Explanation:
Hydrostatic pressure is the pressure exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity. Hydrostatic pressure increases in proportion to depth measured from the surface because of the increasing weight of fluid exerting downward force from above.
The formula is :
P= d x g x h
p: hydrostatic pressure (N/m²)
d: density (kg/m³) density of seawater is 1,030 kg/m³
g: gravity (m/s²) ≅ 9.8m/s²
h: height (m)
It has been proposed that the total number of civilizations that have arisen in our galaxy would be closest to 100,000.
<h3>What is a galaxy?</h3>
A galaxy is a group of stars (solar systems), gas, and dust in a specific position in the Universe.
The Milky Way is the galaxy where we live and it has been proposed that this galaxy is full of dead civilizations.
In conclusion, the total number of civilizations that have arisen in our galaxy would be closest to 100,000.

Answer:
To find the weight of something, simply multiply its mass by the value of the local gravitational field, and you get a result in newtons (N). For example, if your mass is 50 kg (about 110 pounds), then your weight is (50) (9.8). The point that must be overwhelmingly emphasized is that weight is a force.

Answer:
This ball will attain the same range at 60°.
Explanation:
Projectile motion: when an object is thrown in such a way that it form an angle with horizon, the force act on it that is the acceleration due gravity. This type of motion is known as projectile motion.
Range: The horizontal distance is covered by an object.
Range
u = initial velocity = 40 m/s
θ = 30°
g = gravity =9.8 m/s²
Next,
Range and u = 40 m/s
This ball will attain the same range at 60°.
