Answer:
it means an expert verified the answer so its nearly always true
Explanation:
Answer:
Gravitational pull
Explanation:
There are four fundamental forces in nature:
- Gravitational force: it is an attractive force exerted between all objects having mass. Its magnitude is proportional to the product of the masses and inversely proportional to the square of the distance between the objects.
- Electromagnetic force: it is the force exerted between electrically charged object. It can be either attractive ore repulsive. Its magnitude is proportional to the product of the charges and inversely proportional to the square of the distance between the objects.
- Strong nuclear force: it is the force responsible for holding protons and neutrons together in the nuclei of the atoms. It is attractive and acts only on a very short scale.
- Weak nuclear force: it is the force responsible for certain nuclear decay processes (radioactivity).
In this problem, landslides occur when certain masses of terrain are attracted towards the ground - they are attracted because of the gravitational force.
So, the correct answer is
gravitational pull
According to Newton laws of motion,
F = m*a
Here, m = 1,560 Kg
a = 1.30 m/s²
Substitute their values,
F = 1,560 * 1.30
F = 2028 N ~ 2030 N [ Closest value ]
In short, Your Answer would be Option C
Hope this helps!
Answer:1) the total distance is the sum of the two distances
60 km + 45 km = 105 km
2) The displacement is the net movement, or the difference between the initial position and the final position
Call x the initial position, then the final position is x + [60km - 45km]
And the displacement is x + (60km - 45km) - x =60km -45 km = 15 km
Explanation:
<h3><u>Answer;</u></h3>
A. Skeletal muscles, which are made of fibers, nerves, and blood vessels, contract in order to make the body move.
<h3><u>Explanation</u>;</h3>
- <em><u>Muscular tissues functions in movement and locomotion through its direct connection with the skeletal system. </u></em>
- <em><u>Skeletal muscles are responsible for moving the body. The skeletal muscle contractions pull on tendons, which as attached to bones. When the skeletal muscle contraction causes the muscle to shorten, the bone and thus the body par will move. </u></em>
- <em><u>Skeletal muscles also provide structural support for the entire body. </u></em>
