The flow of an alternating current switches direction when a generator's terminals change its charge is true regarding current in an external circuit

<u>Explanation: </u>

Two types of currents, one of them is direct current (DC), constant charging current in one direction. The current in the DC circuits shifts in a constant direction. The amount of electricity can vary, but it always flows from one point to another.

Next is alternating current (AC), the movement of the electric charge periodically changes direction. It is the form most often provided to enterprises and households. The usual form of AC wave is the sine wave. Some applications use different wave-forms, e.g. B. triangular or square waves.

Explain why fishes survive in ponds even when the temperature is below 0°c
zmey [24]

Answer:

After sufficient thickness of ice is formed it prevents further loss of heat from the bottom layers of water. This is why fishes and other aquatic animals and plants can survive in ponds and other water bodies even when the atmospheric temperature reaches or is well below 0 degrees.The anomalous expansion of water helps preserve aquatic life during very cold weather. When temperature falls, the top layer of water in a pond contracts becomes denser and sinks to the bottom. ... Thus, even though the upper layer are frozen, the water near the bottom is at 4°C and the fishes can survive in it easily.

kramer
<span>If there isn't any force then the normal contact force will be 


N=m*g=7.5*9.81=73.58N 

which is 73.58-23=50.58N less 

so, there the person must pull at 23 degree upward 

break down the tension in two components, vertical and horizontal. 


vertical tension= 50.58=T*sin23 

T=50.58/sin23=129.45N</span>
