To get the solution you must need to draw a force triangle. Attach the head of the 60N north force arrow with the tail of the 60N east force arrow. The subsequent is the arrow connecting he tail and head of the two arrows.
You get a right angled triangle, and the resultant is (60^2 + 60^2) ^0.5 = 84.85 N or 85 N northeast.

The visible spectrum is composed of red, orange,yellow, green, blue, violet, indigo.
<h3>What is visible spectrum?</h3>
The visible spectrum refers to the portion of the electromagnetic spectrum that can be seen with the eyes. All other portions of the electromagnetic spectrum are invisible.
The question is incomplete as the details are missing. The visible spectrum is composed of red, orange,yellow, green, blue, violet, indigo.

Explanation:
Rtoal=R1+R2+R3=5+10+15=30
I=V/R 90/30
I=3
De broglie wavelength,
, where h is the Planck's constant, m is the mass and v is the velocity.
![h = 6.63*10^{-34}](https://tex.z-dn.net/?f=h%20%3D%206.63%2A10%5E%7B-34%7D)
Mass of hydrogen atom, ![m = 1.67*10^{-27}kg](https://tex.z-dn.net/?f=m%20%3D%201.67%2A10%5E%7B-27%7Dkg)
v = 440 m/s
Substituting
Wavelength ![\lambda = \frac{h}{mv} = \frac{6.63*10^{-34}}{1.67*10^{-27}*440} = 0.902 *10^{-9}m = 902 *10^{-12}m](https://tex.z-dn.net/?f=%5Clambda%20%3D%20%5Cfrac%7Bh%7D%7Bmv%7D%20%3D%20%5Cfrac%7B6.63%2A10%5E%7B-34%7D%7D%7B1.67%2A10%5E%7B-27%7D%2A440%7D%20%3D%200.902%20%2A10%5E%7B-9%7Dm%20%3D%20902%20%2A10%5E%7B-12%7Dm)
![1 pm = 10^{-12}m\\ \\ So , \lambda =902 pm](https://tex.z-dn.net/?f=1%20pm%20%3D%2010%5E%7B-12%7Dm%5C%5C%20%5C%5C%20So%20%2C%20%5Clambda%20%3D902%20pm)
So the de broglie wavelength (in picometers) of a hydrogen atom traveling at 440 m/s is 902 pm
