Answer:
f = 293.38 Hz
1 st overtone = 586.76 Hz
2 nd overtone = 880.14 Hz
Explanation:
Mass of the string, m =3.4 g = 0.0034 kg
Length of the string, l = 90 cm = 0.90 m
Distance from the bridge, L = 62 cm = 0.62 m
Tension in the string, T = 500 N
Fundamental frequency is given by:
First overtone = 2 × f = 2 × 293.38 =586.76 Hz
Second Overtone = 3×f = 3 × 293.38 = 880.14 Hz
Answer:
A
Explanation:
and that is a very strange question in physics ...
it actually depends on what state you are in.
California for example requires all to stop unconditionally, I think. while in many other states it is the rule, if the 4-lane road is separating both driving direction by a barrier or raised intermediate area, you don't have to stop when going in the opposite direction.
so, it is either A or D depending on your state.
B and C never apply.
<u>Answer</u>:
Yes, there are differences between supersonic planes and concorde planes
<u>Explanation</u>:
The supersonic planes moves faster than the speed of sound. But these flights are banned because it is economically non-starter. It has more loud sound equivalent to the explosion. The banned was elevated in 2003, due to new aviation law. The concords travel twice the speed of sound. This planes holds the record for the fastest planes but seen to be fleet long back i.e. in 2003. These were banned when a fatal crash had been reported. And now are only found in the museums.
The current decreases as the overall resistance increases. In addition, if one bulb is removed from the “chain” the other bulbs go out. ... If light bulbs are connected in parallel to a voltage source, the brightness of the individual bulbs remains more-or-less constant as more and more bulbs are added to the “ladder”.
