There are no good descriptions on that list.
The answer is "Conduct an experiment" :)
<span>density of lead = 11.34 g/cm^3 </span>
<span>mass = density x volume = 11.34 g/cm^3 x 45.3 = 513.7 g is the mass of a cube of lead</span>
Answer: S = 4.67 W/m², U = 1.29 J
Explanation:
Given
Time of flow, t = 12.3 s
Area of flow, a = 0.0225 s
Amplitude, E = 59.3 V/m
Intensity, S = ?
I = E² / cμ, where
μ = permeability of free space
c = speed of light
E = E(max) / √2
E = 59.3 / √2
E = 41.93 V/m
I = 41.93² / (2.99*10^8 * 1.26*10^-6)
I = 1758.125 / 376.74
I = 4.67 W/m²
Energy that flows through
U = Iat
U = 4.67 * 0.0225 * 12.3
U = 1.29 J
Therefore, the intensity is 4.67 W/m² and the energy is 1.29J
HELP ME PLEASE
Silently he crept through jagged thornbushes. Bare feet moved swiftly over hot, arid soil to the edge of a waterhole where the kudu was drinking. The great animal suddenly looked up, spiral horns curving sharply into the endless African sky. Nsue did not reach for his pouch of poisoned arrows. He had no heart for killing. This would not be the day he would change his childish boyhood name.
How does paragraph 1 contribute to Nsue’s development?
A.
It establishes Nsue’s disappointment at not finding a suitable animal to bring to the feast.
B.
It establishes Nsue’s apprehension of participating in the Festival of the New Moon.
C.
It establishes Nsue’s desire to become a great storyteller like Gao, the Old One.
D.
It establishes Nsue’s motivation to find something to take to the feast.
