Answer:
Nearest, the revolutions per minute will be 29.
Explanation:
Given that,
Radius of circle = 1 m
Acceleration a =g
We know that,
Angular frequency is defined as,
Where, n = number of revolutions in one second
We need to calculate the revolutions in one second
Using formula of centripetal acceleration
Put the value of a and ω
Put the value into the formula
We need to calculate the revolutions per minute
Using value for the revolutions per minute
Hence, Nearest, the revolutions per minute will be 29.
Answer:
Explanation:
A scenario in which an authoritarian leadership would be beneficial is in law enforcement in emergency cases (that has to do with public safety or national security) without the bureaucratic bottlenecks of the legislature and judiciary. For example, the recent coronavirus pandemic, authoritarian leaderships would find it easier to enforce the laws on wearing of masks and also prevent producers of personal protective equipment (PPE) from unreasonably inflating prices of there PPEs.
As explained above, it would work well because there will be no legislative bottleneck that will start a hearing at the expense of public safety neither will there be a court that will stall the process at the same expense.
The risks here is that businesses (in this case that of producing PPEs) may find it difficult to survive since the "tone" of the pricing of PPEs will now be determined by government. It may even hinder healthy business competition. It may also lead to production of substandard PPEs in order to generate enough profit (since the main aim of any business is to generate profit).
Answer: D
Experiment 1 has a confounding variable related to the mass of the rockets. Any variation in mass may cause a discrepancy in the distance traveled.
This is the answer to the question because:
- Both experiments do have a confounding variable.
- Experiment 1 doesn't have to stay constant.
- A double-blind experiment will not do anything to the placebo.
- High blood pressure people will not make the results confusing.
The answer has to be the option D. Hope this helps you!
