Explanation:

Hi there!

We can begin by solving for the pendulum's velocity at the bottom of its trajectory using the work-energy theorem.

Recall:
\(E_i = E_f\)

Initially, we just have Potential Energy. At the bottom, there is just Kinetic Energy.

\(PE = KE\\\\\)

Working equation:
\(\large\boxed{mgh = \frac{1}{2}mv^2}\)

Rearrange to solve for velocity:
\(gh = \frac{1}{2}v^2\\\\v = \sqrt{2gh}\\\\v = \sqrt{2(9.8)(1.5)} = 5.42 \frac{m}{s}\)

Now, we can do a summation of forces:
\(\Sigma F = T - W\)

The net force is the centripetal force, so:
\(\frac{mv^2}{r} = T - W\)

Rearrange to solve for tension:
\(T = \frac{mv^2}{r} + W\\\\T = \frac{5(5.42^2)}{4} + 5(9.8) = \boxed{85.75 N}\)

Speed, distance, and position are scalar quantities, while velocity, displacement, average velocity, and acceleration are vector quantities.

Speed refers to how fast an object is moving and is a scalar quantity, with only magnitude, without direction. Distance is a scalar quantity that refers to the amount of space between two points, also having only magnitude.

Position is a scalar quantity that refers to the location of an object in space and also has only magnitude.

Velocity, on the other hand, is a vector quantity, as it has both magnitude and direction. It is the rate of change of an object's position over time.

Displacement is another vector quantity, and it refers to the change in position of an object from its starting point.

Average velocity is a vector quantity that is the average of all velocity changes during a certain time interval.

Acceleration is also a vector quantity and refers to the rate of change of velocity. It measures how quickly the velocity of an object changes, and like velocity, it has both magnitude and direction.

Answer:

1) The boiling point of water reduces by 3.28°C at 1,000 m above sea-level

2) The boiling point of water reduces by 6.56°C at 2,000 m above sea-level

Explanation:

The variation of the boiling point of water with elevation is given as follows

The boiling point reduces by 0.5°C for every 152.4 meter increase in elevation

At sea-level, the boiling point temperature of water = 100°C

1) At 1,000 m elevation, the boiling point temperature, T = 100 - (1,000/152.4) × 0.5 ≈ 96.72 °C

Therefore, the boiling point of water reduces by 100° - 96.72° = 3.28°C at 1,000 m above sea-level

2) At 2,000 m elevation, the boiling point temperature, T = 100 - (2,000/152.4) × 0.5 ≈ 93.44°C

The boiling point of water reduces by 100° - 93.44° = 6.56°C at 2,000 m above sea-level

The time taken if Machine A, Machine B, and Machine C all work at the same time is approximately 1.85 hours or 1 hour 51 minutes.

Given data: Machine A and Machine B can complete a job in 2 hours. Machine A and Machine C can complete the same job in 3 hours. Machine B and Machine C can complete the same job in 4 hours.

Solution: Let the efficiency of Machine A, B and C be a, b and c respectively. The amount of work done by the machine is directly proportional to the time taken. So we can write the following equations:

Equation 1: 2a + 2b = 1 (As Machine A and Machine B can complete a job in 2 hours)

Equation 2: 3a + 3c = 1 (As Machine A and Machine C can complete the same job in 3 hours)

Equation 3: 4b + 4c = 1 (As Machine B and Machine C can complete the same job in 4 hours)

Let's solve the above equation: 2a + 2b = 1

=> a + b = 1/2 ------(4)

3a + 3c = 1

=> a + c = 1/3 ------(5)

4b + 4c = 1

=> b + c = 1/4 ------(6)

Adding equations (4), (5), and (6), we get: a + b + a + c + b + c = 1/2 + 1/3 + 1/4

=> 2a + 2b + 2c = (6 + 4 + 3)/12

=> a + b + c = 13/24.

The time taken if Machine A, Machine B, and Machine C all work at the same time will be reciprocal of the efficiency of the three machines when they work together.

=> Efficiency of Machine A, B, and C = a + b + c

= 13/24.

Time taken to complete the job will be reciprocal of the efficiency of the three machines when they work together .i.e Time taken = 1 / (a + b + c)

Time taken = 1 / (13/24)

= 24/13

≈ 1.85 (rounded to 2 decimal places).

Conclusion: Therefore, the time taken if Machine A, Machine B, and Machine C all work at the same time is approximately 1.85 hours or 1 hour 51 minutes.

Answer:

RT = 341.62 Ohms

Explanation:

Given the following data;

R1 = 420 Ohms

R2 = 320 Ohms

R3 = 160 Ohms

To find the equivalent resistance;

From the circuit, we can see that R1 and R2 are connected in parallel;

Mathematically, the total equivalent resistance of resistors connected in parallel is given by the formula;

\( RT = \frac {R1*R2}{R1 + R2} \)

Substituting into the formula, we have;

\( RT1 = \frac {420*320}{420 + 320} \)

\( RT1 = \frac {134400}{740} \)

RT1 = 181.62 Ohms

Next, we resolve the resistors to form a series circuit.

RT = RT1 + R3

RT = 160 + 181.62

RT = 341.62 Ohms

The voltage that the corona wire or corona roller holds is **C. 0VDC**.

The corona wire or corona roller is used in certain electrical devices, such as photocopiers and laser printers, to create a corona discharge. This discharge is necessary for the proper functioning of these devices. However, the voltage applied to the corona wire or roller is typically around 0 volts.

The purpose of the corona wire or roller is to create a localized ionization of the air around it, which assists in the transfer of toner particles onto the paper or drum. This ionization process is achieved by applying a high voltage, usually in the range of a few kilovolts, to the wire or roller.

