The average speed of the baton can be determined by dividing the total distance travelled by the total time taken for that travelling.

[tex]Average\ Time = \frac{Total\ Distance}{Total\ Time}[/tex]

First, we will find the total distance, by adding the distances travelled by both Mahiya and Mrinmoy, while carrying the baton.

[tex]Total\ Distance = Distance\ Travelled\ by\ Mahiya\ to\ pass\ the\ baton\ to\ Mrinmoy\ +\ Distance\ Travelled\ by\ Mrinmoy\ to\ pass\ the\ baton\ to\ Mahiya\ +\ Final\ Distance\ Travelled\ by\\ Mahiya[/tex]Total Distance = 60 m + 120 m + 60 m = 240 m

Now, we will find the total time taken for this travelling. To find out the total time we will divide each distance travelled by the speed of the traveller during that distance:

[tex]Total\ Time = \frac{60\ m}{6\ m/s}+\frac{120\ m}{4\ m/s}+\frac{60\ m}{3\ m/s}\\\\Total\ Time = 10\ s\ +\ 30\ s\ +\ 20\ s[/tex]

Total Time = 60 s

Now, we finally find the average speed of the baton by using the formula:

[tex]Average\ Time = \frac{Total\ Distance}{Total\ Time}\\\\Average\ Time = \frac{240\ m}{60\ s}[/tex]

Average Speed = 4 ms⁻¹

2 soil amelioration

3 increasing production

4 slow release.

Answer:

How does fertilizer affect plant growth?

Explanation:

Answer:

196000 N

Explanation:

The following data were obtained from the question:

Height (h) = 10 m

Area (A) = 2 m²

Force (F) =.?

Next, we shall determine the pressure in the tank.

This can be obtained as follow:

P = dgh

Where

P is the pressure.

d is the density of the liquid.

g is acceleration due to gravity

h is the height.

Height (h) = 10 m

Density (d) of water = 1000 kg/m³

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

Pressure (P) =...?

P = dgh

P = 1000 × 9.8 × 10

P = 98000 N/m²

Therefore, the pressure acting on the tank is 98000 N/m²

Finally, we shall determine the force of gravity acting on the column of water as follow:

Area (A) = 2 m²

Pressure (P) = 98000 N/m²

Force (F) =.?

Pressure (P) = Force (F) /Area (A)

P = F /A

98000 = F/ 2

Cross multiply

F = 98000 × 2

F = 196000 N

Therefore, the force of gravity acting on the column of water is 196000 N

Answer:

θ = 36.9°

N = 240 N

R = 120 N

Explanation:

Draw a free body diagram.  There are five forces on the ladder:

Weight force mg pulling down at the center of the ladder,

Normal force N pushing up at the ground,

Friction force Nμ pushing right at the ground,

Reaction force R pushing left at the wall,

and friction force Rμ pushing up at the wall.

Sum of forces in the x direction:

∑F = ma

Nμ − R = 0

R = Nμ

Sum of forces in the y direction:

∑F = ma

N + Rμ − mg = 0

N + Nμ² − mg = 0

N (1 + μ²) = mg

1 + μ² = mg / N

Sum of torques about the base of the ladder.

∑τ = Iα

mg (L/2 cos θ) − R (L sin θ) − Rμ (L cos θ) = 0

mg (L/2 cos θ) = R (L sin θ) + Rμ (L cos θ)

mg (1/2 cos θ) = R (sin θ + μ cos θ)

mg / 2 = R (tan θ + μ)

mg / (2R) = tan θ + μ

Substitute:

mg / (2Nμ) = tan θ + μ

(1 + μ²) / (2μ) = tan θ + μ

(1 − μ²) / (2μ) = tan θ

Given μ = 0.5:

tan θ = (1 − 0.5²) / (2 × 0.5)

tan θ = 0.75

θ = 36.9°

The reaction forces are:

N = mg / (1 + μ²) = 240 N

R = Nμ = 120 N

The global economy is heavily reliant on the service sector, which accounts for more than two-thirds of global GDP, over three-quarters of foreign direct investment in advanced nations, the majority of worker employment, and the majority of job growth. Thus, option B is correct.

The service sector, often known as the tertiary sector, makes up the third tier of the three-sector economy. Instead of creating products, this sector provides training, consulting, and maintenance and repairs.

The GDP of the nation is significantly impacted by the service sector. Through trade in services, it not only generates many jobs, but also significantly improves the country's economic performance.

Therefore, 70% of GDP is made up of consumer expenditure. The retail and service sectors are important to the American economy.

Answer:

a) according to Faraday's law , b) creating a faster movement, placing more turns on coil

Explanation:

a) The voltage is induced in the coil by the relative movement between it and the magnet, therefore according to Faraday's law

           E = - d (B A) / dt

In this case, the magnet is involved, so the value of the magnetic field varies with time, since the number of lines that pass through the loop changes with movement.

