The battery on your car has a rating stated in ampere minute which permit you to estimate the length of time a fully charged battery could deliver any particular current before discharge. Approximately how much energy is stored by a 50 ampere minute 12 volt battery

A. The work done by the gas enclosed in a cylinder equipped with a light, frictionless piston and maintained at atmospheric pressure, when 254 Kcal of heat is added to the gas, its volume increases slowly from 12.0 m³ to 16.2 m³ = 420 x 10³ kal.

B. The change in internal energy = 6.74 x 10⁵ Joule.

The concept of thermodynamics is an attempt to convert heat into energy, including the process of the flow of energy and the consequences produced by the transfer of energy.

The first law of thermodynamics is an example of the law of the conservation of energy. That is, energy cannot be created and cannot be destroyed. Energy can only change from one form to another. The first law of thermodynamics states that for every process if heat (Q) is given to the system and the system does work (W), there will be a change in internal energy (ΔU).

The equation is:

ΔE = Q + W

ΔU : change in internal energy (Joule)

Q: the amount of heat (Joule)

W: system work (Joule)

We have,

P = 10⁵ ⇒ atmospheric pressure

Q = 254 Kcal = 254 x 10³

ΔV = 16.2 m³ - 12.0 m³

= 4.2 m³

So, the work done by the gas:

W = PΔV

= (10⁵) (4.2)

= 420 x 10³ kal

And, the change in internal energy:

ΔE = Q + W

= (254 x 10³) + (420 x 10³)

= 6.74 x 10⁵ Joule

1. the tire pressure monitor on your car lights up on a cold winter day

2. a balloon popping as it is taken up a mountain

To determine the angle through which the wheel rotates in 1.00 second, we can start by finding the angle covered in 0.0710 seconds and then scale it up to 1.00 second.

In 0.0710 seconds, the wheel completes 3.10 revolutions. One revolution corresponds to an angle of 360 degrees or 2π radians. Therefore, in 0.0710 seconds, the wheel rotates through an angle of:

Angle = 3.10 revolutions * 2π radians/revolution = 6.20π radians

To find the angle in 1.00 second, we can use proportional reasoning. Since the time increases by a factor of 1.00/0.0710, the angle covered will also increase by the same factor:

Angle in 1.00 second = 6.20π radians * (1.00/0.0710) = 87.32π radians

Approximately, the angle through which the wheel rotates in 1.00 second is 274.39 radians.

Therefore, the wheel rotates through an angle of approximately 274.39 radians in 1.00 second.

In a DC generator, the generated electromotive force (emf) is directly proportional to the rotational speed of the generator's armature and the strength of the magnetic field within the generator.

This relationship is described by the equation for the generated emf in a DC generator:

Emf = Φ * N * A * Z / 60

Where:

Emf is the generated electromotive force (in volts),

Φ is the magnetic flux density (in Weber/meter^2\(meter^2\) or Tesla),

N is the number of turns in the armature winding,

A is the effective area of the armature coil (in square meters),

Z is the total number of armature conductors, and

60 is a constant representing the conversion from seconds to minutes.

From this equation, we can see that the generated emf is directly proportional to the magnetic flux density (Φ) and the product of the number of turns (N), effective area (A), and the total number of armature conductors (Z). This means that increasing any of these factors will result in a higher generated emf.

The magnetic flux density (Φ) can be increased by using stronger permanent magnets or increasing the strength of the field windings in the generator.

The number of turns (N) and the effective area (A) are design parameters and can be optimized for a specific generator. Increasing the number of turns or the effective area will result in a higher generated emf.

Similarly, the total number of armature conductors (Z) can be increased to enhance the generated emf.

By controlling and optimizing these factors, the generated emf in a DC generator can be increased, resulting in higher electrical output. However, it is important to note that there are practical limits to these factors based on the design and construction of the generator.

