Use the **Ideal Gas Law** to find the pressure of the gas under the given conditions:

Where **P** represents pressure, **V** represents volume, **n** represents the amount of substance of the sample, **R** is the universal gas constant and **T** represents the temperature.

The volume and the temperature of the sample are given. On the other hand, we can calculate the amount of substance from the given mass of the sample. The **molar mass M** of a substance is the ratio between the mass of a sample and the amount of substance, and is characteristic of each substance:

A molecule of O₂ is made of two oxygen atoms. The atomic mass of oxygen is approximately **16u**, then, the atomic mass of the molecule of O₂ is **32u**, which means that its **molar mass** is **32 grams per mole**:

Isolate **n** from the equation and replace **m=1g** and **M=32g/mol** to find the amount of substance of the sample:

Now that we have calculated the value of **n**, the only unknown for the Ideal Gas Law is the pressure of the gas. Write the universal gas constant using units of **liters** for the volume:

Isolate **P** from the ideal gas law and replace **V=4.00L**, **n=0.03125mol**, **T=293K** and the value of **R** to find the pressure of the gas:

**Therefore, the pressure of the container will be approximately ****19kPa****.**

Jimmy launches his rocket straight up with an initial velocity of 25 m/s.a. What is the velocity as the rocket reaches maximum height?b. How long will it take the rocket to reach its maximum height?

Given that the initial velocity is u = 25 m/s.

We have to find the final velocity and time at its maximum height.

First, we need to find the maximum height.

[tex]h\text{ =}\frac{u}{2g}[/tex]Here, g = 9.81 m/s^2 is the acceleration due to gravity.

Substituting the values, the height will be

[tex]\begin{gathered} h=\text{ }\frac{25}{2\times9.81} \\ =1.274\text{ m} \end{gathered}[/tex](a) Let the final velocity be v.

The formula to calculate final velocity is

[tex]\begin{gathered} v^2=u^2-2gh^{} \\ v=\sqrt[]{u^2-2gh^{}} \end{gathered}[/tex]Substituting the values, the final velocity will be

[tex]\begin{gathered} v=\sqrt[]{\lbrack(25)^2-(2\times9.81\times1.274)\rbrack} \\ =\sqrt[]{600.01} \\ =24.49\text{ m/s} \end{gathered}[/tex](b) The time taken can be calculated by the formula,

[tex]\begin{gathered} t=\frac{v-u}{-g} \\ =\frac{24.49-25}{-9.81} \\ =0.051\text{ s} \end{gathered}[/tex]Thus, the final velocity is 24.49 m/s and time is 0.051 s

In (Figure 1) a 6.00-m-long, uniform beam is hanging from a point 1.00 m to the right of its center. The beam weighs 155 N and makes an angle of 30.0∘ with the vertical. At the right-hand end of the beam a 100.0 N weight is hung; an unknown weight w hangs at the left end.If the system is in equilibrium, what is w ? You can ignore the thickness of the beam.

Given::

Length = 6.00 m

Weight of beam = 155 N

Angle = 30.0 degrees

Weight added at the right-end = 100 N

If the system is in equilibrium, let's find the weight, w, at the left-end.

Since the system is in equilibrium, the net torque of the system will be zero.

Now, we have the equation:

[tex](100)(2.00sin30)-w(4.00sin30)-(155)(1.0sin30)=0[/tex]Where w is the weight at the left end.

Let's solve for w.

We have:

[tex]\begin{gathered} (100)(1)-w(2)-(155)(0.5)=0 \\ \\ 100-2w-77.5=0 \\ \\ 100-77.5-2w=0 \end{gathered}[/tex]Solving further:

[tex]\begin{gathered} 22.5-2w=0 \\ \\ 2w=22.5 \end{gathered}[/tex]Divide both sides by 2:

[tex]\begin{gathered} \frac{2w}{2}=\frac{22.5}{2} \\ \\ w=11.25\text{ N} \end{gathered}[/tex]**Therefore, the weight hung at the left end is 11.25 N**

A helium balloon has a volume of 8.89 liters, or 0.00889 cubic meters. Air has a density of 1.29 kilograms per cubic meter, and helium has a density of 0.177 kilograms per cubic meter.a. What is the weight of the helium inside the balloon?b. What is the buoyant force exerted on the balloon?c. What is the net force on the balloon? Neglect the weight of the rubbery material that comprises the actual balloon. . How many identical balloons would be needed to lift a child of mass 24.9 kilograms?

**Given:**

The volume of a helium balloon: 8.89 liters or 0.00889 cubic meters

The density of helium: 0.177 kilograms per cubic meters

The density of the air: 1.29 kilograms per cubic meters

**To find:**

a) weight of the helium inside the balloon.

b) the buoyant force exerted on the balloon.

c) the net force on the balloon.

d) number of identical balloons needed to lift a child of mass 24.9 kilograms.

**Explanation:**

**a)**

The expression for the density of the balloon is:

[tex]Density\text{ of helium=}\frac{Mass\text{ of helium}}{Volume\text{ of helium}}[/tex]Rearrange the above expression to find the mass of the helium.

[tex]Mass\text{ of helium=Density of helium}\times Volume\text{ of helium}[/tex]Substitute the values from the given data, we get:

[tex]\begin{gathered} Mass\text{ of helium=0.177}\frac{kg}{m^3}\times0.00889\text{ m}^3 \\ Mass\text{ of helium=0.001573 kg} \end{gathered}[/tex]Thus, the mass of the helium is 0.001573 kg.

