Which is the wavelength of a wave that travels at a speed of 3.0 × 10^8 m/s and has a frequency of 1.5 × 10^16 Hz?

Physics

Answer:

2 x 10^-8

Explanation:

the formula of wavelength is

the speed divided by frequency

so you have the speed given = 3.0x10^8m/s

and frequency = 1.5×10^16 Hz

so wavelength = 3.0x10^8m/s / 1.5x10^16 Hz

Through what process is carbon pulled from the atmosphere in the carbon cycle
Andrei [34K]

Carbon is pulled from the atmosphere in the carbon cycle through the process of photosynthesis. Details about photosynthesis can be found below.

<h3>What is photosynthesis?</h3>

Photosynthesis is the process whereby green plants obtain their nutrition by utilizing energy from sunlight.

Green plants absorb carbon in the form of carbon dioxide from the atmosphere and use it in the photosynthetic process.

This means that one way that carbon is removed from the atmosphere during the carbon cycle is through photosynthesis.

Describe how mass and distance affect gravitational force?
ryzh [129]
It depends. The strength of gravitational force between non other than two objects depends on two factors. Mass and distance. The force of gravity and masses exert on each other. Making a consequence if one of the masses are doubled, the force of gravity of the the objects is doubled.

Hope this helps.

You are working for a manufacturing company. Your supervisor has an idea for controlling the position of a small bead by using e
Mashutka [201]

You are working for a manufacturing company, which is mathematically given as

  • m=3\sqrt{2}
  • m=\frac{15\sqrt{5}}{16}
  • x=0.747a
  • m/n=\frac{(x^2+a^2)3/2}{x^3}

<h3>What is the value of m that will place the movable bead in equilibrium at x-a a ....?</h3>

a)

Generally, the equation for the force of equilibrium is mathematically given as

F=2fcos\theta

Therefore

K(npq^2/a^2)=2\frac{kmpq^2}{a\sqrt{2}^2}0.5\\\\np=mP/ \sqrt{2}\\\\where n=3

m=3\sqrt{2}

b)

By force equilibrium

K(npq^2/(2a^2))=2*\frac{kmpq^2}{a\sqrt{5a}^2}* \frac{2a}{\sart{5a}}

Therefore

n/4=2/5*m*2/\sqrt{5}\\\\m= \frac{5\sqrt{5}}{16}\\\\\\\\

m=\frac{15\sqrt{5}}{16}

c)

K(npq^2/x^2)=2\frac{kmpq^2}{a\sqrt{x^2+a^2}^2}0.5*x/\sqrt{x^2+a^2}

x^2+a^2=(14/3)^{2/3}x^2

x=a/1.338

x=0.747a

d)

By force equilibrium

K(npq^2/x^2)=2\frac{kmpq^2n}{\sqrt{x^2+a^{3/2}}^2}\\\\n/x^2=\frac{2mx}{(x^2+a^2)^{3/2}}

m/n=\frac{(x^2+a^2)3/2}{x^3}

Two long straight parallel wires seperated by 20cm apart carry current of 20A and 1OA in opposite directions. What is the magnit
kati45 [8]

Answer:

<u>Force</u><u> </u><u>is</u><u> </u><u>2</u><u> </u><u>×</u><u> </u><u>1</u><u>0</u><u>^</u><u>-</u><u>4</u><u> </u><u>N</u>

Explanation:

{ \bf{F =  \frac{ \gamma_{o} I _{1} I _{2} l}{2\pi r} }}

F is force

I is current

r is separation distance

gamma is a constant

l is wire length

F =  \frac{(4\pi \times  {10}^{ - 7}) \times (20) \times (10) \times 1 }{2\pi \times 0.2}  \\  \\ F = 2 \times  {10}^{ - 4}  \:  \: newtons
