You have a parallel circuit since it allows the electrons to travel in 2 paths, allowing the other light to stay lit.
This is a trick question. Since the planets are in orbit all the time the distance changes, which is because some planets orbit faster than others. I hope this helped at least a little bit.
Answer:
= 10.3 m/s
Explanation:
We can solve this exercise using the conservation of the moment; the system is formed by the knife and the target, with an isolated system the moment is conserved during the collision
Knife mass m = 22.5 g and its velocity v₁₀ = 39 m / s, the mass of white is M = 300 gr and its velocity is v₂₀ = -2.15 m / s
Before the crash
p₀ = m v₁₀ + M v₂₀
After the crash
= m v₁ₐ + 0
p₀ =
m v₁₀ + M v₂₀ = m
= (m v₁₀ + M v₂₀) / m
Let's calculate
= (0.0225 39.0 + 0.300 (-2.15)) / 0.0225
= 10.3 m / s
Answer:
When water from the dam passes through, the turbines spin. This creates electricity. Hydroelectric power is produced as water passes through adam, and into a river below. The morewater that passes through a dam, the more energy is produced.

Answer:
Explanation:
The collision is elastic as no frictional force exists .
Both momentum and energy will be conserved.
We shall apply velocity formula applicable in respect of elastic collision
m₁ and m₂ be mass of red and green T shirt player , u₁ and u₂ be their initial velocity , v₁ and v₂ be their final velocity
v₂ = (m₂-m₁)u₂ / ( m₁+m₂) + 2 m₁u₁ / ( m₁+m₂)
Given m₁ = 40 kg , m₂ = 60 kg , v₂ = 2 m /s , u₁ = ? , u₂ = 0
Put the values in the equation
2 = 0 + 2 x 40 x u₁ / ( 40 + 60 )
u₁ = 2.5 m /s .
Initial speed of red T- shirt .
