30 × 10 × 30 = 9000J or 9KJ
Answer:
<em>Gravitational</em><em> force</em>
Explanation:
............
Answer:
121550 J
Explanation:
Parameters given:
Mass, m = 0.34kg
Specific heat capacity, c = 14300 J/kgK
Change in temperature, ΔT = 25K
Heat gained/lost by an object is given as:
Q = mcΔT
Since ΔT is positive in this case and also because we're told that heat was transferred to the hydrogen sample, the hydrogen sample gained heat. Therefore, Q:
Q = 0.34 * 14300 * 25
Q = 121550J or 121.55 kJ
Of approximately 1 to 4 kHz6 and approximately 16 kHz for mice.
