The speed of a 2. 0-kg object changes from 30 m/s to 40 m/s during a 5. 0-s time interval. During this same time interval, the v

abruzzese [7]

The magnitude of the average total force acting on the object during this time interval is equal to 20 Newton.

<u>Given the following data:</u>

Mass = 2.0 kg

Initial velocity = 30 m/s

Final velocity = 40 m/s

Time = 5.0 seconds.

Angle = 90°

To calculate the magnitude of the average total force acting on the object during this time interval:

<h3>Newton's Second Law of Motion</h3>

In order to solve for the force acting on the dummy, we would apply Newton's Second Law of Motion.

<u>Note:</u> The acceleration of an object is equal to the rate of change in velocity with respect to time.

Mathematically, Newton's Second Law of Motion is given by this formula;

$F = \frac{M(v\;-\;u)}{t}$

Substituting the given parameters into the formula, we have;

$F_A = \frac{2(30\;-\;0)}{5}\\\\F_A = \frac{2\times 30}{5}\\\\F_A = \frac{60}{5}$

Force A = 12 Newton.

<u>For the second force:</u>

$F_B = \frac{2(40\;-\;0)}{5}\\\\F_B = \frac{2\times 40}{5}\\\\F_B = \frac{80}{5}$

Force B = 16 Newton.

Now, we can calculate the magnitude of the average total force acting on the object during this time interval:

$F = \sqrt{F_A^2 + F_B^2} \\\\F = \sqrt{12^2 + 16^2}\\\\F = \sqrt{144 + 256}\\\\F=\sqrt{400}$

Total force = 20 Newton.

Mendel's inheritance laws can be used to show the principle of independent segregation and dominance between alleles.

<h3>What are Mendel's inheritance laws?</h3>

Mendel's inheritance laws (or mendelian laws) are two inheritance rules that were discovered by Gregor Mendel working in pea.

Mendel's inheritance law of independent segregation states alleles from different loci segregate in an independent mode.

Mendel's inheritance law of dominance indicates that alleles can be expressed or masked according to their dominance levels.

In conclusion, Mendel's inheritance laws can be used to show the principle of independent segregation and dominance between alleles.

a recycling company gives you 5 cents for every plastic bottle and 10 cents for every glass bottle. from a certain individual th

jeka57 [31]

So Let's Considered No. of Plastic Bottles be a and No. of Glass Bottles be b

So a+b=59
Also a+2b=91

Lets Subtract Equations We get

so b=32

Also a=27 (After Solving)

Hence The Individual Recieved 32 Glass and 27 Plastic Bottles

Consider a buffer made by adding 132.8 g of nac₇h₅o₂ to 300.0 ml of 2.31 m hc₇h₅o₂ (ka = 6.3 x 10⁻⁵) what is the ph of the buffe

sertanlavr [38]

The ph of the buffer solution given after 0.750 mol of H⁺ have been added is; 4.34

<h3>What is the PH of the Buffer?</h3>

pKa = -log(Ka) = 4.20

[A⁻] = [NaC₇H₅O₂]

[HA] = [HC₇H₅O₂]

Concentration of NaC₇H₅O₂ in the preferred buffer solution is;

[132.8g/(144.11 g/mol * 300 mol)] * 1000 mL/1 L = 3.07 M

Formula for the PH here is;

pH = pKa + log [A⁻/HA]

Thus;

pH = -log(6.3 x 10⁻⁵) + log [3.07/2.31]

pH = 4.34
