1. f1 = Vs + Vbat Vs fO
2. f1 = Vs Vs - Vbat fO
3. f1 = Vs Vs + Vbat fO
4. f1 = Vs + Vbat Vs - Vbat fO
5. f1 = 2Vs Vs - Vbat fO
6. f1 = Vs - Vbat Vs fO
7. f1 = Vs - Vbat Vs + Vbat fO
8. f1 = fO
9. f1 = 2Vs Vs + Vbat fO
The observed frequency is
f= (V+Vr) × fO/ (V + Vs)
The speed of the sound is V = Vs
The speed of the receiver is Vr = O
The speed of the source
Vs = -Vbat where negative is the bat which is approaching the wall
Then the correct answer is
f1 = (Vs / (Vs -Vbat)) × fO.
Answer:
Explanation:
As we know that torque due to applied force is given as
here we know that
applied force is given as
now we will have
Answer:
60km/hrs
=60×1000
-------------------
60×60
= 60000
-----------------
3600
= 16.66m/sec

Answer:
A)Temperature at which liquid starts to become gas.
Explanation:
Boiling point is the temperature at which a liquid boils and turns to vapour or gas.
From the law's of physics, we can know about the different boiling points for different liquids. As an example: at 100 °C temperature the water starts to change into the vapor. It's the boiling point of the water.
