Answer:

8N is the net force on the object.

Explanation:

Given that,

\mathrm{F}_{\text {norm }}=20N is normal force acting upward (+20N)

F_{\text {frict }}=14N is frictional force which is opposite to the applied force (-14N)

\mathrm{F}_{\mathrm{app}}=22N is applied force which is applied on right side (+22N)

\mathrm{F}_{\mathrm{grav}}=20N is gravitational force acting downward (-20N)

We know that ,

\text { Fnet }=applied force \left(\mathrm{F}_{\mathrm{app}}\right)+frictional force\left(F_{\text {frict }}\right)+normal force \left(\mathrm{F}_{\mathrm{norm}}\right)+gravitational force \left(F_{\text {grav}}\right)

\mathrm{F}_{\mathrm{net}}=22+(-14)+ 20+(-20)

\mathrm{F}_{\mathrm{net}}=22-14+20-20

\mathrm{F}_{\mathrm{net}}=8 \mathrm{N}

Therefore the net force of the object be 8N.

kumpel [21]

Answer:

Graph C

Explanation:

With the same force and more mass, the position in time will still be parabolic

i.e.  x = ½at², but the rate of acceleration will be lower so the position curve will be broader.

Thank you for posting your question here at brainly. Below is the solution. I hope the answer will help. 

<span>Cl^- 1s^2 2s^2p^6 3s^2 3p^6 1s^2 2s^2p^6 S = 10; 3s^2 3p^6 S = 0 </span>
<span>Zeff = Z-S = 17- 10 =7 </span>
<span>K^+ 1s^2 2s^2p^6 3s^2 3p^6; 1s^2 2s^2p^6 S = 10; 3s^2 3p^6 S = 0 </span>
<span>Zeff = Z-S = 19- 10 = 9 
</span>
S = 2 + 6.8 + 2.45 = 11.25 
<span>Zeff(Cl^-) = 17 – 11.25 = 5.75 </span>
<span>K^+ 1s^2 2s^2p^6 3s^2 3p^6 same S as for Cl^- but Z increases by 2 hence </span>
<span>Zeff(K^+) = 19 - 11.25 = 7.75</span>

Which data set has the smallest standard deviation?
hjlf

Answer:

B. 22,22,23,23,22,22,23

Explanation:

The standard deviation is a measure of dispersion or variability of a data set. In order to determine the data set that has the smallest standard deviation, we shall investigate on the ranges of the data sets given. The range of a data set is simply the difference between the maximum and minimum values in a data set. A data set that has a smaller range also has a smaller standard deviation.

From the alternatives given, the data set given by alternative B has the smallest range and consequently the smallest standard deviation.

The maximum value is 23 while the minimum is 22. The range is 1.
