Explanation:

The half-life of a substance is the time the substance takes to decay until the amount of the sample is half of its initial amount.

In this problem, the half-life of iodine-131 is 8 days. This means that after 8 days, only half of the initial sample will be left. After another 8 days (16 days), the sample will be reduced by another factor 1/2, so only 1/4 of the initial sample will be left.

Since the initial sample was 0.96 g, after 16 days the amount of iodine left is m = 1(0.96g) = 0.24g

Answer:

24 days

Explanation:

This is because the half-life is eight days. If you add another half-life, which will be 16 days, 1/4 of the sample remains, and if you add another half-life which is 24 days, 1/8 will remain.

If the power line frequency is 50 Hz, the speed at which a motor would run is 3000 revolutions per minute

Speed (in revolutions per minute) = (120 x Frequency) / Number of poles
In this case, the frequency is 50 Hz. However, the number of poles is not given in the question. The number of poles refers to the number of magnetic poles on the rotor of the motor. It can vary depending on the motor's design.

If the number of poles is given, you can substitute it into the formula to find the speed of the motor in revolutions per minute. For example, if the motor has two poles, the formula would be:
Speed = (120 x 50) / 2 = 3000 revolutions per minute

However, since the number of poles is not provided in the question, it is not possible to determine the exact speed of the motor. The speed would depend on the specific motor design and the number of poles it has.

Tension and compression forces act on diagonal and vertical members respectively in a truss structure.

A truss is a construction that comprises of a progression of interconnected triangles, intended to disperse stacks and give security. The powers that follow up on a bracket can be characterized into two kinds: pressure and pressure powers.

Tension powers are powers that draw on a part, like a rope or link. In a support, strain powers follow up on the corner to corner individuals that structure the triangles. These individuals are under pressure since they are being pulled separated.

Compression forces are forces that push on a part, like a segment or shaft. In a support, pressure powers follow up on the upward individuals that associate the top and base harmonies of the bracket. These individuals are under pressure since they are being crushed together.

Notwithstanding pressure and pressure powers, brackets can likewise be exposed to twisting minutes and shear powers, which are brought about by outer burdens following up on the support.

The expression for the energy stored (E) in a stretched wire of original length (L), cross-sectional area (A), tension (T), and Young's modulus (Y) is given by E = Y * e * ln(L) * A

The work done to stretch the wire can be calculated by integrating the force applied over the displacement. In this case, the force applied is the tension (T) in the wire, and the displacement is the change in length (ΔL) from the original length (L) to the stretched length (L + ΔL).

The tension in the wire is given by Hooke's law, which states that the tension is proportional to the extension of the wire:

T = Y * (ΔL / L)

where Y is the Young's modulus of the material of the wire.

Now, let's calculate the work done to stretch the wire:

dW = T * dL

Integrating this expression from L to L + ΔL:

W = ∫ T * dL = ∫ Y * (ΔL / L) * dL

W = Y * ΔL * ∫ (dL / L)

W = Y * ΔL * ln(L) + C

Here, C is the constant of integration. Since the energy stored in the wire is zero when it is unstretched (ΔL = 0), we can set C = 0.

Finally, the expression for the energy stored in the wire (E) is:

E = W = Y * ΔL * ln(L)

or, if we substitute the cross-sectional area (A) and strain (e) of the wire, where e = ΔL / L:

E = Y * e * ln(L) * A

Thus, the expression for the energy stored (E) in a stretched wire of original length (L), cross-sectional area (A), tension (T), and Young's modulus (Y) is given by:

The airplanes have the same effective cross sectional area and drag coefficient. Then, the ratio of drag force at the two densities is 2.3.

The drag force is an air resistance which resist the motion of objects passing through air. It is related to the density ρ, drag coefficient C, velocity v and area A as follows:

D = 1/2 ρCAv².

Here, C and A are the same then the ratio of the drag forces D1 and D2 at the two densities is:

Explanation:

Given that,

The mass of the package = 36 kg

It is raised through a vertical height of 2.4 m.

Initial potential energy of the package will be 0 as it was at ground.

The change in gravitational potential energy is given by :

\(\Delta E=mgh\\\\=36\times 9.8\times 2.4\\\\=846.72\ J\)

Hence, the change in gravitational potential energy is 846.72  J.

The mass : 0.125 lb⋅\(s^2\)/ft.

The damping coefficient : 3 lb⋅s/ft.

The spring constant : 2 lb/ft.

The initial conditions are given as x(0) = 20 in = 20/12 ft and dx/dt(0) = 4 ft/s.

(a) Finding the mass:

The mass can be calculated using the equation m = weight / g, where weight is given as 4 lb and g is the gravitational acceleration of 32 ft/\(s^2\). Therefore, m = 4 lb / (32 ft/\(s^2\)) = 0.125 lb⋅\(s^2\)/ft.

(b) Finding the damping coefficient:

The damping coefficient, denoted by c, can be calculated using the relationship between the viscous resistance and the damping coefficient. In this case, the damping coefficient c = viscous resistance / velocity. Given that the viscous resistance is 3 lb and the velocity is 4 ft/s, we have c = 3 lb⋅s/ft.

(c) Finding the spring constant:

The spring constant, denoted by k, can be calculated using Hooke's Law: k = force / displacement. The force exerted by the spring is equal to the weight of the mass, which is 4 lb. The displacement is given as 24 in = 2 ft. Therefore, k = 4 lb / 2 ft = 2 lb/ft.

(d) Setting up the differential equation:

The differential equation that describes the system can be set up using Newton's second law: m(\(d^{2x}\)/\(dt^2\)) + c(dx/dt) + kx = 0. Substituting the known values, we have (0.125 lb⋅\(s^2\)/ft)(\(d^{2x}\)/\(dt^2\)) + (3 lb⋅s/ft)(dx/dt) + (2 lb/ft)x = 0.

The density (ρh) of hot air inside the balloon, assuming it is uniform throughout, can be expressed in terms of Th, Tc  and ρc (density of surrounding air) using the ideal gas law as follows: ρh = (ρc * Tc) / Th

The ideal gas law states that for a given amount of gas, the product of its pressure (P) and volume (V) is proportional to the product of its temperature (T) and the number of moles (n). Mathematically, it can be expressed as:

PV = nRT

Where R is the ideal gas constant.

Since we are considering a balloon filled with hot air, the pressure and volume inside the balloon remain constant. Therefore, we can modify the ideal gas law to relate the densities of hot air (ρh) and surrounding air (ρc) to their respective temperatures:

(ρh * V) / Th = (ρc * V) / Tc

Here, V represents the volume of the balloon, which cancels out on both sides of the equation.

Simplifying the equation:

ρh / Th = ρc / Tc

Rearranging the equation to solve for ρh:

ρh = (ρc * Tc) / Th

The density (ρh) of hot air inside the balloon, assuming it is uniform throughout, can be calculated using the ideal gas law. The expression for ρh in terms of Th (temperature of hot air), Tc (temperature of surrounding air), and ρc (density of surrounding air) is given as: ρh = (ρc * Tc) / Th.

We can use the equations of motion under constant acceleration to calculate how far the stone lands from the cliff's base. Since the stone is being thrown horizontally in this instance, the initial vertical velocity is zero, and gravity is the only acceleration acting on the stone.

Given:

Initial vertical velocity (v) = 0 ft/s (thrown horizontally)

Height (h) = 100 ft

Initial velocity (v) = 20 ft/s

The following equation can be used to determine how long it will take the stone to fall from the top of the cliff to the ground:

h = (1/2) × g × t²

Where g is the acceleration due to gravity (approximately 32 ft/s^2) and t is the time.
