Answer:
i think it's hydropower??
Explanation:
not for sure, just taking a guess
let me know if it helped haha
1. Both objects have mass and therefore have a gravitational force.
2. Lower mass objects have less gravitational force.
3. Higher mass objects have stronger gravitational force.
Explanation:
To solve this problem, we need a recap of the newton's law of universal gravitation:
The law states that "the gravitational force of attraction between two object is directly proportional to the product of their masses and inversely proportional to the square of the distances between them."
F =
}{
}[/tex]
G = universal gravitational constant
m₁ = mass of object 1
m₂ = mass of object 2
r² = distances between the two masses
From this we can infer that, for gravitational force to exists, both objects must have mass.
Since mass is directly proportional the gravitational force, the lower the mass the less the gravitational force and the higher the mass the stronger the gravitational force.

Answer:
Gastrovascular Cavity
Explanation:
Hydra is commonly found in freshwater ponds and ditches as solitary organisms, in underside of aquatic leaves and lily pads in cool,clean freshwater pools and streams. It has a *Cylindrical body shape*.
Hydra possesses an internal body cavity, the *Gastrovascular cavity *,lined by gastrodermis and has a single opening,the mouth,which serves as an anus.
The Gastrovascular cavity of Hydra is a site for *digestion and nutrient distribution*,and also serves as anus.
