Answer:
The path of an object in uniform motion is a straight line.
Hi!
The correct answer is: C. It is the data value that appears the most often in the set.
<h3>
Explanation</h3>
The mode of a set of values is the number which is the most frequently appearing, or most repeating value in the range. The numbers that show one time each are
A - 16 , C - 25 , D - 3
While 13 appears three times with the dishes labelled
B , E and F
So, the value that appears the most times is 13, and hence 13 is taken as the mode of this data set

Answer:
The distance at which nose of the vehicle will the shock wave impinge upon the ground is approximately 23km
Explanation:
Let
u be Mach angle
M be Mach Number = 2.5
h be altitude = 10km
d be distance between nose of the vehicle with which the shock wave impinge upon the ground
Using;
Sin u = 1/M
u = arcSin (1/M)
u = arcSin (1/2.5) = 23.58°
Using angle at a point rule = 90°
90 - 23.58 = 66.42°
Tan A = opp/adj
Tan 66.42° = d/10
2.2911 * 10 = d
d = 22.911km ≈ 23km
Centripetal acceleration is applied in circular motion. Y is the point on the track that most closely resembles a circular path for the roller coaster.
