<u>Answer</u>
1 1/3 m/s
<u>Explanation</u>
The momentum before collision and after collision is always conserved.
m₁v₁ = m₂v₂
(0.05×0.6) + (0.03×0) = (0.03 × v) + (0.05 × -0.2)
0.03 + 0 = 0.03v - 0.01
0.03v = 0.03+0.01
0.03v = 0.04
v = 0.04/0.03
= 4/3
= 1 1/3 m/s
They were able to find the orbit of a comet and predict the year of its return.
Answer:
its either kinetic or potential energy
Answer:
A or B you choose
Explanation:
This is called current electricity or an electric current. A lightning bolt is one example of an electric current, although it does not last very long. Electric currents are also involved in powering all the electrical appliances that you use, from washing machines to flashlights and from telephones to MP3 players.
what is an electrical current, amp, ampere Current is the flow of electrons. When a circuit is closed then a current of electrons can flow and when a circuit is open then no current can flow. We can measure the flow of electrons just like you can measure the flow of water through a pipe.
