That way the 5 cm long vector represents 50 km/h
translation: What is the period between crest and crest, if a
wave travels 85ms, if distance
is 4.5m. And what is its frequency.
Lo siento, pero no puedo responder a tu pregunta.
(también la gente informará si lo hace en inglés mentalmente en un idioma diferente, así que ... tal vez traducir)
Explanation:
frequency =speed/wavelength
=5/0.5=10Hz
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]
