Answer:

The Adam's apple, in relation with the THYROID CARTILAGE which forms it, helps protect the walls and the FRONTAL PART of the larynx, including the VOCAL cords (which are located directly behind it). Another function of the Adam's apple is related to the deepening of the voice.

Answer:

A STRING is STRETCHED by two equal and opposite forces the tension in the string is

The string is in EQUILIBRIUM(a=0)because it is pulled by two equal forces of 10N. Let us DIVIDE the string in two parts Left part and Right part. By definition, Tension is force of interaction between one part and another part. That means the left part is pulling the right part with a force T in the left direction.

ANSWER:

DISTANCE = SPEED /TIME taken

Explanation:

speed =400

time=26

Distance= speed /Time

so,,.

Explanation:

ACCORDING to the Harvard STEP test,

PHYSICAL fitness Index of runner

= 100 x Test DURATION (in sec) / 2 x no. of heartbeats during the process of regaining health

Total no. of heartbeats = 85+ 75 + 60 = 220

Physical Fitness index = 100 x 300 / 2 x 220 = 68.18

Explanation:

Observe from rows 2 and 3 that a doubling of the mass results in a halving of the acceleration (if force is held constant). And similarly, rows 4 and 5 show that a halving of the mass results in a doubling of the acceleration (if force is held constant). Acceleration is inversely PROPORTIONAL to mass.

Explanation:

Properties of Bar magnet:-

☞It has a north pole and a south pole at two ends. EVEN if you break a bar magnet from the middle, both the pieces will still have a north pole and a south pole, no matter how many pieces you break it in.

☞Properties of Bar Magnet

The magnetic force of it is the strongest at the pole.

☞If this magnet is suspended FREELY in the air with a thread, it will not come to rest until the poles are aligned in a north-south position. A Mariner’s COMPASS uses this property to determine direction.

☞If two bar magnets are placed close to each other, their unlike poles will attract and LIKE poles will repel each other.

☞A bar magnet will attract all ferromagnetic materials such as iron, nickel and cobalt.

ANSWER:

An order of magnitude is an APPROXIMATE measure of the number of digits that a number has in the commonly-used base-ten number system. It is equal to the whole number FLOOR of logarithm (base 10). For EXAMPLE, the order of magnitude of 1500 is 3, because 1500 = 1.5 × 103.

Atomic size GRADUALLY decreases from LEFT to right ACROSS a period of elements. This is because, WITHIN a period or family of elements, all ELECTRONS are added to the same shell.

Answer:

The scalar product of ORTHOGONAL vectors vanishes; the scalar product of antiparallel vectors is negative. The vector product of two vectors is a vector PERPENDICULAR to both of them. Its MAGNITUDE is obtained by MULTIPLYING their magnitudes by the sine of the angle between them.

ELECTRIC flux, property of an electric FIELD that may be thought of as the number of electric lines of FORCE (or electric field lines) that intersect a GIVEN area. Electric field lines are considered to originate on positive electric charges and to TERMINATE on negative charges.

ANSWER:

PROPORTIONAL to x^2.

As we know TOTAL energy of pendulum is CONSTANT i.e 1/2KA^2=1/2mw^2A^2=1/2mw^2x^2.

MOSQUITOES cause more human suffering than any other organism. Mosquito acts as a VECTOR for the BACTERIA and viruses, responsible for the DISEASES such as malaria, dengue, encephalitis and yellow fever ETC

Second law of motion :

The rate of change of momentum is directly proportional to the applied force and takes place in the direction in which the force acts.

➞ Force ∝ Change in momentum ÷ TIME taken

➞ F ∝ mv - mu/t

➞ F ∝ m(v - u)/t

➞ F ∝ ma

➞ F = k × m × a

Where,k is constant.

➞ k = F/ma

➞ k = 1 N/1 kg × 1 m/s²

➞ k = 1

➞ F = 1 × m × a

➞ F = ma

Hence,proved.

First law of motion :

A body at rest will REMAIN at rest and a body in motion will continue in motion in a straight LINE with uniform speed,unless it is compelled by an external force.

Third law of motion :

To EVERY action there is an equal and OPPOSITE reaction.

ANSWER :

If the velocity is variable and depends on time time t, to FIND the AVERAGE value of velocity for time interval t = t₁ to t = t₂

v = vsinωt

t = t₁ = T/2

t = t₂ = 0

Answer:

For girls, puberty usually starts AROUND age 11. But it can start as early as age 6 or 7. For boys, puberty begins around age 12. It can start as early as age 9.Adrenarche is usually NORMAL in girls who are at least 8 years OLD, and boys who are at least 9 years old. Even when pubic and underarm hair appear in children YOUNGER than this, it is still usually nothing to worry about, but your child does need to see their pediatrician for an exam.

ok BRO your QUESTIONS is very important so i am definitely GIVE you answer in 2 MIN

GIVEN :

• Force, F = 5 N

• Mass, m = 10 kg

To find :

• Acceleration, a

According to the question,

➞ Force = Mass × Acceleration

Or,

➞ F = ma

➞ Substituting the VALUES,

➞ 5 = 10 × a

➞ 5 ÷ 10 = a

➞ 0.5 = a

So,the acceleration is 0.5 m/s².
