Answer:
Y = 40.94m
Explanation:
The initial speed of the sandbag is the same as the balloon and so is its position, so:
Replacing these values:
Yo = 40m Vo = 5m/s g = 9.81m/s^2 t = 0.25s
We get the position of the sandbag:
Y = 40.94m
Answer:
5.4×10⁶J
Explanation:
1 cal = 4.184 J
1.3×10⁶ cal × (4.184 J/cal) = 5.4×10⁶J
The speed of the mass : <em><u>v = 0.316 m/s</u></em>
<h3>Further explanation</h3>
The energy used to press a spring is included as the potential energy
Can be formulated:
Ep= potential energy
k = spring constant
x = change in spring length
If the spring is released from its pressure, this potential energy will turn into kinetic energy
so applies the law of conservation of mechanical energy (Em)
Ek = Ep
A mass of 2 kg is attached to a spring, a spring constant of 20 N/m, and the spring is compressed 0.1 m past its natural length.
m = 2 kg
k = 20 N/m
x = 0.1 m

<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>
