F = focal lenght = 67.1 cm
u= distance between mirror and object = 16.76 cm
1/f = 1/v + 1/u
1/67.1 = -1/16.76 + 1/u
1/67.1 + 1/16.76 = 1/u
u = 13.41

Answer:
The answer is 3; Zero
Explanation:
It is to remembered that at critical temperature all three phases of liquid are at equilibrium and the surface tension is zero at this temperature.
Answer: Metallic bond
Metallic bond can be defined as a force of attraction that
exit between a metal atoms and the velency eletron. Also, this bond arise from
the electostatic force of attraction that between conduction electrons and
positively charged metal ions. Thus, the electron usually act as a glue by giving
the substance a definite structure.
1. Statement A is true.
When GTP is hydrolysed, the free energy of hydrolyses is used to power or drive reactions that are favourable energetically.
2. Statement B it true.
ATP is a complex chemical that gives energy for the activities in many living cells. During hydrolyses, chemical energy stored in the energy-rich phosphoanhydride is released. Hence its a common source of chemical energy in cells.
3. Statement C is false.
The hydrolyses of ATP to ADP in the presence of phosphate, releases one mole of ATP which is estimated to be -57Kj/mol not 14Kj/mol. Below is the equation;
ATP + H20 -----> ADP + Pi + Free energy.
4. Statement D is false.
GTP stands for guanosine triphosphate.
ATP stands for adenosine triphosphate
ADP stands for adenosine diphosphate.
