How is thermal energy from the sun distributed on Earth ?

Physics
1 answer:
Mrac [35]3 years ago

Conduction and convection both require some material substance
to move heat from one place to another, and there's none of that
between the sun and Earth. 

The only way for thermal energy to move from place to place with
nothing in between is by the process of radiation, and that's how
it gets here from the sun.

An angle has a value of 2.2 radians. Find its value in degrees.
Irina18 [472]

Answer:

The value of 2.2 radians in degree is 126.11°.

Explanation:

Given that,

Angle = 2.2 radians

We need to calculate the value in degrees

We know that,

1\ radians = \dfrac{180}{\pi}

2.2\ radians = \dfrac{180}{3.14}\times2.2

2.2\ radians = 126.11^{\circ}

Hence, The value of 2.2 radians in degree is 126.11°.