However, the voltage applied to the corona wire or roller itself is typically referenced to ground potential. Therefore, the wire or roller itself is held at or around 0 volts DC (Direct Current). This helps to maintain a stable and controlled corona discharge for the efficient operation of the device.

A mountain or katabatic breeze is created when cold, dense air flows downhill under the influence of gravity. At night, the ground cools more quickly than the surrounding air, causing the air in contact with the ground to cool and become more dense. The cold, dense air then flows down the slope of a mountain or hillside, forming a mountain breeze.

During the day, the sun warms the ground, causing the air near the ground to heat up and rise. This creates an area of low pressure at the surface, which draws in air from the surrounding higher-pressure areas. As the air from higher elevations flows down toward the lower-pressure area, it creates a katabatic breeze.

A dipole in an external electric field will align itself so that the opposite charges of the dipole face the electric field's direction.

This stable orientation occurs because the electric field exerts a torque on the dipole, causing it to rotate until it is aligned with the field. The stable orientation(s) for a dipole in an external electric field are either parallel or antiparallel to the field direction.

If the dipole is slightly perturbed from these orientations, it will experience a restoring torque that will tend to bring it back to its stable position.

This occurs because the dipole moment experiences a torque that is proportional to its angular displacement from its stable position. The magnitude of the restoring torque is proportional to the dipole moment and the strength of the electric field.

Therefore, any small deviation from the stable orientation will result in a torque that acts to restore the dipole to its stable orientation.

RS is a composition of rotation and reflection in the Euclidean plane E². The precise description of RS depends on the specific properties of the rotation R and reflection S.

In general, if R and S have the same axis or line of symmetry, the composition RS results in a translation. If R and S have intersecting lines of symmetry, RS yields a glide reflection. If R and S have perpendicular lines of symmetry, RS produces a rotation.

It is important to consider special cases, such as parallel lines of symmetry, coinciding axes, or perpendicular lines of reflection, as they may lead to different outcomes. The classification of isometries in E² involves understanding how rotations and reflections combine to create different transformations in the plane.

\( \boxed{\sf Distance \ travelled = 62.5 \ m} \)

Given:

Initial velocity (u) = 25 m/s

Final velocity (v) = 0 m/s (Rest)

Time taken (t) = 5 seconds

To Find:

Distance travelled by car (s)

Explanation:

From equation of motion of object moving with uniform acceleration in straight line we have:

\( \boxed{ \bold{s = (\frac{v + u}{2} )t}}\)

By substituting value of v, u & t in the equation we get:

\( \sf \implies s = ( \frac{0 + 25}{2} ) \times 5 \\ \\ \sf \implies s = \frac{25}{2} \times 5 \\ \\ \sf \implies s = 12.5 \times 5 \\ \\ \sf \implies s = 62.5 \: m\)

\( \therefore\)

Distance travelled by car (s) = 62.5 m

The distance  car travel during that time is 62.5 meter.

Acceleration is the rate at which speed and direction of velocity vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates.

Even if the speed is constant, motion on a circle accelerates because the direction is always shifting. Both effects contribute to the acceleration for all other motions.

Initial velocity (u) = 25 m/s

As the car becomes rest, final velocity (v) = 0 m/s (Rest)

Time taken (t) = 5 seconds.

The deceleration of the car: a = (initial speed - final speed)/time interval

= ( 25 m/s - 0 m/s)/5 second

= 5 m/s²

The distance  car travel during that time = ut - at²/2

= 25 × 5.0 meter - (5×5²/2) meter

= 62.5 meter.

Hence, the distance  car travel during that time is  62.5 meter.

Distance from the central maximum on the screen will a dark fringe from one pattern first coincide with a dark fringe from the other is -0.26 mm

Since the slit separation is 2.0 mm , and two wavelengths, 900 nm and 700 nm , illuminate the slits. A screen is placed 2.6 m from the slits

λ\(1\) = 900 nm

λ\(2\) = 700 nm

D = 2.6 m

d = 2 mm

The distance is calculated using formula ,

\(Y\)= λD/d

Hence,

\(Y1\) = λ\(1\) D/d

\(Y2\) = λ\(2\) D/d

\(Y1\) = 900 × \(10^{-9}\) × 2.6 / 2 × \(10^{-3}\)

Therefore, \(Y1\) = 1.170 mm

\(Y2\) = 700 × \(10^{-9}\) × 2.6 / 2 × \(10^{-3}\)

Therefore, \(Y2\) = 0.910 mm

So the spacing between these two bright stripes is:  \(Y2\) -\(Y1\)  = -0.26 mm

The period of a physical pendulum depends on its mass distribution and can be calculated using the moment of inertia. The equation for the period takes into account the mass, length, radius, and distance between the pivot and center of mass.

A physical pendulum is a type of pendulum in which the mass is distributed along the length of the pendulum, and its period depends on the distribution of the mass.

To find the period of the physical pendulum, we need to consider the moment of inertia of the system, which is given by the sum of the moment of inertia of the rod and the moment of inertia of the sphere about the pivot.

Assuming that the length of the rod is much greater than the radius of the sphere, we can approximate the moment of inertia of the rod as \((1/3)ml^2\), where m is the mass of the rod and l is its length. The moment of inertia of the sphere about the pivot is \((2/5)mR^2\), where R is the radius of the sphere.

Using the parallel axis theorem, we can find the moment of inertia of the system about the pivot as \((1/3)ml^2 + (2/5)mR^2 + md^2\), where d is the distance between the pivot and the center of mass of the system.

The period of the physical pendulum is given by \(T = 2\pi \sqrt{(I/mgd)}\), where g is the acceleration due to gravity.

Thus, the period of the physical pendulum depends on the distribution of the mass, and it cannot be determined without knowing the values of m, l, R, and d.
