If x and t represent distance and time, respectively, the C in x = (1/2)×C×t² must have the dimensions L/T²

The relationship between time (t) and distance (x) is expressed in the form x = (1/2)×C×t² in the equation x = (1/2)Ct². As a result, the constant C must have the dimensions L/T² or length divided by time squared.

This is due to the fact that the constant C must have dimensions of L/T² in order for the equation to be dimensionally balanced and for x to have the dimensions of distance (L) and t to have the dimensions of time (T).

This is so that the equation, which must have the units of L/T², the units of acceleration, can express the position of a particle traveling in a straight line with a constant acceleration, where C is the constant acceleration.

This is how the equation was analyzed in terms of dimensions. It is a means to check whether the equation is mathematically consistent.

Answer of all the questions about boyle's Law is given below.

Boyle's Law is an important gas law named after Robert Boyle, an Irish physicist and chemist. It states that the pressure and volume of a gas are inversely proportional. This means that when the pressure of a gas increases, its volume decreases, and vice versa. This law is applicable to many real-life situations, such as the effect of altitude on atmospheric pressure and the behavior of gases in a closed system.

(a) The rate of change of volume with respect to pressure can be calculated using the derivative of Boyle's Law. The equation is dV/dP = -C/P2, where C is the constant of the equation.

(b) The volume of the gas is decreasing more rapidly at the beginning of the 10 minutes, as the pressure is much lower. As the pressure increases, the rate of decrease for the volume will become slower, as the pressure and volume are inversely related.

(c) To prove that the isothermal compressibility is given by B=1/P, we can start with the definition of isothermal compressibility: B=–dV/dP(V,T). Using Boyle's Law and the derivative of Boyle's Law, we can substitute the equation to get B=–(C/P2). Rearranging the equation, we get B=1/P. Therefore, the isothermal compressibility is given by B=1/P.

Answer:

Explanation:

To find the speed of the clock at the lowest point in its swing, we can use the formula:

Speed = (distance) / (time)

In this case, the distance is the length of the clock (0.993 m) multiplied by the sine of the maximum angle of the swing (4.57°).

Speed = (0.993 m) x (sin 4.57°)

But we need to keep in mind that the angle needs to be converted to radians before we can use it in the sin function, since the trigonometric functions operate in radians.

So, the first step is to convert the angle from degrees to radians:

4.57° * (π/180) = 0.0799 radians

Now we can plug that angle in the formula,

Speed = (0.993 m) x (sin 0.0799 radians)

This will give us the speed of the clock at the lowest point of its swing.

The pendulum on grandfather clock is 0.993 m long, and swings to maximum 4.57° angle. It is moving at 0.248 m/s, the lowest point in its swing.

A pendulum is a weight suspended from pivot such that it can swing freely. When the pendulum is displaced sideways from its resting position, equilibrium position, then it is subject to a restoring force due to gravity that will accelerate it back towards equilibrium position.

As, m⋅ g⋅ sin(θ)=mv²/(R⋅sinθ)

So, v² = gr sin²Ф

= 9.8 * 0.993 * sin (4.57)

Hence, v= 0.248 m/s

It is moving at 0.248 m/s the lowest point in its swing.

A. The reaction given is PbCO3(s) ⇌ PbO(s) + CO2(g) which is at equilibrium at 410 ∘C.

The equilibrium constant (Kp) for this reaction at that temperature can be found using the data in Appendix C of the textbook.

The value of Kp at 410 ∘C is 1.0 x 10^-5.

To calculate the equilibrium pressure of CO2 in the system at 410 ∘C, we use the following equation:

Kp = [CO2]^(coefficient of CO2 in the balanced equation)

[PbO][CO2]^1 = 1.0 x 10^-5

Since the coefficient of CO2 in the balanced equation is 1, we can substitute the value of Kp into the equation as:

[CO2] = √(Kp) = √(1.0 x 10^-5) = 1.0 x 10^-2.5 = 3.162 x 10^-3

The equilibrium pressure of CO2 in the system at 410 ∘C is 3.162 x 10^-3 atm.

B. For equilibrium pressure of CO2 in the system at 240 ∘C, we can use the Kp value at that temperature which is 1.5 x 10^-7 from the Appendix C.

[CO2] = √(Kp) = √(1.5 x 10^-7) = 1.5 x 10^-3.5 = 2.121 x 10^-4

The equilibrium pressure of CO2 in the system at 240 ∘C is 2.121 x 10^-4 atm.

It should be noted that the values of Kp, pressure and temperature are interrelated in the equilibrium constant equation.

As the temperature decreases, the pressure of CO2 decreases as well.

True. In a head-on collision between two protons, the total momentum of the system must remain the same.

Total momentum is the sum of the momentum of all the objects in a system. Momentum is a vector quantity, meaning it has both magnitude and direction. It is calculated by multiplying the mass of an object by its velocity. In a closed system, the total momentum of the system remains constant, meaning that the momentum of one object increases as the momentum of another decreases. This is known as the law of conservation of momentum. This law states that the total momentum of a system before and after a collision is the same.

Suppose a camera's exposure is correct when the lens has a focal length of 8.0 mm. The picture will be underexposed if the focal length is "zoomed" to 16.0 mm without changing the diameter of the lens aperture.

What does Focal length means?

Focal length is a measurement of a lens that determines how much of a scene is captured in the image. It is measured in millimeters and is calculated by the distance between the lens and the image sensor when the subject is in focus. The shorter the focal length, the wider the angle of view and the more of the scene that is captured.

What is lens aperture?

Lens aperture is the physical size of the opening in a lens that controls the amount of light that passes through the lens to the image sensor. Aperture is usually expressed in terms of f-numbers; the lower the f-number, the wider the aperture and the more light that is allowed to pass through the lens.The size of the aperture also affects the depth of field of an image, which is the range of distances within which objects appear to be in focus.
