In the presence of air resistance, a watermelon is launched into the air with 100 j of kinetic energy.
Its kinetic energy is less than 100 J when it reaches its starting point. Its kinetic energy decreases as it encounters air resistance and returns to its starting point. In actuality, some of the energy has been lost because of air resistance. Since we use the ball's original height as a point of reference, there is no potential energy when the ball is in its initial state of motion, and K is its kinetic energy. This total energy is conserved if there is no air resistance, therefore when the ball returns to its starting position, its kinetic energy will remain at 100.

Answer:
7.8 mm
Explanation:
Wavelength = λ = 710 nm = 710×10⁻⁹ m
Distance between light sources = L = 9 m
Diameter of pinhole = d = 1 mm = 1×10⁻³ m
Rayleigh Criterion
Distance between difraction pattern is 7.8 mm.
Answer: Inertia
Explanation: Objects to stay in motion or at rest unless there is an external unbalanced force aced upon the object.
The answer to this question is two violins, a viola and a cello
The string quartet is one of the earliest form of musical ensembles in history. This form of ensembles was brought to recognition by the Austrian composer Joseph Haydn<span>, with his works in the 1750s establishing the genre and this form is still considered one of the hardest ensembles because each player has to cover a lot of parts within a session.</span>
One of the most important reasons is that when mountains were built there were events such as tilting. Because of that most of the sedimentary rocks were no longer horizontal.We know that because of the law of original horizontality
