A solid, liquid, or gas or plasma. Which I think it is. Check though.
Answer:
Explanation:
The angular momentum of electron mvR = 6 x 10⁻²⁵ Js
Magnetic field B = 2.5 x 10⁻³ T
radius of circular path R = mv / Bq
where m is mass , v is velocity and q is charge on electron
R² = mvR / Bq
R² = 6 x 10⁻²⁵ / 2.5 x 10⁻³ x 1.6 x 10⁻¹⁹
= 1.5 x 10⁻³
R = 3.87 x 10⁻² m
mvR = 6 x 10⁻²⁵
v = 6 x 10⁻²⁵ / mR
= 6 x 10⁻²⁵ / 9.1 x 10⁻³¹ x 3.87 x 10⁻²
= .17 x 10⁸
= 17 x 10⁶ m/s
Answer:
Kinematics is the motion of objects without reference of forces that causes the motion in objects.
Explanation:
B) Planck. He is not a developer of an atomic model.
Answer:
814.62 million kilometers
Explanation:
eccentricity of elliptical orbit =0.048
Let semi major axis of elliptical path be a.
From center of the ellipse focus is at a distance = a*eccentricity
Now, closest approach from focus is = a(1-e)
After plugging values = a(1-0.048)=740.52
a=777.31 million kilometers
Maximum distance from sun (apihalian) =a+a*e =a(1+e)
= 777.31(1+0.048)
=814.62 million kilometers
