accelerates at -3.4 m/s2 what is the net force acting on the race car?

a) -541 N

b) 630 N

c) -1.8 N

d) -6,256 N

Answers

The answer is A sorry if it’s wrong

Push and pull subjected to an object is called force and is given in newtons. The net force acting on the race car is -6,256 N.

What is force?

Force is the product of the mass of the object in kg and the acceleration in meters per second square. It is given by the formula:

[tex]\rm F = m \times a[/tex]

Given,

Mass of the race car = 1,840 kg

Acceleration of the race car = -3.4

Substituting values in the above equation:

[tex]\begin{aligned} \rm F &= \rm m \times a \\\\&= 1840 \times -3.4\\\\&= -6,256 \;\rm N \end{aligned}[/tex]

Therefore, option D. -6,256 N is the force acting on the car.

What is the mole ratio of sodium to sodium chloride?

Answers

Answer: The mole ratio of sodium to sodium chloride 2:2.

Explanation:

As the given reaction equation is as follows.

[tex]2Na + Cl_{2} \rightarrow 2NaCl[/tex]

Here, 2 moles of sodium reacts with 1 mole of [tex]Cl_{2}[/tex] and leads to the formation of 2 moles of NaCl.

This means that 2 moles of sodium gives 2 moles of NaCl on reaction with chlorine.

Hence, the ratio of moles of sodium to sodium chloride is 2:2.

Thus, we can conclude that the mole ratio of sodium to sodium chloride 2:2.

Fractional distilation of liquid air usually produces nitrogen and oxygen as major products . Substance used to remove carbon iv oxide from air before its changed to liquid

Answers

Answer:

Caustic soda

Explanation:

The fractional distillation of air is carried out on liquid air. Before air is liquified, the carbon dioxide content of air is removed using caustic soda. The air is then compressed to a pressure of about 200 atm, sudden expansion of the gas leads to cooling. The process continues until air becomes liquid at  -200°C.

Fractional distillation of liquid air usually produces nitrogen and oxygen as major products. nitrogen in obtained first since it has a lower boiling point than oxygen. The gases are then dried, compressed and stored in cylinders.

Molarity = moles of solute/volume of solution in liters.

The solute here is NaCl, of which we have 46.5 g. To calculate the molarity of an NaCl solution, we need to know the number of moles of NaCl. To convert from grams to moles, we divide the mass by the molar mass of NaCl. The molar mass of NaCl is the sum of the atomic masses of Na and Cl: 23 amu + 35 amu = 58 amu. For our purposes, we can regard amu as equivalent to grams/mole.

(46.5 g)/(58 g/mol) = 0.8017 moles NaCl.

Now that we know both the number of moles of our NaCl solute and the volume of the solution, we can calculate the molarity:

(0.8017 moles NaCl)/(2.2 L) = 0.364 M.

The molarity of this solution would be 2.0 M.

What is the specific heat of a 22.8 g sample of metal that absorbs 1,450 Joules of heat from 21.8 degrees Celsius to 75.0 degrees Celsius?

Answers

Answer: The specific heat of given metal is [tex]1.195 J/^{o}C[/tex].

Explanation:

Given: Mass of sample = 22.8 g

Heat energy = 1450 J

Initial temperature = [tex]21.8^{o}C[/tex]

Final temperature = [tex]75^{o}C[/tex]

Formula used to calculate the specific heat is as follows.

[tex]q = m \times C \times (T_{2} - T_{1})[/tex]

where,

q = heat energy

m = mass of substance or sample

C = specific heat

[tex]T_{1}[/tex] = initial temperature

[tex]T_{2}[/tex] = final temperature

Substitute the values into above formula as follows.

[tex]q = m \times C \times (T_{2} - T_{1})\\1450 J = 22.8 g \times C \times (75 - 21.8)^{o}C\\C = \frac{1450 J}{22.8 \times 53.2^{o}C}\\= 1.195 J/^{o}C[/tex]

Thus, we can conclude that the specific heat of given metal is [tex]1.195 J/^{o}C[/tex].

Where:

P₁ = 0.98 barV₁ = 25 mLP₂ = 1.013 barV₂ = ?

We input the data:

0.98 bar * 25 mL = 1.013 bar * V₂

A Pitot-static probe is used to measure the speed of an aircraft flying at 3000 m. If the differential pressure reading is 3100 N/m2, determine the speed of the aircraft in m/s. The density of air at an altitude of 3000 m is 0.909 kg/m3. The speed of the aircraft is km/h.

Answers

Answer:

82.59 m/s or 297.324 km/h

Explanation:

From the question,

Applying

V = √[2(P'/ρ)].................. Equation 1 ( From

Where V = Speed of the aircraft, Differential Pressure of the air craft, ρ = Density of air at an altitude of 3000 m.

Given: P' = 3100 N/m², ρ = 0.909 kg/m³

Substitute into equation 1

V = √[2(3100/0.909)]

V = √(2×3410.34)

V = √(6820.68)

V = 82.59 m/s

V = 297.324 km/h

Hence the speed of the aircraft is  82.59 m/s or 297.324 km/h

pb(No3)2(aq) +2KCI(aq)---PbCl2(s)+KNO2(aq). how many grams of PbCl2 solution will react with a 0.46 L of a 0.101m KCI solution​

Answers

Answer:

6.3986g

Explanation:

The balanced chemical equation of this reaction is as follows:

Pb(NO3)2(aq) + 2KCl (aq) → PbCl2(s) + 2KNO3(aq)

In this equation, 2 moles of KCl solution will produce 1 mole of PbCl2.

To calculate the number of moles of PbCl2 produced, we use the formula:

Molarity = number of moles (n) ÷ volume (V)

0.101 = n/0.46

n = 0.046mol of KCl

If 2 moles of KCl solution will produce 1 mole of PbCl2

Then, 0.046mol of KCl will be react to produce (0.046 × 1/2) of PbCl2

0.046 × 1/2 = 0.023mol of PbCl2

To find the mass of PbCl2 using mole = mass ÷ molar mass

Molar mass of PbCl2 = 207.2 + 35.5(2)

= 207.2 + 71

= 278.2g/mol

0.023 = mass/278.2

mass = 6.3986g
