What does the term Milankovitch cycles most closely relate to?

1 answer:

8 0

The term Milankovitch cycles most closely relate to periodic changes in Earth’s orbit and angle of tilt relative to sun. So for this question, the correct option is option “c”. Milankovitch affects actually deals with the effect of the changes in the earth’s movements with the change in the climatic conditions. Milankovitch was a Serbian geophysicist and also a great astronomer. His studies actually helped in relating the climatic changes with the changes in the tilt of the earth. He was the first person to mathematically prove this situation.

Alisiya [41]

24 m/s will be the velocity at this point .

What is velocity?

Velocity is the directional velocity of a moving object, observed from a given frame of reference and indicating the rate of change of position measured at a given time reference (eg 60 km/h northward). Velocity is a fundamental concept in kinematics, a branch of classical mechanics that describes the motion of bodies.

Velocity is a physical vector quantity. The scalar absolute value (magnitude) of velocity is called velocity, and its magnitude is a consistent derived unit measured in the SI (metric) system as meters per second (m/s or m⋅s−1). For example, "5 meters/second" is a scalar, but "5 meters/second east" is a vector. An object is said to be accelerating if its velocity, direction, or both change.

when v= u + at and v2-u2=2as , where u=0 ,t=4 , S = 48 m , manipulate the data and fine the answer.

Indicar objetosque puedan ser observados a simple vista, con microscopio, con microscopio electrico y con miscroscopio de transm

AysviL [449]

Answer:

En esta respuesta voy a usar la unidad μm, tal que:

1 μm = 1*10^(-9) m

Objetos que pueden ser observados a simple vista:

Son todos aquellos objetos que podemos observar simplemente con nuestros ojos, con ellos podemos observar desde un edificio (con tamaños de decenas de metros) hasta algunos cabellos, que pueden tener un diámetro de 0.1 mm

Cosas más pequeñas que estás muy difícilmente se pueden ver a simple vista.

Con un microscopio podremos ver cosas del tamaño de una célula, como glóbulos blancos, rojos, algunos microorganismos, etc, los cuales rondan un tamaño de unos 10 μm. Naturalmente, distintos microscopios tendrán distintas amplificaciones (por lo que con algunos podremos ver objetos muy pequeños que con otros no).

Microscopio eléctrico:

Este microscopio usa electrones en lugar de luz para formar imágenes.

Con él podremos observar cosas como las componentes de una célula (membranas, orgánulos grandes, etc), los cuales pueden medir unos pocos nanómetros (por ejemplo, una membrana celular tendrá un tamaño de entre 5 μm y 10 μm)

Microscopio de transmisión.

Tener en cuenta que el microscopio de transmisión es un microscopio eléctrico, el cual lanza un haz de electrones al objeto que se desea observar, de tal forma que algunos de estos electrones rebotan formando así la imagen virtual amplificada que podemos observar.

Con estos aparatos podemos ver orgánulos pequeños (0.5 μm), y lo más pequeño que podemos ver (con los microscopios más potentes) son columnas de átomos (0.1 μm)

What do u mean by free fall?

Degger [83]

Answer:

Any motion of a body in which gravity is the sole force acting on it is known as free fall. A body in free fall has no force acting on it under general relativity, where gravity is reduced to space-time curvature.

mel-nik [20]

Answer:

Tech B is correct and Tech A is incorrect.

Explanation:

Here Tech A is wrong because when diagnosing an overheating hydraulic system, it is not necessary to un plugg the oil cooler rather it should be plugged to for proper diagnosis.

Technician B says running the hydraulic system at a lower operating temperature will reduce the possibly of oil oxidation is correct statement because at temperature oil's physical as well as chemical property tend to change.

Hence, Tech B is correct and Tech A is incorrect.
