By conservation of momentum,
Distance lighter fragment slide= 7*6.7=46.9m
Answer:
f=15.5 Hz
Explanation:
Let's determine the internal resistance:
ρ = 1.68*10^-8 Ω m
Ω
Since the bulb is rated at 12.0 V and 25.0 W,
Current
Therefore, voltage drop inside generator =
Actual EMF required is
Note that this is an RMS value.
The peak voltage is
For a generator, by Faraday's Law,
*ω
ω
f=ω/(2π)=
f=144.5 rad/s/(2π)
f=23.001 Hz
This is a concrete example of the Doppler effect. This effect is the change of frequency experienced by the listener or the observer with respect to their relative distance to the source of the sound. There can be two equations to be applied: to the approaching source, and to the receding source.
Approaching source:
frequency observed = [v/(v-v,source)]*frequency of source, where v is the velocity of sound . Substituting,
1000 = [340/(340-v,source)]*frequency of source <---- equation 1
Receding source:
frequency observed = [v/(v+v,source)]*frequency of source, where v is the velocity of sound . Substituting,
800 = [340/(340+v,source)]*frequency of source <---- equation 2
Rearranging equation 1: [1000(340-v,source)]/340 = frequency of source
Equation 2: 800 = [340/(340+v,source)]*frequency of source
Substituting equation 1 to equation 2:
800 = [340/(340+v,source)]*[1000(340-v,source)]/340
Solving using the scientific calculator under shift-solve feature,
v,source = 37.78 m/s
Therefore, the train is moving at 37.78 m/s.
The type of relationship formed when a megabat eats a fig and drops the seeds in a new location is COMENSALISM. It is an ecological interaction.
<h3>What is commensalism?</h3>
Commensalism is a type of ecological interaction in which one organism benefits (in this case, the tree) and the other organism neither benefits nor harm (the megabat).
Mutualism is a type of ecological association in which both organisms benefit from such interaction.
Conversely, parasitism is a type of ecological interaction in which one organism benefits and the other organism is harmed.
