Explanation:
Sodium is a chemical element with the symbol Na (from Latin "natrium") and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table. ... The free metal does not occur in nature, and must be prepared from compounds.
I believe it would be x because you are trying to find the width of the wave but i could be wrong
Answer:
344.8 Hz
Explanation:
The frequency of a wave is given by:
where
v is the speed of the wave
is its wavelength
Here we have
v = 793 m/s
Substituting into the equation, we find
The formula to use is the one that connects the acceleration,
the distance fallen, and the time spent falling:
Distance = 1/2 a T² .
You said 2.1 meters in 0.6 second .
2.1 m = 1/2 a (0.6 sec)²
Multiply each side by 2 : 4.2 m = a (0.6 sec)²
Divide each side by (0.6 sec)² = (4.2/0.36) m/s² = a
a = (11 and 2/3) m/s²
(about 19% more than Earth's gravity)
Voltage is given by the formula
V = IR (Ohms law)
where V is the Voltage
I is the current
and R is the Resistance
Here it is given that the current is I=11
Resistance is R =12
so plugging this in the formula
V = IR
V= 11 * 12
V= 132 Volts
So the Voltage for the given dryer is 132 Volts
