roteins are denatured by treatment with alkaline or acid, oxidizing or reducing agents, and certain organic solvents. Interesting among denaturing agents are those that affect the secondary and tertiary structure without affecting the primary structure. The agents most frequently used for this purpose are urea and guanidinium chloride. These molecules, because of their high affinity for peptide bonds, break the hydrogen bonds and the salt bridges between positive and negative side chains, thereby abolishing the tertiary structure of the peptide chain.

Answer:

the distance travelled by the traffic, while the car is moving the length of the ramp is 220 m

Explanation:

Given the data in the question;

first we determine acceleration  using the kinematic equation below;

v² - u² = 2as

a = v² - u² / 2s

our initial velocity is zero, v is 19 m/s and distance s is 110 m

so we substitute

a = (19² - 0²) / 2×110

a = 361 / 220

a = 1.6409 m/s²

Next, the time t taken by the car to travel along the length of the ramp will be;

t = v - u / a

we substitute

t = (19 - 0) / 1.6409

t = 11.579 sec

so the distance travelled by a body moving with constant speed u is given by following expression:

s = ut + [tex]\frac{1}{2}[/tex] at²

so we substitute 19 m/s for u, 11.579 sec for t and 0 m/s² for a

s = (19 m/s × 11.579 s) + [tex]\frac{1}{2}[/tex] × 0 × (11.579)²

s = (19 m/s × 11.579 s) + 0

s = 220 m

Therefore, the distance travelled by the traffic, while the car is moving the length of the ramp is 220 m

If the balloon sticks to the wall then electrons move from Pam’s hair to the balloon and attract protons in the wall.

One of the ways of producing static electricity is by the use of friction. Friction occurs when two surfaces are rubbed together. This leads to the loss of electrons from one of the surface which attracts the protons on another surface.

Answer:

Explanation:

To make this problem the easiest way possible, draw a picture and choose the side between the charges. The field will be zero at that point, and I'll prove it in just a second.

[tex]E=\frac{kq}{r^2}[/tex]

k is a constant with a value of [tex]8.99*10^9Nm^2/C^2[/tex]

q is the magnitude of the charge producing the field

r is the distance from the source charge to the test charge

So first determine the electric field from the charge on the bottom left corner, then we'll determine the electric from the bottom right corner.

Convert the centimeters to meters and nano-Coulombs to Coulombs

5cm = 0.05m

2 nC = 2 x 10^-9 C

[tex]E=(8.99*10^9)(2*10^-^9)/(0.025)^2=2.8768*10^4N/C[/tex]

This is pointing to the right because electric field lines point away from positive charges.

[tex]E=(8.99*10^9)(2*10^-^9)/(0.025)^2=-2.8768*10^4N/C[/tex]

This is pointing to the left because of the same reason. Field lines point away from positive charges.

You are able to sum them up because they are both in the x-direction. Their sum will be a net field value of zero.

Answer:

  F = 69.3 N

Explanation:

For this exercise we use Newton's second law, remembering that the static friction force increases up to a maximum value given by

               fr = μ N

We define a reference system parallel to the floor

block B  ( lower)

Y axis  

            N - W₁-W₂ = 0

            N = W₂ + W₂

            N = (M + m) g

X axis

              F -fr = M a

for block A (upper)

X axis

              fr = m a                 (2)

so that the blocks do not slide, the acceleration in both must be the same.

Let's solve the system by adding the two equations

             F = (M + m) a          (3)

             a =[tex]\frac{F}{ M+m}[/tex]

the friction force has the formula

            fr = μ N

             fr = μ (M + m) g

let's calculate

            fr = 0.34 (2.0 + 0.250) 9.8

            fr = 7.7 N

we substitute in equation 2

             fr = m a

             a = fr / m

             a = 7.7 / 0.250

             a = 30.8 m / s²

we substitute in equation 3

             F = (2.0 + 0.250) 30.8

             F = 69.3 N

Frank's 75% efficient light bulb will shine brighter.

Explanation:

The brightness of a bulb is gotten from the power equation;

P = I²R

The more the power rating in watts, the more the brightness.

Now, if they both use the same amount of energy but yet have different efficiency, it means we will just multiply the efficiency by the power.

Thus, 75% efficiency will yield more power than a 45% efficient one.

Therefore, Frank's light bulb will shine brighter.

Answer:

Both charges must have the same charge, Qt/2.

Explanation:

Let the two charges have charge Q1 and Q2, respectively.

Use Coulombs's Law to find an expression for the force between the two charges.

[tex]F = k_e\frac{Q_1Q_2}{r^2}[/tex], where

Ke is Coulomb's contant and

r is the distance between the charges.

We know from the question that

Q1 + Q2 = Qt

So,

Q2 = Qt - Q1

[tex]F = k_e\frac{Q_1(Q_t - Q_1)}{r^2}[/tex]

Simplify to obtain,

[tex]F = \frac{k_e}{r^2} (Q_tQ_1 - Q_1^2)[/tex]

In order to find the value of Q1 for which F is the maximum, we will use the optimization technique of calculus.

