Answer:
On average a galaxy has, between <u>800 billion and 3.2 trillion planets.</u>
Answer:
5.69 m/s.
Explanation:
The given data is as follows.
Magnetic field strength (B) = 0.65 T
Speed (v) = 4.2 m/s
Induced emf (E) = ?
Formula for emf induced at the ends of the rod of length L which is moving with a speed of v is as follows.
E = BvL
Putting the given values into the formula as follows.
.
When magnetic field is changed to
Now, we assume that the speed be to get the emf
Then,
we can conclude that the speed v of the rod be adjusted to reestablish the emf induced between the ends of the rod at its initial value is 5.69 m/s.
Answer
D.Diffraction
Explanation
Diffraction is a property that is experienced by waves when they come across a barrier when they are in motion.
The ways tends to curve behind the barrier. This is called diffraction of waves.
Now, sound is a wave and it also experience diffraction. . So the brother will be able to hear the sound due to diffraction
