Answer:
1. Lateral inversion is a phenomenon in which left appears to be right and vice versa. It is due to direction that light follows when it strikes a reflecting surface, generally a mirror.
These are the letters which don't show lateral inversion A,H,O,T,U
2. USES OF CONCAVE MIRROR
They are used as shaving mirrors to see a larger image of the face.
Dentists use concave mirrors to view large images of the teeth of the patients.
USES OF CONVEX MIRROR
It is is used as a rear view mirror in vehicles.
It is used as a vigilance mirror.
Answer:
The frequency is 
Explanation:
From the question we are told that
The frequency of the tuning fork is 
The beat period is 
Generally the beat frequency is mathematically represented as
The beat frequency is also represented mathematically as
Where 
is the frequency of the piano
So
Answer:
I = 0.25 [amp]
Explanation:
To solve this problem we must use ohm's law which tells us that the voltage is equal to the product of the current by the resistance.
V = I*R
where:
V = voltage [Volt]
I = amperage or current [amp]
R = resistance [ohm]
Since all resistors are connected in series, the total resistance will be equal to the arithmetic sum of all resistors.
Rt = 2 + 8 + 14
Rt = 24 [ohm]
Now clearing I for amperage
I = V/Rt
I = 6/24
I = 0.25 [amp].
The statement that motion is relative is an important concept in physics. The meaning behind this statement is that the motion of an object is relative to either the frame of reference of the observer, or to another distinct frame of reference.
