Answer:
The circular solar orbital speed at 4.0AU is 1/4( one fourth) that at 1.0AU
Explanation:
am = mvr= angular momentum
am4= 4mvt
am1= mvp1
Vt=1/4vp
Vp=4vt
am1= 4mvt
am1=am4
The circular solar orbital speed at 4.0AU is 1/4 (one fourth) that at 1.0AU
Helium has only 2 electrons in it's valence shell
So, option D is your answer.
Hope this helps!
Answer: Acceleration does not increase over time once a force is applied to the object. It depends on the force and the object's mass. If those don't change, then the acceleration is constant.
Explanation:. F = M • a
We don't know either of those numbers, so we can't answer the question.
Speed = (distance covered) / (time to cover the distance).
= (1.92 meters) / (4.47 x 10⁻⁸ second)
= 42,950,000 meters/second (rounded to the nearest 10,000 m/s)
That's about 96.1 million miles per hour, or about 14% of the speed of light.
To answer this question do you need to know the formula to get the rate of change of acceleration (a=Δv/Δt; Δv= final velocity - initial velocity) and the formula to find the force of an object given a constant acceleration (F=m*a). Given these two formulas you can applicate them to solve for the mass of an object.
