Answer:
the tension produce by the bird in the wire is 610.3 N.
Explanation:
given information:
mass of the bird, m = 1 kg
distance of two telephone pole, L = 50 m
wire sag, y = 0.2
the tension of the wire can be calculate by the following equation
tan θ = y/(L/2)
= 0.2/(50/2)
= 0.2/25
thus
θ = arc tan (0.2/25)
= 0.46°
according to Newton's first law
ΣF = 0, vertical direction
T sin θ + T sin θ - mg = 0
2 T sin θ = m g
T = mg/2 sinθ
= 1 x 9.8/(2 sin 0.46)
= 610.3 N
Answer:
tectonic plates move in opposite direction
Tectonic plates are not necessarily moving in opposite directions, but if there directions are different they form plate boundaries. If they were moving in the same direction they would become the same plate. The more opposite the direction, the more obvious the fault.
Examples of plate boundaries:
Divergent: moving away from each other - mid-Atlantic ridge
Convergent: moving towards each other - the Himalayas (Indian plate subducting under the Eurasian plate forcing up the mountains)
Transform: sliding laterally along each other - San Andreas fault
Answer:
Es útil porque al saberlo evitas sobrexponerte a problemas como <em><u>enfermedades, desgarros o daños a largo plazo de tu cuerpo.</u></em>
Explanation:
When a person decides to start exercising or some type of physical activity, it is necessary for him to know how much his body can resist that activity during a defined period of time.
If in some way or another your body does not resist physical activity, you can hurt yourself, tear a ligament or muscle or get sick.
One of the most common diseases that almost nobody notices is the increase in circulatory and heart problems.
It is best to know your physical condition, how much weight you can carry with weights, or how long you can last doing physical activities.
The wavelength of a sound wave is related to its frequency by the relationship:
where
f is the frequency
v is the speed of the wave
is the wavelength
The wave in our problem has wavelength of
and speed of
(this is the speed of sound in air), therefore its frequency is
And the period of the wave is equal to the reciprocal of its frequency:
You've described two (2) axes of motion.
The third one would have been up-and-down.
