The ratio of distances traveled by a body in free fall starting from rest in the first and third seconds is 1:9. This is because the body's distance traveled in each second increases in proportion to the square of the time elapsed.
Wavelength is the distance from one molecule to the nearest molecule occupying a similar position and moving in the same direction.
If we know the speed and the time taken for a body to cover a distance, then we can find the distance covered by it as follows: distance=speed*time
No, distance does not affect the body's acceleration when moving in a straight line with constant acceleration. The acceleration of an object depends only on the force acting on it, not the distance it travels. The acceleration will remain constant unless a different force is applied.
If the 'weight' of a body is the gravitational force between the body and the Earth, then as long as the body stays at about the same distance from the center of the Earth, its weight is constant, and has no connection with its motion.
The ratio of distances traveled by a body in free fall starting from rest in the first and third seconds is 1:9. This is because the body's distance traveled in each second increases in proportion to the square of the time elapsed.
acceleration of a falling body is 9.8m/s*s and its direction is vertically downward.
Seconds times seconds -- for example, the acceleration of a falling body in the earth's gravitational field is equal to 9.8 metres per second squared, so if a body has been falling for 5 seconds, the equation reads 9.8M x 5 x 5
heres the average 2.2 seconds
If air resistance can be ignored, the distance in meters is 4.9t2. Note that 4.9 is half the numerical value of Earth's acceleration (9.8 meters per second square).

according to Newton"s third law,the force on a falling body is equal to the force exerted by the earth on the body which is given as the product of mass of the body and acceleration due to gravity,ie, F=mg (g=9.8 m per seconds sq.)
Time to hit bottom of a cliffIf you ignore the air resistance, any falling body will accelerate at the same constant rate under the action of gravity. On the earth, the accelaration of the gravity is about 9.81 m/s2 (9.81 meter per second squared). This is to say that the speed of the falling body will increase by 9.81 m/s, every second.For a body accelerating from rest, the distance travelled and the time elapsed are related by the equation:D = (a*t2)/2where 'D' is the distance, 'a' the acceleration and 't' the time. Furthermore, the velocity 'V' of the body after 't' seconds under the same acceleration will be:V = a*tUsing these two relations, one can easily determine that a body falling from the top of a cliff 50 meters high will hit the bottom in about 3.19 seconds, at a speed of approximately 31.3 m/s (which is about 112,8 km/h or 67.7 mph).

Wavelength is the distance from one molecule to the nearest molecule occupying a similar position and moving in the same direction.
Hormones, or chemical messenger, is introduced into the blood or lympathic system then travels to other parts of the body.
If we know the speed and the time taken for a body to cover a distance, then we can find the distance covered by it as follows: distance=speed*time
