Radio wave radiation falls in the wavelength region of 10.0 to 1000 meters. What is the energy of radio wave radiation that has

dmitriy555 [2]

Answer:

Explanation:

Given

Wavelength of radiation $\lambda =784\ m$

We know Energy of wave with wavelength $\lambda$ is given by

$E=\frac{hc}{\lambda }$

where h=Planck's constant

c=velocity of light

$\lambda$ =wavelength of wave

$E=\frac{6.626\times 10^{-34}\times 3\times 10^8}{784}$

$E=2.53\times 10^{-28}\ J$

Hence the energy of the wave with wavelength 784 m is $2.53\times 10^{-28}\ J$

Two students play tug of war. Jack pulls East with a force of 82 Newtons while Tony pulls west with a force of 96 Newtons. Which

lorasvet [3.4K]

The net force on the center of the rope is C. 14 N West

Explanation:

We have two forces acting on the rope:

- The force applied by Jack, 82 N, towards East

- The force applied by Tony, 96 N, towards West

Taking East as positive direction, we can rewrite the two forces as

$F_1 = +82 N\\F_2 = -96 N$

where the second force is negative since its direction is west.

The two forces act along the same line, so we can calculate their resultant by simply calculating their algebraic sum. Therefore:

$F=F_1+F_2=+82+(-96)=-14 N$

And the negative sign tells us that the direction is West.

Answer:

a. Zombie

Explanation:

Zombies- A cracker — a computer hacker who intends mischief or harm — secretly infiltrates an unsuspecting victim’s computer and uses it to conduct illegal activities. The user generally remains unaware that his computer has been taken over — he can still use it, though it might slow down considerably. As his computer begins to either send out massive amounts of spam or attack Web pages, he becomes the focal point for any investigations involving his computer’s suspicious activities. In one case of zombies it was found that over 1.5 million computers were affected in an attack.
