Answer:
yes
Explanation:
using law of HC(heat capacity), which is
- heat loss=heat gain
- energy H=MCQ
Where M is mass of substance,C is specific heat capacity, and Q is temperature change
In case of two substance
- the H = Mc*Cc*Q+Mw*Cw*Q(provided the initial and final temperature are given)
Answer:
F in the definition of potential energy is the force exerted by the force field, e.g., gravity, spring force, etc. The potential energy U is equal to the work you must do against that force to move an object from the U=0 reference point to the position r.
Explanation:
D. lost an electron
because they have free electron in the outermost shell which they will like to denote, in order to attain stable configuration
Answer:
B
Explanation:
Heat energy of a substace can be calculated using
Q = mcθ
where Q = Heat energy
m =mass
c = specific heat capacity
θ =temperature difference
Temperature difference is final temperature - initial temperature.
So we get,
Q = 1 × 600×(100-20)
= 48000 J
Answer:
I think its a fuse because everything else makes sense and is used in electrical circuits and the fuse is the only one that stands out to me ¯\_(ツ)_/¯
