Answer:

20m

Explanation:

Using the equation s=d/t and re arranging it to solve for distance, d=St, where d=distance, s=speed, ant t=time, we can plug in known variables.

d=4*5

d=20m

there is a distance of 20m traveled

Which measure of central tendency refers to the average of all the scores in a data set?
dedylja [7]

<u>Answer</u>

Mean


<u>Explanation</u>

For any set of date there is a typical value for the probability distribution called central tendency.

There three types of central tendency<em> mean, median and mode.</em>

Mean is the average value of all data set in a distribution.

median is the the central value when the data is arranged in ascending or descending order.

Mode is the value that occurs most in a set of data.

An electric fan is running on HIGH. After fan has been running for 1.1 minutes, the LOW button is pushed. The fan slows down to
madam [21]

Answer:

ωi = 15.4 rev/sec

Explanation:

Since the movement of the fan is rotating, we are thus dealing with Rotational motion. In rotational motion, for angular speed to take place also means angular acceleration is also occurring.

angular acceleration = α = (change in speed)/(change in time)

angular acceleration = α = Δw/Δt = (ω - ωi) /(t- t₀) ..........(equation 1)

                                      α =  (ω -ωi) /(t- 0)

                                      α =  (ω-ωi) /t

                                      ωi  =  ω - αt ......................................(equation 2)

where ωi is the initial angular speed.

We replace the values for ω, t and α

ωi = 105 rad/sec - ( 4.4 rad/sec² )(1.85s) = 96.86 rad/s = 15.415747788 rev/sec

Solve for A if F=MA and F=100 and M=25?
inn [45]

Answer:

<h3>\boxed{ \boxed{ \bold{A = 4}}}</h3>

Explanation:

Given,

F = 100 , M = 25

Now, let's find the value of A

\sf{F = MA}

plug the values

⇒\sf{100 = 25 A}

Swap the sides of the equation

⇒\sf{25A = 100}

Divide both sides of the equation by 25

⇒\sf{ \frac{25A}{25}  =  \frac{100}{25} }

Calculate

⇒\sf{A = 4}

Hope I helped!

Best regards!!
