Why are some starburst galaxies much brighter in infrared than they are in visible light?

1 answer:

4 0

Some starburst galaxies are much brighter in infrared radiation than they are in visible light because the dust surrounding the galaxies warms up and emits infrared light after absorbing visible light. Because of this, starburst galaxies produce up to 98% of their total energy in the infrared, making them some of the brightest infrared objects in the cosmos.

A sort of radiant energy that we experience as heat but that is invisible to human eyes is infrared radiation (IR), often known as infrared light. The sun and fire are two of the most prominent sources of IR radiation, however all objects in the cosmos release some of it.

Does the mass of a pendulum affects the period of oscillation

pshichka [43]

Mass does not affect the pendulum's swing. The longer the length of string, the farther the pendulum falls; and therefore, the longer the period, or back and forth swing of the pendulum. The greater the amplitude, or angle, the farther the pendulum falls; and therefore, the longer the period.

A person is standing on a level floor. His head, upper

BabaBlast [244]

Answer:

$y_{cg} = 1.03 m$

Explanation:

Given data:

weigh (head+arms + head) w_1 = 438 N

centre of gravity y_1= 1.28 m

weigh (upper leg) w_2 = 144 N

Center of gravity y_2 = 0.760 m

weigh ( lower leg + feet) = 87 N

centre of gravity = y_3 = 0.250 m

location of center of gravity $= \frac{w_1 y_1 + w_2 y_2 + w_3 y_3}{w_1 +W_2 +w_3}$

$y_{cg} = \frac{438 \times 1.28 + 144\times 0.760 + 87 \times 0.250}{438+144+87}$

$y_{cg} = 1.03 m$

What heat transfer occurs when warm air rises

Leni [432]

Convection. When a fluid such as air or water touches a hot object, it can heat up and then move in bulk as a fluid, thereby carrying the heat quickly to new locations. Hot air rising is a common example of heat convection.
