I think the correct answer from the choices listed above is option A. The process of conduction is described by the heat energy is transferred from the land to the air by direct contact. Conduction is the process of heat transfer that happens through the collisions between molecules.
Answer:
a. 165.5 V
b. 7.78 A
Explanation:
Here is the complete question
The RMS potential difference of an AC household outlet is 117 V. a) What is the maximum potential difference across a lamp connected to the outlet? b) If the RMS current through the lamp is 5.5 A, what is the maximun current through the lamp.
Solution
a. The maximum potential difference across the lamp V₀ = √2V₁ where V₁ = rms value of potential difference = 117 V
V₀ = √2V₁ = √2 × 117 V = 165.5 V
b. The maximum current through the lamp I₀ = √2I₁ where I₁ = rms value of current = 5.5 A
V₀ = √2V₁ = √2 × 5.5 A = 7.78 A

Answer:
Wave X is moving the fastest.
Explanation:
As we know that the speed of the wave is given as the product of frequency and wavelength
so here we will have

now for wave X

now the speed of this wave is

now for wave Y

now the speed of this wave is

now for wave Z

now the speed of this wave is

So correct answer will be
Wave X is moving the fastest.
Answer:
The height (h) will be:
Explanation:
The scape speed equation is given by:

Now, the speed of the missile is


Using the conservation of energy, we can find the maximu height of the missile.



Let's recall that g = GM/R², using the equivalence principle. When R is the radius of the earth and M is the mass of the earth.

Therefore the height (h) will be:
