When a body attains terminal velocity its drag force and gravitational force on body cancels each other then why does the body still comes down instead of floating?

When the gravitational and drag forces on the object are equal, there is no net force acting on the object. This means that the body will not accelerate; it will not change it's velocity.
In order for the body to slow down to "floating speed", the drag force would have to be greater than the gravitational force. Drag force is dependent on velocity though, so the greater the velocity the greater the drag. Since the body is not accelerating at terminal velocity, it won't increase it's velocity, and therefore the drag force on it will not increase.
(This is all assuming that is a rigid body in an atmosphere with a more or less uniform density, such as a block falling from an airplane.)

An object projected up with initial velocity v attains a height h Another object projected up with initial velocity 2v will attain what height?
4h
What is displacement if a ball is thrown up with certain velocity it attains maximum height and comes back to the thrower?
Zero
What may happen to a rocket which rises from the earth never attains escape velocity?
A rocket that doesn't reach "escape velocity" will be overcome by gravity and will be pulled back down to Earth. Also, rockets which go into orbit have not reached escape velocity. Escape velocity is what is needed to completely leave earth's gravity well.
What is the average acceleration of car if it travels in a straight line in one minute and it attains a velocity of 40 meters second second and it finally?
There is not enough information to answer the question. The initial velocity of the car is not given. Also, the "it finally" at the end of the question does not make sense.
A car starts at rest and attains a velocity of 15 meters per second in 5 seconds what is its acceleration?
The average acceleration is given by the expression a ∆v/∆t (15 m/s)/5s 3m/s2 where a is acceleration, v is velocity, and t is time. ∆ (final-initial) value.
In forming the molecule HF the F atom attains the electron configuration of?
Fluorine attains the electron configuration of neon (the nearest noble gas).
Is it possible for an electron to exceed the speed of light as it is revolving around the nucleus of an atom as well as travelling through space?
No the theory of relativity clearly states that it is impossible for any body with mass to attain light velocity m = m0/(1 - v/c)1/2 from this it is clear that if a body attains light velocity its mass will be infinity which is impossible.

What happen to a rocket which rises from the earth but never attains escape velocity?
"Escape velocity" is a myth, a poorly understood fiction. "Escape velocity" is the initial velocity needed for a projectile WHEN FIRED if you want the projectile to leave the Earth entirely. Rockets, which can accelerate for a long period, never need to come anywhere close to the Earth's escape velocity of 7 miles per second in order to leave the Earth behind. However, in order to attain a stable orbit, satellites do need to accelerate to fairly high velocities; about 18,000 miles per hour in low orbit, somewhat more slowly in higher orbits.

A baseball that has a mass of 0.14 kg is thrown so that it attains a velocity of 18 m per s?
From that information we could determine its kinetic energy from the formula K.E. = ½mv² ½ x 0.14 kg x (18 m/s)² = 22.687 kg·m²/s² = 22.687 Joules
A 873 kg dragster starting from rest attains a speed of 26.3 ms in 0.59 seconds what is the average acceleration of the dragster?
The average acceleration can be calculated using the equation of motion: average acceleration = (final velocity - initial velocity) / time. Plugging in the values, we get: average acceleration = (26.3 m/s - 0 m/s) / 0.59 s ≈ 44.6 m/s^2.
