At the bottom of the circle, the ball is being pulled upward by tension in the rope and downward by its own weight, so that the net force on it is
∑ F = 450 N - (0.75 kg) g = (0.75 kg) a
where a is centripetal acceleration. At this maximum tension, the ball has a maximum centripetal acceleration of
a = (450 N - (0.75 kg) g) / (0.75 kg) = 590.2 m/s²
Then its maximum tangential speed v is such that
a = v² / (1.0 m)
⇒ v = √((1.0 m) a) ≈ 25 m/s
Of course they can because…
Answer:
9/22 or 40.9%
Explanation:
Probability describes the likelihood of an event. To find simple probability, like in this question, use division.
To find the probability of the first question being a free response, you first need to find the total number of questions. This can be done by adding together all of the given information. There are 10 multiple choice, 3 essays, and 9 free responses.
This means that there are 22 total questions. Next, find how many of these questions are free-response. We know that there are 9 free responses and 22 questions in total. So, 9 out of 22 are free responses. This can be rewritten as 9/22.
If you want to find the percentage, simplify the fraction and convert it to a percentage.
Then, move the decimal 2 places to the right. This gives you 40.9%, which is the probability of the first question being a free-response.
The mean of a dataset is the average of the dataset.
The mean of the sample in the third row is 2.2
The dataset is given as:
5 5 3 0 6 2 2 4 5 2 3 4 3 0 1 4 0 4 3 6
From the complete question, the samples in the third row are:
Sample: 3 4 3 0 1
The mean of a dataset is calculated using:

Where:
n = 5 i.e. the number of samples
So, we have:

Add the expressions in the numerator

Divide 11 by 5

Hence, the mean of the sample in the third row is 2.2

In the excel spreadsheet, the way for one to be able to calculate the highest sales based on the criteria entered in range G2:K3 is by:
- First select cell N3 and then click on the formula tab. Then also select insert function and then click on Database, select DAVERAGE. Use A2:E52 as range, then do type "highest sales" and G2:K3.
<h3>What does Highest Sales implies?</h3>
Highest Sales is a term that connote the highest from of Qualifying Revenue that is gotten in course of a given period of time (1 year).
In the excel spreadsheet, there are different kinds of shortcut that are often used to make the calculations of works to be very easy.
Thus, In the excel spreadsheet, the way for one to be able to calculate the highest sales based on the criteria entered in range G2:K3 is by:
