Answer:
Explanation:
Galaxies are moving closer
Answer: 0
Explanation:
Given that:
Distance walked per day = 1 mile
Starting position = front of house
Final position = front of house(initial position).
In other to aid understanding; Displacement simply refers to the shortest or least distance measured from an individual's initial position to his final point.
Here,
Assume, front of house = point A
Then , initial position = point A (front of house)
Final position, = point A (front of house)
Hence, the shortest distance between final and initial positions is :
Point A - Point A = 0
Since, starting point is the same as the final point, then Displacement = 0
Answer: I belive that the Answer is C.) Conduction
Explanation:
Answer: Truck 2, because it has a larger mass than truck 1 (and the same velocity)
Explanation:
We can write the kinetic energy of an object with mass M and velocity V as:
K = (M/2)*V^2
Let's calculate the kinetic energy for each truck:
Now, we can see that both trucks move at the same velocity, but truck 1 has a mass of 5000 pounds, while truck 2 has also a mass of 5000 pounds and an extra of 900 pounds.
Then the total mass of truck 2 is 5000 pounds + 900 pounds = 5900 pounds.
Then both trucks have the same velocity, and truck 2 has a larger mass than truck 1, this implies that truck 2 will have a larger kinetic energy than truck 1.
Answer: B. Allegheny plateau
Explanation: Allegheny plateau is a mountainous region that makes up the northern part of the United States of America, the following states are located on the Allegheny plateau New York, Pennsylvania, West Virginia and Ohio, it is made up of HORIZONTAL SEDIMENTARY BEDROCK at elevated lands. Allegheny plateau is over 40million area is over 40million acres,it has been a site for Erosion and for millions years,through this erosions some areas have been brought low while others are higher following the deposition of materials by the erosion.
