water is 1000 kg/m3 while air is 1.225 kg/m3

Boiling water is a common method used to sterilize water that may be contaminated. subjecting microbes to such high temperatures is an example of a(n) microbicidal technique.

A substance that eliminates microorganisms (such as bacteria) is known as microbicide and the techniques that involve destruction of microbes are known as microbicidal techniques.

The pathogen biofilm was effectively destroyed by the combined microbicidal effects of hot water (50, 60, or 70 °C) and 2% citric acid. It was discovered that the combination of hot water and citric acid caused sub-lethally harmed cells.

A fairly easy way to disinfect water is to boil it. The majority of dangerous organisms, notably viruses and bacteria that cause waterborne infections, are killed when water is heated to a high temperature of 100°C. The water must boil for at least 20 minutes in order to be most effective.

Hence, water that may be polluted is frequently sterilized by boiling. Using such high temperatures to kill germs is an example of a microbicidal method.

Crest is the part of the wave which does this.

A sound wave is the sample of disturbance resulting from the movement of strength visiting through a medium, including air, water or every other liquid or stable remember as it propagates far from the supply of the sound.

The sound waves are generated by a sound source, such as the vibrating diaphragm of a stereo speaker. The sound source creates vibrations in the surrounding medium. because the supply continues to vibrate the medium, the vibrations propagate far from the supply at the rate of sound, hence forming the sound wave.

A sound wave is not a transverse wave with crests and troughs, however alternatively a longitudinal wave with compressions and rarefactions.

Answer:

F = 878.9 N

Explanation:

The electrostatic force of attraction or repulsion is given by Coulomb's Law as follows:

F = kq₁q₂/r²

where,

F = Force pf repulsion between balloons = ?

k = Coulomb's Constant = 9 x 10⁹ N.m²/C²

q₁ = q₂ = magnitudes of 1st and 2nd charge = 0.0025 C

r = distance between balloons = 8 m

Therefore,

F = (9 x 10⁹ N.m²/C²)(0.0025 C)(0.0025 C)/(8 m)²

F = 878.9 N

The magnitude of the electrical force of repulsion between them is F = 878.9 N

Here we use Coulomb's Law

F = kq₁q₂/r²

Here,

F = Force of repulsion

k = Coulomb's Constant = 9 x 10⁹ N.m²/C²

q₁ = q₂ = magnitudes of 1st and 2nd charge = 0.0025 C

r = distance between balloons = 8 m

So,

F = (9 x 10⁹ N.m²/C²)(0.0025 C)(0.0025 C)/(8 m)²

F = 878.9 N

Hence, The magnitude of the electrical force of repulsion between them is F = 878.9 N

To decrease power output while still doing the same amount of work, one can increase the time it takes to complete the task. This means that the work is being spread out over a longer period of time, reducing the amount of power required to complete it.


There are several ways to increase the time it takes to complete a task, such as taking more breaks, slowing down the pace of work, or breaking the task up into smaller parts. For example, if you are lifting weights, you can decrease the power output by doing more repetitions with a lighter weight, or by taking longer breaks between sets. This will still allow you to achieve the same amount of work, but with less power output.
Another way to decrease power output is to use more efficient equipment or techniques. For example, if you are using a lawn mower, switching to a more energy-efficient model or using a mulching blade can reduce the amount of power needed to mow the lawn. Additionally, adjusting the technique used to complete a task can also make it more efficient and require less power.
In conclusion, decreasing power output while still doing the same amount of work can be achieved by increasing the time it takes to complete the task, using more efficient equipment or techniques, or breaking the task up into smaller parts.

The speed of the ball just before it strikes the ground is 46.4 m/s

Motion under gravity is also known as vertical motion. The gravity act only on the vertical component of the velocity.

Given that a ball is thrown horizontally from the top of a building 110 m high. The ball strikes the ground 74 m horizontally from the point of release.

The time taken for the ball will be

h = ut + 1/2gt²

but u = 0

110 = 1/2 × 9.8 × t²

110 = 4.9t²

t² = 110 / 4.9

t² = 22.45

t = √22.45

t = 4.74 s

The speed of the ball just before it strikes the ground will be

v² = u² + 2gH

v² = 0 + 2 × 9.8 × 110

v² = 2156

v = √2156

v = 46.4 m/s

Answer: It produces uneven heating of Earth's surface by the sun

Explanation:

The Earth's tilt affect the climate by producing uneven heating of the Earth's surface by the Sun. Thus, the correct option is A.

The earth's spin axis is tilted with respect to the orbital plane of the planet. This is what actually causes the change in seasons. When the earth's axis points are towards the sun, it is summer for that hemisphere. However, when the earth's axis points are away, winter season can be expected.

The greater the Earth's axial tilt angle, the more extreme will be the seasons are, as each of the hemisphere receives more solar radiation during its summer season, when the hemisphere is tilted towards the Sun, and less during the winter season, when it is tilted away.

Explanation:

The average velocity over those 4 seconds is the velocity after 2 seconds:

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:

a) F = 40 N

b) It is acting towards left

c) a = 10 m/s²

Explanation:

As the block of mass and its forces are not shown, the question is incomplete.

First we attach the diagram of the attached question (See below)

We can see in the diagram that there are total of 5 forces acting on that block. Consider the forces acting towards right to be positive and the forces acting towards left be negative (or vice versa, the answer would be same). Let them be:

F₁ = 10 N

F₂ = 17 N

F₃ = 21 N

F₄ = -35 N

F₅ = -53 N

To find resultant force, we'll add all of the 5 forces.

Resultant Force = F₁ + F₂ + F₃ + F₄ + F₅

Resultant Force = 10 + 17 +21 - 35 - 53

Resultant Force = -40 N

As the resultant force has a negative sign, and previously we stated that the forces acting towards left are negative, so the Resultant Force is acting in the left direction.

We know that

F = (m)(a)

Where F is the resultant force we found. Resultant Force was -40N , where negative sign only represents the direction. We'll consider only the magnitude which is 40N, where m is the mass of the block which is 4 kg. Substitute in the equation.

40 = (4)(a)

a = (40)(4)

a = 10 m/s² (in left direction)

Answer:

91.3 kg

Explanation:

weight = m*g

m: mass

g: gravity = 9.8 or 10 (depends on what your instructor tells you to use)

mass = w/g

Wave speed (S) decreases, wavelength (L) decreases, height (H) increases, and wave steepness (\(\frac{H}{L}\)) increases when  the wave moves across shoaling water to break on the shore.

The distance a wave travels in a given amount of time, such as the number of meters per second, is referred to as its wave speed. The equation Speed = Wavelength x Frequency relates wave speed to wavelength and frequency. When the wavelength and frequency are known, this equation can be used to calculate wave speed.
