1. In a biology experiment the number of yeast cells is determined after 24 hours of growth at different temperatures.
a) Identify the independent and dependent variables in the experiment.

Find the answer in the explanation

Explanation:

Given that In a biology experiment the number of yeast cells is determined after 24 hours of growth at different temperatures

The dependent variable depends on the value of the independent variable.

From the question above,

The independent variable is the temperature

While the dependent variable is the number of yeast cells

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.
