Answer:
Please find the answer in the explanation
Explanation:
Take the regular compass and hold it so the case is vertical. Now use it to investigate the direction of the coil’s magnetic field at locations other than the central axis.
What happens as you move away from the center axis toward the coil? The direction of the magnetic compass needle will move in an opposite direction since the direction of the induced voltage is reversed.
What happens above the coil?
the needle on the magnetic compass will be deflected. Since compasses work by pointing along magnetic field lines
Outside the coil? The magnetic compass needle will experience no deflection. Since there is no induced voltage or current.
Below the coil?
The needle will move in an opposite direction.
Answer:
More energy
Explanation:
The amount of energy carried by a wave is related to the amplitude of the wave itself. In particular, the amount of energy carried by the wave is proportional to the square of the amplitude of the wave:
where
E is the energy
A is the amplitude
This means, for instance, that if the amplitude of a wave is doubled, the energy it carries increases by a factor 4.
Answer:
15000000 m
Explanation:
From the question,
Speed (S) = Distance(d)/Time(t)
S = d/t....................... Equation 1
Make d the subject of the equation
d = St..................... Equation 2
Given: S = 50 km/s = 50000 m/s, t = 5 minutes = 5*60 seconds = 300 seconds
Substitute these values into equation 2
d = 50000(300)
d = 15000000 m
Hence the skier travels 15000000 m

Answer: as mass increases, the wave nature of matter is less easy to observe.</h2>
At the beginning of the 20th century the French physicist Louis De Broglie proposed the existence of matter waves, that is to say that <u>all matter has a wave associated with it.</u>
In this sense, the de Broglie wavelength 
is given by the following formula:
(1)
Where:
is the Planck constant
is the momentum of the atom, which is given by:
(2)
Where:
is the mass
is the velocity
Substituting (2) in (1):
![\lambda=\frac{h}{m.v}[\tex] (3)As we can see, if we increase the mass, the wavelength decreases (because [tex]\lambda](https://tex.z-dn.net/?f=%5Clambda%3D%5Cfrac%7Bh%7D%7Bm.v%7D%5B%5Ctex%5D%20%20%3Cstrong%3E%20%283%29%3C%2Fstrong%3E%3C%2Fp%3E%3Cp%3E%3C%2Fp%3E%3Cp%3EAs%20we%20can%20see%2C%20%3Cstrong%3Eif%20we%20increase%20the%20mass%2C%20the%20wavelength%20decreases%20%3C%2Fstrong%3E%28because%20%5Btex%5D%5Clambda)
is inversely proportional to ).
Therefore, if the wavelength decreases the wave nature of matter is less easy to observe.
The other options are incorrect because:
a) as increases decreases and the particle nature matter becomes more evident
b) as decreases increases and the wave nature matter becomes more evident
c) There is also a relation between the wavelength and the energy 
:
So, as energy increases, the particle nature matter becomes more evident and the wave nature of matter becomes harder to observe
