A warm copper wire will have more conductivity
<span>95m /2 = 47.5m
47.5m = Vocos38t
</span><span>Vy = Voy -9.8t
0 = Vosin38 - 9.8t
0 = Vosin38 - 9.8(47.5 / Vocos38)
0 = Vo^2(0.62) - 590.7
</span>
<span>Vo = 30.87 m/s
</span>
Hope this helps
Answer:
<h3>The acception and donation of elections within two elements is called as ionic bond.</h3>
<h2>MARK ME AS A BRAINLIST AND FOLLOW ME :)</h2>
<u>We are given:</u>
constant speed of the car (u) = 36.12 m/s
time in question (t) = 12 seconds
<u>Solving for the Distance and Displacement:</u>
from the second equation of motion:
s = ut + 1/2 at^2
since we have 0 acceleration:
s = ut
<em>replacing the variables</em>
s = 36.12 * 12
s = 433.44 m
Since the car is travelling in a straight line towards the same direction, it's Distance will be equal to its Displacement
Hence, both the Displacement and <u>Distance covered by the car is </u>
<u>433.44 m</u>
but since Displacement also has a direction vector along with it,
the <u>Displacement will be 433.44 m due west</u>
Here is your answer
b)
REASON :
We know that
Velocity= Frequency× Wavelength
So,
Frequency= Velocity/wavelength
Here,
V= 3× 10^8 m/s
Wavelength= 2×10^-3 m
Hence,
Frequency= 3×10^8/2×10^-3
= 3/2 × 10^11
= 1.5× 10^11 Hz
