The average velocity of the car traveling south and later returned to the starting point is 0.

Average velocity is defined as the change in displacement per change in the time of motion.

Average velocity is calculated as follows;

[tex]v = \frac{\Delta x}{\Delta t} = \frac{x_2 - x_1}{t}[/tex]

Let the initial displacement of the car, x₁ = 20 m

Let the final displacement of the car, x₂ = 20 m (since the car returned to the starting point).

The average velocity is calculated as;

[tex]v = \frac{x_2 - x_1}{t} = \frac{20 - 20}{5} = 0[/tex]

Thus, the average velocity of the car traveling south and later returned to the starting point is 0.

Answer:

Good conducters of heat and electricity. High melting points. high density. malleable. Ductile.

Explanation:

Answer:

I = 1575 / 5000 = 31.5 % interest on investment

(1 + i)^18 = 1.315      where i interest is earned per year

One can use logs or

1 + i = 1.315^1/18  = 1.0153

So the annual interest rate is .0153   or 1.53%

Or

5000 (1 + i)^18 = 6575

(1 + i)^18 = 1.315

18 log (1 + i) =  log 1.315

log (1 + i) =  .006607

1 + i = 1.0153

i = .0153 = 1.53%

Answer:

A. The have horizontal velocity and vertical acceleration.

Explanation:

Projectiles move in a curved path because : ( A ) They have constant horizontal velocity and vertical acceleration

Projectiles move in a curved path due to constant horizontal velocity and vertical acceleration due to gravity that acts on it. Projectile movement starts when an object is thrown/projected into the air. The object thrown into the air will travel in a curved path  known as trajectory.

Hence we can conclude that Projectiles move in a curved path because They have constant horizontal velocity and vertical acceleration.

Answer:

Meteoroids

Explanation:

Meteoroids are significantly smaller than asteroids, and range in size from small grains to one-meter-wide objects. Objects smaller than this are classified as micrometeoroids or space dust.

The term by which an asteroid called is smaller than a couple of meters wide is a meteorite.

A meteorite is a small group of rocks and debris. They are made by the collection of dust and small pebbles. They are smaller than asteroids, and they are formed in outer space, and they fall on earth from outer space, and when they fall into the earth with that great speed, they attain heat.

Meteorites also consist of metals, like nickel, carbides, sulfides, etc. It has been said that in old times the meteorite that contain iron, fall into the earth and the iron from them melted into the core of the earth. They are of different shapes and sizes.

Thus, the term by which an asteroid called is smaller than a couple of meters wide is a meteorite.

Answer:

The first statement appears most accurate.

The last statement also appears accurate, but it does not preclude any contradictory evidence.

The following statements accurately describe a scientific law: There is no contradictory evidence in the current body of knowledge. It is a statement that is true in many, but not all, cases. It is an observation that has been made many times.

The other statements do not accurately describe a scientific law:

"It is an educated guess about how a process occurs" describes a scientific hypothesis or theory, not a law.

"Can be updated or rejected if any contradictory evidence is found" describes the nature of scientific theories, which can be revised or discarded based on new evidence, but laws tend to remain consistent.

Answer: Convection currents in the molten mantle cause the plates to slowly move about the Earth a few centimeters each year. Many ocean floor features are a result of the interactions that occur at the edges of these plates.

Explanation:

The convection currents can be seen in a crowd, in the ocean, and can also be felt underground.

A convection current simply means the process that has to do with the movement of energy from one particular place to another.

A convention current is also known as convection heat transfer. Convention currents are due to differential heating. This brings about the circulation patterns that are referred to as convection currents that can be found in the atmosphere, water, and the mantle.

At the equilibrium or balance point the meter stick stationary and the sum of the moments and forces acting on it is zero

Reason:

Known;

Length of the stick = 1 meter

Mass of the stick, m = 0.1 kg

Point the stick will balance when the dough is at one end = 0.33 m

Required:

How much mass does the dough have

Solution:

The meter stick is balanced when the clockwise moment and the anticlockwise moment about the balance point are equal

Let M, represent the mass of the dough, we have;

The center of mass of the meter stick = The 0.5 m point

Taking moment, we have;

Distance from the center of mas of the ruler to the fulcrum, d₁ = (0.5 - 0.33) m

Distance from the dough to the fulcrum, d₂ = 0.33 m

Clockwise moment, [tex]\mathbf{\sum M_{clockwise} }[/tex] = m × d₁

Anticlockwise moment, [tex]\mathbf{\sum M_{anticlockwise} }[/tex] = M × d₂

Therefore;

(0.5 - 0.33) × 0.1 = M × 0.33

Therefore, we get;

The mass the dough has, M = 0.0[tex]\overline{51}[/tex] kg = 51.[tex]\underline{\overline{51}}[/tex] grams

Answer:

definition: the moving of something from its place or position.

Explanation:

though moving around a track they will always end in the same place therefore there is no displacement from the beginning position

There is no displacement from the starting position because they will always wind up in the same place as they started.

Displacement is defined as the overall alteration of an object's location and motion direction. Displacement is recognized as a vector quantity since it takes into account both the direction of the motion and the magnitude of the changing position. Displacement may be zero, positive, or negative.

The initial and final positions are needed in order to calculate displacement because displacement does not provide comprehensive information on the full path length.

The displacement is the shortest distance from the starting point to the finish point, the athlete starts from the start line and reaches the finish line after running through the whole track, but the starting point and the finishing point are the same, so the displacement is zero.

Therefore, the displacement of the athlete running through the track is zero for a complete race.
