<em>Answer: </em>

1. The <em>"contour interval'</em> identifies the standard difference in elevation on a topography graph. It shows the difference in elevation of highest and lowest points on a topography map.   In topographic map every fifth contour line is drawn, wider than the contour lines, called as contour index.


2. Geologist usually study all the materials that make up the earth. He can focus on different rock samples from earth's surface. the geologist works to understand history of the planet where we live on, to predict the future by explaining current occurrences.


3. The difference between the top of the plateau and the lowest point in the area of 250 m measurement is called <em>elevation. </em><em>Elevation is the highest point in the area.</em>


<em>4. </em>Damage from earthquakes is determined by <em>"Ritcher scale"</em>. Seismic waves are the vibrations occurs from earthquakes that can travel through the earth. These vibrations can be detected by the Ritcher scale.

Simple planetary gearsets are being discussed. Technician A says any one of the three members can be used as the driving or inpu
Alex17521 [72]

Answer: Technician A- any of the three members can be used as the driving or input member.

Explanation: The three members which can be used as a driving or input member are sun gear, pinion gear carrier, and ring gear, hence, the carrier and its pinions are seen as one unit which is the mid-size gear member. However, One member can be held and kept from rotating while the third member becomes the output member or the driven. Selecting which member is driving, held and driven determines the gear ratio for the gearset.

pav-90 [236]
The liquid in a thermometer is sometimes colored alcohol but can also be a metallic liquid called mercury. Mercury and alcohol expand when heated and shrink when cooled. Inside the glass tube of a thermometer, the liquid has no place to go but up when the temperature is hot and down when the temperature is cold. That's how a thermometer that uses liquid to measure temperature.

You see an advertisement for a new free fall ride at an amusement park. The ad says the ride is 50 meters tall and reaches a spe
AlladinOne [14]

Explanation :

It is given that the ad says the ride is 50 meters tall and reaches a speed of 28m/sec at the bottom.

The efficiency is defined as the ratio of the output energy and the input energy.

In this case, the output energy is kinetic energy and the input is potential energy.

Output energy, E_k=\dfrac{1}{2}\times mv^2

Input energy,  E_p=mgh

Efficiency becomes :

E=\dfrac{1\times v^2}{2gh}

E=\dfrac{1\times (28\ m/s)^2}{2\times 9.8\ m/s^2\times 50\ m}

E=0.8

or

E=80\%

The ride is 80% efficient.

The acceleration due to grauity at
Andrew [12]

Answer:

La gravedad de la Tierra, denotada por {\displaystyle g}g, es la aceleración neta que se imparte a los objetos debido al efecto combinado de la gravitación (de la distribución de la masa dentro de la Tierra) y la fuerza centrífuga (de la rotación de la Tierra).2​3​

En unidades SI, esta aceleración se mide en metros por segundo al cuadrado (en símbolos, m/s2 o m·s−2) o de manera equivalente en newtons por kilogramo (N / kg o N · kg−1). Cerca de la superficie de la Tierra, la aceleración gravitacional es de aproximadamente 9.81 m/s2, lo que significa que, ignorando los efectos de la resistencia del aire, la velocidad de un objeto que cae libremente aumentará en aproximadamente 9.81 metros por segundo cada segundo. Esta cantidad a veces se conoce informalmente como pequeña {\displaystyle g}g (en contraste, la constante gravitacional {\displaystyle G}G se denomina gran {\displaystyle G}G).

La fuerza precisa de la gravedad de la Tierra varía según la ubicación. El valor "promedio" nominal en la superficie de la Tierra, conocido como gravedad estándar es, por definición, 9.80665 m/s2. Esta cantidad se denota de diversas maneras como {\displaystyle g_{n}}{\displaystyle g_{n}}, {\displaystyle g_{e}}{\displaystyle g_{e}} (aunque esto a veces significa el valor ecuatorial normal en la Tierra, 9.78033 m/s2), {\displaystyle g_{0}}g_{0} o simplemente {\displaystyle g}g (que también se usa para el valor local variable).

El peso de un objeto en la superficie de la Tierra es la fuerza hacia abajo sobre ese objeto, dada por la segunda ley de movimiento de Newton, o {\displaystyle F=ma}{\displaystyle F=ma} (fuerza = masa × aceleración). La aceleración gravitacional contribuye a la aceleración de la gravedad total, pero otros factores, como la rotación de la Tierra, también contribuyen y, por lo tanto, afectan el peso del objeto. La gravedad normalmente no incluye la atracción gravitacional de la Luna y el Sol, que se explican en términos de efectos de marea. Es una cantidad vectorial (física), cuya dirección coincide con una plomada.
