Answer: 12 values

Explanation:

In statistics, a Boxplot is a graph that is a good indicator of how the values in the data are spread out. It is useful when we need to compare distributions between many groups or datasets. It is composed of Outliers, which display low minimums and high maximums. Also, it shows The Interquartile Range by a square composed of Q1 (quartile 1), Q2 (quartile 2) and Median.

Quartiles are values that divide data into quarters, where Q1 represents the lowest 25% of numbers, Q2 represents the next lowest 25% of numbers, Q3 represents the second-highest 25% of numbers above the median and finally, Q4 represents the highest 25% of numbers.

In this case,  her data set is composed of 48 values obtained by the survey Makenna did in her class. Then, numbers above the third quartile for her box plot will be Q4 values, hence, the highest 25% of numbers are:

                                              48 x 25% = 12

a charged partocle produces an electric field with a magnitude of 2.0 N/C at a point that is 50cm away from the particle
zheka24 [161]

The charge on the particle is 5.6 × 10⁻¹¹ C.

<h3>Calculation:</h3>

The magnitude of an electric field produced by a charge is given by:

                                                 E = q/ 4πε₀r²

where,

E = electric field

q = charge

r = distance

1/4πε₀ = 8.99 × 10⁹ Nm²/C²

Given,

E = 2.0 N/C

r = 50 cm = 0.5 m

To find,

q =?

Put the values in the above equation:

E = q/ 4πε₀r²

q = E (4πε₀r²)

q = 2.0 × (0.50²)/ 8.99 × 10⁹

q = 5.6 × 10⁻¹¹ C

Therefore, the particle has a charge of 5.6 × 10⁻¹¹ C.

<h3>What is an electric field?</h3>

The physical field that surrounds each electric charge and acts to either attract or repel all other charges in the field is known as an electric field. Electric charges or magnetic fields with different amplitudes are the sources of electric fields.

I understand the question you are looking for is this:

A charged particle produces an electric field with a magnitude of 2.0 N/C at a point that is 50 cm away from the particle. What is the magnitude of the particle's charge?

A hockey puck is struck so that it slides at a constant speed and strikes the far side of the rink, 58.2 m away. The shooter hea
DENIUS [597]

Answer:

v = 33.66 m/s

Explanation:

Let hockey puck is moving at constant speed v

so here we have

d = vt

so time taken by the puck to strike the wall is given as

t = \frac{58.2}{v}

now time taken by sound to come back at the position of shooter is given as

t_2 = \frac{58.2}{340}

t_2 = 0.17s

so we know that total time is 1.9 s

1.9 = t + t_2

1.9 = t + 0.17

1.9 - 0.17 = t

t = 1.73 s

now we have

1.73 = \frac{58.2}{v}

v = 33.66 m/s

on a recent adventure trip, Anita Break went rock climbing. Anita was able to perform 1370 J of work in 100 seconds. Determine A
Zanzabum

        Power = (energy) / (time)

         =    (1370 joules) / (100 seconds)

         =       13.7  joules/second

         =       13.7 watts .

That's not an awful lot of power, especially for a strenuous activity like
rock-climbing.  Shoot !  Even I could probably perform at that level.

Compare 13.7 watts to the light power coming out of a 20-watt night light.

         13.7 watts  =  0.018 horsepower.      (rounded)

A small, 3 kg weight is moved from 5 m from the ground to 8 m. What is the change in potential energy?
Ulleksa [173]

Answer: 88.2 J

Explanation: PE, OR Potential Energy, equals to mass gravity and height.

mass - 3kg

height - 3 because (8-5)

gravity is 9.8kg

so 3 times 3 times 9.8 = 88.2J
