Answer:
B. dark matter
Explanation:
The<u> current theory</u> is that the dark matter composes about 85% of the matter in the whole universe, possibly in large majority made out of unknown material. What we found so far is that the majority of the dark matter is NOT composed of baryonic material (the stuff that makes stars and planet).
We know dark matter exists and we suppose there's a HUGE amount of it that fills the gaps between stars and planets.
Answer:
Explanation:
Given that,
The radius of a flywheel, r = 0.3 m
Angular acceleration of a flywheel, 
We need to find the magnitude of the tangential acceleration after 2.00 s of acceleration.
The relation between the tangential and angular acceleration is given by :
So, the required magnitude of tangential acceleration is .
Absorption occurs when <span>all of the energy from light waves is transferred to a medium! </span>
v₀ = initial speed as tarzan grabs the vine = 5.3 m/s
v = final speed as the tarzan reach the maximum height = 0 m/s
h = maximum height gained by the tarzan
m = mass of tarzan
using conservation of energy
initial kinetic energy = final kinetic energy + potential energy
(0.5) m v²₀ = (0.5) m v² + m g h
(0.5) v²₀ = (0.5) v² + g h
(0.5) (5.3)² = (0.5) (0)² + (9.8) h
h = 1.43 m
