What force is necessary to accelerate a 1,200 kg car at a rate of 35 m/s2?
How much acceleration would the car have if a 30,600 N force was applied to
the car?

Answers

Answer 1

Explanation:

Given that,

Mass of a car, m = 1200 kg

Acceleration of the car, a = 35 m/s²

The force acting on the car is given by :

F = ma

F = 1200 kg × 35 m/s²

= 42000  N

If the force is 30,600 N, then acecleration is given by :

[tex]a=\dfrac{F}{m}\\\\a=\dfrac{30600}{1200}\\\\a=25.5\ m/s^2[/tex]

Hence, this is the required solution.

1. A 4.00 L sample of air at 35 degrees C expands to 5.50 L when heated. What is

the new temperature, in degrees Celsius, of the air

Answers

Answer:

150.5 °C

Explanation:

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

Initial volume (V₁) = 4 L

Initial temperature (T₁) = 35 °C

Final volume (V₂) = 5.5 L

Final temperature (T₂) =?

Next, we shall convert 35 °C to Kelvin temperature. This can be obtained as follow:

T(K) = T(°C) + 273

Initial temperature (T₁) = 35 °C

Initial temperature (T₁) = 35 °C + 273

Initial temperature (T₁) = 308 K

Next, we shall determine the final (i.e the new) temperature of air. This can be obtained as follow:

Initial volume (V₁) = 4 L

Initial temperature (T₁) = 308 K

Final volume (V₂) = 5.5 L

Final temperature (T₂) =?

V₁ / T₁ = V₂ / T₂

4 / 308 = 5.5 / T₂

Cross multiply

4 × T₂ = 308 × 5.5

4 × T₂ = 1694

Divide both side by 4

T₂ = 1694 / 4

T₂ = 423.5 K

Finally, we shall convert 423.5 K to celsius temperature. This can be obtained as follow:

T(°C) = T(K) – 273

T₂ = 423.5 K

T₂ = 423.5 – 273

T₂ = 150.5 °C

Thus, the new temperature of the air is 150.5 °C

Answers

Answer:

1) Covalent bond, in chemistry, the interatomic linkage that results from the sharing of an electron pair between two atoms. The binding arises from the electrostatic attraction of their nuclei for the same electrons.

2)A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms.

3)Hydrogen (H2), oxygen (O2), and chlorine (Cl2) molecules, for example, each contains two atoms. Another form of oxygen, ozone (O3), has three atoms, and sulfur (S8) has eight atoms. All elemental molecules are made of atoms of a single element.

What is the total amount of heat needed to change 2.25 kg of silver at 0.0°C to 200.0°C? The specific heat of silver is 0.129 J/g·°C (2.25 kg = 2250 g)

Answers

Answer:

Q = 5805 Joules.

Explanation:

Given the following data;

Mass = 2250g

Specific heat capacity of silver = 0.129 J/g·°C

Initial temperature, T1 = 0.0°C

Final temperature, T2 = 200.0°C

To find the quantity of heat needed;

Heat capacity is given by the formula;

[tex] Q = mcdt[/tex]

Where;

Q represents the heat capacity or quantity of heat. m represents the mass of an object. c represents the specific heat capacity of water. dt represents the change in temperature.

dt = T2 - T1

dt = 200 - 0

dt = 200°C

Substituting the values into the equation, we have;

[tex] Q = 225*0.129*200[/tex]

Q = 5805 Joules.

Therefore, the amount of heat needed is 5805 Joules.

The amount of heat needed will be "5805 Joules".

Given values:

Mass, [tex]m = 2250 \ g[/tex]Specific heat capacity, [tex]0.129 \ J/g.^{\circ} C[/tex]Initial temperature, [tex]T_1 = 0.0^{\circ} C[/tex]Final temperature, [tex]T_2 = 200.0^{\circ} C[/tex]then,Change in temperature, [tex]dt = T_2-T_1[/tex]

                                                      [tex]= 200-0[/tex]

                                                      [tex]= 200^{\circ} C[/tex]

As we know the formula,

Heat capacity, [tex]Q = mcdt[/tex]

By substituting the values, we get

                                [tex]= 225\times 0.129\times 200[/tex]

                                [tex]= 5805 \ Joule s[/tex]

Thus the above answer is right.

Explanation:

Answer:

here...

Explanation:

1 - Temperature is a quantitative measure of how hot or cold something is. Temperature is fundamentally linked to the kinetic energy of atom-scale particles. The Celsius scale is based on the older centigrade scale, adapted slightly to take account of the absolute temperature scale, measured in kelvins, symbol K.

2-  Increasing the temperature will cause chemical changes to occur faster. Decreasing the temperature, causes the particles to lose energy which causes them to move around less and slower. The less they move, the less collisions occur, and the less reactions occur between the chemicals = slower reaction rate.

3-  When a system absorbs or loses heat, the average kinetic energy of the molecules will change. Thus, heat transfer results in a change in the system's temperature as long as the system is not undergoing a phase change.

4-  As the temperature increases, the kinetic energy of the molecules of the liquid increases. The movement of the molecules gradually overcomes forces of attraction between the molecules, with the result that they have greater freedom to move, over greater volumes.

5- The kinetic molecular theory of matter states that: Matter is made up of particles that are constantly moving. Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles.

What is the manipulated variable, responding variable, and controlled Variable
observe different electrolytes in a wet cell that will light a
bulb most brightly.

Answers

Answer:

Manipulated/independent variable- DIFFERENT ELECTROLYTES

Responding/dependent variable- BRIGHTNESS OF BULB

Controlled variable- WET CELL

Explanation:

The independent variable, also known as manipulated variable is the variable that the experimenter changes or manipulates in an experiment. In this case where different electrolytes are observed to see which will light a bulb most brightly, the manipulated variable is the DIFFERENT ELECTROLYTES.

Dependent or responding variable is the variable of an experiment that responds to the changes made to the independent variable. It is the variable that is being measured in an experiment. In this case, the BRIGHTNESS OF BULB is dependent on the electrolyte used, hence, it is the responding variable.

Controlled variable or constant is the variable that the experimenter keeps the same throughout the experiment. In this case, the WET CELL is kept constant for all the electrolytes used i.e. it is not changed, hence, the WET CELL is the controlled variable.
