The velocity of the watermelon as it hits the ground is 14.715 m/s.
Given the data in the question;
Since the Watermelon was dropped from rest,
- Initial velocity of the Watermelon;
- Time taken for the Watermelon to hit the ground;
- We know that, Acceleration due to gravity;
Now, we determine the velocity of the watermelon as it hits the ground which is the final velocity.
From the First Equation of Motion:
Now, under gravity, acceleration ''a" will Acceleration due to gravity;
, "v" is the final velocity, "u" is the initial velocity and "t" is the time taken.
So, we substitute our values into the equation
Therefore, the velocity of the watermelon as it hits the ground is 14.715 m/s

Explanation:
Answer:
sine the resistors are connected in series, we could add the sum and that single value replaces the individual resistors in series. therefore, 100ohm resistor can do.
Answer;
the colors of light that plants require for photosynthesis
Explanation;
The color of light used for photosynthesis depends on the pigment in the plant. For example, green plants with chlorophylls and carotenoids have a maximum activity with violet-blue and red light.
White light contains various colors, including red, orange, yellow, green, blue, indigo and violet. When plants harvest light for photosynthesis, they only absorb a few colors and reflect the rest. Plants appear green because chlorophyll absorbs other colors and reflects green.
