d
Explanation:
With gases they escape into the atmosphere so u cant move it around withoulosing some. With liquids sometimes they get spilled or little bit gets left at the bottom of the original container
Answer:
Option D, both A and B
Explanation:
The potential difference is created across a battery (between its two terminal –one positive and the other one negative) when work is done to move a charge from one point to another. This potential difference is measured in volts. 1 volt is the potential difference between two points when one joule of potential energy is spent to move a charge of one coulomb from one point to the other.
Voltage drop across a circuit is the amount of electric current lost due to resistance/ impedance with in the cables of the circuit.
Hence, both potential difference and voltage drop occurs across the circuit,
Option D is correct.
Answer:
b
Explanation:
I looking at the electro magnetic spectrum I can tell scientists if things are moving toward the Earth or away from the Earth
