<span>The question is asking for the reason why water is considered a polar molecule. The correct option is A. Water molecule is a polar molecule because it has one side which is positively charged and the other side is negatively charged. Each molecule of water has two hydrogen atom and one oxygen atom. The slight negative charge near the oxygen atom attract nearby hydrogen atoms from water and the slightly positive charge of the hydrogen atom attract oxygen atom. The attraction set up by these charges are responsible for the polarity of water molecules. </span>

The tomato is dropped. What is the velocity, v, of the tomato when it hits the ground? Assume 85.6 % of the work done in Part A
IRISSAK [1]

Answer:

v = 4.1 \sqrt{h}

Explanation:

Let the mass of tomato is m and the height from which it falls is h.

Let the tomato its the ground with velocity v.

The potential energy of the tomato at height h

U = m x g x h

The kinetic energy of tomato as it hits the ground

K = 1/2 mv^2

According to the question,

85.6 % of Potential energy = Kinetic energy

\frac{85.6}{100}\times m\times g\times h = \frac{1}{2}\times m\times v^{2}

v = 4.1 \sqrt{h}

A typical human lens has an index of refraction of 1.430 . The lens has a double convex shape, but its curvature can be varied b
rjkz [21]

Answer:

Maximum Power = 144.3 D

The associated focal length of the lens = 6.92*10^{-3} m

Explanation:

According to the Lens maker's Formula:

\frac{1}{f} = (n-1) (\frac{1}{R_1}-\frac{1}{R_2}  )

where;

n_1 = the refractive index of the medium

R_1 and R_2 = radius of curvature on each surface

For a convex lens, The radius of curvature in the front surface will be positive and that of the second surface will be negative . Therefore;

\frac{1}{f} = (n-1) (\frac{1}{R_1}-\frac{1}{-R_2}  ) \\ \\ \frac{1}{f} = (n-1) (\frac{1}{R_1}+\frac{1}{R_2}  )

At maximum power

\frac{1}{f} = (1.430-1) (\frac{1}{6.50 \ mm}-\frac{1}{5.50 \ mm}  )

= 0.144 \ mm^{-1}

This Implies

f = 6.92 mm\\f = 6.92*10^{-3} \ m

Therefore; the power is given by the formula:

P_{max} = \frac{1}{f}

P_{max}= \frac{1}{6.92*10^{-3}}

= 144.3 D