Answer: Speed = \(3.10^{-31}\) m/s

Explanation: Like in classical physics, when external net force is zero, relativistic momentum is conserved, i.e.:

\(p_{f} = p_{i}\)

Relativistic momentum is calculated as:

p = \(\frac{mu}{\sqrt{1-\frac{u^{2}}{c^{2}} } }\)

where:

m is rest mass

u is velocity relative to an observer

c is light speed, which is constant (c=\(3.10^{8}\)m/s)

Initial momentum is zero, then:

\(p_{f}\) = 0

\(p_{1}-p_{2}\) = 0

\(p_{1} = p_{2}\)

To find speed of the heavier fragment:

\(\frac{mu_{1}}{\sqrt{1-\frac{u^{2}_{1}}{c^{2}} } }=\frac{mu_{2}}{\sqrt{1-\frac{u^{2}_{2}}{c^{2}} } }\)

\(\frac{1.86.10^{-27}u_{1}}{\sqrt{1-\frac{u^{2}_{1}}{(3.10^{8})^{2}} } }=\frac{3.10^{-28}.0.844.3.10^{8}}{\sqrt{1-\frac{(0.844c)^{2}}{c^{2}} } }\)

\(\frac{1.86.10^{-27}u_{1}}{\sqrt{1-\frac{u^{2}_{1}}{(3.10^{8})^{2}} } }=1.42.10^{-19}\)

\(1.86.10^{-27}u_{1} = 1.42.10^{-19}.{\sqrt{1-\frac{u^{2}_{1}}{(3.10^{8})^{2}} } }\)

\((1.86.10^{-27}u_{1})^{2} = (1.42.10^{-19}.{\sqrt{1-\frac{u^{2}_{1}}{(3.10^{8})^{2}} } })^{2}\)

\(3.46.10^{-54}.u_{1}^{2} = 2.02.10^{-38}.(1-\frac{u_{1}^{2}}{9.10^{16}} )\)

\(3.46.10^{-54}.u_{1}^{2} = 2.02.10^{-38} -[2.02.10^{-38}(\frac{u_{1}^{2}}{9.10^{16}} )]\)

\(3.46.10^{-54}.u_{1}^{2} = 2.02.10^{-38} -2.24.10^{-23}.u^{2}_{1}\)

\(3.46.10^{-54}.u_{1}^{2}+2.24.10^{-23}.u^{2}_{1} = 2.02.10^{-38}\)

\(2.24.10^{-23}.u^{2}_{1} = 2.02.10^{-38}\)

\(u^{2}_{1} = \frac{2.02.10^{-38}}{2.24.10^{-23}}\)

\(u_{1} = \sqrt{9.02.10^{-62}}\)

\(u_{1} = 3.10^{-31}\)

The speed of the heavier fragment is \(u_{1} = 3.10^{-31}\)m/s.

4.44×\(10^{9}\) kg/s is the rate at which the sun mass is decreasing.

The Sun radiates energy through a process called nuclear fusion, where hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the process. According to Einstein's mass-energy equivalence principle (E=mc²), this energy release corresponds to a decrease in mass.

To calculate the rate at which the Sun's mass is decreasing, we can use the formula ΔE = Δmc², where ΔE is the change in energy, Δm is the change in mass, and c is the speed of light.

Given that the Sun radiates energy at a rate of 4×10^26 W, we can substitute this value into the equation as ΔE and solve for Δm.

ΔE = 4×10^26 W

c = 3×10^8 m/s (speed of light)

Using the equation ΔE = Δmc² and rearranging it, we get Δm = ΔE / c².

Substituting the values, we have:

Δm = (4×10^26 W) / (3×10^8 m/s)²

Evaluating this expression, we find that the rate at which the Sun's mass is decreasing is approximately 4.44×10^9 kg/s.

This calculation demonstrates that the Sun's mass is gradually decreasing as it continuously radiates energy into space, primarily through the process of nuclear fusion in its core.

Explanation:

When a star has reached the main sequence stage, hydrogen is converted into helium by nuclear fusion, . Also, the gravity and pressure are balanced because the star does not radiate more heat than it generates. A star usually spends most of its lifetime at this stage.

