Answer:
The total distance is equal to the change in total position of the person, but the displacement of the person is zero.
Explanation:
- The distance is the total change in the positions of the toy robot. it is having only magnitude and it is a scalar quantity.
- The displacement is the difference between the final and initial position of the toy robot. it is a vector quantity having magnitude and direction
- Since the distance is the change in positions, so the magnitude of the distance will be equal to the up and down distance covered.
- If the toy robot travels in a straight line path and returns back to its original location, the magnitude of the distance and displacement doesn't depend on the speed of the toy robot.
Answer:
Un átomo neutro siempre tiene el mismo número de electrones que los protones. Los electrones tienen una carga de -1 y los protones tienen una carga de +1. Por lo tanto, las cargas de los electrones y protones de un átomo "se cancelan". Esto explica por qué los átomos son neutros a cargo.
Answer:
c(t)= 40t
Explanation:
As it forms the right angle triangle. see attachment for the figure.
We will use Pythagoras theorem i.e
a² + b² = c²
where,
'a' is perpendicular
'b' is base
'c' is hypotenuse i.e the distance D between the ships in terms of the time 't'
the distance 'a' from the starting point is 24t
the distance 'b' from the starting point is 32t
therefore,
(24t)²+ (32t)² = c(t)²
c(t)= √(24t)²+ (32t)²
c(t)= √576t² + 1024t²
c(t)=√ 1600t²
c(t)= 40t
Thus, function that models the distance D between the ships in terms of the time t (in hours) elapsed since their departure is 40t
