One way to improve food security is to avoid food spoilage. Identify the correct ways that Devon reduced food spoilage in the pa

ssage. Devon prepared spaghetti and homemade sauce for dinner. The dinner served up to four people, but only Devon was around to eat it. He brought one serving to his neighbor’s house, and stored the other two servings in the refrigerator. Devon ate one more serving of spaghetti the following day. Later that week, his refrigerator broke and the remaining spaghetti spoiled. He immediately called a repair service and got the refrigerator fixed.

Explanation:

One way to avoid food spoilage is to store the food in a refrigerator or we can cook only the required amount of food that can be consumed completely at a time.

By sharing food with neighbor's Devon also avoided wastage or spoilage of food.

Therefore, we can conclude that the correct ways that Devon reduced food spoilage in the passage is that he brought one serving to his neighbor’s house, and stored the other two servings in the refrigerator. Devon ate one more serving of spaghetti the following day.

The RMS potential difference of an AC household outlet is 117 V. a) What is the maximum potential difference across a lamp conne
Anit [1.1K]

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

This chart shows characteristics of three different waves, all with the same wavelength of 10 m but moving at different Which st
JulijaS [17]

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

\lambda = 10 m

now for wave X

f = 6 Hz

now the speed of this wave is

v_x = 10 \times 6 = 60 m/s

now for wave Y

f = 0.5 Hz

now the speed of this wave is

v_y = 10 \times 0.5 = 5 m/s

now for wave Z

f = 2 Hz

now the speed of this wave is

v_z = 10 \times 2 = 20 m/s

So correct answer will be

Wave X is moving the fastest.

A missile is launched upward with a speed that is half the escape speed. What height (in radii of Earth) will it reach?
timofeeve [1]

Answer:

The height (h) will be: \frac{3}{4}R =h  

Explanation:

The scape speed equation is given by:

v_{scape}=\sqrt{\frac{2GM}{R}}

Now, the speed of the missile is

v_{missile}=\frac{1}{2}v_{scape}

v_{scape}=\frac{1}{2}\sqrt{\frac{2GM}{R}}

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

E_{i}=E_{f}

\frac{1}{2}mv_{scape}^{2}-mgR =-mgh

\frac{1}{2}\frac{2GM}{4R}-gR =-gh

\frac{GM}{4R}-gR =gh

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.

\frac{1}{4}gR-gR =-gh

\frac{1}{4}R-R =-h    

Therefore the height (h) will be:

\frac{3}{4}R =h    

I hope it helps you!
