Answer:6v
Explanation:
Current=0.30A
Resistance=20ohms
voltage=current x resistance
Voltage=0.30 x 20
Voltage=6v
The correct answer is C) frequency.
In fact, the frequency is the number of wave crests (or pulses) per seconds. In our problem, the machine that produces the wave pulses two times per second, so this is exactly the frequency of the compression wave.
Answer:Radioactive
Explanation:
The radioactive nucleus is the one which does not has enough binding energy to hold the nucleus in a stable state and thus radiates either electron or proton to become a stable element.
A radioactive element is formed when after billions of years such as uranium and thorium. The stability of the nucleus depends upon the opposition of attractive and repulsive force among the nucleus.
They are poor conductors because they keep the heat trapped in one spot, while other materials like metal let the heat go through itself.
