The angular momentum of a system is constant if the total linear momentum of the system is zero.

The main answer is that if the total linear momentum of a system of particles is zero, the angular momentum of the system remains constant regardless of the choice of origin. Angular momentum is a measure of rotational motion and depends on the distribution of mass and velocity within the system

When the total linear momentum is zero, it implies that the system's center of mass is stationary or moving at a constant velocity. In such cases, the system's angular momentum is independent of the origin chosen for calculations.

Answer:

If both the radius and frequency are doubled, then the tension is increased 8 times.

Explanation:

The radial acceleration (\(a_{r}\)), measured in meters per square second, experimented by the moving end of the string is determined by the following kinematic formula:

\(a_{r} = 4\pi^{2}\cdot f^{2}\cdot R\) (1)

Where:

\(f\) - Frequency, measured in hertz.

\(R\) - Radius of rotation, measured in meters.

From Second Newton's Law, the centripetal acceleration is due to the existence of tension (\(T\)), measured in newtons, through the string, then we derive the following model:

\(\Sigma F = T = m\cdot a_{r}\) (2)

Where \(m\) is the mass of the object, measured in kilograms.

By applying (1) in (2), we have the following formula:

\(T = 4\pi^{2}\cdot m\cdot f^{2}\cdot R\) (3)

From where we conclude that tension is directly proportional to the radius and the square of frequency. Then, if radius and frequency are doubled, then the ratio between tensions is:

\(\frac{T_{2}}{T_{1}} = \left(\frac{f_{2}}{f_{1}} \right)^{2}\cdot \left(\frac{R_{2}}{R_{1}} \right)\) (4)

\(\frac{T_{2}}{T_{1}} = 4\cdot 2\)

\(\frac{T_{2}}{T_{1}} = 8\)

If both the radius and frequency are doubled, then the tension is increased 8 times.

If both the radius and frequency are doubled, then the tension will be increased 8 times.

From kinematic formula:

\(\bold {a_r = 4\pi r^2 \times f^2 \times R^2}\) .............................. (1)

Where:  

f - Frequency,    

R - Radius of rotation,  

From Second Newton's Law,

\(\bold {\sum F = T = m\times a_r }\) ......................... (2)

Where

m is the mass of the object,

From equation 1 and 2,

\(\bold {T = m\times 4\pi r^2 \times f^2 \times R^2}\\\) .................... (3)

From equation, tension is directly proportional to the radius and the square of frequency.

Then, if radius and frequency are doubled, then the ratio between tensions is:

\(\bold {\dfrac {T_2}{T_1} = (\dfrac {F_2}{F_1})^2 \times \dfrac {R_2}{R_1} = 4 \times 2 = 8 }\)  

Therefore, If both the radius and frequency are doubled, then the tension will be increased 8 times.

To a stationary observer, a man jogs east at 6 m/s and a woman jogs west at 2 m/s. From the man's frame of reference, the woman's velocity is 4 m/s.

Velocity is a term that defines that how much a particle covered the distance in a particular time. Velocity is a vector quantity. It can be measured in m/s or cm/s.

To calculate the velocity we are using the formula, Δv= v₁-v₂

Here we are given,

v₁= According to a stationary observer, velocity of a man=6 m/s East.

v₂=According to a stationary observer, velocity of a woman= 2 m/s West.

We have to calculate the woman's velocity, from the man's frame of reference=  Δv

1a) The total energy stored when all three weights are raised by 70 cm is 80.5 J.

1b) The height of the tank is 2 m.

2b) The potential energy is converted into kinetic energy when the water flows out of the taps 6.32 m/s.

3a) The mass of water that goes over the falls every second is 1 x 10⁶ kg.

3b) The gravitational potential energy of 1 kg of water at the top of the falls 1000 J.

3c) The speed of the water as it reaches the bottom if all the GPE stored in 1 kg of water is transferred to kinetic energy is 44.72 m/s.

3d) The water will not be falling as fast as the speed calculated in part c suggests because of the presence of air resistance and the fact that the water falls through a medium (air) which offers resistance to its motion.

3e) The energy transferred when the GPE stored in the water falling in one second is transferred to other energy stores is finally stored in thermal energy stores due to the heat generated by the water as it hits the bottom.

1a) To calculate the amount of energy stored in the three weights, we use the formula given below:

E = mgh

Where,E = Energy (Joules)

m = Mass (kg)

g = Gravity (10 N/kg)

h = Height (m)

For the 4.5 kg weight:

E = 4.5 x 10 x 0.7 = 31.5 J

For each of the 3.5 kg weight:

E = 3.5 x 10 x 0.7 = 24.5 J

Thus, the total energy stored when all three weights are raised by 70 cm is:

31.5 J + 24.5 J + 24.5 J = 80.5 J

1b) To calculate how far the 4.5 kg weight must be lifted to store 45 J of energy, we use the formula:

E = mghh = E/mg = 45 / (4.5 x 10) = 1 m2a)

To calculate the gravitational potential energy stored in the water in the tank when it is full, we use the formula given below:

E = mgh

Where,E = Energy (Joules)

m = Mass (kg)

g = Gravity (10 N/kg)

h = Height (m)

The mass of 1 litre of water is 1 kg and the tank can hold 200 litres of water. Therefore, the total mass of water in the tank is:

Mass = 200 kg

The height of the tank is 2 m.

Therefore, the gravitational potential energy stored in the water in the tank is:

E = mgh = 200 x 10 x 2 = 4000 J

Assumptions made in the answer:

We have assumed that the tank is full.

