Nebulas, because nebulas contain the gas needed to form a star and comets/planets/ asteroids are rocks not gas
Answer:
1 L = 1000 cm^3
1 m^3 = 1000 L = 10^6 cm^3
1 m^3 = 10^6 g = 10^3 kg density of water
M = Density * Volume
V = 2 * 4 * 5 = 40 m^3
M = 10^3 kg / m^3 * 40 m^3 = 4.0 * 10^4 kg
Elements are made of atoms, which are particles that represent the most basic form of an element.<span> An atom is the smallest particle of an element and cannot be further divided without becoming a less complex particle; in fact, the word 'atom' comes from the Greek word "atomos," meaning 'indivisible'.</span>
Explanation:
The sum of the voltages of the components connected in a series circuit is equal to the voltage across the battery.
From Ohm's law () and in a series circuit, the amount of current flowing through the components is the same for all. So we can write as
Answer:
Explanation:
easy way
when system is all kinetic energy, velocity is at a maximum
E = ½mv²
v = √(2E/m) = √(2(25)/0.5) = √100 = 10 m/s
harder way
ω = √(k/m) = √(80/0.5) = √160 rad/s
When the system is entirely spring potential, the amplitude A is
E = ½kA²
A = √(2E/k) = √(2(25)/80) = 0.790569... = 0.79 m
maximum velocity is ωΑ = 0.79√160 = 10 m/s
