A car traveling in a straight line has a velocity of 6m/s at some instant. After 6.32s its velocity is 13.2m/s . What is the average acceleration in this time interval?

Answers

Answer 1

Answer: Average acceleration = (change in speed) / (time for the change) .

Average acceleration = (13.2 - 6) / (6.32) = 7.2 / 6.32 = about 1.139... m/s² .

Which climate might one expect for Europe?a. temperate
b. polar
c. arctic
d. tropical

Answers

temperate.

polar and arctic are the same thing, so they're eliminated.

you're left with beach weather or normal weather. Europe is not a big beach, so I'd go with normal, temperate.

a train is moving at 4.0 km/h. It accelerates at 60 km/h/s for 0.75 h. What is its speed by the of the 0.75 h

Answers

Answer:

49 km/h

Explanation:

60 km/h acceleration for 0.75 hours.

60 × 3/4 = 45 km/h

Take the acceleration and add it to the speed the train was already moving at:

45 + 4 = 49km/h

Answers

Answer:

Distance

Explanation:

Isometry preserves the distance while transformation is made in between metric spaces. When a metric space is mapped on to another or itself, the distance between two points remains same in the images in the mapped space as well. Example: rotation and translation.

Thus, isometry preserves the distance.

Answer:

distance
