Answer : The device is a Flash light.

Explanation :

A device contains an electric circuit, powered by a battery, that provides light energy and heat energy. It is a Flash light.

It is a closed circuit powered by a battery. The LED or incandescent light bulb is the source of light in flash light.

It consists of a reflector, battery and a switch.

Hence, the correct answer is Flash light.

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.

A positive test charge q is released from rest at distance r away from a charge of +Q and a distance 2r away from a charge of +2
Svetradugi [14.3K]

Answer:

B. to the right

Explanation:

Given:

  • test charge +q
  • distance of the test charge from +Q, r
  • distance of test charge from +2Q, 2r

<u>Force on the test charge due to +Q:</u>

F_1=k.\frac{Q.q}{r^2}

<u>Force on the test charge due to +Q:</u>

F_2=k.\frac{2Q.q}{(2r)^2}

F_2=k.\frac{Q.q}{2r^2}

Since all the charges are positive here, so they will try to repel the test charge away. And the force due to charge +Q will be greater so initially the test charge will move rightwards away from the +Q charge.
