Answer:

Explanation:

Nuclear fission is the process of splitting apart nuclei. When nuclei fission energy is released. So much energy is released that there is a measurable decrease in mass, from the mass-energy equivalence. This means that some of the mass is converted to energy.

Answer:

Explanation:

Fission is the break of the nuclei of an unstable atom, releasing heat in the process. By the graph shown, U-238 has less average binding energy per nucleon comparing to U-235. Because it has less binding energy, it is more difficult for it to react (it has less energy to release), so it is more stable than U-235.

The product of its fission is the U-235, an isotope that has a small mass than the uranium. So the mass that is lost during fission is converted to the binding energy in the isotope, making it slightly higher (the difference of mass is only 3 amu).

What is the acceleration due to gravity at an altitude of 116?

Schach [20]

Gravitational acceleration (Ga) is inversely proportional to k / Distance^2

so Ga * Distance^2 = K

On the surface of Earth acceleration due to gravity is about 9.8m/s^2 with an average distance to the earths core of about 6371 km (Wolfram alpha).

So k = 9.8 * 6371^2
I'm presuming that your distance of 116 is km

As
Ga = k / distance^2

Ga = ((9.8 * 6371^2) / (6371 + 116)^2 ) = 397778481.8 / 42081169

= 9.45 m/s^2 to 2sf

Please somebody help i took screenshot ik there is a blank space but look down a little

Answer:

Force has a direct relationship to mass and acceleration. Newton's Second Law, force equals mass times acceleration (F=MA), illustrates their general relationship in an equation.

Explanation:

Relationships to remember:

Force and acceleration have a direct relationship, meaning if force increases, acceleration will also increase and vice versa

(Ex: The harder you push a box, the faster it will move)

Mass and acceleration have an inverse relationship, meaning if mass increases, acceleration will decrease and vice versa

(Ex: If you add more furniture in the back of a moving company truck, the truck will move slower than it did before the furniture was added)

Force and mass have a direct relationship, meaning if mass increases, force will also increase

(Ex: You will need to exert less force to lift a 5-pound weight than a 10-pound weight)

And of course, Newton's Second Law, F=MA sums all of this up in 3 letters and a symbol! If you have any more questions about this problem, please comment on my answer :)
