neutral objects is correct
Answer:
The value is 
Explanation:
From the question we are told that
The distance of the speaker from the second speaker to the east is
The distance of the speaker from the listener to the south is 
Generally given that if the speaker move in any direction, their sound become louder , it then mean that the position of the listener of minimum sound (i.e a position of minima ) ,
Generally the path difference of the sound produce by both speaker at a position of minima is mathematically represented as
Generally considering the orientation of the speakers and applying Pythagoras theorem we see that distance from the second speaker to the listener is mathematically represented as

=> 
=> 
Generally the path difference between the two speaker with respect to the listener is
=>
=> 
So
=> 
Answer:
=0.855V
Explanation:
The induced voltage can be calculated using below expression
E =B x dA/dt
Where dA/dt = area
B= magnetic field = 6.90×10-5 T.
We were given speed of 885 km/h but we will need to convert to m/s for consistency of unit
speed = 885 km/h
speed = 885 x 10^3 m/hr
speed = 885 x 10^3/60 x60 m/s
speed = 245.8 m/s
If The aircraft wing sweep out" an area
at t= 50.4seconds then we have;
dA/dt = 50.4 x 245.8
= 123388.32m^2/s
Then from the expression above
E =B x dA/dt substitute the values of each parameters, we have
E = 6.90 x 10^-5 x 12388.32 V
E =0.855V
Hence, the average induced voltage between the tips of the wings is =0.855V
Answer:
“Global baking is a progressive increase in the earth’s hotness mainly on account of the dirtiness precipitated by raised levels of colorless odorless gas, CFCs, and additional contaminants. “
Causes and effects:
Global Warming is A Huge Problem for Our Planet, Threatening Biodiversity, Weather Patterns, and Human Health
Since the question above is looking for the SPEEd of the WAVE, the formula that should be used is SPEED = DISTANCE / TIME. You just need to substitute the distance (36 meters) and the time (15 seconds) to the formula. You should be able to get SPEED = 2.4 m/s.
