A girl delivering newspapers covers her route by traveling 3.00 blocks west, 4.00 blocks north, and then 6.00 blocks east. What
borishaifa [10]

Answer:

13 blocks

Explanation:

The total distance the student travels is 13 blocks.

 Distance is the length of path covered during the motion of a body.

 To find distance:

 Total distance  = Number of blocks to the west + number of blocks to the north + number of blocks to the east

 Total distance  = 3blocks + 4blocks + 6blocks  = 13blocks

7.5 h
Julli [10]

The distance traveled by plane flying at 1200 Km/h for 2.5 hours is 3000 Km.

Velocity is a vector quantity. It has both a direction and a magnitude. Speed is used to calculate the magnitude of velocity. The meter per second is the S.I. unit for this. The units km/h and km/s are additional units. [LT-1] is the dimensional equation for it.

The distance traveled by the object is calculated as the product of the velocity with which it was moving and the time interval for which the distance covered is calculated.

Distance traveled =  Velocity × Time

Given in the question

Velocity of the plane = 1200 Km/h

Time Traveled = 2.5 h

Put in the value, we get

Distance traveled =  1200 × 2.5

Distance traveled = 3000 Km

Hence, the distance traveled by plane flying at 1200 Km/h for 2.5 hours is 3000 Km.

Examples of structure or machine parts that may fail due to bending​
Alex_Xolod [135]

Answer:

<em>Structural failure is initiated when a material is stressed beyond its strength limit, causing fracture or excessive deformations; one limit state that must be accounted for in structural design is ultimate failure strength.</em><em><u>Compressive, tensile, bending and buckling are the basic types of structural failure for construction elements. These are caused due to faults in design and construction</u></em>
