Here we go ~

❖ Qualitative data determines the property or characteristics of certain object or behavior.

❖ Quantitative data determines the number or quantity of a substance. basically dealing with how much/many things are being used.

Now let's move on to questions ~

#1. Carbon is a organic molecule.

- Qualitative

#2. The forest is 25% oak trees.

- Quantitative

#3. Water contains covalent bonds.

- Qualitative

#4. Sheila's blood pressure is 120/80.

- Quantitative

#5. The bat arm and human arm have similar bone structure

- Qualitative

Your friend decides to generate electrical power by rotating a 100,000 turn coil of wire around an axis in the plane of the coil

MakcuM [25]

Answer:

a) I=35mA

b) P=1.73W

Explanation:

a) The max emf obtained in a rotating coil of N turns is given by:

$emf_{max}=NBA\omega$

where N is the number of turns in the coil, B is the magnitude of the magnetic field, A is the area and w is the angular velocity of the coil.

By calculating A and replacing in the formula (1G=10^{-4}T) we get:

$A=\pi r^2 =\pi(0.23m)^2=0.16m^2$

$emf_{max}=(100000)(0.3*10^{-4}T)(0.166m^2)(140\frac{rev}{s})=69.72V$

Finally, the peak current is given by:

$I=\frac{emf}{R}=\frac{69.72V}{1400\Omega}=49.8mA$

we have that

$I_{rms}=\frac{I}{\sqrt{2}}=\frac{0.0498A}{\sqrt{2}}=0.035A$

$P_{rms}=I^2{rms}R=(0.035A)^2(1400\Omega)=1.73W$

hope this helps!!
