Different stages of the cycle gives off different wavelengths of light because more types elements are being made as you go farther down the cycle. So looking at the wavelengths that the light gives off can determine what stage a star is currently in

You are dragging a block on a surface with friction at a steady speed of 2 m/s and exert a force of 5 N to do so. What is the fo

m_a_m_a [10]

Answer:

Friction = 5 N

Explanation:

As we know that block is moving at constant speed

So the acceleration of the block is zero

So we will have

$F_{net} = 0$

for net force to be zero

Force exerted on the object by external system must be counter balanced by the force of friction

So we have

$F_{ex} = F_f$

so we have

$F_f = 5 N$

A common technique in analysis of scientific data is normalization. The purpose of normalizing data is to eliminate irrelevant c

nataly862011 [7]

Answer:

V₂ = 0.4432

Explanation:

The normalize procedure is widely used in science, in this case we are going to normalize to the voltage value that exists 4 cm away

Vₙ= V_{measured} / V₀

where the voltage at the desired distance is V₀ = 185 mV = 0.185 V

the normalized voltage are

forr x = 4 cm

V₁ = 185/185

V₁ = 1

for x = 6.2 cm

V₂ = 82/185

V₂ = 0.4432
