Answer:
The difference is between number of turns, Magnetic flux linkage has number of turns while Magnetic flux lacks it

Explanation:
N is number of turns
Answer:
Speed of the hawk, v = 40.4 m/s
Explanation:
It is given that,
Exact frequency of the female, f = 785 Hz
Observed frequency of female, f' = 890 Hz
Speed of sound, v = 343 m/s
Let v' is the speed of the hawk. It is based on the concept of Doppler's effect. We know that when the object approaches you, its speed is given by :


v' = 40.4 m/s
So, the speed of the hawk is 40.4 m/s. Hence, this is the required solution.
Answer:
a) acceleration = 5.75 g
b) acceleration = -20.5 g
Explanation:
Hi there!
The acceleration is the variation of the speed over time:
a (acceleration) = (final speed - initial speed) / time
a) The acceleration in the direction of the motion of Dr. Stapp is:
a = (282 m/s - 0 m/s) / 5.00 s = 56.4 m/s² * (1 g / 9.80 m/s² ) = 5.75 g
b) The acceleration opposite the direction of the motion of Dr. Stapp is:
a = (0 m/s - 282 m/s) / 1.40 s = -201 m/s² * (1 g / 9.80 m/s² ) = -20.5 g
Answer:
Kinetic energy is referred to the energy associated with movement and or motion, thus the only object that is moving would be A boat sailing across the ocean.
