In my opinion, the answer would be d: a universal language. D would technically be more important because there are so many foreign scientific companies and to get the information we need to study the universe, we should communicate and give eachother what we have of our resources as we work for it.
Yes. Everybody on Earth sees the same moon phase at the same time.
Pressure is a force per unit area.
Answer:
it is called an impact collision
Answer:
a) Tc = 750 [N] ;b) See the explanation below.
Explanation:
To solve this problem, we first need a graphical explanation of this, as well as knowing the corresponding questions. Therefore, a search was carried out in google, in the attached image we will find a graphical description of the problem.
b)
The solution of this type of problem corresponds to the use of Newton's third law, applying static which tells us that the sum of the forces in a system in equilibrium without movement must be equal to zero.
a)
In this way we can find by means of a sum of forces on the y axis equal to zero:
- 850 - 450 + 550 + Tc = 0
Tc = 750 [N]
