Answer:
Lighter
Explanation:
In practice, the lamp is powered by an AC voltage source which is connected in series with an inductive ballast in order to supply an approximately constant current to the lamp, rather than a constant voltage. This helps to provide a stable operation. The ballast is usually inductive rather than simply being resistive to maximize resistive losses.
As this lamp current tending to zero-current point and shadow cast by the sodium flame becoming lighter.
Answer:
Explanation:
mass per unit length ρ = .100 / 1.65 = .0606 . kg /m
length of wire L = 1.65 m
For fundamental frequency , the expression is as follows
n =
L = 1.65 , T = 16 n and m = .0606
n =
= 4.9 /s .
This is fundamental frequency .
other mode of vibration ( first three ) will be as follows
4.9 x 2 = 9.8 /s ,
4.9 x 3 = 14.7 /s .
Answer:
Explanation:
d = 42 meters
v = 12 m/s
t = ?
t = d/v
t = 42 / 12
t = 3.5 seconds. That's awfully fast.
it is B and i cant explain sadly because i dont even know why time doesnt flow backwards even though that would be cool. please mark brainiest
The answer is:
-when Jackhammer is a huge hammer used to breaking up the hard rocks and the hard materials to smaller pieces.
-and the metamorphic rocks are type of rocks which change to metamorphic rock by heating and high pressure so, the chemical and physical properties of the rock will be changed.
-and here in cause of using the Jackhammer there is no change in the chemical or physical properties of the original rock and no high temp(more than 200°C ) or high pressure to change to metamorphic rock . It is just a breaking up of the rock to small parts.
