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.

The field is
<em><u>E</u></em> = 1 / (4 pi ε₀) Q / <em><u>R</u></em>² directed radially outward from
the center of the shell.
R is the radius of the spherical shell.
Notice that the field is exactly the same as the field due to a point-charge
with magnitude 'Q' that's located at the center of the sphere.
Answer:
a) 4.9 s
b) 167.8 m
Explanation:
Hello!
To solve this question we need to make use of the equations of motion of both the motorcycle xm(t) and the car xc(t) at t=5
Let us consider the position of the motorcycle at t=5 as the origin, that is:
xm(t+5) = vt + (1/2)at^2
xc(t+5) = vt + 60 m
where v = 22.0m/s and a=5m/s^2
We are looking for the time t' when the position of the car and the motorcycle are the same:
xm(t'+5)=xc(t'+5)
vt' + (1/2)at'^2 = vt' +60m
t' = √(120 m /a) = 4.89898... s
Since we are considering the origin of the cooordinate system at the position when the motorcycle starts to accelerate, the distance travelled by the motorcycle until it catches the car is given by:
xm(t'+5)= vt' + (1/2)at'^2
xm(9.89898s) = (22 * 9.89898 + 2.5 * 9.89898^2)m
xm(9.89898s)= 167.777... m
Answer:
Charge on two particles is given as

As we know that the electrostatic force between two charges is given by formula
so we will have
so we have

When fossil fuels are burnt, what 2 gases are given off?
When fossil fuels are burnt, the following are one of the two gases when they are given off:
→ Carbon dioxide: Carbon dioxide is a green house gas, and plays a major role in the global warming.
→ Carbon Monoxide: Carbon monoxide is a gas that is dangerous to human beings when released.
Hope I helped (:
Have a great day!
