8 0

Answer:

\boxed{Force \: needed = 50 \: N}

Given:

Mass = 20 kg

Acceleration = 2.5 m/s²

Explanation:

Force = mass × acceleration

= 20 × 2.5

= 50 kg m/s² or 50 N

An EM wave has a wave length of 956 m, What type of electromagnetic waves is this wave
Assoli18 [71]

The electromagnetic spectrum allows finding the result for the question of type of electromagnetic wave has a wavelength of 956 nm

  • The wave is in the near infrared range.

The electromagnetic wave is an oscillation of electric fields and magnets field that sustain each other, this wave time has the characteristics that it can travel without a material medium, for which they are of extreme importance.

Consequently the spectrum of electromagnetic waves to each part has been given a different name second to its use, for example

Range                        Name  

Ultraviolet light          200 to 400 nm

Visible light               400 to 700 nm

Infrared light (heat  ) 700 nm to 1 mm

The latter is subdivided into:

 Near infrared          700 nm to 1000 nm (1 μm)

 Medium infrared        1 μm  to 30 μm

 Far infrared             50 μm to 1000 μm

It indicates that the wavelength of the measured radiation is 956 nm, therefore it is in the near infrared range.

Why does a lunar eclipse last for a few hours whereas a solar eclipse only lasts for a few minutes?
Aneli [31]

Answer:

The type and length of a lunar eclipse depend on the Moon's proximity to either node of its orbit. ... A total lunar eclipse can last up to nearly 2 hours, while a total solar eclipse lasts only up to a few minutes at any given place, due to the smaller size of the Moon's shadow.

Why is friction useful between your feet and the ground?
mixer [17]

Answer:

It allows you to walk faster.

Explanation:  

It is the same force that allows you to accelerate forward when you run. Your planted foot can grip the ground and push backward, which causes the ground to push forward on your foot. We call this grip type of friction, where the surfaces are prevented from slipping across each other, a static frictional force.