The weight of an object is the product of its mass and gravitational acceleration. Thus, the weight of helium is

[tex]\begin{gathered} Weight\text{ of helium=mass of helium}\times g \\ \end{gathered}[/tex]here, g is the acceleration due to gravity.

Substitute the values, and we get:

[tex]\begin{gathered} Weight\text{ of helium=0.001573 kg }\times9.8\text{ }\frac{m}{s^2} \\ Weight\text{ of helium=0.01542 N} \end{gathered}[/tex]The weight of helium is 0.001542 Newtons.

**b)**

The expression for buoyant force is:

[tex]F=\rho gV[/tex]here, ρ is the density, g is the acceleration due to gravity and V is the volume.

To find the buoyant force exerted by helium on the balloon, substitute the values for helium in the above equation.

[tex]\begin{gathered} F=0.177\text{ }\frac{kg}{m^3}\times9.8\text{ }\frac{m}{s^2}\times0.00889\text{ m}^3 \\ F=0.01542\text{ }\frac{kg\cdot m}{s^2} \\ F=0.01542\text{ N} \end{gathered}[/tex]The buoyant force exerted on the baloon is 0.01542 Newtons.

**c) **

The buoyant force exerted by the balloon is 0.01542 N and it acts in an upward direction. Whereas, the other force acting on the balloon is the force due to gravity, the weight of the balloon. The weight of the balloon is 0.01542 N and is always acts in the downwards direction.

Since the magnitude of buoyant force exerted on a balloon is equal to the weight of the balloon. Both these forces are acting in opposite directions. Thus the net effect will be zero.

[tex]\begin{gathered} F_{net}=F-W \\ F_{net}=0.01542\text{ N -0.01542 N} \\ F_{net}=0\text{ N} \end{gathered}[/tex]Thus, the net force acting on the balloon is 0 Newtons.

**d)**

For a helium balloon, 1 liter of helium can lift 1 gram of mass.

The mass of the child is 24.9 kg = 24900 grams.

Thus, to lift a child of mass 24900 grams, 24900 liters of helium is required.

Now, one balloon contains 8.89 liters of helium, thus for 24900 liters of helium volume, the number of ballons required will be,

[tex]\frac{1\text{ balloon}}{n\text{ balloons}}=\frac{8.89\text{ liters}}{24900\text{ liters}}[/tex]Rearranging above equation to find n, we get

[tex]\begin{gathered} n\text{ balloons = }\frac{24900}{8.89} \\ n\text{ balloons = 2800.89} \end{gathered}[/tex]Thus, approximately 2801 helium balloons are required to lift a child of mass 24.9 kg.

**Final answer**:

**a) The weight of helium is 0.001542 Newtons.**

**b) The weight of helium is 0.001542 Newtons.**

**c) The net force acting on the balloon is 0 Newtons.**

**d) Approximately 2801 helium balloons are required to lift a child of mass 24.9 kg.**

A particular cookie provides 54.0 kcal of energy. An athlete does an exercise that involves repeatedly lifting (without acceleration) a 103-kilogram weight 2.45-decimeters above the ground with an energy efficiency of 25%. How many repetitions of this exercise can the athlete do with the energy supplied from one of these cookies?

The maximum quantity of **repetitions** that the athlete could complete with their current level of energy was 229 for such a workout.

**Energy efficiency** is the ratio of input power to energy output. As just a result, a cookie contains 54.0 kcal in calories. An athlete utilizes the 54.0 kcal in just this cookie for input energy.

The following formula could be employed to measure efficiency:

Energy intake minus power generated is efficiency.

Efficiency = output energy / **input energy**

After rearrangement above equation.

**output energy** = efficiency × input energy

Put the given data in above equation.

Output energy = 0.25 × 54 kcal = 13.5 kcal.

Again for **power capacity,** the lifting exercise was already carried out n times. The source of total output energy is mgh within the form of electromagnetic potential.

So, Energy per repetition = mgh

Where, m will represent mass g will represent gravity h is height.

By entering the data provided above.

**Energy per repetition **= 103 kg × 9.8 m/[tex]s^{2}[/tex] × (2.45 × 0.1m)

Energy per repetition= 247.303 J

Energy per repetition = 0.059 kcal.

So, quantity of repetitions = overall output energy / energy per repetition

quantity **of repetitions** = 13.5 kcal / 0.059 kcal

quantity of repetitions will be equal to 229 repetitions.

Therefore, the quantity of repetition would be be 229.

A shopper in a supermarket pushes a loaded cart with a horizontal force of 14 N. The cart

has a mass of 32 kg.

The acceleration of gravity is 9.8 m/s

2

.

Disregarding friction, how far will the cart

move in 4 s, starting from rest?

Answer in units of m.

**Answer:**

ΔS = 3.5 m

**Explanation:**

First, apply the 2º Newton's Law to find the resulting acceleration.

∑**F** = m × **a**

F = m × a

14 = 32 × a

a = 14 /32 = 7/16

a = 0.4375 m/s²

Then, we must apply the equation of accelerated movement:

ΔS = V₀*t + (1/2)*a*t²

Starting from the rest and using the value of acceleration:

ΔS = 0*4 + (1/2)*(0.4375)*(4)²

ΔS = (1/2)*(0.4375)*(16)

ΔS = 3.5 m
