The location in this diagram do the magnetic field lines show that the magnetic field is strongest is in C and wekeness in D.

The lines representing the magnetic field are closed, that is, they have no beginning or end. This can be observed when we place iron filings on a sheet of paper, over a bar magnet: the pattern of lines formed continues on the part of the paper that is on the magnet, closing.

In the region of the poles we see that the lines of magnetic induction are closer to each other, therefore, we consider that close to the poles the magnetic field is more intense. In this case it is stronger in C and weaker in D.

Explanation:

The amount of work must a 60 kg runner do to accelerate from rest to a velocity of 2 m/sec is 120 joules.

To find the work done, the given values are,

Mass = 60 kg

Velocity = 2 m/sec.

The amount of work can be expressed by the Kinetic energy of the runner. Energy can be defined as the capacity of an object or physical body to perform work. Thus, energy is typically measured in Joules (J).

Kinetic energy can be regarded as form of energy posses by an object when it's in motion.

Total energy = kinetic energy + potential energy

Thus, Kinetic Energy, KE = (1/2) (m) (v²)

KE =1/2 (60 kg) (2² m²/s²)

KE = 120 Joules.

That's the amount of energy that has to come from somewhere, in order to boost him to that speed.

The first star that formed in the Milky Way's history is believed to have been a Population III star, which formed approximately 100-300 million years after the Big Bang.

These stars are thought to have been composed almost entirely of hydrogen and helium, with trace amounts of lithium and beryllium. This is because these elements were the only elements present in the universe at the time of the star's formation.

The first stars formed from clouds of primordial gas that were almost entirely composed of hydrogen and helium, which were produced in the Big Bang. As the first stars began to form and undergo nuclear fusion, they produced heavier elements such as carbon, oxygen, and nitrogen, which were then incorporated into subsequent generations of stars.

Therefore, if we were able to measure the composition of the first star that formed in the Milky Way's history, we would expect it to have been composed almost entirely of hydrogen and helium, with trace amounts of lithium and beryllium. This composition would reflect the early stages of the universe when the only elements that existed were the lightest elements, which were produced in the Big Bang.

Answer:

The rate of change of distance is defined as speed.

Explanation:

The speed is defined as the rate of change of distance.

Speed = distance/ time

When we know the distance and the time, we get the value of speed. So, e know that who is moving fast or slow.

hen a graph is pltted beteen the distance and time, the slope of the graph gives the value of speed. So, by checking the slopes, hoseslope ismore, the speed is more and thusit is moving faster.

So, i agree with the statement.  

The calculate the object distance from the pole of the mirror, we can use the magnification formula: m = -v/u Where m is the magnification, v is the image distance, and u is the object distance.

The magnification is 3 and the image distance is 40 cm, we can solve for the object distance: 3 = -40/u = -40/3 u ≈ -13.3 c the negative sign indicates that the object is located in front of the mirror. To calculate the focal length, we can use the mirror formula: 1/f = 1/u + 1/v Where f is the focal length. We know that the image is upright, which means that the mirror is a concave mirror (since a convex mirror always produces a smaller, inverted image). For a concave mirror, the focal length is positive. Substituting the values we know, we get: 1/f = 1/-13.3 + 1/40 1/f ≈ 0.075 f ≈ 13.3 cm So the object distance from the pole of the mirror is approximately -13.3 cm, and the focal length of the mirror is approximately 13.3 cm.

The elevator accelerates with an acceleration of a=-2.45 m/s2 in a downward direction.

Any vector's magnitude, represented by its unit and pointing in the direction of the vector, is its length. As a result, the acceleration's magnitude is equal to the length of the acceleration vector and it is pointed in the same direction. For any vector quantity, this is true.

Three situations can be distinguished when figuring out the direction of acceleration: when picking up speed, the acceleration is in the direction of movement; when slowing down, the acceleration is in the opposite direction to the direction of movement; and when driving around a corner at a constant speed, the acceleration is in the direction of movement.

In order to produce a rainbow through a prism using white light, the index of refraction of the prism's material must vary with the wavelength of light. This results in violet light bending more than red light when passing through the plastic, causing the different colors to separate and create the rainbow effect.

1. In order to produce a rainbow through a prism using white light, the index of refraction of the prism's material must vary with the wavelength of light. This means that the prism material should have a property called dispersion, where the index of refraction increases as the wavelength of light decreases. When white light enters the prism, each color (wavelength) will bend (refract) at a slightly different angle due to this dispersion. As a result, the constituent colors of white light separate and form a spectrum, creating the appearance of a rainbow.

2. The index of refraction for clear plastic is greater for violet light compared to red light. This is because the dispersion property causes the index of refraction to increase as the wavelength of light decreases. Violet light has a shorter wavelength than red light, so it will experience a higher index of refraction within the clear plastic. This results in violet light bending more than red light when passing through the plastic, causing the different colors to separate and create the rainbow effect.

If tangential speed is 29.7 km/s, the orbital radius of Earth is approximately 1.49 x 10¹¹ meters.

The motion of Earth around the Sun can be described as circular motion, where the gravitational force of the Sun acts as the centripetal force. In this scenario, we are given the tangential speed of Earth and the centripetal acceleration acting on Earth, and we need to determine the orbital radius of Earth.

The formula for centripetal acceleration is:

a = v²/r

Where a is the centripetal acceleration, v is the tangential velocity, and r is the orbital radius.

