EXPLANATION:

APPROACH: To calculate the area of the leaf, first find the area of the half leaf AECA, which can be given as: Area of half leaf = Area of quadrant AECDA – Area of right triangle ACD. Thus, Area of half leaf = ( PI * a * a / 4 ) – a * a / 2 where PI = 22 / 7 and a is the side of the square

from time 2 - 3S slope is INCREASE so in a-t graph a is 3 m/s^2,in time 3-6 V is constant so a is 0 from time 6-8 the slope is -ve so a is -1.5

hope it's help u plzz thank my answers...

EXPLANATION:

A black hole is an extremely dense object in space from which no light can escape. While black holes are MYSTERIOUS and exotic, they are also a key consequence of how gravity works: When a lot of mass gets compressed into a small enough space, the resulting object rips the very fabric of space and TIME, becoming what is called a singularity. A black hole's gravity is so POWERFUL that it will be able to pull in nearby material and "eat" it.

EXPLANATION:

If a positive charge is MOVING in the same direction as the electric field vector the particle's velocity will INCREASE. If it is moving in the opposite direction it will decelerate. If a negative charge is moving in the same direction as the electric field vector the particle will decelerate.

ong>Answer:

1. It takes some time to see objects in a dim or DARK room when we enter the room from the bright sunlight outside because in bright sunshine the pupil of our eye is small. Hence, as we enter a dim room, very LITTLE light enters our eyes and we can't see properly.

2. We need two eyes because a human being has a horizontal field of view of about 150° with one eye and of about 180° with two eyes. Thus, two eyes provide US wider horizontal field of view. With one eye, the world looks flat, i.e., two dimensional only.

Thomson referred to electrons as 'corpuscles'. ... In 1907 Thomson BEGAN to investigate the rays that were MOVING towards the cathode. These rays were positively charged, and Thomson wanted to see if they were ALSO composed of charged particles. The POSITIVE rays had first been observed by Goldstein in 1886.

i just WANTED to CORRECT your spelling- it is not attracte it is ATTRACT

Explanation:

Q2 ) mass is directly proportional to the GRAVITATIONAL energy possessed by the body. since earth has a BIGGER mass than the moon so the earth attracts the earth with a BIT larger FORCE

Albert EINSTEIN was a great SCIENTIST.

I am not STUDYING this subject now I can't say I am sorry but you are senior

answer is 4N

Explanation:

by joining the POINTS X and y we get hypotaneous of TRIANGLE

therefore

(hyp)^2=fx^2+fy^2

f^2=fx^2+fy^2

25 = 9 - fy^2

fy^2 = 25-9

therefore fy =

ong>Answer:

hey not SURE with the first one.

2. they attract each other with equal FORCES. It is not small or BIGGER the attraction is because ACCELERATION due to gravity does not depend on mass, size, shape etc of the body.

I hope it helps.

BASICALLY there are two types of OTEC system: Closed cycle and Open cycle. There is also the Hybrid cycle, which is a combination of both open and closed cycle but which is not tested yet. OTEC system uses the CARNOT cycle to generate electricity at a very low efficiency.

When the speed of an OBJECT is CONSTANTLY CHANGING, the INSTANTANEOUS speed is the speed of an object at a particular moment (instant) in time.

ong>Explanation:

ong>ANSWER:

That is because LIGHT refracts when it ENCOUNTERS different MEDIUMS. ... The EQUATION is n=c/v. Inwater, the refractive index is 1.3 and in glass, it is 1.5. Therefore, light travels faster through water,than it travels through glass.

different fluids have different reaction to heat and so when water is HEATED it absorbs heat TILL it REACHES its boiling point and turns into a vapour

in the case of petrol it has a high boiling point and HENCE it absorbs more heat heat till it reaches its vapour state and at the particular boiling point of petrol there if formation of petrol fumes

ong>ANSWER:

Oscillation is the definite displacement of a BODY in terms of DISTANCE or TIME where as vibration is the movement brought about in a body due to oscillation. Pendulum of a CLOCK is an example for oscillation. String of a guitar is an example for vibration.

Explanation:

pls mark me a brainlist

etween speed and centripetal acceleration is 90 degrees

ANGLE between speed and tengential acceleration is 0 degrees…

Angle between net acceleration and speed will be variable…

Angle at an instant will be calculated by
Let “x” be angle between speed and net acceleration, therefore
At cos x = Ac SIN x
At/Ac = TAN x
X = tan INVERSE At/Ac

Speed is the DISTANCE COVERED in unit TIME whereas velocity is the displacement covered in unit time. Speed is a SCALAR quantity and velocity is a vector. ... Speed can never be zero but the velocity can be positive, negative or zero. This is the DIFFERENCE between speed and velocity.
