2. A simple hydraulic lift is made by fitting a piston attached to a handle into a 3.0-cm diameter cylinder. The cylinder is connected to a larger cylinder with a 24-cm diameter. If a 50-kg woman puts all her weight on the handle of the smaller piston, what weight could the other piston lift? Could the woman lift a large car with a weight of 1.6104 N?

mparing this value with the weight of the vehicle we see    W₂> 1.6 10⁴ N

therefore the woman can lift the car

Explanation:

For this exercise on Pascal's principle, we use that the pressure in every incompressible liquid is the same

         P₁ = P₂

   the press is defined by

         P = F / A

for the woman's side

  the area of a circle is

         A = π D₁² / 4

         P₁ = W (4 /π d₁²)

for the car side

         A₂ =π d₂²

        P₂ = W₂ (4 /π d₂²)

we substitute in the first equation

         W (4 /π d₁²) = W₂ 4 /π d₂²)

          W / d₁² = W₂ / D₂²

           W₂ = (d₂ / d₁)² W

the weight of the woman is

           W = mg

we calculate

          W₂ = (24/3)₂ 50 9.8

          W₂ = 3,136 10⁴ N

when comparing this value with the weight of the vehicle we see

          W₂> 1.6 10⁴ N

therefore the woman can lift the car

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.
