 It would take the runner approximately 10,268.29 seconds (or about 2 hours, 51 minutes, and 8 seconds) to complete a marathon race of 42.2 km, maintaining an average speed of 4.1 m/s.

We can use the formula:

time = distance ÷ speed

to calculate the time it would take the runner to complete a marathon race of 42.2 km, given an average speed of 4.1 m/s.

First, we need to convert the distance to meters, as the speed is given in meters per second:

42.2 km = 42,200 m

Now, we can substitute the values into the formula:

time = distance ÷ speed

time = 42,200 m ÷ 4.1 m/s

time ≈ 10,268.29 s

Thus the time that the runner would take is  10,268.29 seconds  to complete a marathon race.

Since the electric field between the plates is constant, If the two plates are brought closer together, the potential difference between the two plates decreases

The relation between potential difference and the electric field is given by

ΔV = E.d

Since the electric field is maintained constant, the potential difference is directly inversely proportional to the distance between the plates.

The potential difference between the plates will therefore likewise decrease if the distance between the plates is reduced, we will state in this case.

The energy required to move a unit charge, or one coulomb, from one point to the other in a circuit is measured as the potential difference between the two points. Potential difference is measured in volts or joules per coulomb.

The estimated Vmax is always higher than the highest measured velocity, as the estimated Vmax represents the theoretical maximum velocity that the enzyme can achieve.

In enzyme kinetics, Vmax refers to the maximum velocity or rate of an enzyme-catalyzed reaction. It represents the theoretical maximum rate at which the enzyme can convert substrate into product when the enzyme is fully saturated with substrate.

When measuring the velocity of an enzyme-catalyzed reaction, it is possible that the reaction does not reach the maximum velocity due to various factors such as limitations in substrate concentration or other experimental conditions. Therefore, the measured velocity will always be lower than the theoretical maximum velocity or Vmax.

In other words, Vmax represents an asymptotic value that can never be exceeded in practice. It is the maximum velocity that the enzyme can reach under ideal conditions, where the enzyme is fully saturated with substrate. Therefore, it makes sense that the estimated Vmax is always higher than the highest measured velocity, as the estimated Vmax represents the theoretical maximum velocity that the enzyme can achieve.

Liquid water at temperatures below freezing is termed "supercooled water."

Supercooled water refers to liquid water that exists in a liquid state below its freezing point of 0 degrees Celsius (32 degrees Fahrenheit) without undergoing solidification. This phenomenon occurs when water is in a pure and exceptionally pure state, free from impurities and nucleation sites that can initiate the formation of ice crystals.

Under normal conditions, water freezes into ice when its temperature reaches or falls below 0 degrees Celsius. However, if the water is pure and lacks nucleation sites, such as dust particles or imperfections on container surfaces, it can remain in a liquid state even at temperatures below freezing.

Hence, Liquid water at temperatures below freezing is termed supercooled water.

Explanation:

Rolling friction takes place when an object rolls on the surface. Sliding friction takes place when two surfaces are rubbed against each other. Rolling friction is much less than sliding friction for same pair of bodies. When one body rolls upon another, there is theoretically no sliding or slip between them.

The object which completely absorbed the white light can be a Black Body.

An object that completely absorbs all of the light that strikes it, with none transmitted or reflected, is referred to as a black body.

A black body is a theoretical concept in physics, and is characterized by its ability to absorb all wavelengths of electromagnetic radiation that fall upon it.

In reality, there are no perfect black bodies, but materials that are dark and have a high absorption coefficient, such as carbon black, can approach this ideal.

Black bodies play an important role in thermal radiation and the study of thermodynamics, as their absorption and emission of electromagnetic radiation is well understood and can be used to study other physical systems.

Explanation:

From the calculation, we can conclude that both race car A and B have the same magnitude of velocity but accelerate at different magnitude

VELOCITY AND ACCELERATION

The rate of change of displacement is called Velocity. While acceleration is the rate of change of velocity.

Given that  a race Car A accelerates on a straight track from 0 to 100 kilometers/second in 6 seconds.

Since acceleration = \(\frac{Change in velocity}{time taken} \)

a = 1000(100 - 0)/6

a = 100000/6

a = 16666.67 m/\(s^{2} \)

And race Car B accelerates on a straight track from 0 to 100 kilometers/second in 5 seconds.

acceleration =  \(\frac{Change in velocity}{time taken} \)

a = 1000(100 - 0)/5

a = 100000/5

a = 20000 m/\(s^{2} \)

From the calculation above, we can conclude that both race car A and B have the same magnitude of velocity but accelerate at different magnitude.

Race car A accelerates at 16666.67 m/\(s^{2} \), while race car B accelerates at 20000 m/\(s^{2} \)

so after solving we get as,

W = 0.686 Joules

The potential difference across all three resistors in a series circuit is the same, as the voltage from the battery is divided across the resistors in proportion to their resistance values. Therefore, option B (potential difference ΔV) is the same for all three resistors.

The resistance of each resistor is different, so option C is not the same for all three resistors.

The current through each resistor is the same, as there is only one path for the current to flow in a series circuit. Therefore, option A (current I) is the same for all three resistors.

TRUE. When air masses of different densities collide, the less dense air mass is forced to rise through frontal lifting.

