Answer:
Oxygen and methane can react chemically with each other, so we would not see them together unless there are active sources for both. On Earth, biology is responsible for essentially all the oxygen and the majority of the methane in our atmosphere.
Torque = Force * Distance
Force = Weight = m1*g = 93*9.81 = 912.33 N
Distance from the pivot to person 1, d1 = 0.8 m
Therefore,
Torque = 912.33*0.8 = 729.864 N.m
Answer and explanation:
The nuclei don't have a permanent electric dipole because they have a positive homogeneous distributed net charge. The requirement for the existence of a permanent electric dipole is that the body has positive and negative charges distributed in an inhomogeneous way, where positive and negative charges are well-differentiated and incapable of mooving its relative position. This is exactly what happens with molecules.
Magnetic dipole moments are related to sub particle movement inside atomic particles. That's why nuclei and molecules have it.
Answer:
net outward force on a passenger's eardrum is 0.6115 N
Explanation:
Change in pressure is calculated as follows
h= height of liquid column =480 m
ρ= density of liquid= 1.3 kg/m^3
putting values we get
ΔP= 6115 Pa
Area of the eardrum is approximately
= 1 cm^2
Therefore, net force F = AΔP
= 
= 0.6115 N
