The height of the water tower is found to be 54.66 meters.
<h3>What is acceleration due to gravity?</h3>
A free-falling object is one that is falling solely due to gravity.
Some key features regarding the acceleration due to gravity are-
- A free-falling component has a downward acceleration of 9.8 m/s/s (on Earth).
- This magnitude for the acceleration of a free-falling object is so significant that it has its own name.
- The acceleration of gravity is the acceleration of any object moving solely under the influence of gravity.
- In fact, the acceleration of gravity is so important quantity that scientists have a special symbol to represent it - the symbol g.
- The most precise numerical value for gravity's acceleration is 9.8 m/s/s.
Now, according to the question;
It takes a watermelon 3.34 sec to reach the ground.
Use the equation of motion in straight line.
D = (1/2) x (gravity) x (time)²
D is the height of the water tower.
= (1/2) x (9.8 m/s²) x (3.34 sec)²
= (4.9 m/s²) x (11.16 sec²)
D = 54.66 meters.
Thus, the height of the water tower is estimated as 54.66 meters.

Answer:
The gradient of a line is given by .
Any 2 points of a vertical line would have the same x-coordinate. Thus when you simplify the denominator, you would end up with a zero. If you enter that into your calculator, no matter what you numerator is, you would get a Math error. This is because you cannot possibly divide a number by zero. Thus, the gradient is undefined.
13 tricycles are the total number of tricycles shipped out.
13 tricycles+3bicycles=16
13×3=39 3×2=6
39+6=45
Answer:
27.7% larger
Step-by-step explanation:
6 x 113% = 6.78
9 x 113% = 10.17
Old Area = 9 x 6 = 54 sq in
New Area = 6.78 x 10.17 = 68.95
(New - Old) ÷ Old = .277 = 27.7%
