Answer:The trail mix is a heterogeneous mixture.
Explanation: Heterogeneous mixture is a mixture of the same phase like sugar dissolved in water.
Trail mix involved physical objects, thus it is a mixture of peanuts, small fruits etc.
Answer:
1/3 times.
Explanation:
Let V₀ be the peak voltage .
IR ( rms ) = ( V₀ / √2 R )
R is value of resistance
IC = ( V₀ ωC / √2 )
( 1 / ωC is reactance of capacitance in ac circuit )
=
When frequency is tripled angular frequency will also be tripled
hence the ratio becomes 1/3 times.
A road with a positive cross slope is highest in the center
of the road.
The roads with Cross slopes are formed to provide the
drainage system so that water will run off from the surface. Due to this no
water stands on the roads, especially when there is heavy rain it is very
useful. It is a very important safety factor.
Ive passed several physics classes. What's your question?
frequency fapproach is heard by a passenger = 302.05 Hz
frequency frecede is heard by a passenger = 228.37433 Hz
Given :
speed of train to the ground = 30.0 m/s
frequency emitted by the train whistle = 262 Hz
speed of sound in air = 344 m/s
To Find :
(A) frequency fapproach (B) frequency frecede
Solution :
The frequency of approach is given by
f' = f <u>v + v(relative)</u>
v - v(air)
= 262x <u>344 + 18</u>
344 - 30
f' = 302.05 Hz
The frequency of approach is 302.05 Hz
The frequency of recede is given by
f' = f <u>v - v(relative)</u>
v + v(air)
= 262 x <u>344 - 18</u>
344 + 30
The frequency of recede is 228.37433 Hz
