Answer:
Explanation:
Since the centripetal force F_C is, in this case, the gravitational force F_G exerted by the planet, we can say that:
In the case of the satellite A we have:
And in the case of the satellite B:
Finally, using these two expressions, we obtain :
In words, the centripetal acceleration a_b is equal to one fourth of a_0.
An atom is the smallest unit of an element
Moment of inertia of N₂ molecule about an axis passing through the center of mass perpendicular to the line joining the two atoms=i=2.51 x 10⁻⁴⁷ kg m²
Explanation:
Moment of inertia= i= mr₁²+ mr₂²
m= mass of nitrogen atom=2.32 x 10⁻¹¹pg=2.32 x 10⁻²⁶ Kg
r1= r2=0.0465/2= 0.02325 nm=2.325 x 10⁻¹¹ m
so i= 2.32 x 10⁻²⁶ (2.325 x 10⁻¹¹)²+2.32 x 10⁻²⁶ (2.325 x 10⁻¹¹)²
i=2.51 x 10⁻⁴⁷ kg m²
<u>Answer:</u>
"They stay in place and vibrate" is true about the particles of iron.
<u>Explanation:</u>
The iron in solid state have tiny particles like atoms, molecules and ions which stay in their position and can only vibrate slightly as their arrangement is compact in nature which do not allow them to move all over the place due to strong force of attraction called as "inter-molecular attraction".
While iron in molten form, being semi-solid have more spaces between the particles, therefore they vibrate more than the particles in compact situation of solid state. And definitely the inter-molecular force of attraction is also weaker than in between actual solid iron particles.
Answer:
New pressure group is N
Explanation:
The Repetitive Dive table has to be checked, the residual nitrogen for the maximum depth of 38 feet as a "D" diver, then add that to the actual dive time to get the total nitrogen time. The total nitrogen time and the maximum depth of 38 feet would put you on a pressure group N.
