Answer:
334.4J
Explanation:
Q = mass×specific heat capacity (final temperature - initial temperature) = 100 × 4.18 (23.40 - 22.60) = 100 × 4.18× 0.80 = 334.4J
Answer:
Explanation:
Well use the combines gas law to evaluate this question;
P₁V₁/T₁ = P₂V₂/T₂ (Remember that at sea level the pressure is usually 1 atm)
1 * V₁ / 294.25 = 0.72 * V₂ / 277.95 (NB: Temperatures have to be in Kelvin)
V₁ / 294.25 * 277.95 = 0.72 V₂
0.945 V₁ = 0.72 V₂
0.945/0.72 V₁ = V₂
1.312 V₁ = V₂
The volume (V2) at 3000 m altitude will be <u>1.312 </u>bigger than the initial volume at sea level.
Explanation:
The answer is A (3,2,1,3)
Answer:
in my opinion
Explanation:
the length measured in wave is called wavelength.and frequency is the amount of wave travel in a wave . energy is carried by the frequency.so they are automatically related with each other.
iam just an student. ihas told what I had understand.thankyou
