A monorail starts from rest and accelerates at a rate of 2.2m/s2 for 10s.Then it runs at a constant speed for 74s and then slows down at a rate of 1.5m/s2

Answers

Answer:

d = 4217 m

Explanation:

Case 1.

Initial velocity, u = 0

Acceleration, a = 2.2 m/s²

Let d₁ is the distance in case 1. Using second equation of motion as follows :

[tex]d_1=ut+\dfrac{1}{2}a_1t_1^2\\\\\text{Here, u =0}\\\\d_1=\dfrac{1}{2}\times 2.2\times 10^2\\\\d_1=110\ m[/tex]

Let d₂ in the distance in case 2. Using second equation of motion as follows :

[tex]d_2=ut+\dfrac{1}{2}a_2t_2^2\\\\\text{Here, u =0}\\\\d_2=\dfrac{1}{2}\times 1.5\times 74^2\\\\d_2=4107\ m[/tex]

Total distance,

D = d₁ + d₂

D = 110 + 4107

D = 4217 m

Hence, the total distance covered is 4217 m.

Plz help me. I need urgent Why a magnetic compass is used to determine direction? Why a nail gets magnetized when kept close to magnet? Why two pins get attracted by bar magnet maintain distance between ends?

Answers

Answer:

Compasses are mainly used in navigation to find direction on the earth. This works because the Earth itself has a magnetic field which is similar to that of a bar magnet. The compass needle aligns with the Earth's magnetic field direction and points north-south. Also, In a magnet all the domains are oriented in the same direction. In the case of a nail, the domains can be aligned in the same direction causing the nail to become magnetic. That is because if you hang a bar magnet from a thread, the north pole will point to magnetic north. When you bring one north pole close to another north pole they repel each other. You can feel the two magnets pushing each other apart.

Explain why there is a delay between the arrival of the sound transmitted through the steel pipe and the sound transmitted by the air in the pipe.​

Answers

Answer: RATE ME AND MAKE ME BRAININESS AND THANK ME

Explanation:Sound waves are pressure waves that travel through Earth's crust, water bodies, and atmosphere. Natural sound frequencies specify the frequency attributes of sound waves that will efficiently induce vibration in a body (e.g., the tympanic membrane of the ear) or that naturally result from the vibration of that body.

Sound waves can potentiate or cancel in accord with the principle of superposition and whether they are in phase or out of phase with each other. Waves of all forms can undergo constructive or destructive interference. Sound waves also exhibit Doppler shifts—an apparent change in frequency due to relative motion between the source of sound emission and the receiving point. When sound waves move toward an observer the Doppler effect shifts observed frequencies higher. When sound waves move away from an observer the Doppler effect shifted observed frequencies lower. The Doppler effect is commonly and easily observed in the passage of planes, trains, and automobiles.

The speed of propagation of a sound wave is dependent upon the density of the medium of transmission. Weather conditions (e.g., temperature , pressure, humidity , etc.) and certain geophysical and topographical features (e.g., mountains or hills) can obstruct sound transmission. The alteration of sound waves by commonly encountered meteorological conditions is generally negligible except when the sound waves propagate over long distances or emanate from a high frequency source. In the extreme cases, atmospheric conditions can bend or alter sound wave transmission.

The speed of sound in steel is about 17 times as fast as it's speed in air.

Naturally, when a sound starts out at one end of a pipe, it reaches the other end thru the steel before it reaches the other end thru the air in the pipe.

The longer the pipe is, the longer will be the delay between the arrival of the two sounds at the other end.

Determine the vector sum of the displacements Δd1 = 2.4 m [32° S of W]; Δd2 = 1.6 m [S]; and Δd3 = 4.9 m [27° S of E].

Answers

Answer:

3.44 metres

Explanation:

To determine the vector sum of the displacements Δd1 = 2.4 m [32° S of W]; Δd2 = 1.6 m [S]; and Δd3 = 4.9 m [27° S of E], resolve the given parameters into x - component and y - component.

Resolving into x - component

- 2.4cos32 + 4.9cos27 = 2.3306

Resolving into y - component

- 2.4sin32 - 4.9sin27 - 1.6 = - 2.553

The vector sum of the displacement will be

Sqrt( 2.3^2 + 2.6^2) =

Sqrt ( 11.81)

3.44 m

Therefore, the vector sum of the displacements is 3.44 metres

b. 18.5 m/s
c. 171m/s
d. 9.8 m/s
e. 17.5 m/s

Answers

Given :

Height from which rock is dropped, h = 17.5 m.