In meteorology, a front is a transition area between two air masses of different densities. The atmosphere's temperature, moisture content, and wind direction are all influenced by these air masses. The types of fronts are warm, cold, stationary, and occluded fronts. The front types are determined by the characteristics of the air masses and the direction of their movement. The types of the front are Warm front: When a warm air mass replaces a cold air mass, it is called a warm front. Warm fronts typically move more slowly than cold fronts. Cold front: A cold front happens when a cold air mass replaces a warm air mass. They have steeper pressure gradients than warm fronts, and they travel faster. Rain, thunderstorms, and cold temperatures are all common with this type of front. Stationary front: This occurs when two air masses meet and neither advances. There is a lot of rain along the stationary front. Occluded front: This is a type of front that develops when a cold front overtakes a warm front. When the cool air catches up to the warm air, an occluded front forms. The fronts can cause precipitation to fall.

The static coefficient of friction between the box and the tabletop is 220/mg.

The maximum static frictional force that the tabletop can exert on the box is given by:

where \(\mu_s\) is the static coefficient of friction between the box and the tabletop, and F_normal is the

Assume the mass of the box is m kg.

normal force exerted by the tabletop on the box, which is equal to the weight of the box, i.e., \(F_{normal} = m \times g\), where g is the acceleration due to gravity.

When you push the box with a force of 220 N, the box just begins to move, which means that the static frictional force is equal to the applied force:

\(F_{f_{max}} = 220 \ N\)

Therefore, the static coefficient of friction is:

\(\mu_s = F_{f_{max}} / F_{normal}\)

Substituting the expression for \(F_{normal}\) and solving for \(\mu_s\), we get:

\(\mu_s = (220 \ N) / (m \times g)\)

Answer:

(1) - v(t) = 9.18t - 1.12

(2) - a(t) = 9.18 m/s²

Explanation:

We are given the position function, y(t) = 4.59t² - 1.12t + 0.03. We are asked to determine the following:

\(\hrulefill\)

To find the velocity function simply take the derivative of the position function.

y'(t) = v(t) = 9.18t - 1.12

Using the graph we can find the object's initial velocity by pugging in t=0.220 s.

=>  v(0.220) = 9.18(0.220) - 1.12

=>  v(0.220) = 0.8996 m/s \(\hrulefill\)

To find the acceleration function either take two derivatives of the position function or one of the velocity function.

y''(t) = v'(t) = a(t) = 9.18 m/s²

Thus, the object is speeding up with constant acceleration.

A 600-w TV receiver is turned on for 4 hours with nobody watching it. If electricity costs 10 cents/kWh, the amount of money wasted is cents. Therefore, the amount of money wasted in this case is 24 cents.

There are different steps to calculate the money wasted in this case. Here is the step-by-step solution to this problem:

First, we need to calculate the energy consumed in kWh:

Energy consumed = Power × Time Power = 600 W Time = 4 hours

Energy consumed = Power × Time Energy consumed = 600 W × 4 hours

Energy consumed = 2400 Wh.

To convert Wh into kWh, we need to divide the energy consumed by 1000:

Energy consumed = 2400 Wh = 2.4 kWh.

Now, we can calculate the amount of money wasted:

Cost of 1 kWh = 10 cents Cost of 2.4 kWh = 2.4 kWh × 10 cents/kWh

Cost of 2.4 kWh = 24 cents.  

A 600-w TV receiver is turned on for 4 hours with nobody watching it. If electricity costs 10 cents/kWh, the amount of money wasted is cents. The energy consumed by the TV receiver can be calculated by multiplying the power rating by the time it is used. In this case, the power rating is 600 W, and the time is 4 hours.

Therefore, the energy consumed is 600 W × 4 hours = 2400 Wh.

To convert the energy consumed into kWh, we need to divide it by 1000. So, 2400 Wh = 2.4 kWh. The cost of electricity is 10 cents per kWh.

Therefore, the cost of 2.4 kWh is 2.4 kWh × 10 cents/kWh = 24 cents.

This is the amount of money wasted by keeping the TV receiver turned on for 4 hours without anyone watching it. It is important to turn off electrical appliances when they are not in use to save electricity and reduce the electricity bill.

θi = angle of incidence = ?

θr = angle of refraction = 25°

Therefore,

\(1.75 = \frac{Sin\ \theta_i}{Sin\ 25^o} \\\\(1.75)(Sin\ \ 25^o) = Sin\ \theta_i\\\\\theta_i = Sin^{-1}(0.739)\)

To study vectors it is best to select a coordinate system and manipulate it in that coordinate system and the component of A in x is 0.9396 while in y it is 0.342.

An item with both magnitude and direction is referred to be a vector.

A vector can be visualized geometrically as a straight spline, with a pointing in the orientation and a length equal to the value of the vector.

A vector has magnitude and direction so we can form a vector coordinate system and manipulate each vector in that such that it will be clear to study all vectors.

Given the vector A,

Magnitude |A| = 1 units

The angle of inclination from the x-axis is 20°.

Component of A in the x-axis ⇒

|A|cos20° = 1(0.9396) = 0.9396

Component of A in the y-axis ⇒

|A|sin20° =1(0.342) = 0.342

Hence "The component of A in x is 0.9396 while in y it is 0.342".
