Answer:
In summary kinetic energy is not necessary
Explanation:
In this problem we are asked to indicate what type of energy does not need to be considered.
As they indicate that the masses do not move, scientific energy is defined by
K = ½ m v²
Since the velocities of the mass are zero, this energy is zero, so it is not necessary to take them into account in our analyzes.
In summary kinetic energy is not necessary
Answer: 4
Explanation: the scientific theory i believe can do all of the answer that are listed above
Density = 7.36 grams ÷ (2 cm × 2 cm × 2cm) = 0.92 g/cm^3
In physics, the kinetic energy<span> of an </span>object<span> is the </span>energy<span> that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this </span>energy<span> during its acceleration, the body maintains this </span>kinetic energy<span> unless its speed changes.</span>
K = ∆F / ∆s = 4N / 0.08m = 50N/m