Differentiate F with respect to Q1,

[tex]\frac{dF}{dQ_1} = \frac{k_e}{r^2} (Q_t - 2Q_1)[/tex]

Equate the differential to 0, to obtain the value of Q1 for which F is the maximum.

[tex]\frac{k_e}{r^2} (Q_t - 2Q_1) = 0\\Q_t - 2Q_1 = 0\\2Q_1 = Q_t\\Q1 = \frac{Q_t}{2}[/tex]

It follows that

[tex]Q_2 = \frac{Q_t}{2}[/tex].

Explanation:

You have to check a 12 year olds respiration rate by Siting them down and trying to relax.  It's best to take the respiratory rate while sitting up in a chair or in bed.  Measure their breathing rate by counting the number of times their chest or abdomen rises over the course of one minute.  Then Record this number. Now you have to answer the first few  questions based on that.

Heart rate, blood pressure, respiratory rate and temperature are the big four vital signs.

8.  Secondary assessments are used in order to determine the injury, how the injury occurred, how severe the injury is, and to eliminate further injury and that is why it is important.

9. It should only be performed when a person shows no signs of life or when they are unconscious, unresponsive, not breathing or not breathing normally.  

In order to perform CPR, you need to check the scene and the person. Make sure the scene is safe, then tap the person on the shoulder and shout "Are you OK?" to ensure that the person needs help. Then pen the airway,  Check for breathing,  Push hard, push fast, deliver rescue breaths, continue CPR steps.

The normal respiration rate is in the range from 12 to 16 breaths per minute.

The respiration rate is measured when a person is present at rest. For recording the respiration rate, we just count the number of breaths for one minute by counting how many times the chest rises.

The subject’s respiration rate will be considered in a health range if its respiration rate in the range from 12 to 16 breaths per minute.

Exact steps that you take to measure the respiration rate is to count the number of breaths for an entire minute or count for 30 seconds and multiply that number by two. We can measure the respiration rate for about one minute.

DRABC is an abbreviation that stands for Danger, Response, Airway, Breathing and Circulation. Airway, Breathing and Circulation are the parts of DRABC acronym that deal directly with the respiratory system.

A secondary assessment that involves a head-to-toe inspection of the patient is also necessary because it is done to do inspection of the whole body in order to check the physical condition of the patient. CPR should be performed when a person is unconscious, having abnormal breathing and not breathing.

Answer:

1.56×10¯¹⁰ V.

Explanation:

From the question given above, the following data were obtained:

Capicitance (C) = 0.9 MF

Quantity of electricity (Q) = 1.4x10¯⁴ C

Potential difference (V) =?

Next, we shall convert 0.9 MF to farad (F). This can be obtained as follow:

1 MF = 10⁶ F

Therefore,

0.9 MF = 0.9 MF × 10⁶ F / 1 MF

0.9 MF = 9×10⁵ F

Finally, we shall determine the potential difference. This can be obtained as follow:

Capicitance (C) = 9×10⁵ F

Quantity of electricity (Q) = 1.4x10¯⁴ C

Potential difference (V) =?

Q = CV

1.4x10¯⁴ = 9×10⁵ × V

Divide both side by 9×10⁵

V = 1.4x10¯⁴ / 9×10⁵

V = 1.56×10¯¹⁰ V

Therefore, the potential difference is 1.56×10¯¹⁰ V.

Answer:

The kinetic energy of the proton at the end of the motion is 1.425 x 10⁻¹⁶ J.

Explanation:

Given;

initial velocity of proton, [tex]v_p_i[/tex] = 3 x 10⁵ m/s

distance moved by the proton, d = 3.5 m

electric field strength, E = 120 N/C

The kinetic energy of the proton at the end of the motion is calculated as follows.

Consider work-energy theorem;

W = ΔK.E

[tex]W =K.E_f - K.E_i[/tex]

where;

K.Ef is the final kinetic energy

W is work done in moving the proton = F x d  = (EQ) x d = EQd

[tex]K.E_f =EQd + \frac{1}{2}m_pv_p_i^2[/tex]

[tex]m_p \ is \ mass \ of \ proton = 1.673 \ \times \ 10^{-27} kg \\\\Q \ is \ charge \ of \ proton = 1.6 \times 10^{-19} C[/tex]

[tex]K.E_f = 120\times 1.6 \times 10^{-19} \times 3.5 \ + \ \frac{1}{2}(1.673\times 10^{-27})(3\times 10^5)^2 \\\\[/tex]

[tex]K.E_f = 6.72\times 10^{-17} \ + \ 7.53 \times 10^{-17} \\\\K.E_f = 14.25 \times 10^{-17} J\\\\K.E_f = 1.425\times 10^{-16} \ J[/tex]

Therefore, the kinetic energy of the proton at the end of the motion is 1.425 x 10⁻¹⁶ J.
