Answer:
okay so, An electric circuit is a closed loop through which current can actually flow. All electric circuits must have a voltage source, for example a battery, and a conductor, which is usually a wire.
how does it flow or how does .current flow in a circuit ? When a wire is connected to battery terminals which is electrons, electrons flow from negative to positive. Electrons have a negative charge in case you didnt know. they are repelled from the negative and attracted to the positive.
if this helped please mark this as brainliest!!! :)
Answer:
Mark me as barinlest
Explanation:
If you shine light of high enough energy on to a metal, electrons will be emitted from the metal. Light below a certain threshold frequency, no matter how intense, will not cause any electrons to be emitted. Light above the threshold frequency, even if it's not very intense, will always cause electrons to be emitted.

Answer:
The nervous system does depend on other systems visa versa.
Explanation:
They depend on each other because the brain needs nutrients given from the system and also the systems need the sensors from the nervous system.
Answer:
-0.8 m/s²
Explanation:
Acceleration is the slope of a velocity vs. time graph.
a = Δv / Δt
a = (0 m/s − 12 m/s) / (15 s − 0 s)
a = -0.8 m/s²