Initial velocity, u = 0 m/s.

To Find :

Speed does the rock strike the water.

Solution :

We know, by equation of motion :

[tex]v^2-u^2=2as[/tex]      ......( 1 )

Here , a = g = 9.8 m/s² ( Acceleration due to gravity )

Putting all given values in 1 , we get :

[tex]v^2-u^2=2as\\\\v=\sqrt{2gh}\\\\v=\sqrt{2\times 9.8\times 17.5}\ m/s\\\\v=18.5\ m/s[/tex]

Therefore, speed with rock strike the water is 18.5 m/s.

Hence, this is the required solution.

What is the law of conservation of energy?

According to the Law of Conservation of Energy, energy can neither be created nor destroyed, but it can be transferred from one form to another.

The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.

In the above problem, the potential energy gets converted into kinetic energy at the expense of the loss of gravitational potential energy between the two positions.

A 0,34-kg volleyball is flying west at 1,98 m/s when it strikes a stationary 0,60-kg basketball dead centre. The volleyball rebounds east at 0,79 m/s. What will be the velocity of the basketball immediately after impact? Choose the east direction as positive.

Answers

Explanation:

use the law of conservation of momentum

M1U1+M2U2=M1V1+M2V2

m-mass

u-initial velocity

v-final velocity

1-volleyball

2-basket ball dead center

so using the above formula

0.34×1.98+0.64×0=0.34×0.79+0.64×V2

to get

0.6732+0 = 0.2686+0.64V2

0.4046=0.64V2

divide both sides by 0.64 to get V2 which is the final velocity of basketball

0.6322m/s=V2

The final velocity of the basketball after the impact is 1.643 m/s west.

The given parameters;

mass of the volleyball, m = 0.34 kginitial velocity of the volleyball, u₁ = 1.98 m/smass of the stationary basketball, m₂ = 0.6 kgfinal velocity of the volleyball, v₁ = 0.79 m/s

The final velocity of the basketball after the impact is calculated by applying the principle of conservation of linear momentum;

m₁u₁  +  m₂u₂  =  m₁v₁   +  m₂v₂

0.34(-1.98) + 0.6(0) = 0.79(0.34) + 0.6(v₂)

-0.673 = 0.316 + 0.6v₂

-0.989 = 0.6v₂

[tex]v_2 = \frac{- 0.989}{0.6} \\\\v_2 = -1.643 \ m/s\\\\v_2 = 1.643 \ m/s \ west[/tex]

Thus, the final velocity of the basketball after the impact is 1.643 m/s west.

Pictured is an animal cell and a plant cell. Which organelle labeled in the plant cell produces the energy for the cell?

Answers

Answer:

Mitochondria

Mitochondria. Mitochondria are double membrane-bound cell organelles responsible for the supply and storage of energy for the cell.

Explanation:

The organelle labeled as "mitochondria" in the plant cell produces the energy for the cell through the process of cellular respiration.

What are mitochondria?

Mitochondria are organelles found in most eukaryotic cells. They are often referred to as the "powerhouses" of the cell because their main function is to produce energy in the form of ATP (adenosine triphosphate) through a process called cellular respiration.

Mitochondria have an outer membrane and an inner membrane with folds called cristae. The space between the two membranes is called the intermembrane space, while the space inside the inner membrane is called the mitochondrial matrix. The mitochondrial matrix contains enzymes and other molecules needed for the metabolic reactions of cellular respiration.

Cellular respiration is a process that converts glucose and oxygen into ATP, which is the primary energy source for cells. Mitochondria play a key role in this process by breaking down glucose through a series of chemical reactions that ultimately produce ATP. The energy stored in ATP molecules can then be used by the cell for various cellular processes, such as muscle contraction, protein synthesis, and the maintenance of the cell's membrane potential.

In addition to their role in ATP production, mitochondria are also involved in other important cellular functions, such as calcium signaling, apoptosis (programmed cell death), and the synthesis of certain lipids and heme groups. Mitochondrial dysfunction has been implicated in a number of diseases, including Parkinson's disease, Alzheimer's disease, and diabetes.

Therefore, Through the process of cellular respiration, the organelle in the plant cell known as the "mitochondria" generates the energy for the cell.
