Explanation:

The work done by the boy is due to the change in the position of the cement vertically. Hence, the work done in this case will be equal to the potential energy of the cement:

\(W = P.E\\W = mgh\)

where,

W = Work done = ?

mg = W = weight of cement = 500 N

h = height covered = 2.5 m

Therefore,

\(W = (500\ N)(2.5\ m)\)

W = 1250 J = 1.25 KJ

True, the ratio of turns on each side of the transformer controls the ratio of voltage from input to output.

A transformer consists of two coils, called the primary and secondary coils, which are wound around a magnetic core. The number of turns in each coil is directly related to the voltage ratio.

In a step-up transformer, the secondary coil has more turns than the primary coil, resulting in a higher output voltage.

Conversely, in a step-down transformer, the primary coil has more turns than the secondary coil, resulting in a lower output voltage. The ratio of turns in the primary coil (N1) to the turns in the secondary coil (N2) determines the voltage ratio (V1/V2), as given by the formula:

V1/V2 = N1/N2

By adjusting the number of turns in each coil, the desired voltage ratio can be achieved, allowing the transformer to either step up or step down the input voltage to meet the requirements of the connected electrical devices.

Explanation:

Answer:

yes

Explanation:

because motion is relevant

Answer:

Motion is mathematically defined as displacement, distance, velocity, acceleration, speed, and time. The motion of a body is recognized by adding a frame of reference to an observer and measuring the change in position of the body related to that frame with the change in time.

Answer:

14.4m

Explanation:

u = 0 i.e it started from rest

acceleration (a) = 3.2m/s2

time taken (t) = 3.0s

Using the second equation of motion:

s = ut + 1/2at2

s = 0(3.0) + 1/2(3.2)(3.0)2

s = 1.6(9.0)

s = 14.4m

hence the distance covered within that time is 14.4m.

By the definition of wavelength, the answer is the letter D, the wavelength would decrease.

We can see in the diagram a wave motion.

Explanation:

In the inelastic collision of the carts, the two carts fuse into an object with double the mass of the original cart. The works due to friction and the frictional force exerted to stop the two carts over 20 meters is 980 Joules.

Generally, To calculate the work due to friction and the frictional force exerted to stop the two carts over 20 meters, we will need to know the coefficient of friction between the carts and the track, the mass of the two carts, and the acceleration due to gravity.

The equation for work due to friction is:

Work = Friction force * Distance

The equation for the friction force is:

Friction force = Coefficient of friction * Normal force

The normal force is equal to the mass of the two carts multiplied by the acceleration due to gravity:

Normal force = Mass * Gravity

We can substitute these equations into the equation for work to get:

Work = (Coefficient of friction * Mass * Gravity) * Distance

To calculate the work, we need to substitute in the values for the coefficient of friction, mass, gravity, and distance. Let's say the coefficient of friction is 0.5, the mass of the two carts is 10 kilograms, and the acceleration due to gravity is 9.8 meters per second squared. The distance the carts travel is 20 meters.

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

Work = (0.5 * 10 * 9.8) * 20

Solving this equation gives us a final value for the work of: 980 Joules.

The negative sign indicates that the voltage of the point charge decreases as it moves in the direction of the electric field is - 240 V.

ΔV = - Ed

ΔV = - (8,000 N/C)(0.03 m) = - 240 V

Voltage, also known as electric potential difference, is a measure of the electric potential energy per unit of charge in an electrical circuit. It represents the force that drives the flow of electric charge from one point to another in a circuit.

In practical terms, voltage can be thought of as the pressure that pushes electric charge through a circuit. Just as water flows from a higher pressure area to a lower pressure area, electric charge flows from a higher voltage point to a lower voltage point. This flow of charge is what creates the electrical current that powers our devices and appliances. Voltage is measured in volts, which is the unit of electric potential. It can be measured using a voltmeter, which is a device that is connected in parallel to the circuit to measure the voltage across a specific component.

We have demonstrated that (pω)ω∈Ω is the point mass function of some distribution, and that the random variable X has a point mass function PX equal to (pω)ω∈Ω.

In order to show that (pω)ω∈Ω is the point mass function of some distribution, we need to demonstrate that it satisfies the properties of a probability distribution.

a) Let's consider the properties of a probability distribution. Firstly, the values of pω must be non-negative for all ω ∈ Ω. This is true since pω is defined as the product of two non-negative values hω1 and hω2.

Secondly, the sum of probabilities over all possible outcomes must be equal to 1. In this case, we need to show that the sum of (pω)ω∈Ω over all possible ω in Ω is equal to 1. To do this, we can consider the sum:

Σ(pω)ω∈Ω = Σ(hω1 hω2)ω∈Ω

By the properties of the point mass function h, we know that Σhω1 = 1 and Σhω2 = 1. Therefore, the above expression becomes:

Σ(pω)ω∈Ω = Σ(hω1 hω2)ω∈Ω = 1 * 1 = 1

Thus, we have shown that (pω)ω∈Ω satisfies the properties of a probability distribution.

b) Now let's consider the random variable X(ω) = ω1 + ω2 and show that its point mass function PX is equal to (pω)ω∈Ω.

To calculate PX(x) = P({ω ∈ Ω : X(ω) = x}), we need to consider the event where the sum of the components ω1 and ω2 is equal to x. This can be expressed as:

{ω ∈ Ω : X(ω) = x} = {(ω1, ω2) ∈ Ω : ω1 + ω2 = x}

Now, notice that this event is equivalent to the event {ω1 = n, ω2 = x - n} for any fixed n. The probability of this event is given by pω1 pω2 = hω1 hω2, which matches the point mass function (pω)ω∈Ω.

By considering all possible values of n, we can cover all the cases for X(ω) = x, and therefore, we have shown that PX(x) is equal to (pω)ω∈Ω.

The required time taken by the boxster to reach scion is calculated to be 58.45 s.

Let scion is car A and boxster is car B.

The vehicle A travelled a distance of,

x = VA × t ----(1)

where,

VA is the speed of the car

t is the time

The distance travelled by car B before reaching car A is,

x + x₀ = VB × t ----(2)

Using (1) in (2), we have,

x + x₀ = VB × t

VA × t + x₀ = VB × t

x₀ = (VB - VA)t

Making t as subject, we have,

t = x₀/(VB - VA) = 339/(24.4-18.6) = 339/5.8 = 58.45 s
