The force due to gravity is equal to the product of the mass and acceleration due to gravity. Since the acceleration due to gravity is constant, we just have to rely on the comparison of their masses to determine the mass effect. Thus, the answer to this item is Wrestler C weighing 171 pounds.
Answer:
a) 8.85 kJ
b) 7.85 kJ
c) 6.85 kJ
Explanation:
we will use the energy conservation theorem for all of the stages
for stage 1:
the initial velocity and the potential gravitational energy at the bottom is zero:
for stage 2:
the velocity is constant so there is no change in the kinetic energy, so there is change only on the potential gravitational energy:
for stage 3:
there is a change for both, gravitational and kinetic energy so:
Answer:
The two cars are 1799.86m apart. Explanation: Let's use Newton's Law of Gravitation, which states that the gravitational force between two ...
Explanation:
Answer: The half-life is the amount of time it takes for a given isotope to lose half of its radioactivity. If a radioisotope has a half-life of 14 days, half of its atoms will have decayed within 14 days. In 14 more days, half of that remaining half will decay, and so on.
A. but it depends on the acid
