Answer:
The statement is true
Explanation:
The complete question is
Light bends when it changes the medium because the dielectric permittivity of the material makes the path more hard to penetrate
True or False
Solution
The given statement is true as it is the dielectric permittivity of the material which does not allow light to pass through it easily.
The medium decrease the amplitude of light and hence induces change in direction without altering its velocity or frequency.
Answer:
Energy, same
Explanation:
From the law of conservation of energy, it states that the total amount of energy is the same before and after any energy transformation. Energy can't be created nor destroyed but can only be transformed from one state to another. In the process of transformation, some minor losses may occur due to friction.
Answer:
D- Used to power turbines and generators
Explanation:
The nuclear fission takes place inside the core comprises fuel assemblies. Hence the heat produced is used to power turbines and generators.
Hope it helps!
Answer:
Y
Explanation:
Y will produce the strongest magnetic force because the current intensity is medium and it has 50 turns in the wire. the number of turns will increase the force because the magnetic field will be more concentrated.
Have a great day :)
The image of the tree between the focus point F and the mirror moves behind the curved mirror. This is further explained below.
<h3>What is a mirror?</h3>
A smooth surface such as glass that reflects pictures In the mirror, the law of reflection says that when a ray of light is produced to fall on a reflecting surface, the reflected ray has its angle of reflection, the incident ray has its angle of reflection, and the reflected ray is normal to the surface at a point of incidence.
In conclusion, Behind the curved mirror, the image shifts.
