Answer:
The new angular velocity will be "80.73 rad/sec".
Explanation:
The given values are:
Angular velocity, W = 20 rad/s
M = 30 N
Time, t = 5 seconds
As we know,
On putting the values in the above formula, we get
Answer:
20 m/s
Explanation:
First, you have to convert kilometers (72) to meters (72.000) then do the same with hours (1 hour) and seconds (3.600) Divide this numbers and you will get a result.
Answer: The half-life is the amount of time it takes for a given isotope to lose half of its radioactivity. If a radioisotope has a half-life of 14 days, half of its atoms will have decayed within 14 days. In 14 more days, half of that remaining half will decay, and so on.
Well visual and perceptual are both the way you see things and tactile is touch so it has to be Olfactory
