Melting ice would damage this polar bears habitat meaning the polar bear may decrease
Explanation:
...domains are aligned which creates a magnetic field.
... are not always aligned so the resulting element had no apparent magentism
1.radio waves
2.microwaves
3.infrered
Answer:
Explanation:
Distance to Andromeda galaxy
Speed of light is
Time is given by
Hence, the light from Andromeda left ago
Energy or heat can be calculated in terms of the mass, temperature, and specific heat of a substance. This is given by the equation:
U = mCpΔT = mCp(Tf-Ti)
where:
m = mass
Cp = specific heat
ΔT = temperature difference
For this problem, you need to get the specific heat of granite which can be found in reliable chemistry/engineering books or websites. According to Engineering Toolbox website, the Cp of granite is 790 J/(kg-°C).
U = 17 kg (790 J/(kg-°C)) (21-45) = - 322,320 Joules
*Note: the sign is negative because energy was released
