Answer:
Aluminium, Nickel, Cobalt and Iron plus varying levels of Copper, Titanium and Niobium.
MAGNETIC: Alni, Alcomax, Hycomax, Columax, and Ticonal.
Answer:
A)
Explanation:
Energy transformation is when energy changes from one form to another.
density equals mass over volume for example: d=m/v, so 45.837g/1703.3414cm =
p = 0.02691 g/cm3
=11.943cm
You would have to do some conversion to get the 11.943cm
Answer:
c.an equation that can be used to accurately calculate the pull of gravity between two objects
Explanation:
umm ok for you
Answer:
ΔU = -70 J
Explanation:
ΔU = Q − W
where ΔU is the change in internal energy,
Q is the heat absorbed by the system,
and W is the work done by the system (on the surroundings).
30 J of thermal energy is released, so Q = -30 J.
40 J of work is done by the system, so W = 40 J.
Therefore, the change in internal energy is:
ΔU = -30 J − 40 J
ΔU = -70 J
