Answer: Hydrogen and Helium > Hydrogen compounds > Rocks > Metals

Explanation: The solar nebular system contains 98% Light Gases of both Hydrogen and Helium (produced in the Big Bang); followed by 1.4% of Hydrogen Compounds including water, methane, and ammonia; then followed by 0.4% of Rocks like Silicates; and lastly 0.2% of Metals including Iron, Nickel and Aluminium.

An unstable particle at rest spontaneously breaks into two fragments of unequal mass. The mass of the first fragment is 3.00 10-
kirill [66]

Answer:0.478 c

Explanation:

Given

mass of lighter Particle(m_1)=3\times 10^{-28} kg

mass of heavier Particle(m_2)=1.51\times 10^{-27} kg

speed of lighter particle(v_1)=0.834 c

Let speed of heavier particle=v_2

and Momentum of the particle is given by

P=\frac{mv}{\sqrt{1-(\frac{v}{c})^2}}

P_1=\frac{m_1v_1}{\sqrt{1-(\frac{v_1}{c})^2}}

P_1=\frac{3\times 10^{-28}\times 0.834 c}{\sqrt{1-(\frac{0.834 c}{c})^2}}

P_1=8.219\times 10^{-28} kg c

P_2=\frac{m_2v_2}{\sqrt{1-(\frac{v_2}{c})^2}}

as momentum is conserved therefore P_1=P_2

8.219\times 10^{-28} kg c=\frac{1.51\times 10^{-27}\times v_2}{\sqrt{1-(\frac{v_2}{c})^2}}

v_2=0.478 c

storchak [24]
<span>θ=0.3sin(4t)
w=0.3cost(4t)(4)=1.2cost(4t)
a=-4.8sin(4t)

cos4t max will always be 1 (refer to cos graph), for same reason, sin4t will always be 0

therefore, wmax=1.2rad/s
 
vAmax=r*w=250*1.2=300mm/s
(may be different if your picture/radius is from a different picture)

adt=a*r=200*-4.8sin(4t)=0 (sin(4t)=0)

adn=r*w^2=200*1.2^2=288

ad= square root of adt^2+adn^2 = 288mm/s^2</span>
