Answer: A driver must not drive a vehicle at such a slow speed ... When driving under adverse weather, road or traffic ... before the school bus stops to pick up or let off students
Explanation:
hope this helps :)
a. Speed is defined as rate of change of distance per unit time whereas velocity is defined as rate of change of displacement per unit time.
b. is the total time taken in the trip
c. is the total distance
d. towards right from the starting point.
e.
f. towards right.
Explanation:
a.
Speed is a scalar quantity while velocity is a vector quantity.
Speed is defined as rate of change of distance per unit time whereas velocity is defined as rate of change of displacement per unit time.
Speed is a directionless quantity while velocity constitutes direction.
b.
<em>Total time of round trip when we're given:</em>
- distance travelled to the right,
- speed while travelling to the right,
- time spent at gas station,
- time spent while travelling back towards the left,
- speed while travelling to the left,
<em>Now time taken for travelling towards right:</em>
<u>Therefore total time taken in the round trip:</u>
c.
<em>Now, distance travelled towards left:</em>
<u>Therefore total distance:</u>
d.
Now, total displacement:
towards right from the starting point.
e.
<u>Average speed:</u>
f.
<u>Average velocity:</u>
towards right.
Distance= speed x time
distance = 2.6 m/s x 120s
distance= 312 meters
Answer:
They can figure out when the person died, possibly the nature of crime, it can also detect if the body was moved in certain area.
Explanation:
Answer:
-8
Explanation:
sea level is another way of saying zero. If something is above or above sea level it is a positive integer. like a regular number. if something is below sea level it is a negative integer like negative numbers. They said 8 is the elevation but new orleans is BELOW sea level. that means the integer we are looking for is going to be a negative number. 8 is the number they told us and since it is below the sea level. The integer of new orleans that represents its elevation is -8.
