.44\cdot 10^{-6}C)}=5.69 \cdot 10^{-6} C$

And since the force is attractive, the two charges must have opposite sign, so the charge q must have negative sign.

The side length of a square is modeled by s=A, where A is the area of the square. Graph the function. What is the side length of

Naya [18.7K]

Answer:

√35 square units

Explanation:

Area of square = 35square units

Formula of area of square is a =s*s where a is area and s is side

So,

s*s = 35

s^2= 35
