<span>D. in back of the lens, because the rays are unaffected until it goes through the lens. In that moment the direction of the rays is modified, making them get closer to each other and all of them converge in a point behind the lens.</span>
There is at least one USCG-endorsed Class B-1 for the fire extinguisher that is required on any powerboat unless it is with the accompanying special case:
1. speedboats under 26 feet long,
2. moved by detachable engines and
3. not conveying travelers for procuring, require not convey such compact fire dousers if
4. the development of such speedboats won't allow the entanglement of touchy or combustible gasses or vapors
an element can make a molecule. so technically yes.
Answer:
<h2>T(Period) = 1.33s</h2><h2>f(Frequency) = 0.75Hz (cycles/second)</h2>
Explanation:
<h2>Given:</h2><h2 /><h2>λ = 4.0m</h2><h2>Amplitude = 25m</h2><h2>d = 24m</h2><h2>s = 8.0s</h2><h2 /><h2>Required:</h2><h2>f = ?</h2><h2>T = ?</h2><h2 /><h2>Analysis:</h2><h2>v = λf</h2><h2>f =N/t</h2><h2>T = 1/f</h2><h2 /><h2>v = d/t</h2><h2 /><h2>Solve:</h2><h2>v = d/t = 24/8.0 → v = 3.0m/s</h2><h2>v =λf → f = v/λ = 3.0/4.0 → f = 0.75Hz</h2><h2>T = 1/f = 1/0.75 → T = 1.33s</h2><h2 /><h2>Hopes this helps. Mark as brainlest plz!</h2>
"Valence" electrons or the free electrons
<u>Explanation:</u>
Electrical conductivity can be defined as the property of the substance to conduct electricity, heat etc through it. This conductivity is caused due to the migration of particles which are electrically charged within the atomic lattice of the substance.
The outermost electrons or the electrons in valence shell are the main cause behind the conductivity property exhibited by any substance. Higher the number of electrons in outer shell, higher the conductivity.
Since these electrons are in the outermost shell, they can move easily. Under an impact of applied heat, charge these electrons migrate through the atomic lattice and thus conducts electricity, heat as the case may be.