2b) To calculate the speed at which the water would come out of the bathroom and kitchen taps, we use the formula given below:

PE = KEPE = mghKE = 1/2mv²

Where,PE = Potential Energy (Joules)

KE = Kinetic Energy (Joules)

m = Mass (kg)

g = Gravity (10 N/kg)

h = Height (m)

v = Velocity (m/s)

Assuming that the potential energy of the water in the tank is converted into kinetic energy when the water flows out of the taps, the potential energy stored in the water in the tank is given by:

PE = mgh = 200 x 10 x 2 = 4000 J

The potential energy is converted into kinetic energy when the water flows out of the taps.

Therefore, KE = 1/2mv²v² = 2KE/mv² = 2(4000)/200 = 40 m²/s²v = √(40) = 6.32 m/s (speed of the water coming out of the taps)

3a) To calculate the mass of water that goes over the falls every second, we use the formula given below:

Mass = Volume x Density

Where,Volume = 1000 m³/s, Density = 1000 kg/m³, Mass = 1000 x 1000 = 1000000 kg = 1 x 10⁶ kg

3b) To calculate the gravitational potential energy of 1 kg of water at the top of the falls, we use the formula:

E = mgh

Where,m = 1 kg, g = 10 N/kg, h = 100 m, E = 1 x 10 x 100 = 1000 J

3c) To calculate the speed of the water as it reaches the bottom if all the GPE stored in 1 kg of water is transferred to kinetic energy, we use the formula given below:

PE = KEP

E = mgh

KE = 1/2mv²

Where,PE = Potential Energy (Joules)

KE = Kinetic Energy (Joules)

m = Mass (kg)

g = Gravity (10 N/kg)

h = Height (m)

v = Velocity (m/s)

Assuming that all the potential energy is converted into kinetic energy when the water reaches the bottom,

PE = KEKE = mghv² = 2mghv² = 2(1)(10)(100)v² = 2000v = √(2000) = 44.72 m/s

3d) The water will not be falling as fast as the speed calculated in part c suggests because of the presence of air resistance and the fact that the water falls through a medium (air) which offers resistance to its motion.

3e) To calculate the total energy transferred per second as the GPE stored in the water falling in one second is transferred to other energy stores, we use the formula given below:

Power = Energy / Time

Where,Power = 1 x 10⁶ x 10 x 100 = 1 x 10⁹ W = 1 GW (assuming that 1 m³ of water falls every second)3f)

The energy transferred when the GPE stored in the water falling in one second is transferred to other energy stores is finally stored in thermal energy stores due to the heat generated by the water as it hits the bottom.

This question involves the concepts of centripetal force, range of projectile and projectile motion.

The magnitude of centripetal force is "2812.8 N".

First, we will find the velocity of the ball by using the formula of the range of the projectile.

\(R = \frac{v^2Sin2\theta}{g}\)

where,

R = range of projectile = 86.75 m

v = speed = ?

θ = launch angle = 47.9°

g = acceleration due to gravity = 9.81 m/s²

Therefore,

\(86.75\ m = \frac{(v)^2Sin(2)(47.9^o)}{9.81\ m/s^2}\\\\v = \sqrt{\frac{(86.75\ m)(9.81\ m/s^2)}{Sin95.8^o}}\)

v = 29.25 m/s

Now, we will use the formula to find out the centripetal force:

\(F_c = \frac{mv^2}{r}\)

where,

\(F_c\) = Centripetal Force = ?

m = mass of the ball = 7.3 kg

v = speed = 29.25 m/s

r = radius = 2.22 m

The first successful attempt to establish the size of Earth is credited to the ancient Greek mathematician and astronomer Eratosthenes.

Eratosthenes noticed that at noon on the summer solstice, the sun was directly overhead in Syene, a city in southern Egypt, casting no shadow. However, in Alexandria, which was located about 500 miles north of Syene, the sun cast a shadow of approximately 7.2 degrees. Eratosthenes realized that the difference in the shadow length was caused by the curvature of the Earth's surface, and he used his knowledge of geometry to calculate the circumference of the Earth.

Eratosthenes' estimate was remarkably accurate, coming within about 2% of the Earth's actual circumference. His achievement laid the groundwork for future studies of Earth's size and shape and cemented his legacy as one of the greatest scientists of antiquity.

So,the first successful attempt to establish the size of Earth is credited to the ancient Greek mathematician and astronomer Eratosthenes. He was born in Cyrene, a Greek colony in present-day Libya, in 276 BCE and was the chief librarian at the Library of Alexandria in Egypt.

"Microwave transmission systems are used for high volume, long distance, line-of-sight communications."

Microwave is a line-of-sight wireless communication technology that uses high frequency beams of radio waves to provide high speed wireless connections that can send and receive voice, video, and data information.

Due to their small wavelength and ability to be focused into narrow beams that may be targeted directly at the receiving antenna, microwave links are frequently employed for point-to-point communications. As opposed to lower frequency radio waves, which interfere with one other, this enables neighbouring microwave equipment to operate on the same frequencies.

Another benefit is that the microwave band has a very high information-carrying capacity due to its high frequency; its bandwidth is 30 times greater than that of the radio spectrum below it.

While there is no direct relationship between speed and thinking distance, higher speeds can result in longer thinking distances due to the increased reaction time needed by the driver.

The relationship between speed and thinking distance is not a direct one, as thinking distance is primarily influenced by the driver's reaction time rather than the actual speed of the vehicle. Thinking distance refers to the distance traveled by a vehicle during the driver's reaction time after perceiving a hazard.

However, there is an indirect relationship between speed and thinking distance in the sense that higher speeds generally result in longer thinking distances. When a vehicle is traveling at a higher speed, the driver needs more time to process information, make decisions, and react to potential hazards. Therefore, a higher speed can lead to a longer thinking distance.

It is important to note that thinking distance is just one component of the total stopping distance, which also includes braking distance. Braking distance is directly influenced by the speed of the vehicle. Higher speeds require longer braking distances to bring the vehicle to a stop.
