Which item(s) would be sufficient to make a circuit?
2 answers:
Explanation :
A circuit is the representation of the path of the flow of current. The circuit can be either closed or open.
When the switch is off the circuit is closed circuit and when the switch is not connected the circuit is open.
The items that are sufficient to make a circuit are as follows :
Voltage source like a battery. Resistors or electrical equipment like heater, motor etc. Other components can be ammeter, voltmeter, ac source, variable resistors etc.
Answer: A key, a conducting wire, a battery/cell , a resistance.
Explanation:
A circuit is a loop through which electric current flows. Thus, a conducting wire is essential.
An energy source is required-one which provides a potential difference across the two terminals. A cell or a battery can be used.
A key is required to open or close the circuit. Current flows only when the circuit is closed i.e. it forms a loop.
A component which is required to work - A resistance - A bulb or a motor etc.

Answer:
661.25, I believe!
Explanation:
KE = (1/2)(2.5)(23)^2
KE=(1.25)(529)
KE= 661.25
Explanation:
When a man falls on a hard cemented floor his momentum reduced to zero in a very short time and hurt the man. Whereas when a man falls on a heap of sand. As sand can compress, it takes longer time for the man to hit the ground (or hard surface)
