The chance that one, and only one, of the dice will land acer is It could boost the river's erosive force and flow rate.

When water from rain, snowmelt, and groundwater is brought to the surface, steam flow starts. Drainage systems are created in a way that effectively removes water from the land. Moving sheetwash, a thin water surface layer, is where streamflow starts. As it descends the sharpest slope, the water begins to erode the surface by forming tiny rill channels. Larger channels form as the rills merge, deepen, and downcut. Headward erosion, often known as rapid erosion, lengthens the channel upslope. Smaller tributaries join a bigger stem stream as neighboring channels merge over time.

Answer:

In a longitudinal wave, the medium or the channel moves in the same direction with respect to the wave. Here, the movement of the particles is from left to right and forces other particles to vibrate. In a transverse wave the medium or the channel moves perpendicular to the direction of the wave.

Explanation:

The shape of municipal water tank has the same shape as a drop of water resting on a nonabsorbent surface, such as a wax paper.

The engineers design the tank in this manner because:

A cylindrical water tank is more economical to build than others because it requires less construction material. The main reason is that it has the smallest possible girth-to-area ratio than a box-shaped tank. Here you can save costs.

Since circular structures minimize the surface area that heat radiates from, the water temperature remains more stable than other structures such as a square or rectangle. It therefore remains less affected by changing outside temperatures and keeps the water cooler in summer and warmer in winter.

According to Monolithic, the round structure is the strongest geometric structure than the square. Thus, a cylindrical water tank can withstand all external forces, such as strong wind or heavy rain, better than a square or rectangular tank. Thanks to this, the tank lasts longer.

Cylindrical tanks are comparatively easier to clean than tanks with corners. Therefore, the water remains more hygienic in round water tanks than others.

The change his direction from the intersection where the traffic light is located is 5m in south direction.

The displacement covered by a body per unit time is defined as its velocity. Velocity is a vector quantity that indicates the magnitude of the body's speed as well as the direction in which the body is moving. As a result, the velocity of an object can provide us with the direction of motion of the body.

Acceleration can now be defined as the rate at which an object's velocity changes per unit time. The particle's velocity rises with time in the direction of acceleration. Again, if acceleration is perpendicular to velocity direction, the body moves in a circular route. As a result, acceleration can also indicate the direction of motion of a body.

The process of gravitational collapse does not work in the silicon-fusion cycle that produces iron. It is because the iron nuclei do not have sufficient energy and therefore will not produce the additional gas pressure to halt the collapse.

The gravitational collapse process is a process during which astronomical objects such as massive stars contract due to their own gravitational pressure.

The gravitational pull draws the matter to the core of the object thus increasing energy generation which in turn increases the temperature of the central part of the object.

Due to this fundamental process, the old structure collapse, and new structure are formed in the universe.

The acceleration of the car will be -5.68 m/s, and it travels 13.76 m before stopping.

Acceleration is the general term for any process where the velocity changes. There are only two ways to accelerate: either by increasing speed or decreasing direction, or both. The reason for this is that velocity includes both a speed and a direction.

You cannot possibly be accelerating if you don't also change your direction and speed, regardless of how swiftly you are travelling.

It is a vector quantity with m/s² as its SI unit.

According to the question, the given values are :

Initial speed, u=12.5 m/s,

Final speed, v=0 and,

Time, t=2.20 seconds.

Now by using equations of motion :

v= u+at

0=12.5 m/s+a(2.20 s)

a=-12.5/2.20

a= -5.68 m/s

Now distance traveled will be :

v²-u²= 2as

0-(12.5 m/s)²= 2(-5.68 m/s)²×s

s= -156.25/-11.36

s= 13.76 meters.

Hence, the acceleration of the car was -5.68 m/s² and it travelled 13.76 meters before stopping.

By ideal gas approximation, container A has a higher temperature than container B.

We need to know about the ideal gas theory to solve this problem. The ideal gas is assumed that there is no interaction between particles in a gas. It can be determined by the equation

P . V = n . R . T

where P is pressure, V is volume, n is the number of moles gas, R is the ideal gas constant (8.31 J/mol.K) and T is temperature.

From the question above, we know that

PA = PA

nA = 2nB

When the initial and final pressure is the same, we can use the ratio of moles and temperature as

nA / TA = nB / TB

substitute nA

2nB / TA = nB / TB

TA = 2 TB

A circular loop of wire carries a constant current. If the loop is placed in a region of the uniform magnetic field, the net magnetic force on the loop is zero.

In an electric loop, the current-carrying wire creates a magnetic field that is perpendicular to the direction of the current.

Now let's suppose there are two diametrically opposite objects as shown in the figure below.

As the current is moving in the opposite direction, therefore, the effect of forces will cancel out each other due to  

dF =i( dl × B ).

It is because the magnetic field is perpendicular to the plane of the loop.

Thus, all forces will cancel out their effect and the net force on the loop will be zero.

Potential energy of a body that is due to its position. To be more precise, the potential energy of a body of mass 'm' at height 'h' will be -

P[E] = mgh

Kinetic Energy of a body is the energy due to virtue of its motion. Mathematically -

K[E] = 1/2 mv²

Given is a image of a roller coaster ride and a table describing the energy magnitude theoretically.

As mentioned, Potential energy of a body that is due to its position and is given by - P[E] = mgh. Let's complete the energy table given -

1 → Location with least potential energy

From the formula -

P[E] = mgh

mg = constant

P[E] [tex]\alpha[/tex] h

Now, the point 2 represents the minimum height, therefore Point 2 is the location with least potential energy.

2 → Location with most potential energy

We know -

P[E] [tex]\alpha[/tex] h

The point with maximum height is 1, therefore it will represented by Point 1.

3 → Conversion of potential to kinetic energy

Assume that the velocity of the roller coaster is v. Now at point 1, the velocity will be zero. Therefore, the total energy of the roller coaster will be purely potential energy. When it starts to move from point 1 to point 4, its height will decrease and its velocity will increase. Therefore - at this stage (point 4), the potential energy will start to convert into kinetic energy.

4 → Conversion of kinetic to potential energy

Use the same concept discussed in part - 3. In this case it is moving from lower point to higher point. So, height will increase and velocity will decrease. Therefore, the point 3 represents the stage at which kinetic energy will start to convert into potential energy.

Therefore, the complete table representing the energy description at different stages is

Least Potential Energy                                  [2]

Most Potential Energy                                    [1]

Yes, we can compute by using stokes' theorem always.

By merely knowing information on the values of F along the border of S, Stokes' theorem states that we can compute the flux of curl F across surface S. On the other hand, by converting to a double integral of the curl of F over S, we may get the line integral of vector field F along the edge of surface S.

Let S be an N-unit normalized smooth surface that is orientated. Additionally, let's assume that S has a simple closed curve C as its border. If the surface is constantly on your left while you walk in the positive direction around C while directing your head in the direction of N, then the orientation of S induces the positive orientation of C.
