Answer:
it grabs unto soil and keeps it clamped together it prevents this makes the soil harder to wash away
Answer:
When the leftovers are left in the autumn, they have two purposes:
- Preventing erosion; the roots remain in the ground, so they hold it tightly till the next planting of the crops.
- Fertilizing the soil with natural material; the roots will not rot quickly in the colder period of the year, but will start rotting much faster in the spring, thus they will enrich the soil.
why is clay soil chosen for earthenware? Explain it.
There are many reasons actually...
◇ Clayey soil is easy to mould than the other soils.
The other soils (like sandy soil & loamy soil) are grainy or dry in nature & cannot be moulded. In the ancient times, when technology & the know-hows were still not introduced, people used clayey soul to make earthern pots to store stuff. This practice still continues even today.
◇ It keeps water cool.
Ever wondered why water stored in the earthenware remains cool even on a sunny day? It's because the heat required for evaporation is taken from water inside the pot & thus it cools the water stored inside.
◇ Clayey soil is also moist, durable, more plastic like & easy to retain making it ideal for potters to make earthenware.
__________
Clay soil is used to make earthenwares because, clay can be easily molded to desired sizes and shapes. Clay absorbs water moiety and make the pot very cool inside.
What is clay?Clay is a type of soil made by the sedimentation process near water resources. They are rich in minerals. Clay is rich in silicates and intermolecular force in the soil is comparatively less and can be easily molded any shape and size.
When clay is fired to a high enough temperature, the glass-forming materials in the ceramic form a liquid glass. This glass bridges the gaps between the clay particles. As the pottery cools at the end of the firing process, the glass between the clay particles solidifies again.
Clay pots make the water cooler inside. Hence, clay is used to make earthen wares.

Define power and explain how to determine power. (4 points)
The definition of power is operating electrically or having strength or force. An example of power is the functioning of a gasoline-driven saw or tool. Or Power is related to other quantities; for example, the power involved in moving a ground vehicle is the product of the traction force on the wheels and the velocity of the vehicle. The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft. Likewise, the power dissipated in an electrical element of a circuit is the product of the current flowing through the element and of the voltage across the element.

A4 m high tank filled with water is drilled with four identical small holes at 1 m, 1.5 m, 2 m and 2.5 m from the bottom of tank, the speed of efflux will be greatest from the hole at?
Answer:
at 2.5m
Explanation:
because 2.5m*4m is 10.0=10
To solve this, we must know each and every concept related to speed of efflux and its calculations. Therefore, hole at 3m will have the greatest speed of efflux.
What is speed of efflux?The velocity of outflow is the speed with which a liquid emerges from a hole cut at a certain height from bottom of the container within which the liquid is contained.
Mathematically, the formula for speed of efflux can be given as
speed of efflux =√2×g×h
g= acceleration due to gravity
h1=4- 1 =3m
h2=4-2=2m
h3=4-2.5=1.5m
h4=4-1.5=2.5
Since speed of efflux is directly proportional to height. More the vale of h more will be speed of efflux. So on calculations, hole at 3m will have the greatest speed of efflux.
Therefore, hole at 3m will have the greatest speed of efflux.

A Their magnetic fields increase with size.
B The attractive force of their magnetic
fields is greatest at the poles.
C The attractive force of their magnetic
fields is greatest at the center.
D Electric current causes them to lose
magnetism
Answer:
C
Explanation:
The attractive force of their magnetic fields is greatest at the poles. Option B is correct.
Earth's magnetic field is similar to that of a bar magnet in that both have north and south poles. The magnetic field lines of both Earth and a bar magnet originate from the north pole and loop around to the south pole. The magnetic field lines are most concentrated and the attractive force is strongest near the poles of both Earth and a bar magnet.
At the poles, the magnetic field lines are densely packed and closely spaced, leading to a stronger magnetic force. This is why compass needles, which align with Earth's magnetic field, point towards the magnetic north pole.
The statement about electric current causing them to lose magnetism (option D) is not accurate. Electric current can actually create magnetic fields, as seen in electromagnets. Earth's magnetic field is generated by the movement of molten iron in its outer core, not by electric currents in the conventional sense.
In summary, option B is the correct answer as it accurately reflects the similarity in the distribution of magnetic field lines and the strength of the attractive force near the poles for both Earth and a bar magnet.

Answer:
C
Explanation:
The correct answer is C because it puts equivalent measurements in the equivalent cup size. Both cups in answer C are the same measurement: 200 mL. The water in both cups is also the same measurement: 100 mL of 70 degrees Celsius. This is important because equivalent measurements for everything mean the experiment will be fair, equal, and accurate. If the measurements were not equal to each other, your experiment would not be as accurate.
A cyclist pedals up to the top of a hill.
a) What kind of energy is being used to do work against gravity?
b) State the type of energy the cyclist has when he stops at the top of the hill.
c) When the cyclist moves downhill without pedaling, what type of energy does he gain?
Explanation:
A) kinetic energy
B) potential energy
C) Mechanical energy
a) The motorcyclist rises utilising chemical energy's "mechanical energy" (kinetic and potential energy). b) The cyclist's highest "gravitational potential energy" is transformed into motion downhill. c) When the rider moves downhill, potential energy becomes "kinetic energy." "Kinetic energy" is most vital.
a) "Mechanical energy" is used by the cyclist to ride up the slope. Kinetic and potential energy from an object's motion and position make up mechanical energy. As they pedal, cyclists transform chemical energy from their bodies into mechanical energy. This mechanical energy overcomes gravity as the cyclist climbs. As the cyclist climbs, potential energy accumulates, which is translated into kinetic energy as they descend.
b) At the summit of the slope, the biker has "gravitational potential energy." An object's gravitational potential energy depends on its position in a gravitational field. The biker has gained potential energy by climbing against gravity. At the crest of the hill, the cyclist's kinetic energy is lowest while potential energy is highest. The cyclist's potential energy is ready to be turned into kinetic energy as they descend.
c) Without pedalling, the rider gains "kinetic energy." The cyclist's speed increases as they descend, converting potential energy into kinetic energy. The cyclist's potential energy is turned into kinetic energy by gravity. As the rider descends, their potential energy diminishes but their kinetic energy increases, speeding up their bike. The biker converts potential energy into kinetic energy as he descends, and most of it is converted back at the bottom.
In conclusion, the cyclist climbs the incline using "mechanical energy" from chemical energy. They descend using "gravitational potential energy" at the top. Potential energy becomes "kinetic energy" when the rider descends without pedalling, speeding up the bike. Potential-to-kinetic energy conversion helps the cyclist climb the slope.

Let's consider the given terms ~
Initial velocity (u) = 100 m/sAcceleration (a) = - 10 m/s²(Acceleration is negative bbecause train slows down)
Final velocity (v) = 0 m/s(final velocity is 0, because train stops)
Now, let's find the time taken (t) by using the first equation of motion ~
