299,792,458 meters per second

(But but, but that's the speed of light !)

(It sure is ! And also the speed of radio, infrared, visible light, ultraviolet light, X-rays and gamma rays. All uvum !)

IRINA_888 [86]

Answer:

Inertia

Explanation:

When the planes moves downward a speed, the weight of the person will decrease a bit due to the amount of g decreases for that particular instant. The person is now experiencing a less than actual weight called as apparent weight due to the upward superposition of inertia on the body as we can see in w = m g .

Dos cargas iguales de 10^-7C estan separadas por una distancia de 2m. calcule la fuerza con que se repelen
m_a_m_a [10]

Answer:

F=2.25\times 10^{-5}\ N

Explanation:

According to question,

Charge 1 and charge 2 are 10^{-7}\ C

The distance between charges is 2 m

We need to find the force with which two positive charges repel. It is called electrostatic force of repulsion. It can be given by :

F=\dfrac{kq^2}{r^2}\\\\F=\dfrac{9\times 10^9\times (10^{-7})^2}{2^2}\\\\F=2.25\times 10^{-5}\ N

So, the electric force of repulsion is 2.25\times 10^{-5}\ N.

san4es73 [151]

Answer:

0.87 m

70.6 Hz

Explanation:

L = length of the rope = 1.30 m

n = order of the harmonic = 3

\lambda = Wavelength

Wavelength is given as

\lambda = \frac{2L}{n}

\lambda = \frac{2(1.30)}{3}

\lambda = 0.87 m

v = Speed of transverse wave = 61.4 m/s

f = frequency of the third harmonic

frequency is given as

f = \frac{v}{\lambda }

f = \frac{61.4}{0.87}

f = 70.6 Hz

Explanation: (To Ship Leesoo) "My name is Twenty-Fifth Baam. For short you can just call me Baam. Even if you tell me to introduce myself, there's not much to say. I don't have parents... or a home... a single set of dirty clothes is all I have. I always thought that I might die alone without ever being able to do anything... But now- I have friends. Thank you."[45]

(To Yu Han Sung) "If Rachel isn't up there, that place is nothing more than a pile of garbage. No matter what's up there, that won't change. You told me that being like I am is strange, but to me, you're a person who can't even find a single thing that's precious within that huge pile of garbage."[49]

(To Androssi Zahard) "If I must fight, I will fight to protect what is precious to me."[48]

(To Hwa Ryun) "What's this rising emotion from my heart... I'm not sure... I have to find out...! Why... Rachel... betrayed... ME...!!"[50]
