Which of the following graphs has a slope that indicates an object whose velocity is zero

The correct option is 1.

Step-by-step explanation:

We need to find a graph that indicates an object whose velocity is zero.

Velocity is the change in displacement with respect to time.

Let d represents displacement and t represent time.

Velocity is 0.

It means the slope of line must be 0.

A horizontal line has slope 0.

In option 1, the graph represents a line whose slope is 0. It means displacement is 0 for any interval of time. So, velocity is 0.

Therefore the correct option is 1.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
