Because many objects in space don't radiate any optical (visible) radiation at all.
And other objects, like stars, radiate a lot of invisible radiation in addition to the
visible light from them. So the ability to detect and measure invisible radiation
makes it possible to learn a lot more about objects in space than we could if
we could only use their visible light.
the answer for 0.429m to mm is 429
A scalar is a quantity that is fully described by a magnitude only. It is described by just a single number. Some examples of scalar quantities include speed, volume, mass, temperature, power, energy, and time. A vector is a quantity that has both a magnitude and a direction.
I hope this helps you.
Answer:
Weight, normal force by slope, kinetic friction force by
slope
Explanation:
Answer:
. = 2574.08
Explanation:
given data
magnitude V1 = 80
magnitude V2 = 50
angle a = -37°
solution
= 80 k
= 50 cos{37} i - 50sin{37} k
so that here . is
. = 80 k . ( 50 cos{37} i - 50sin{37} k )
. = 80 k . ( 38.270 i + 32.176 k )
. = 2574.08
