The substrate Glycogen is utilized in two primary energy systems: the Glycolytic System (also known as the Anaerobic Lactic System) and the Oxidative System (also known as the Aerobic System).

1. Glycolytic System: This energy system rapidly breaks down glycogen into glucose, which then undergoes glycolysis to produce ATP (adenosine triphosphate). This system is anaerobic, meaning it does not require oxygen and is suitable for short, high-intensity activities lasting up to 2 minutes.

2. Oxidative System: In this energy system, glycogen is first broken down into glucose, which then undergoes glycolysis, the citric acid cycle, and oxidative phosphorylation to produce ATP. This system is aerobic, meaning it requires oxygen and is suitable for longer, lower-intensity activities lasting more than 2 minutes.

The substrate glycogen is utilized in both the Glycolytic (Anaerobic Lactic) and Oxidative (Aerobic) energy systems to produce ATP for various physical activities.

If the plates of a spherical capacitor have radii 38.0 mm and 40.0 mm then the capacitance is 1.03 × 10^-11 F and the plate area of a parallel-plate capacitor 20 mm square.

A capacitor is an electronic component that stores electrical energy in an electric field. It consists of two conductive plates separated by an insulating material, which is called a dielectric. The conductive plates are usually made of metal and the dielectric can be made of various materials such as paper, ceramic, plastic, or air.

To calculate the capacitance of a spherical capacitor with radii of 38.0 mm and 40.0 mm, we can use the formula:

C = 4πε₀ / (1/R₁ - 1/R₂)

where C is the capacitance, ε₀ is the permittivity of free space (8.85 × 10^-12 F/m), R₁ is the radius of the inner sphere (in meters), and R₂ is the radius of the outer sphere (in meters).

Converting the radii to meters, we have R₁ = 0.038 m and R₂ = 0.04 m. Plugging in these values, we get:

C = 4πε₀ / (1/0.038 - 1/0.04)

= 1.03 × 10^-11 F

Explanation:

The required amount of heat energy lost in a system when surroundings performed certain amount of work and when internal energy is increased is  calculated to be - 30 kJ.

Given that,

Work done on the system w = 75 kJ

Internal energy ΔU is increased by 45 kJ

Heat energy q lost or gained by the system = ?

From the first law of thermodynamics, mathematically, expression can be written as, ΔU = q + w

q = ΔU - w = 45 kJ - 75 kJ = - 30 kJ

The negative sign indicates that the heat energy is lost.

When the mass is altered, the pendulum's time period is also changed.

In this case, if we were to compare bobs made of steel, wood, and foam of the same size, the motion (the time period T and the amplitude of oscillation) would be affected as follows:

The time period of a pendulum, as well as the amplitude of oscillation, would be affected if you compared bobs made of steel, wood, and foam of the same size. Because of their different masses, the steel bob, the wooden bob, and the foam bob would have different time periods T of oscillation when suspended from the same length of the string.

The bob with the greatest mass, for example, would have the longest period of oscillation, while the bob with the smallest mass would have the shortest period of oscillation.

The formula you provided is already the correct expression for the period of a pendulum:

T = 2π√(L/g)

Where:

T = time period of oscillation

L = length of the pendulum

g = acceleration due to gravity

When we keep the length constant, we can observe that the time period of a pendulum is directly proportional to the square root of its length. That implies that the length of the pendulum has an impact on the pendulum's time period of oscillation.

Therefore, when the mass is altered, the pendulum's time period is also changed.

An outcrop is an uncovered area of rock or other geological material that is exposed at the surface of the Earth. This could be used to determine whether the sediments were deposited close to the shore or in deep water, as well as whether the sediment size was fine or coarse.There are a few factors to consider when interpreting an outcrop in order to determine whether the sediments were deposited close to shore or in deep water.

One factor to consider is the type of rock that is exposed. Coarse-grained rocks, such as sandstones and conglomerates, are more likely to have been deposited near the shore than fine-grained rocks like shales and mudstones, which tend to be deposited in deeper water.Another factor to consider is the presence of certain types of fossils or sedimentary structures, which can provide clues as to the environment in which the sediments were deposited. For example, the presence of ripple marks, which are formed by waves or currents, can suggest that the sediments were deposited near the shore.Interpreting the size of the sediments is also important.

Coarse-grained sediments, such as sand and gravel, are more likely to have been deposited close to shore, while fine-grained sediments, such as silt and clay, tend to be deposited farther offshore. In conclusion, based on the outcrop and the nature of the sedimentary structures, it appears that the sediments were deposited in close to shore. The size of the sediment suggests that the sediment size is coarse.

The length of the spring when a 1.75 kg block is hung would be 16.5 cm.

To solve this problem, we can use Hooke's law, which states that the force exerted by a spring is proportional to the spring's deformation.

First, we can calculate the spring constant (k) using the formula:

k = (F / x)

Where F is the force exerted by the block and x is the deformation of the spring (the difference in length between the compressed and unloaded states).

In the first case, the 2 kg block causes a deformation of 3 cm in the spring (18 cm - 15 cm). We can calculate k by dividing the weight of the block (2 kg) by the deformation (3 cm).

With the value of k known, we can calculate the length of the spring when the 1.75 kg block is hung. We use the same formula:

x = (F / k)

This time, the force exerted by the 1.75 kg block is calculated as the product of its mass (1.75 kg) and gravity (9.8 m/s²).

By substituting the values into the formula, we find that the length of the spring would be 16.5 cm when the 1.75 kg block is hung.

The time period and frequency associated with this motion can be calculated using the formula T=2π/ω and f=1/T, where T is the time period, ω is the angular velocity, and f is the frequency.

In this case, the angular velocity is given as w = */2 rad/s.

Therefore, substituting the value of ω in the formula for T and f, we get T = 4π/* seconds and f = */4 Hz.
The time period represents the time taken by the object to complete one full rotation around its axis, whereas the frequency represents the number of rotations per unit time.

In this case, the time period is inversely proportional to the angular velocity, which means that if the angular velocity increases, the time period decreases, and vice versa. The frequency is directly proportional to the angular velocity, which means that if the angular velocity increases, the frequency also increases, and vice versa.
The time period and frequency associated with the given motion can be calculated using the formula T=2π/ω and f=1/T, where T is the time period, ω is the angular velocity, and f is the frequency.

Answer: 7.47 milliamperes (mA).

Explanation:The drift velocity of electrons in a wire is related to the current flowing through the wire by the equation:

I = nAevd

where I is the current, n is the number density of electrons, A is the cross-sectional area of the wire, e is the charge of an electron, and vd is the drift velocity.

The number density of electrons in copper is approximately 8.5 x 10^28 electrons per cubic meter.

The cross-sectional area of the wire is given by the formula for the area of a circle:

A = πr^2

where r is the radius of the wire. The diameter of the wire is given as 1.628 mm, so the radius is half of this value:

r = 0.814 mm = 0.814 x 10^-3 m

Therefore, the cross-sectional area of the wire is:

A = π(0.814 x 10^-3 m)^2 = 5.21 x 10^-7 m^2

The charge of an electron is -1.6 x 10^-19 C.

The drift velocity is given as 1.00 mm/s = 1.00 x 10^-3 m/s.

Substituting these values into the equation for the current, we get:

I = (8.5 x 10^28 electrons/m^3) x (5.21 x 10^-7 m^2) x (-1.6 x 10^-19 C) x (1.00 x 10^-3 m/s)

I = -7.47 x 10^-3 A

The magnitude of the current is:

|I| = 7.47 x 10^-3 A

Therefore, the magnitude of the current flowing through the wire is 7.47 milliamperes (mA).
