Answer:

1. The "contour interval' 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 elevation. Elevation is the highest point in the area.

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

A racecar driver steps on the gas, and his racecar travels 20 meters in 2 seconds starting from rest. The acceleration of the ra

givi [52]

Answer:

2.5m/s^2

Explanation:

Step one:

given

distance = 20meters

time = 2 seconds

initial velocity u= 0m/s

let us solve for the final velocity

velocity = distance/time

velocity= 20/2

velocity= 10m/s

$v^2=u^2+2as\\\\10^2=0^2+2*a*20\\\\100=40a$

divide both sides by 40

$a= 100/40\\\\a=10/4\\\\a= 5/2\\\\a= 2.5m/s^2$

SashulF [63]

Answer: Technician B

Explanation: In manual cars,the clutch safety is designed to stop the vehicle from moving when you start the gnition. It prevents power from flowing into the circuit . This is found in the pedal mechanism of cars so depressing the clutch pedal will likely cause a defective in the clutch safety. You will begin to perceive the clutch burning and white fumes coming out from the pedal.

57. Example of the law of force and acceleration

7nadin3 [17]

Answer:

Newton's Second Law of Motion says that acceleration (gaining speed) happens when a force acts on a mass (object). Riding your bicycle is a good example of this law of motion at work. Your bicycle is the mass. Your leg muscles pushing pushing on the pedals of your bicycle is the force.
