Answer:
wavelength = 0.01 m
distance = 162.8 m
Explanation:
Given that;
Speed of sound in water = 1,480 meters per second
Frequency of ultrasound = 125KHZ
From=
v=λf
v= speed of sound
λ= wavelength of sound
f= frequency of sound
λ= 1,480 ms-1/125 * 10^3 Hz
λ= 0.01 m
From
v = 2x/t
where;
v= velocity of sound in water
x= distance traveled
t = time taken
x = vt/2
x = 1,480 ms-1 * 0.220 s/2
x= 162.8 m
Gravity is the force that attracts to bodies toward each other friction is the resistance from one thing to another
Answer:
Part a)
ZERO
Part b)
N = 10 turns
Explanation:
Part a)
As we know that transformer is used to change the input voltage into required output voltage
Here this input and output is considered only when it will change with time as the whole concept is based upon Faraday's law where we need to change the flux with time.
So if we have input Source is DC source then output voltage will be zero as there is no flux change
Part b)
As we know by the principle of transformer



so total number of turns in secondary coil must be 10
Answer:
When the head moves, fluid within the labyrinth moves and stimulates nerve endings that send impulses along the balance nerve to the brain. Those impulses are sent to the brain in equal amounts from both the right and left inner ear.
Explanation:
In a spark ignition engine, the fuel is mixed with air and then inducted into the cylinder during the intake process. After the piston compresses the fuel-air mixture, the spark ignites it, causing combustion. The expansion of the combustion gases pushes the piston during the power stroke.
