Plzzzzzz help me I will mark u brainiest

Can someone help me with number 1 and 2 plz!

Answer:

1) 0 N

2) 8 N

Explanation:

The net force is the sum of all of the forces acting on the object.

For question 1, we can see that there is a force of 5 N acting to the right and 5 N acting to the left. If we define the right to be positive and the left to be negative, then the net force equals:

Fnet = 5N - 5N = 0 N

Therefore, the net force in question 1 is 0 N.

For question 2, the process is very similar. We want to find the sum of the forces acting on the object. In this case, there are forces of 3 N and 5 N acting to the right.

Fnet = 3 N + 5 N = 8 N

Therefore, the net force in question 2 is 8 N.

Hope this helps!

What would be the total volume of the new solution when it is changed from 0.2 M to 0.04 M?

34kurt

The question is incomplete.

You need two additional data:

1) the original volume
2) what solution you added to change the volume.

This is a molarity problem, so remember molarity definition and formula:

M = n / V in liters: number of moles per liter of solution

To give you the key to answer this kind of questions, supppose the original volumen was 1 ml and that you added only water (solvent).

The original solution was:

V= 1 ml
M = 0.2 M

Using the formula for molarity, M = n / V

n = M×V = 0.2 M × (1 / 10000)l = 0.0002 moles

For the final solution:

n = 0.0002 moles
M = 0.04

From M = n / V ⇒ V = n / M = 0.002 moles / 0.04 M = 0.05 l

Change to ml ⇒ 0.05 l × 1000 ml / l = 50 ml. This would be the answer for the hypothetical problem that I assumed for you.

I hope this gives you all the cues you need to answer similar problems about molarity.

g Consider a uniport system where a carrier protein transports an uncharged substance A across a cell membrane. Suppose that at

Alborosie

Answer : The ratio of the concentration of substance A inside the cell to the concentration outside is, 296.2

Explanation :

The relation between the equilibrium constant and standard Gibbs free energy is:

$\Delta G^o=-RT\times \ln Q\\\\\Delta G^o=-RT\times \ln (\frac{[A]_{inside}}{[A]_{outside}})$

where,

$\Delta G^o$ = standard Gibbs free energy = -14.1 kJ/mol

R = gas constant = 8.314 J/K.mol

T = temperature = $25^oC=273+25=298K$

Q = reaction quotient

$[A]_{inside}$ = concentration inside the cell

$[A]_{outside}$ = concentration outside the cell

Now put all the given values in the above formula, we get:

$-14.1\times 10^3J/mol =-(8.314J/K.mol)\times (298K)\times \ln (\frac{[A]_{inside}}{[A]_{outside}})$

$\frac{[A]_{inside}}{[A]_{outside}}=296.2$

Thus, the ratio of the concentration of substance A inside the cell to the concentration outside is, 296.2

How are the parts of a wave related? Describe it and include the formula

KonstantinChe [14]

Different parts of wave include Amplitude,wavelength,period,frequency,time-period,speed,velocity .

Explanation:

Waves are one way in which energy may be transferred. Both mechanical and electromagnetic waves will transfer energy.

When a wave is drawn on a graph the vertical axis is the amplitude of the wave while the horizontal axis can be either distance or time.

The highest point on the graph of the wave is called the crest and the lowest point is called the trough.The line through the center of the wave is the resting position of the medium if there was no wave passing through.

The different properties of a wave include:

Amplitude,wavelength,period,frequency,time-period,speed,velocity etc..

The wavelength of a wave is the distance between two two crests of a wave or two troughs of a wave. The wavelength is usually represented in physics by the Greek letter lambda (λ).

The frequency of a wave is the number of times per second that the wave cycles. Frequency is measured in Hertz or cycles per second and often represented by the lower case "f."

The period of the wave is the time between wave crests. The period is measured in time units such as seconds and is usually represented by the upper case "T".

The period and frequency are closely related to each other. The period equals 1 over the frequency and the frequency is equal to one over the period. They are reciprocals of each other as shown in the following formulas.

period = 1/frequency or T = 1/f

frequency = 1/period or f = 1/T

Another important property of a wave is the speed of propagation. This is how fast the disturbance of the wave is moving. The speed of mechanical waves depends on the medium that the wave is traveling through. For example, sound will travel at a different speed in water than in air.

The velocity of a wave is usually represented by the letter "v". The velocity can be calculated by multiplying the frequency by the wavelength.

velocity = frequency * wavelength or v = f * λ
