Hello!
In this case, since equilibrium temperature problems involve the mass, specific heat and temperature change for the substances at different temperatures, we can write:
Thus, since we are talking about water and they both have the same specific heat, we can write:
Now, we plug in the temperatures to obtain:
Next, since the total volume of water is 800 L, since it has a density of 1kg/L, we infer the total mass is 800 kg; that is why we can write a 2x2 system of simultaneous equations:
Thus, the masses of both cold and hot water turn out:
Best regards!
Answer:
The answer to the question is
A 100 lb person would weigh 300.33 lbf at the upper atmosphere of Jupiter
Explanation:
To solve the question we note that
Mass of object = 100 lb = 45.35924 kg
Mass of Jupiter = 300×Mass of Earth = 300×5.972 × 10²⁴ kg =1.7916×10²⁷ kg
Radius of Jupiter = 10× Radius of Earth = 10×6,371 km = 63710 km
Gravitational constant, G = 6.67408 × 10⁻¹¹ m³ kg-1 s-2
Gravitational force is given by
Plugging in the values we get
=
= 1335.93 N
Converting into lbf gives 1335.93 N *0.2248 lbf/N = 300.33 lbf
