Answer:
(a) 1.414 km
(b) 1.06 m/s
Explanation:
(a) For John:
Distance = 1 km north and then 1 km east
Speed = 1.5 m/s
total distance traveled = 1 + 1 = 2 km = 2000 m
Time taken to travel = Distance / speed
t = 2000 / 1.5 = 1333.3 seconds
Displacement = 
(b) For jane :
Time is same as john = 1333.33 second
Distance = 1.414 km = 1414 m
Speed = distance / time = 1414 / 1333.33 = 1.06 m/s
Answer:
0.173 m.
Explanation:
The fundamental frequency of a closed pipe is given as
fc = v/4l .................. Equation 1
Where fc = fundamental frequency of a closed pipe, v = speed of sound l = length of the pipe.
Making l the subject of the equation,
l = v/4fc ................ Equation 2
also
v = 331.5×0.6T ................. Equation 3
Where T = temperature in °C, T = 18.0 °c
Substitute into equation 3
v = 331.5+0.6(18)
v = 331.5+10.8
v = 342.3 m/s.
Also given: fc = 494 Hz,
Substitute into equation 2
l = 342.3/(4×494)
l = 342.3/1976
l =0.173 m.
Hence the length of the organ pipe = 0.173 m.
Answer:
4.06 Hz
Explanation:
For simple harmonic motion, frequency is given by
where k is spring constant and m is the mass of the object.
Substituting 0.2 Kg for mass and 130 N/m for k then

In simple words, flux can be stated as the rate of flow of a fluid, radiant energy, or particles across a given area.
<u>Explanation:</u>
<u>Mutual Flux:</u>
- The magnetic lines present in among two magnets or solenoid is mutual flux.
- These are the lines in which the attraction and repulsion happens.
- The SI unit of mutual flux is the Henry
<u>Leakage Flux:</u>
- In simple words, it can be stated as the magnetic flux which does not follow the specially designed way in a magnetic circuit.
- Leakage flux in the induction motor takes spot due to current runs through the essence of the induction motor.
- The SI unit of Leakage flux is the Weber
<u>Magnetizing flux</u>
- Magnetic flux is an analysis of the entire magnetic field which moves in a given field
- In simple words can be defined as the Magnetic flux is what generates the field around a magnetic material.
- The SI unit of magnetic flux is the Weber
