$V= \frac{\Delta S}{\Delta t} = \frac{5}{15} = \frac{1}{3} m/s$

Average speed = (distance covered) / (time to cover the distance) =

 (5m) / (15 sec) =

 (5/15) (m/s) = 1/3 m/s .

Average velocity =

 (displacement) / (time spent traveling) in the direction of the displacement

Average velocity = (5m) / (15 sec) left =

 (5/15) / (m/sec) left =

 1/3 m/s left.

A number without a direction is a speed, not a velocity.

The correct one is A. Technician Only.
The distribution of service information is regulated by United States Environmental Protection Agency.
According to the rules, all vehicle manufacturers are required to make their service information available for everyone online for 'reasonable prices'.
Because of this, vehicle manufacturers started discontinuing the paper format.

Which explains upwelling in the oceans?

Leokris [45]

Winds blowing across the ocean surface push water away. Water then rises up from beneath the surface to replace the water that was pushed away. This process is known as “upwelling.”

Upwelling occurs in the open ocean and along coastlines. The reverse process, called “downwelling,” also occurs when wind causes surface water to build up along a coastline and the surface water eventually sinks toward the bottom.

Water that rises to the surface as a result of upwelling is typically colder and is rich in nutrients. These nutrients “fertilize” surface waters, meaning that these surface waters often have high biological productivity. Therefore, good fishing grounds typically are found where upwelling is common.

The answers are:

bulb, motor, buzzer and swtich.

As seen in the picture attached,

The electric current leaves the battery passes through the bulb. It then travels through the motor, next through the buzzer and finally passes through the switch before returning to the battery.
