Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.

Explanation:

Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping

Explanation: COMPOST BIN

WHAT IS A COMPOST BIN?

A compost bin is a container into which you place organic waste to turn into compost (organic material) over time.

Most compost bins are designed to hasten the decomposition of organic matter through proper aeration and moisture retention. With the proper combination of air and moisture, ideal conditions are produced for the activity of aerobic organisms responsible for the high temperatures that transform the organic materials into compost

Read on to find out how to start a compost bin, DIY compost bin ideas, and more tips for beginners.

The decomposition process will eventually take place over time in a compost "pile" or "heap," even without any housing to contain the matter. However, a compost bin is worth it because it helps speed up decomposition and keeps the area neat. Some bins are continuous, meaning you can keep adding waste to them, while others create batches of compost with a set mix of ingredients you add all at once. Depending on the style of compost bin you choose, bins can also have the advantage of making it harder for rats to get at your compost. This is true of the tumbler type, for example.

CHOOSING THE RIGHT BIN

Select the right bin for your composting needs. You can make an inexpensive compost container out of almost any container or material. Some ideas include:

Plastic storage container

Plastic bucket

Trash cans

Straw bales

Lumber

Branches harvested from the woods

Stone

Cinder blocks

Wire fencing

Ceramic (also popular for a kitchen countertop compost bin)

The best bin, however, is one you can easily turn or rotate consistently to control odors and make sure all the materials decompose. This is especially important for aerobic composting (more information below). A tumbler composting bin is pricey, but you can DIY one from barrels and sawhorses. You can turn compost with a rake or shovel in a non-rotating bin, it just takes more labor to do so.

Explanation:

The vomeronasal organ is situated in the top of a snake's mouth, and there are two little section openings that lead to it - like nostrils, however within the mouth. When the snake has waved its forked tongue around to the point of getting a decent covering of synthetic substances, it brings the tongue once more into the mouth and presses the tips of its forks against the organ - one fork tip in each opening. This conveys a message to the snake's cerebrum, telling it what the "smell" is. What's more, assuming the sign is more grounded on one tip of the tongue fork than the other, it lets the snake know which course that smell is coming from. This is the manner by which snakes can track down secret prey. To realize how snakes murmur,

The bottom wave has a greater frequency.

Explanation:

1. Waves with a low frequency have a longer wavelength.

2. Waves with a high/great frequency have a shorter wavelength.

The bottom wave has a greater frequency. So, the second option is correct.

Frequency of a wave is defined as the number of oscillations the wave completes in one second.

Here,

The diagrams of two waves are represented. The propagation of wave from the time zero to one second is given.

From the first diagram,

The wave is travelling from point a at t =  0 and reached at the point b at t = 1 s. This means in a time duration of 1 second, it has travelled a distance ab from a to b. The time taken for one oscillation to complete is called the time period. In the diagram, the number of waves passing in one seconds can be calculated. A few number of waves passed in one second.

From the second diagram,

The wave is travelling from the point a to point b in a time duration of one second. When compared to the top wave, the time taken for one wave to complete is lesser for the bottom wave. That means the time period is lesser than the top wave. In the diagram, it can be seen that, the number waves that has been completed in the one second is very high compared to that of the top wave. That means the bottom wave has higher frequency than that of the top wave.

Hence,

The bottom wave has a greater frequency.

Answer:

UV radiation is widely used in industrial processes and in medical and dental practices for a variety of purposes, such as killing bacteria, creating fluorescent effects, curing inks and resins, phototherapy and suntanning.

Explanation:

The velocity of the vehicle is equal to 406.5 m/s. The velocity in Km/hr is 1463.4 Km/hr.

Velocity can be demonstrated as a vector measurement of the direction of the object and the rate of motion of an object. The velocity of an object can be described as the change in the body's position w.r.t. time.

Velocity can be expressed as a vector quantity as it consists of magnitude as well as direction. A mathematical formula common and simplest way to find velocity.  

v = d / t

Where v is the velocity, d is the distance covered and t is the time taken by the body.

The S.I. unit for velocity can be represented as m/s and can be expressed in terms of miles per hour (mph), and kilometers per hour (kph).

Given, the distance traveled by the vehicle, d = 100 m

The time taken by vehicle = 0.246 sec

The velocity of the vehicle, v = 100/0.246 = 406.5 m/s

We know that 1km = 1000m then 1 m = 10⁻³ Km  

1 hour = 60 ×60 = 3600 s

1s = 1/3600 hr

Therefore, velocity, \(\displaystyle v = 406.5 \times \frac{3600}{1000} Km/hr\)

v = 1463.4 Km/hr

The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J

Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.

mass(m)  = 10kg

g (acceleration due to gravity) = 9.8m/s^2

altitude(height (h)) = 400m

Meteor's Potential energy = m * g * h

                                           = 10 * 9.8 * 400 = 39200 J

To find the volume of the block, subtract the initial water volume from the final water volume, convert the change in water volume to cubic centimeters, and consider it as the volume of the block.

To find the volume of the block using the measurements provided.

1. Calculate the change in water volume:

The initial water volume is given as 62.3 mL, and the final water volume is given as 89.5 mL. To determine the change in water volume, we subtract the initial volume from the final volume: 89.5 mL - 62.3 mL = 27.2 mL. This value represents the increase in water volume caused by placing the block in the graduated cylinder.

2. Convert the change in water volume to cubic centimeters:

Since 1 mL is equivalent to 1 cubic centimeter (cc), we can directly convert the change in water volume from milliliters to cubic centimeters. In this case, the change in water volume is 27.2 mL, which is also equal to 27.2 cc.

3. Determine the volume of the block:

When the block is placed in the graduated cylinder, it displaces some amount of water, resulting in an increase in water volume. By measuring this increase in volume, we can determine the volume of the block itself. In this case, the change in water volume of 27.2 cc represents the volume of the block.

By following these steps, we can find the volume of the block based on the provided measurements.

Therefore, By deducting the initial water volume from the final water volume and converting the difference in water volume to cubic centimeters, the block's volume can be calculated. the volume of the block is 27.2 cc.

Answer:

1. She is moving at a speed of \(147.18 ms^{-1}\).

2. The speed of the golf ball is \(78.1 m/s\).

Explanation:

1. We can say , at any moment the skydiver is having a kinetic energy of \(1/2 mv^2\)

(where, \(m\) is her mass and \(v\) is the velocity at that point)

Given, \(1/2mv^2 =704000\)

and, \(m = 65KG\)

So, putting the values we get,

\(v=147.18 ms^{-1}\)

2. \(KE=\frac{1}{2} mv^2\)

\(143.3J =\frac{1}{2} (.047)v^2\)

\(v^2=6097.9 m^2/s^2\)

\(v=78.1 m/s\)

In 1848, Kelvin used this as a basis for an absolute temperature scale. He defined "absolute" as the temperature at which molecules would stop moving, or "infinite cold." From absolute zero, he used the same unit as Celsius to determine the increments.

Absolute zero cannot technically be achieved. However, scientists have been able to lower the temperature of matter to just a fraction of a Kelvin above absolute zero through techniques such slowing down particles using lasers.
