Answer:
The straight line that is obtained, intercept it on the y-axis and the value of displacement will obtained.
Explanation:
Answer:
T= 37 day
Explanation:
To solve this exercise we will use the definition of angular velocity as the angular distance, which for a full period is 2pi between time.
w = T / t
The relationship between angular and linear velocity is
v = w r
w = v / r
We substitute everything in the first equation
v / r = 2π / t
t = 2π r / v
Let's reduce to the SI system
V = 2 km / s (1000m / 1km) = 2 10³ m / s
r= R = 6.96 10⁸ m
Let's calculate
t = 2π 6.96 10⁸/2 10³
t = 3.2 10⁶ s
T = t = 3.2 10⁶ s ( 1h/3600s) (1 day/24 h)
T= 37 day
C. A flow of matter from one point to another.
Nuclear decay is spontaneous.
Nuclear fission does occur spontaneously but at a
very low level in fissionable materials. The main difference between fission
and nuclear decay is that fission can occur by neutron bombardment. And when
the neutron source is also other fissioning atoms, a chain reaction can may
happen. <span>
No chain reaction is possible with nuclear decay.
<span>That would be a much better characteristic to look at.</span></span>
