Nope......... Constant speed but change in direction can cause acceleration which would give a finite force........

Answer:

f' = 2 f

Explanation:

The frequency of the pendulum that swings in simple harmonic motion is given by :

f={2\pi}\sqrt{\dfrac{l}{g}}

Where

l is the length of pendulum

g is the acceleration due to gravity

If the length of the thread is increased by a factor of 4, such that, l' = 4 l, let f' is the new frequency such that,

f'={2\pi}\sqrt{\dfrac{l' }{g}}

f'={2\pi}\sqrt{\dfrac{4l}{g}}

f'=2\times {2\pi}\sqrt{\dfrac{l}{g}}

f' = 2 f

So, the new frequency of the pendulum will become 2 time of initial frequency. Hence, the correct option is (b) "2f"

When does a scientist create the conclusion?
Gre4nikov [31]


The best answer is d - while comparing the data with the hypothesis. The scientific method defines the correct steps as:

1. observation - use of the five senses to learn about something.

2. Question - where you raise questions based on your observation.

3. Hypothesis - a prediction or guess of what the answer to the question is.

4. Method - point where you test the hypothesis by carrying out an experiment.

5. Results / data - this is what happened after each step of the experiment.

6. Conclusion - where the results of the experiment are discussed and it  is summarized if the prediction was true or not, based on data from the results.
