Answer:
343/440
Explanation:
Recall that v=d/t
Now, this is the same thing.
Frequency is 1/T and wavelength is the distance travelled in one period.
So Vs=f*λ
(the greek letter is used as the symbol of wavelength; it's arbitrary)
Answer:
Be sure to unplug the power source of all electrical equipment before working on it. Always pull from the plug, not the cord. Always wear proper non conductive clothing – insulated gloves, non conductive protective apparel and shoes with insulated soles. Avoid loose clothing or ties.
Hello
Let's convert first the height from foot to meters:

This is the space covered by the ball in its accelerated motion, where the acceleration is the gravitational acceleration:

The law of motion is given by

Re-arranging, we can get the total time of the motion:

which is the time the ball takes to hit the ground.
You want all those boxes filled in (0,0)
Answer:
269,000
Explanation:
The distance between Proxima Centauri and the Sun, d₁₁ = 4.246 light years
The distance between Earth and the Sun, d₂ = 1.58 × 10⁻⁵ light years
The ratio of the distances are;
d₁/d₂ = 4.246/(1.58 × 10⁻⁵) = 268734.177215 ≈ 269,000 times
Therefore, Proxima Centauri is approximately 269,000 times further from the Sun than the Earth is from the Sun
