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

dedylja [7]

Answer

Mean

Explanation

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

There three types of central tendency mean, median and mode.

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.

The 1.5kg ball is launched straight upward with an initial velocity of 7m/s. What is the maximum height it will reach?

Temka [501]

Answer:

h = 2.5 m

Explanation:

Given that,

Mass of a ball, m = 1.5 kg

Initial velocity of the ball, u = 7 m/s

We need to find the maximum height reached by the ball. Let it is be h. Using the conservation of energy to find it such that,

$mgh=\dfrac{1}{2}mu^2\\\\h=\dfrac{u^2}{2g}$

Put all the values,

$h=\dfrac{7^2}{2\times 9.8}\\\\=2.5\ m$

So, it will reach to a height of 2.5 m.

A single conservative force Fx = (6.0x  12) N (x is in m) acts on a particle moving along the x axis. The potential energy asso

jasenka [17]

Answer:

$U(3)=-43J$

Explanation:

Potential energy is minus the integral of Fdx. Doing the integration yields:

$U=\int\limits {6.0x+12}\, dx$

$U=-3x^2-12x+C$

$U(0)=20J$

$U(0)=-3(0)^2+12(0)+C=20$

$C=20$

Now for x=3.0m

$U(3)=-3*(3)^2-12(3)+20$

$U(3)=-43J$

if the radius of the capillary tube is doubled, what changes will take place in the hieght of rise of liquid with capacity tube

tangare [24]

Explanation:

The height of the rise of liquid with capillary tube is given by the formula as follows :

$h=\dfrac{2S\cos\theta}{r\rho g}$

Where

r is radius

It is clear that the height of the rise of liquid is inversely proportional to the radius of the capillary tube.

If the radius of the capillary tube is doubled, it means the height of rise of liquid with capillary tube become half.
