Answer:
Explanation: The Earth's surface is constantly changing through forces in nature. The daily processes of precipitation, wind and land movement result in changes to landforms over a long period of time. Driving forces include erosion, volcanoes and earthquakes. People also contribute to changes in the appearance of land.
Answer:
a) p = m1 v1 + m2 v2
, b) dp / dt = m1 a1 + m2 a2
, c) It is equivalent to force
dp / dt = 0
Explanation:
In this problem we have two blocks and the system is formed by the two bodies.
Part A. Initially they ask us to find the moment of the whole system
p = m1 v1 + m2 v2
Part B.
Find the derivative
dp / dt = m1 dv1dt + m2 dv2 / dt
dp / dt = m1 a1 + m2 a2
Part C.
Let's analyze the dimensions
m a = [kg] [m / s2] = [N]
It is equivalent to force
Part d
Acceleration is due to a net force applied
Part e
The acceleration of block 1 is due to the force exerted by block 2 during the moment change
Part f
Force of block 1 on block 2
True f12 = m1a1 f21 = m2a2
Part g
By the law of action and reaction are equal magnitude F12 = f21
Part H
dp / dt = 0
Isolated system F12 = F21 and the masses are constant. The total moment is only redistributed
The answer is E. Short and thick while cold.
This question can be solved using the concept of the composition of the vector.
(a) The magnitude of F is b "164.27 N".
(b) The angle of the vector from horizontal is " ".
(a)
From the composition of the rectangular components of a vector, we know that the magnitude of the resultant vector is given by the following formula:

where,
= x-component of the force = 122 N
= y-component of the force = 110 N
Therefore,

<u>F = 164.27 N</u>
(b)
The angle of the vector is given by the following formula:

<u>θ = 42.04°</u>

<h2>
Answer: A. land-based</h2>
Explanation:
An artificial satellite is one that is launched into space to orbit the Earth (or another body of the solar system) for various purposes.
In this sense, the characteristics of an artificial satellite will depend on its purpose and functionality. From there we can list: meteorological satellites (for weather) , telecommunications satellites, remote sensing satellites, global positioning systems satellites, environmental satellites, research satellites, among others.
In addition, their orbits can be classified according to their height and inclination, depending on the use they have.
On the other hand, one of the main conditions for a satellite to be considered as such is that it must be kept orbiting. This means, it must not touch land during its useful life, even if it remains in constant contact with its earth based control stations.
Therefore,<u> a land-based is not a type of satellite.</u>
