The answer is true because A current carrying wire is surrounded by magnetic field
Answer:
3.48076 m
Explanation:
= Pressure difference = 35 kPa
= Density of water = 1025 kg/m³
g = Acceleration due to gravity = 9.81 m/s²
h = Depth of water
Pressure difference is given by
The depth at which this pressure difference occurs is 3.48076 m
Answer:
0.85V
Explanation:
The emf is calculated by using the Lenz's Law
But for this case we have that the magnetic field is constant. Hence we have
where we have taken that the intial time is t1=0
I hope this is useful for you

The length of the leg is approximately the height of the person:
The period is:
Answer:
The sun heats the earth through radiation. Since there is no medium (like the gas in our atmosphere) in space, radiation is the primary way that heat travels in space. When the heat reaches the earth it warms the molecules of the atmosphere, and they warm other molecules and so on.
