Answer:
0.4762 J/g°C.
Explanation:
<em>The amount of heat released to water = Q = m.c.ΔT.</em>
where, m is the mass of water (m = 15.0 g).
c is the specific heat capacity of water = ??? J/g°C.
ΔT is the temperature difference = (final T - initial T = 37.0°C - 30.0°C = 7.0°C).
<em>∴ The specific heat capacity of water = c = Q/m.ΔT</em> = (50.0 J)/(15.0 g)(7.0°C) = <em>0.4762 J/g°C.</em>
It’s ether B or D I think it’s B tho

C because ships and other boats has underwater microphones underwater because on most cargo ships the engine is to loud so they use microphones underwater to detect torpedos so your answer is C
Answer:
the equilibrium bond length of H137I is
Explanation:
The quantum state has a rotational energy which can be expressed mathematically
Here,
B is the rotational constant given as
We are given from the question that
Substituting we have
Where,
h is plank constant
r is radius
I is moment of inertia
Making the subject
The moment of inertia = Reduced mass ×
Therefore
Making the subject of the formula
