Answer: 131.92 m
Explanation: The problem give above is a conversion problem. To convert any measurement from one unit to another, we need a relation for the original units to that of the desired unit. This relation is called the conversion factor. It is used by multiplying or dividing the factor depending on what is the unit of the original measurement. For this case, we need to convert from ft^2 to m^2. The conversion factor would be 1 foot is equal to 0.3048 m. So, we would be getting the square of the factor and then multiply to the original value.
1420 ft^2 ( 0.3048 m / 1 ft)^2 = 131.92 m
Velocity of the wave is 1.7 m/s
Explanation:
As we know that the frequency of the wave is defined as the number of waves crossing a fixed point per second
So here we will have
Also we know that the distance between two consecutive crest or two consecutive trough is known as wavelength
So here the wavelength of the wave is given as
now we have
Answer:
<em>Two</em><em> </em><em>sides</em><em> </em><em>and</em><em> </em><em>angle</em><em> </em><em>between</em><em> </em><em>them</em><em> </em><em>is</em><em> </em><em>given</em><em> </em>
<h2>Answer</h2>
Option A that is 8.8 × 10^3 m/s
<h2>Explanation</h2>
The magnetic field B is defined from the Lorentz Force Law, and specifically from the magnetic force on a moving charge. It says
Field-strength = BVqsinΔ
<h2>v = E/B </h2>
Since field are perpendicular so sin90 = 1
v = 4.6/10^4 / 5.2
v = 8846.15 m /s
The speed at which electrons pass through the selector without deflection = 8846.15 m /s
Answer:
0.8 meters.
I just answered this ame question myself on a test I was taking.
