Answer:
1.4 * 10 ^-1 Ω
Explanation:
Hi,
For this question, we gotta use the formula
R = pL/A
p = The resistivity of your material at 20°C
L = length of the wire
A = cross-sectional area
The resistivity of tungsten is 5.60 * 10^-8 at 20°C
By plugging the values, we get:
R = (5.60 * 10^-8)(2.0)/(7.9*10^-7) = 1.4 * 10 ^-1 Ω
When the interfering waves have an amplitude of zero the phenomena is called destructive interference.
It occurs when waves come together in such a way that they completely cancel each other out. When two waves interfere destructively, they must have the same amplitude in opposite directions it means that the waves are in 180° different phase from each other.
Answer:
A.
Explanation:
all i know is that sweat keeps your body from overheating
Answer: 17cm.
Explanation:
The equation you're using is:
Δd = df - di
Which means the change in position is equal to the final position minus the starting position. In this case that works out to 20cm - 3cm = 17cm. We're only interested in how much the snail moved, not how long it took to move, so even though they give a time it actually doesn't matter for this question.
The motion of particles during the transmission of wave energy
is periodic. A periodic wave is a continuous oscillating motion that connects
with simple harmonic motion. It is usual that periodic wave particles also
experiences simple harmonic motion. Additionally, the particles on the surface
of the water travel in circular motions forming a wave across the surface.