This voltage creates a current that charges the battery

b) There are several ways to increase the voltage

* creating a faster movement, can be done by the user

* placing more turns on the coil, must be done by the manufacturer

Answer:

C deceive participants

Explanation:

It is ethical practice to come clean or tell the truth about being deceptive at the end of the study.  They need to be told that they were deceived.  

In order to stop experimental subjects from trying to confirm the scientist's hypothesis, psychologists sometimes deceive participants about the true purpose of the experiment. The correct option is C.

Psychologists can help people learn to cope with stressful situations, overcome addictions, manage chronic illnesses, and administer tests and assessments that can aid in the diagnosis of a condition or reveal more about a person's thoughts, feelings, and behaviors.

Psychotherapy can be aided by both psychologists and psychiatrists.

However, most psychiatrists treat patients primarily through medication, whereas psychologists primarily treat patients through talk and/or behavioral therapy.

People seek the help of a clinical psychologist to deal with mood-related issues such as depression, mania, anger, or anxiety.

Psychologists sometimes deceive participants about the true purpose of the experiment in order to prevent experimental subjects from attempting to confirm the scientist's hypothesis.

Thus, the correct option is C.

Answer:

0.0025 kilograms

Explanation:

There are a 1000 grams in 1 kilogram, so that means that there are

0.0025 kilograms in 2.5 grams.

Answer:

Below

Explanation:

● 1 kg = 1000 g

Divide both sides by 1000

● 1/1000 kg = 1000/1000 g

● 0.001 kg = 1 g

Multiply both sides by 2.5

● 2.5 g = 0.001 × 2.5 kg

● 2.5 g = 2.5 × 10^(-3) kg

● 2.5 g = 0. 00 25 kg

Answer:

Electrons surrounding a nucleus are attracted to the protons within it because electrons and protons have opposite charges. Electrons closest to the nucleus are attracted with such a force that they can’t escape from the atom. These electrons tend to shield the protons from electrons that are farther away because electrons have the same charge and repel each other. Electrons that are farther away have less attraction to the protons within the nucleus and are more likely to be detached from the atom.

Electrons can be transferred from atoms of one body to atoms of another body through friction. This can occur when one body is rubbed against another or when a liquid flows across a solid. In either case, one body may be given a positive charge while the other body is given a negative charge of the same magnitude. Both charges are developed at the same time. Electrons can also be transferred from one body to another when a charged body comes into contact with an uncharged body. The electrons move in the direction that will equalize the charges; thus, the uncharged body will be given the same charge as the charged body.

Free electrons move from points of negative charge to points of positive charge. When these electrons move freely from one point to another with little resistance, the material they’re traveling through is said to be a conductor. Conductors have a large number of free electrons. Insulators, on the other hand, have very few free electrons and offer great resistance to the movement of these electrons. Electric charges produced on one end of a body composed of insulating materials will most likely not spread throughout the body. In a conductor, this charge would spread throughout the entire body. Metals are generally conductors; oils, rubber, air, porcelain, and plastics are good insulators.

Lightning is produced by the rapid transfer of free electrons when one of the following conditions exist:

One part of a cloud is positively charged and a neighboring part of the same cloud is negatively charged.

A positively charged cloud comes near a negatively charged cloud.

A cloud with either a positive charge or a negative charge comes near the earth.

Explanation:

Free electrons are abundant in conductors. Conversely, insulators provide a high level of barrier to the movement of these free electrons, since they have some of them. In a body made of insulating materials, electric charges generated on one end are likely to remain localized there.

Electrons can move freely between particles when they are in conductors, which are substances. The charge can be transported across the whole surface of an object constructed of a conducting substance.

Because distant electrons have the same charge as these nearby ones and resist one another, these electrons usually act as a shield for protons. Further distant, electrons are less attracted to the nucleus's protons and are therefore more prone to break away from the atom.

Free electrons migrate from negatively charged to positively charged locations. The substance these electrons are passing through is referred to as a conductor when it allows them to go easily from one location to another with little resistance. Electrons are abundantly free in conductors.

A body made of insulating materials will likely not conduct electricity when it generates charges on one end. This charge would permeate the entire body of a conductor. Oils, rubber, air, porcelain, and plastics are effective insulators while metals are typically conductors.

Answer:

600 mC

Explanation:

The charge of an electron is 1.6 x 10-19C so for a current with 10 mA, the charge going to screen in one second is 10 mC

so number of electrons, n = (10 x 10-3)/(1.6 x 10-19) = 6.25 x 1016  so in a minute the charge is 10 * 60 = 600 mC

Answer:

Total charge, q = It = 10 A x 60 s = 600 C

We know that, q = ne

So no. of electrons, n = q/e = 600 / (1.6×10-19) = 375x1019
