it is equal to the speed (v) of a wave train in a medium divided by its frequency (f): λ = v/f. Waves of different wavelengths.
Answer:
It is measured in the direction of the wave. Description: Wavelength is the distance from one crest to another, or from one trough to another, of a wave (which may be an electromagnetic wave, a sound wave, or any other wave).

the force required to lift a load of 800 Newton by using a Lever having a mechanical advantage of 1.6 is
Answers
Answer:force required to lift the load = 500N
Explanation:
Mechanical advantage for a lever is given by the formulae
= force output/force input
or
Mechanical Advantage = Load / Effort
where
Force output / Load= 800 N
mechanical advantage = 1.6
Force input / Effort =??
Force input= Force output /Mechanical advantage
= 800N / 1.6
=500N
OR
Effort = Load/ Mechanical Advantage = 800/ 1.6 = 500N

Qué estudios se realizan en la actualidad para utilizar la electricidad de una manera más eficiente?
Answers
Answer:
Se realizan estudios en tres áreas: a) Procesos de transformación de la energía, b) Almacenamiento de la energía, c) Gestión inteligente entre consumo y generación.
Explanation:
Actualmente, se están realizando estudios en principalmente en tres áreas cruciales: a) Procesos de transformación de la energía, b) Almacenamiento de la energía, c) Gestión inteligente entre consumo y generación.
a) Se están desarrollando nuevos materiales que permiten mayor eficiencia entre la energía recibida y la energía eléctrica, además de una mayor durabilidad frente a las condiciones ambientales. Esto implica el mejoramiento del desempeño de las tecnologías basadas en las energías renovables y limpias, acortando su brecha con las energías no renovables.
b) Se están desarrollando nuevos materiales que garanticen una mayor densidad energética y mayor durabilidad, significando baterías más compactas, con mayor capacidad y más competitivas económicamente.
c) Se están desarrollando estrategias de control inteligente a tiempo que permite sincronizar el consumo y la generación, además de posibilitar el flujo bidireccional de la energía a través de una red inteligente (smart grid) e integrar mejor las fuentes renovables dentro de la matriz energética.

What is a curved line in velocity time graph represent?
Answers
So what is the slope of a Vt graph represent? Well, slope is rise over run, aka delta V over delta t. That’s just the formula for acceleration.
We know the slope is changing, and the slope is acceleration, therefore we can say that the acceleration is changing.
It turns out that if you graph this changing acceleration with time, the acceleration changes at a constant rate - it’s linear, NOT a curve. (If you have specific values you could plot this, but if you’re just talking about general graphs, then just take my word for it).
In summary - if you’re velocity is changing at a non constant rate, then you’re acceleration must be changing (at a constant rate).

What is the only part in our body we do not stretch?
Answers
Answer:
The quadriceps consists of four muscles: the skinny rectus femoris and the three huge “vasti” — vastus lateralis/intermedius/medialis. The vasti are only elongated by knee flexion, which is limited to about 120˚ when the calf hits the hamstrings. The vasti cannot be stretched strongly.
Answer:Masseter and temporalis
Why it’s unstretchable: The jaw can only open so far.
Why it’s a dang shame: Jaw tension is epidemic, and trigger points in these muscles cause a wide array of strange face and head pains, including toothaches, headaches, and earaches.

What is Newton's Second Law?
1.The attraction between objects
2.An object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted upon by an unbalanced force
3.An object's acceleration depends on its mass and on the net force acting on it.
4.For every action there is an equal and opposite reaction
Answers
Answer:
An object's acceleration depends on its mass and on the net force acting on it.
Explanation:
Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.

3.An object's acceleration depends on its mass and on the net force acting on it.

An 80 kg skier stands at the top of a 40-meter slope. She then skis down the slope. What is her approximate speed at the bottom of the slope if friction is negligible and her kinetic energy is 31360 J?
Answers
Thank you for that information. If we know her mass and kinetic energy, then we don't need any of that other business about the height of the slope, her skiing ability, the friction of the snow, what she uses to wax her skis, the color of her parka, or what she had for lunch at the chalet. The mass and kinetic energy are enough to answer the question.
Kinetic Energy = (1/2) · (mass) · (speed)²
31,360 J = (1/2) · (80 kg) · (speed)²
speed² = (31,360 J) / (40 kg)
speed² = 784 m²/s²
speed = 28 m/s

Please find the attached file of the complete question:
Given:
[tex]m= 2.2 \ kg\\\\t= 40 \ ms[/tex]
Using formula:
[tex]\to F=ma[/tex]
[tex]= 2.2 \ (a)\\\\= 2.2 \ \frac{dv}{dt}[/tex]
but
[tex]\to F= f(t)\\\\[/tex]
[tex]\to 2.2 \ a= f(t)\\\\ \to 2.2 \ \frac{dv}{dt}=f(t)\\\\ \to \int^{v}_{0} \ dv =\int^{t= 40 ms}_{0} (\frac{f(t)}{2.2}) \ dt\\\\[/tex]
[tex]\to v= \frac{\text{(Area of given graph)}} {2.2} \\\\[/tex]
[tex]=\frac{1}{2} \times \frac{1}{2.2} \times 40 \times 40 \times 10^{-3} \ s\\\\= \frac{1}{4.4} \times 40 \times 40 \times \frac{1}{1000} \ s\\\\= \frac{1}{4.4} \times 16 \times \frac{1}{10} \ s\\\\= \frac{16}{44} \ s\\\\= 0.36363 \ \frac{m}{s}[/tex]

According to Newton's second law equation, what is the relationship between net force applied and the acceleration of the object
Acceleration is inversely proportional to the net force
if acceleration goes up forces goes down
if acceleration goes down mass goes down
Acceleration is directly proportional to the net force
Answers
Answer:
Acceleration is directly proportional to the net force
Explanation:
The net force acting on an object is given by :
F = ma
Where
m is mass
and
a is acceleration
It can be seen that the relation between the net force and the acceleration is direct i.e. as the acceleration increases, the net force will increase. Hence, the correct option is (d).
