Dalton's <span>law of partial pressures
</span>
Answer:
70 W
Explanation:
Power = work / time
P = mgh / t
P = (80 kg) (9.8 m/s²) (3000 m) / (36000 s)
P = 65.3 W
Rounding to one significant figure, the average power output is 70 W.
Answer:
Applications of Avogadro's hypothesis:
In explaining Gay Lussac's law of gaseous volumes.
In determining the atomicity of gasses.
In determining the molecular formula of a gas.
In establishing the relationship between relative molecular mass and vapor density.
Explanation:
Answer:
Total kinetic energy of entire system is 3 mgl
Explanation:
Given two masses: m and 4m.
Since the pulley is frictionless and the thread is massless, the energy here is linked to the two masses.
Total kinetic energy of entire system = decrease in gravitational potential energy of the system.
Therefore, we have :
ΔKE = Δp
ΔKE = 4mgl - mgl
= 3 mgl
Total kinetic energy of entire system is 3 mgl
Answer:
Normal force
Explanation:
Normal force is the force that surfaces employ so that solid objects are disallowed from passing through each other.
