Answer: B. 0.6125 m

For spherical concave mirror:

Height of the object, h_o=0.4\hspace{1mm}m

Height of the image, h_i=0.35\hspace{1mm}m

Object distance, u=-0.7 m

we need to find the distance of the image, v.

These are related by the following formula:

\frac{h_i}{h_o}=-\frac{v}{u}\\ \Rightarrow v=u\times\frac{h_i}{h_o}

Insert the values:

v=-(-0.7\times\frac{0.35}{0.4})=0.6125\hspace{1mm}m

Hence, option B is the correct.

yarga [219]

Answer:

E) are electrically attracted to each other

Explanation:

Water molecule is polar because there is a difference in electronegativity values between hydrogen and oxygen. The hydrogen side of the molecule has a slight positive charge and the oxygen side is slightly negatively.  

Positively and negatively charged ends cause water molecules to attract one another and for this reason water shows the properties mentioned in the question: cohesion, high specific heat, and high heat of vaporization.
