This is not a question we can answer, this is a question only you can answer because it is asking for your personal belief on wether alien's exist outside of earth or not.
Explanation:
Calories from saturated fats and/or added sugars in foods that have little or no nutritional value, such as sausages and ice cream, are called Empty Calories.
Calories can be defined as the amount of energy extracted from the food which an individual eats throughout the day. According to dietary guidelines, a young person [20-25 years old] must intake between 1,600 and 3,000 calories per day.
Foods such as sausages, ice cream, pizza, and soft drinks have a high amount of empty calories because solid fats and added sugars are used in their manufacturing to add flavors and make the food more appealing but they have no nutritional value.
The amount of empty calories a person intakes should be decreased by avoiding such food items and drinks.

The way in which you need to solve this is by using the formula:
<span>R = ρL/A
</span>That one is the formula that demonstrates <span>Resistance of a wire in Ω.
The formula can be explained like this:
</span><span>ρ is resistivity of the material in Ω-m </span>
<span>L is length in meters </span>
<span>A is cross-sectional area in m² </span>
<span>A = πr², r is radius of wire in m
As soon as you have your numbers, you can replace and proceed to get the asnwer</span>
