Answer:
empty
Explanation:
Nutritionists call the calories found in junk food empty calories due to lack of quality nutrients.
Empty calories refer to calories derived from foods containing no quality nutrients. These foods are mainly junk food; food that contains high calories derived from fat or sugars and with little or no proteins, fiber, dietary minerals or vitamins. These foods are not healthy as their prolonged consumption can lead to an increased risk of obesity.
Complete Question
Planet D has a semi-major axis = 60 AU and an orbital period of 18.164 days. A piece of rocky debris in space has a semi major axis of 45.0 AU. What is its orbital period?
Answer:
The value is 
Explanation:
From the question we are told that
The semi - major axis of the rocky debris 
The semi - major axis of Planet D is 
The orbital period of planet D is 
Generally from Kepler third law
Here T is the orbital period while a is the semi major axis
So
=> ![T_R = T_D * [\frac{a_R}{a_D} ]^{\frac{3}{2} }](https://tex.z-dn.net/?f=T_R%20%20%3D%20T_D%20%2A%20%20%5B%5Cfrac%7Ba_R%7D%7Ba_D%7D%20%5D%5E%7B%5Cfrac%7B3%7D%7B2%7D%20%7D)
=> ![T_R = 18.164 * [\frac{ 45}{60} ]^{\frac{3}{2} }](https://tex.z-dn.net/?f=T_R%20%20%3D%2018.164%20%20%2A%20%20%5B%5Cfrac%7B%2045%7D%7B60%7D%20%5D%5E%7B%5Cfrac%7B3%7D%7B2%7D%20%7D)

Answer:
electric potential energy
Explanation:
Electric potential energy is a energy that is needed to move a charge against an electric field. You need more energy to move a charge further in the electric field,but also more energy to move it through a stronger electric field.
∆x (displacement) = v - u
where, v is the final position and u is the initial position.
Given, the final position of the object is 0 m and the initial position is 5 m.
∆x (displacement) = v - u
= 0 m - 5 m
= -5 m
Therefore, <u>C: -5m</u> is the correct answer.
