Explanation:
The given data is as follows.
mass = 227.8 kg, volume = 0.1189
It is known that formula for volume of a sphere is and density is as follows.
Density = ........ (1)
=
= 1915.895
Hence, putting the given values into equation (1) as follows.
Density =
1915.895 =
= 227.8
r = 0.305
Thus, we can conclude that radius of the sphere is 0.305 .
Answer:
v₀ = 26.17 m/s
Explanation:
If
R = Xmax = 50 yards = (50 yards)*(0.9144 m / 1 yard) = 45.72 m
t = 5 s (Time of Flight)
we can apply the equation:
R = V₀x*t ⇒ V₀x = R / t = 45.72 m / 5 s ⇒ V₀x = 9.144 m/s
then we use the equation of Time of Flight:
t = 2*V₀y / g ⇒ V₀y = g*t / 2 = (9.81 m/s²)*(5 s) / 2 ⇒ V₀y = 24.525 m/s
Finally we apply
v₀ = √(V₀x² + V₀y²) ⇒ v₀ = √(9.144² + 24.525²) m/s
⇒ v₀ = 26.17 m/s

Answer: Bohr developed the Bohr model of the atom, in which he proposed that energy levels of electrons are discrete and that the electrons revolve in stable orbits around the atomic nucleus but can jump from one energy level (or orbit) to another. ... During the 1930s Bohr helped refugees from Nazism.
