1, yeti hair is thick and strong
2, a warm blanket and a change of clothes
3, to circulate the heat around the house/room
1/Rt = 1/R1 + 1/R2 + 1/R3+ 1/R4+ 1/R5
1/Rt = 1/6+ 1/6+1/6+1/6+1/6
1/Rt = 5/6
Rt = 6/5
Rt = 1.2 ohm
so B is the answer
I have the same physics class , so the answer would be 0.6
v = speed of the source of sound or the train towards the listener or switchman = 40 m/s
V = actual speed of sound = 340 m/s
f = actual frequency of sound as emitted from source or the train = 1000 Hz
f' = frequency as observed by the listener or by switchman = ?
Using Doppler's law , frequency observed by a listener from a source moving towards it is given as
f' = V f /(V - v)
inserting the values
f' = 340 x 1000 /(340 - 40)
f' = 340 x 1000/300
Answer with explanation:
The given vectors in are reduced to their componednt form as shown
For vector A it can be written as
Similarly vector B can be written as
Hence The sum and difference is calculated as
The direction is given by
with positive x axis.
Similarly
The direction is given by
with positive x axis.
