Answer: These are the right answers:
1. es
2. es
3. son
4. es
5. está (make sure you add the accent at the end. Otherwise it translates as "this").
6. está
7. está
8. está
9. estás
10. es
11. eres
12. estar
Explanation: Just to elaborate a little on the answer, it can also be added that in this exercise they are asking you to fill out the blank with the appropriate form of the verbs SER and ESTAR, which translate in English as TO BE. Non-Spanish speakers often find that these two verbs are difficult to differentiate. Although we would need an entire session to explain the different uses of these verbs, I would argue that generally speaking, we use ESTAR when we think that the quality is the result of a transformation, which can be real or supposed. In addition, we use it to place the subject. So, for instance, in sentence 5 it is said: "He is overwhelmed (he has become that way) with his studies (as a result of his studies)," hence the use of the verb ESTAR. We use SER in order to make general judgements, as well as to identify the subject. So, for instance, in sentence 11 it is said: "Julia, you are a good girl."

Explanation:
Hola! Voy a responderte en el mismo idioma de tu pregunta.
Al establecer que<em> la presión del viento sobre las lonas de un velero varía proporcionalmente con el área de las lonas y el cuadrado de la velocidad del viento</em>, puedes escribir una ecuación:

Donde:
- p es la presión del viento,
- k es la constante de proporcionalidad,
- A es el área de las lonas, y
- v es la velocidad del viento.
Del hecho que<em> la presión sobre un pie cuadrado es de una libra cuando la velocidad es de 16 millas por hora</em>, puedes escribir:
- 1 lb/pie² = k × 1 pie² × (16 mph)² ↔ ecuacion 1
<em>Calcula la velocidad del viento en millas por hora cuando la presión sobre una yarda cuadrada es de 36 libras. (1 yarda = 3 pies):</em>
- p = 36 lb/yarda² × (1 yarda/3pie)² = 4 lb/pie²
- A = 1yarda² × (3pie/yarda)² = 9 pie²
- 4lb/pie² = k × 9 pie² × v² ↔ ecuacion 2
Divide la ecuación 2 por la ecuación 1, para eliminar la constante, k:
