Answer: On Monday, XX/XX, the XXXX you presented in our weekly review were not accurate and I’m worried that this reflected poorly on our team’s credibility. This could negatively impact senior leadership’s confidence in our team’s effectiveness at a time when headcount is already being scrutinized and potentially eliminated. Next time you present XXXX, my expectation is that everything will have been double or triple-checked in advance of the meeting so that all figures are reported accurately.
Answer:
T = 0.607 seconds
Explanation:
Given:
Mass, M = 1.50 × 10⁻² kg
Radius, R = 5.50 × 10⁻² m
Now,
the time period in terms of moment of inertia is given as:
.....................1
where, T is the time period
g is the acceleration due to gravity
I is the moment of inertia
Now,
Moment of inertia, I is given as:
on substituting the moment of inertia in the equation 1, we get
or
on substituting the valeus, we get
or
T = 0.607 seconds
Hence, the time period is 0.607 seconds
Answer:
Lithium and Sodium
Explanation:
Lithium and Sodium is in the same group 1A
Answer:
Alpha = ω^2 R where R is radius of blade
g = w^2 r where r is distance from center
ω^2 R = 11.5 ω^2 r
R / r = 11.5 / 9.8 = 1.17
Or r = .852 R
Since the angular acceleration depends on both R and ω it seems that one can only get r as it depends on R
