210 Pb ---> -ie + 210 B:
84 8.3
Answer:
1210 ohm
Explanation:
Given :
P=40 W
V=220 V
Now,
Therefore, resistance of bulb will be 1210 ohm
A high electromagnetic wave has short, very fast, frequent waves.
a low electromagnetic wave has long, very slow, infrequent waves.
hope this helps! pls mark brainliest!
The speed of sound through air at room temperature is almost always 343 m/s. However, since it doesn't tell you that, use the equation wavelength=velocity/frequency. Plug in the numbers: 1.4=v/247, and v=345.8 m/s.
"Free fall" means that gravity is the ONLY force acting on the object. If there's air resistance, then it isn't free-fall.
Objects that fall near earths surface are ALWAYS falling through air, unless they're inside some kind of a vacuum chamber with all the air removed from it.
