Light / Radiation. The light radiation defines its color. Thermal radiation for its temperature and the overall appearance of the wavelengths the star emits gives off the info from where astronomers and scientist are able to build up knowledge on the age and current state of the stars
Aluminum metal is a good example of conductor of electricity while glass and paper are good example of insulators.
<h3>What is a conductor?</h3>
A conductor is material that allows easy passage of electric current through the.
<h3>Examples of conductors</h3>
All metals are good examples conductors. such as aluminum, iron, silver, etc.
<h3>What is a non conductor?</h3>
A non conductor or insulator is a material which does not allow easy passage of electric current through them.
<h3>Examples of insulators</h3>
Thus, aluminum metal is a good example of conductor of electricity while glass and paper are good example of insulators.

The first, fourth and sixth options. A person walks up a flight of stairs, wind lifts a balloon into the air, and a weightlifter holds a barbell straight overhead.
Answer:
a) T = 1,467 s
, b) A = 0.495 m
, c) v = 4.97 10⁻² m / s
Explanation:
The simple harmonic movement is described by the expression
x = A cos (wt + Ф)
Where the angular velocity is
w = √ k / m
a) Ask the period
Angular velocity, frequency and period are related
w = 2π f = 2π / T
T = 2π / w
T = 2pi √ m / k
T = 2π √ (1.2 / 22)
T = 1,467 s
f = 1 / T
f = 0.68 Hz
b) ask the amplitude
The mechanical energy of a harmonic oscillator
E = ½ k A²
A = √2 E / k
A = √ (2 2.7 / 22)
A = 0.495 m
c) the mass changes to 8.0 kg
As released from rest Ф = 0, the equation remains
x = A cos wt
w = √ (22/8)
w = 1,658
x = 3.0 cos (1,658 t)
Speed is
v = dx / dt
v = -A w sin wt
The speed is maximum when without wt = ±1
v = Aw
v = 0.03 1,658
v = 4.97 10⁻² m / s
The amoeba is having a asexual reproduction and the two birds are not. The two birds are having a sexual reproduction.
