3 0

Answer:

Explanation:

v= u + at

v is final velocity , u is initial velocity . a is acceleration and t is time

Initial velocity u = 0 . Putting the given values in the equation

v = 0 + g sin 18 x 3.5

= 10.6 m /s

When does sea breeze occur
Vladimir79 [104]
<span>Sea breeze can happen during hot summer days because of the uneven  heating rates of water and land. The land surface heats up faster than the surface of the water during the day.  At this rate, the air above the land grows warmer than the air atop the ocean. Warmer air is always lighter than cooler air. As a consequence, warm air is pushed upward causing it to rise. With this, warmer air rises over the land. As warm air rises over the land, cooler air over the ocean flows over the land surface to change or replace the rising warm air.</span>

A wave with a frequency of 325 Hz. is travelling at a speed of 125 m/s. What is the wavelength of this wave?
ollegr [7]

Answer:

0.385 meters

Explanation:

Just remember this very simple equation:

velocity=(wavelength)*(frequency)

I always remember it as "Velma is Waving Frantically"

So, 125=(wavelength)*(325)

Therefore, wavelength=0.385 meters!

Hope this helped!

Which type of multiplexing is defined by wavelength instead of frequency?​ a. ​wdm b. ​cwdm c. ​dwdm d. ​fdm?
Rina8888 [55]
<span>Multiplexing is the process of combining numerous signal of data or sound on to a single carrier like an optical fiber by using different wavelengths. The type of multiplexing that is defined by wavelength instead of frequency is CWDM which is also known as Coarse Wavelength Division Multiplexing.</span>

A Christmas sphere will break if dropped on hardwood floor with a velocity of 2.0 m/s. Mar Estefanía is
Margaret [11]

Answer:

0.17 s

Explanation:

Given:

Δy = 0.15 m

v₀ = 0 m/s

a = 9.8 m/s²

Find: t

Δy = v₀ t + ½ at²

0.15 m = (0 m/s) t + ½ (9.8 m/s²) t²

t = 0.17 s