Coefficient of Kinetic Friction = 0.2

Mass of the crate = 1000 kg

Force applied = 2000 N

Normal force is the force applied on the object by the surface. It is equal and opposite to the force of gravity

So, we can say that Normal force = | Gravitational Force |

Normal Force = | mg |

Normal Force = 1000 * 9.8

Normal Force = 9800 N

We know that:

coefficient of Kinetic friction = Friction force / Normal force

replacing the known values

0.2 = Friction force / 9800

Friction Force=  0.2 * 9800

Friction Force = 1960 N

We know that a force of 2000 N is being applied on the crate in the Horizontal direction

Frictional force is always opposite to the horizontal force. So, we can say that:

Applied force - Friction Force = Net Force

replacing the variables

2000 - 1960 = Net force

Net Force = 40N

Therefore, a net force of 40N is being applied on the Crate

From newton's second law of motion:

F = ma

replacing the variables

40 = 1000 * a

a = 40/1000

a = 0.04 m/s²

Answer:

The resonating frequency of the given RLC circuit is found to be 1.59 KHz

Explanation:

The resonating frequency in a series RLC circuit is the one at which the Inductive Reactance and the Capacitive Reactance of the circuit becomes equal. And the circuit becomes purely resistive. The resonating frequency of a series RLC circuit is given by the following formula:

fr = 1/2π√(LC)

where,

fr = Resonating Frequency = ?

L = Inductance = 2 mH = 2 x 10⁻³ H

C = Capacitance = 5 μF = 5 x 10⁻⁶ F

Therefore,

fr = 1/2π√[(2 x 10⁻³ H)(5 x 10⁻⁶ F)]

fr = 1591.5 Hz = 1.59 KHz

The resonating frequency of the given RLC circuit is found to be 1.59 KHz

The statement that describes the transformation of the graph of function f onto the graph of function g is: The graph shifts 2 units right and 7 units down.

To determine the transformation of the graph of function f onto the graph of function g, we compare the two functions f(x) and g(x) and observe the changes in the equations.

The function f(x) = (1/x - 3) + 1 represents a reciprocal function that is shifted vertically 1 unit up and horizontally 3 units to the right. The reciprocal function is reflected about the line y = x.

The function g(x) = (1/(1 + 4)) + 3 simplifies to g(x) = 4 + 3 = 7, which is a constant function representing a horizontal line at y = 7.

By comparing the equations, we can see that the transformation from f(x) to g(x) involves the following changes:

The term 1/x in f(x) is replaced by the constant 1/(1 + 4) in g(x), resulting in a vertical shift of 7 units up.

The term -3 in f(x) is replaced by 3 in g(x), resulting in a vertical shift of 3 units up.

The +1 in f(x) is replaced by +3 in g(x), resulting in an additional vertical shift of 2 units up.

Therefore, the overall transformation is a shift of 2 units to the right and 7 units down.

Hence, the correct statement is: The graph shifts 2 units right and 7 units down.

The coefficient of restitution between two objects is a measure of the elasticity of the collision between them.

It is defined as the ratio of the relative velocity of separation to the relative velocity of approach between the two objects.

In this problem, the velocity of block b after the impact is observed to be 2.2 m/s to the right. Let us assume that block a is moving to the left with a velocity of v1 just before the impact. According to the law of conservation of momentum, the total momentum of the two blocks before the impact is equal to the total momentum of the two blocks after the impact. Therefore:

\(m1v1 + m2v2 = m1v1' + m2v2'\)

where m1 and m2 are the masses of block a and block b, respectively, v1 and v2 are the velocities of block a and block b just before the impact, and v1' and v2' are their velocities just after the impact.

Since block b is moving to the right after the impact, we can take v2' = 2.2 m/s. We also know that the two blocks stick together after the impact, so v1' = v2'. Therefore, we can simplify the above equation to:

\(m1v1 + m2v2 = (m1 + m2)v1'\)

Solving for v1', we get:

\(v1' = (m1v1 + m2v2)/(m1 + m2)\)

The coefficient of restitution (e) is defined as the ratio of the relative velocity of separation (v2' - v1') to the relative velocity of approach (v1 - v2) between the two blocks. Since the two blocks stick together after the impact, the relative velocity of separation is zero. Therefore:

\(e = (v2' - v1')/(v1 - v2) = 0/(v1 - v2) = 0\)

Hence, the coefficient of restitution between the two blocks is zero.