We are given that the tangential speed of Earth is 29.7 km/s, which is equivalent to 29,700 m/s. We are also given that the centripetal acceleration acting on Earth is 5.9 x 10⁻³ m/s².

Plugging in the values, we get:

5.9 x 10⁻³ m/s² = (29,700 m/s)² / r

Solving for r, we get:

r = (29,700 m/s)² / (5.9 x 10⁻³ m/s²)

r = 1.49 x 10¹¹ meters

Yes, melting lead into a liquid to form pellets is a physical change.

This is because the chemical composition of lead remains the same even after it has been melted and then solidified into pellets. In other words, the molecular structure of lead does not change during the melting process, but only the physical state of the material changes from a solid to a liquid and then back to a solid. This type of change is reversible and can be undone by cooling the lead pellets to their solid state. Therefore, melting lead to form pellets is an example of a physical change rather than a chemical change.

In the peak of summer, it hasn't rained in a week, and the plants are looking rough, so watering the plants for an hour is a good idea.

However, the next day, you come back to the garden, and the plants look in worse shape than they did previously, as if none of that water made it to the plant. Plants absorb water through their roots. The root system of a plant is responsible for drawing water and nutrients from the soil. A plant's root system must be able to absorb water quickly in order for the plant to grow and thrive. When the soil around the root system is dry, the roots will stop growing and will not be able to absorb water.

It may even start to die. Watering plants during the peak of summer is important because it will help keep the soil moist and prevent the roots from drying out. However, watering a plant too much can be harmful. If a plant is overwatered, the water may not be able to penetrate the soil and reach the roots. Instead, it may just sit on top of the soil, causing the roots to rot and die. This can cause the plant to wilt and die.To summarize, if the soil around the plant is too dry, the roots may not be able to absorb the water you gave them, causing the plant to look worse than before. Conversely, overwatering can also be harmful because the water may not be able to penetrate the soil and reach the roots, causing the roots to rot and die.

Answer:

166 cm

Explanation:

Given :

d1 =109cm

M1= 45kg

M2=29000g = 29 kg

As we know that Newton second law

\(Force\ =\ Mass\ *\ Acceleration\)

Here M1= 45kg  

and acceleration=\(9.81 m/s^{2}\)

Therefore

\(F1=45 * 9.81\)

\(F1= 441.45 N\)

M2=29000g = 29 kg

Similarly

\(F2= 29 * 9.81\\ F2= 284.4 N\)

Now we using the Principal of moments

\(F1 * d1 =F2 *d2\)

\(441.5 * 109\ =\ 290\ *\ d2\\48,123.5=290 d2\\d2 =165.9\)

~ d2=166 cm

To calculate the peak flow rate of the sewer, we need to determine the total volume of runoff from the different areas and then divide it by the time it takes for the runoff to reach the sewer. Therefore, the peak flow rate of the sewer is approximately 7 meters per second.

First, let's calculate the total volume of runoff from each area:

Residential area:

Runoff coefficient = 0.7

Area = 3 km²

Volume of runoff from residential area = Runoff coefficient × Area

= 0.7 × 3 km²

= 2.1 km³

Commercial area:

Runoff coefficient = 0.8

Area = 2 km²

Volume of runoff from commercial area = Runoff coefficient × Area

= 0.8 × 2 km²

= 1.6 km³

Green area:

Runoff coefficient = 0.5

Area = 1 km²

Volume of runoff from green area = Runoff coefficient × Area

= 0.5 × 1 km²

= 0.5 km³

Now, let's calculate the total volume of runoff from the entire town:

Total volume of runoff = Volume of runoff from residential area + Volume of runoff from commercial area + Volume of runoff from green area

= 2.1 km³ + 1.6 km³ + 0.5 km³

= 4.2 km³

Next, let's convert the volume of runoff to a flow rate by dividing it by the time it takes for the runoff to reach the sewer:

Time of concentration = 10 minutes

Length of the sewer = 3,000 meters

Flow rate = Total volume of runoff / Time of concentration

= 4.2 km³ / (10 minutes / 60 minutes/hour)

= 4.2 km³ / (0.167 hours)

= 25.15 km³/hour

Finally, let's convert the flow rate to meters per second:

Flow rate in meters per second = Flow rate in km/hour × (1,000 meters / 1 kilometer) × (1 hour / 3,600 seconds)

= 25.15 km/hour × (1,000 meters / 1 kilometer) × (1 hour / 3,600 seconds)

= 7 meters/second

Find: v

v = at + v₀

v = (-10 m/s²) (1.0 s) + 25 m/s

v = 15 m/s

Answer: Force

In physical science, a force is something that acts on an object by pushing or pulling it. If the force is strong enough, it changes the position or shape of the object. Forces such as friction, air resistance and simple physical contact touch the object directly, while forces like gravity, magnetism and electrostatics act on the object from a distance. Force is a vector quantity, meaning you can measure both its strength and its direction. The formula to find the measure of a force is force = mass times acceleration, written as f = ma.

Velocity

The faster something is moving, the higher its velocity.

When an object is moving, one way to measure how fast it is moving is by finding its velocity, which is the rate at which it is changing position. Like force, velocity is a vector quantity, so it includes direction. To find the average velocity of an object, divide the change in its position by the time the movement took, and state its direction. For example, if a car is driving north and in one hour's time it travels 30 miles, its velocity is 30 miles per hour, north.
