The force that acts on all objects, all the time on Earth is gravitational force.
The force that surface exert on an object perpendicularly is normal reaction.
<h3>What force acts on all objects, all the time on Earth?</h3>
- Force due to gravity is gravitational pull on objects due to its position on earth's surface.
The force due to gravity on object's is calculated by applying Newton's second law of motion as follows;
F = mg
where;
- m is the mass of the object
- g is acceleration due to gravity
The force that surface exert on an object perpendicularly is normal reaction.
Thus, the force that acts on all objects, all the time on Earth is gravitational force.

The density of mercury is 13560 kg/m³.
Therefore the density of water is about 1000 kg/m³.
1 atm pressure is 101325 Pa.
g = 9.8 m/s²
The height of a water column, h, needed to measure 1 atm is given by
(1000 kg/m³)*(9.8 m/s²)*(h m) = 101325 Pa
h = 1013225/9800 = 10.3393 m = 1033.93 cm
Answer: 10.339 m or 1033.9 cm
They would have the magnetic parts of the rocks oriented differently. This leaves a trace that allow scientists to find out how often this actually happens (as far as I remember, it's on average once in 800 000 years)
Answer:
≅279.02 N, 36° 15' from North to East
Explanation:
You can the theory of triangle of forces to find the answer.
Two forces are acting perpendicular to each other so use Pythagoras theorem to find the magnitude of the resultant force(x).
x² = 225² + 165²
x = 279.02 N
To find the direction use the same force triangle,
