Answer:
We live in a very adaptable environment. If we cannot adapt to the environment, we will not be able to survive.
Explanation:
It would have 45 protons, as the atomic number is equivalent to the amount of protons
Answer:
Option (d) is correct.
Explanation:
Work done is given by :
W = Fd, where F is force and d is displacement
Unit of work done :
The SI unit of force is Newton (N) and that of displacement is meter (m). So, the unit of work done is N-m. It is call Joule. It means that the unit of work done is Joule.
Power is given by rate at which the work is done. It is given by :
P = W/t, W is work done and t is time
Unit of power:
Unit of work is Joule (J) and that of time is second (s). It means that the unit of power is Watt and it is equal to Joule/second
Hence, the correct option is (d) "The unit for work is a joule. The unit for power is a watt, which is a joule per second".
<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>
