Answer:
a. chemical reaction
Explanation:
In both a dry and wet cell battery, electric currents are produced through chemical reactions.
Both cells are together called electrochemical cells.
- In these cells, chemical reactions produce an electric current.
- They are devices that converts chemical energy into electrical energy
- The reactions here are spontaneous redox reactions.
- This causes the current to flow on their own in the circuit.
Nitrogen is a crucially important component for all life. It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food.
Answer:
0.95 A
Explanation:
P = Power of bulb = 4 W
V = Voltage = 12 V
Power is given by
The connections are in Parallel
Equivalent resistance of these two bulb
Current from the source
The voltage drop is
Voltage drop is given by
The internal resistance is 0.95 A
I think so
I think in our atmosphere have mass
Answer:
C (1.07 metres)
Explanation:
wavespeed = frequency x wavelength
rearrange for wavelength
wavelength = wavespeed ÷ frequency
so 320 ÷ 300 = 1.07m (rounded)
