Explanation:
100%
Answer:
4. total energy
Explanation:
According to Bernoulli's principle at any two points along a streamline flow The total energy that is sum of pressure energy , Kinetic energy and potential energy of the liquid all taken in per unit volume remains constant. Therefore,
for ideal fluid flows through a pipe of variable cross section without any friction. The fluid completely fills the pipe. At any given point in the pipe, the fluid has a constant Total Energy.
Answer:
Detailed explanation:
Density of water=1000kg/m³
Hence mass of water displaced is:
m=d×v
=1000kg/m³×(4.3×10^-3)m³ (volume of water displaced converted to L)
=4.3 kg of water
Hence, mass of football is also 4.3 kg(Archimedes principle)
Thus density of football
=mass÷volume
substitute the mass and volume and solve.

Explanation:
The magnetic field inside a solenoid is given by the following formula:

where,
B = Magnetic Field Inside Solenoid
μ₀ = permittivity of free space
n = No. of turns per unit length
I = Current Passing through Solenoid
For Solenoid 1:

For Solenoid 2:
n₂ = 6n₁
Therefore,

Diving equation 1 and equation 2:

Hence, the correct option is:
