It means mass can be converted into energy.

I. E. In a nuclear fission, we start of with a greater mass of our rectant, which then decrease due to mass being converted into the (thermal) energy released, in our reaction. Later, being used to produce electricity, for example.

Hope this helps!

Mya (m = 65 kg) floats 4 m from her spaceship (m = 1600 kg). What gravitational force would each mass exert on the other?
Aleksandr-060686 [28]

Answer:

ans: 4.34 × 10^(-9) N

Explanation:

mass of Mya say (m) = 65 kg

mass of spaceship say (M) = 1600 kg

universal gravitational constant(G) =6.67 × 10^(-11) Nm²/kg²

separation distance (d) = 4m

so,

gravitational force (F)= GMm/d²

=( 6.67 × 65 × 1600) / ( 10¹¹ × 4²)

= 4.34 × 10⁴ / 10¹³

= 4.34 × 10^(-9) N

4. What information does the atomic number of an element give us?
bulgar [2K]

Answer: It gives us the identity of the element as well as the number of protons.

Explanation:

Because the number of protons is specific for each element, we can determine what element we are looking at just by the atomic number. For example the element with the atomic number of 1 is Hydrogen, atomic number of 2 is Helium, atomic number of 3 is Lithium and so forth.
