The correct choice would be

D) travel through a vacuum.

Electromagnetic waves are transverse in nature and do not require a medium to travel from one point to another. On the other hand, sound waves are longitudinal waves and require a medium to travel from one point to another. hence sound waves can not travel through vacuum but electromagnetic waves can.

(D. travel through a vacuum.) All waves need a medium to wave. In a vacuum there is no medium to wave.

A stone is thrown vertically upward with an initial speed of 24.7 m/s. Neglect air resistance. The speed of the stone when it is
fredd [130]

Answer:

The speed of the stone when it is 4.66 m higher is 236.057 m/s.

Explanation:

Given the initial velocity and vertical distance, we can use the fourth kinematic equation (v^{2} =v_{o}^{2}+2ay) to find v final, or the v to the left of the equal sign. We know v_{o} (initial velocity) is 24.7 m/s, y (change in vertical distance) is 4.66 m, and a is another way to write g (acceleration due to gravity), or 9.8 m/s^{2}.

From here you could plug in the values and solve for v final, but to make the solving process simpler, we can simplify the given equation, <em>then </em>plug in the known values.

To isolate v final, we can take the square root of v^{2} and do the same to the right side of the equation. Therefore, we can find v final with: v_{o} \sqrt{2ay}, where v initial is outside of the square root because it squared...

If we plug in the known values to the simplified equation, we get: v=24.7m/s*\sqrt{2(9.8m/s)(4.66 m)}

The final answer is 236.057 m/s.

What is the distance between lines on a diffraction grating that produces a second-order maximum for 760-nm red light at an angl
Nataly [62]
The condition for maximum intensity is the same as that for a double slit. However, angular separation of the maxima is generally much greater because the slit spacing is so small for a diffraction grating. For a diffraction grating with lines/mm = lines/inch, the slit separation is d = micrometers = x10^ m.

rjkz [21]

Answer:

80m

Explanation:

potential energy = MGH

p.e = 50 X 10 X h

4x10⁴ = 500 X h

h = 4x10⁴/500

h = 80m

valentina_108 [34]

Answer:

(a) x=ASin(ωt+Ф₀)=±(√3)A/2

(b) x=±(√2)A/2

Explanation:

For part (a)

V=AωCos(ωt+Ф₀)⇒±0.5Aω=AωCos(ωt+Ф₀)

Cos(ωt+Ф₀)=±0.5⇒ωt+Ф₀=π/3,2π/3,4π/3,5π/3

x=ASin(ωt+Ф₀)=±(√3)A/2

For part(b)

U=0.5E and U+K=E→K=0.5E

E=K(Max)

(1/2)mv²=(0.5)(1/2)m(Vmax)²

V=±(√2)Vmax/2→ωt+Ф₀=π/4,3π/4,7π/4

x=±(√2)A/2
