Dear Students/Parents
APEX INSTITUTE has been established with sincere and positive resolve to do something rewarding for ENGG. / PRE-MEDICAL aspirants. For this the APEX INSTITUTE has been instituted to provide a relentlessly motivating and competitive atmosphere.
We at 'Apex Institute' are committed to provide our students best quality education with ethics. Moving in this direction, we have decided that unlike other expensive and 5star facility type institutes who are huge investors and advertisers, we shall not invest huge amount of money in advertisements. It shall rather be invested on the betterment, enhancement of quality and resources at our center.
We are just looking forward to have 'word-of-mouth' publicity instead. Because, there is only a satisfied student and his/her parents can judge an institute's quality and it's faculty members coaching.
Those coaching institutes, who are investing highly on advertisements, are actually, wasting their money on it, in a sense. Rather, the money should be invested on highly experienced faculty members and on teaching gears.
We all at 'Apex' are taking this initiative to improve the quality of education along-with each student's development and growth.
Committed to excellence...
With best wishes.

This guideline is directed principally toward new Molecular Entities that are
likely to have significant use in the elderly, either because the disease intended

because the population to be treated is known to include substantial numbers of
geriatric patients (e.g., hypertension).
Are you looking for a long-lasting solution to your missing tooth?
Dental implants are the most common type of method for replacing the missing tooth. Unlike dentures or bridges, implants are surgically placed in the jawbone. In layman’s terms, a dental implant is similar to the natural root of the tooth. It offers a stable foundation for the artificial tooth giving it the look, feel, and function similar to the natural tooth.
5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.

car includes two parts :

has seen a danger and before the brakes are on).
2. the braking distance s (i.e. the distance travelled after the brakes
have been put on).

the car travelled a distance of 19.7 m before coming to rest. You
may neglect the change in speed of the car during the impact.

12. 9. Yunnan Guoqiao-mixian (雲 南 過 橋 米 線 ) is a famous Chinese food. In
preparing the food, the first step is to cook a pot of chicken soup : A pot of
water containing chickens is heated over a high flame until it boils. A low
flame is then used to keep the soup boiling for 3 hours.
(a) Explain why the temperature of the boiling soup remains
unchanged, even though it is being heated.
(2 marks)
(b) (i) The power output of the low flame is 300 W. If 70% of
the energy supplied is lost to the surroundings, calculate
the mass of soup that would be vaporized after being
heated for 3 hours. Assume the specific latent heat of
vaporization of the soup is 2.26 × 106 J kg–1.
(3 marks)
(ii) Explain why it is undesirable to use a high flame to keep
the soup boiling.
(1 mark)
(c) Customers ordering the food are served with the following :
a bowl of hot soup with a layer of oil on the surface,
a dish of thin slices of raw meat, and
a bowl of pre-cooked mixian (noodles) (see Figure 14).

Mass of each slice of meat = 0.02 kg
Initial temperature of the meat = 27°C
Specific heat capacity of the meat = 3500 J kg–1 K–1
For health reasons, the meat has to be heated to a
minimum temperature of 82°C. Estimate the maximum
number of slices of meat that can be added to the soup.
State one assumption in your calculation.

131
is a radioisotope which decays by emitting a β-particle
Iodine-131 53
and γ rays. It is used in hospitals to test the kidneys of patients. During the
test, an iodine-131 solution is injected into the bloodstream of a patient. As
the blood passes through the kidney, iodine-131 will be absorbed by the
kidney and eventually excreted out of the body with urine. If the kidney is
not functioning properly, both the absorption and excretion rates of iodine-
131 will decrease. A γ -detector is placed near the kidneys of the patient to
detect the activity of the radiation coming from the kidneys (see Figure 15).
(a) Using X to denote the daughter nucleus, write down an equation
for the decay of an iodine-131 nucleus.
(2 marks)
Explain why the β-particles emitted by iodine-131 fail to reach the

detector.

(c) The half-life of iodine-131 is 8 days.
(i) State the meaning of ‘half-life’.
(2 marks)
(ii) For safety purposes, the activity of iodine-131 solution in
the test should not exceed 1.5 × 108 disintegrations per
second. When an iodine-131 solution is prepared, its
activity is 6 × 108 disintegrations per second. How many
days after preparation would the solution be suitable for
the test ?

radioisotope which is also used in the kidney test.

rays and the image formed. (4 marks)
(ii) Find the magnification of the image formed. (2 marks)
(b) Suggest one reason to explain why the concave lens inside the
peephole cannot be replaced by a convex lens. (2 marks)
(c)
Figure 19 shows the top-view of the peephole. The metal tube will

Now a visitor stands at a point P and Kitty cannot see him through
the peephole.
(i) Explain, by drawing a ray diagram in Figure 20, why
Kitty cannot see the visitor. (3 marks)
(ii) The lens is now replaced by another concave lens of a

length of this lens. (4 marks)
