1 revolution (1 circle) is equivelant to 360 degrees, or 2 pi radians. In this way, 1 revolution per second is equal to 2 pi radians per second. Therefore, to get 300 revs per sec in rads per sec, simply multiply 300 by 2 pi radians: 300*2pi = 300*2*3.1415 = 1885 revs per sec
The acceleration of the particle moving in a circular path is given by the formula a = rω^2, where r is the radius of the circle and ω is the angular speed. Plugging in the values, a = (1.5 m)(rads/s)^2 = 2.25 m/s^2.
Wf - Wi = a*t, where Wi and Wf are the initial and final angular velocities, respectively, a is the angular acceleration, and t is time. So, a*t = 15.4 rad/s - 8.5 rad/s = 6.9 rad/s, thus a = 6.9 rad/s / 5.2 s = 1.3 rad/s2.
To find the instantaneous angular acceleration, you need to know the time rate of change of the instantaneous angular velocity. Without this information, you cannot calculate the instantaneous angular acceleration at t=5.0s.
Rads and grays are units used to measure radiation exposure. Rads are an older unit that measures the amount of energy absorbed from ionizing radiation by matter. Grays are the newer, more internationally accepted unit that measures the absorbed dose of radiation.
The minimum angular velocity required to prevent spilling water is given by the equation ω = sqrt(g/L), where g is the acceleration due to gravity (approximately 9.81 m/s^2) and L is the length of the arms in meters (63 cm = 0.63 m). The distance from the handle to the center where the bucket is hanging does not affect this calculation. Thus, the minimum angular velocity can be calculated as ω = sqrt(9.81/0.63) ≈ 4.37 rad/s.

rads/s radians/second Usually its stated as rpm (rounds per minute) but it usually needs to be converted to rads/s for calculations. 1 rad/s= (1 rpm)*2*pi/60
One gray=0.01 Rads...Incorrect (very), Correct.....One Gray = 100 Rads.
200 to 1000 rads will cause illness with a greater effect towards the end. Any dose over 1000 rads will often prove to be fatal.
BI-RADS is simply the word used in the categories of mammogram results. BI-RADS 0 means additional imaging is needed. BI-RADS 1 means no evidence of cancer. BI-RADS 5 means likely cancer. There are a range of results in between.

BI-RADS is a system of categorizing results of mammograms. BI-RADS 2 means that the finding is benign -- not cancer. Such a result would be typical if a lymph node were found in the breast.
BI-RADS 4 on a mammogram means there is a suspicious abnormality, and a biopsy might be required. It does not necessarily mean cancer.
BI-RADS is a scale or system for categorizing mammogram results. Like the Richter scale measures earthquakes, and the Fahrenheit scale measures temperature, BI-RADS is a way of classifying mammogram results so that communication between health care providers is easier.
