Because upward buoyant force is slightly higher than gravitation force for this particular object
Explanation:
Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage.
He will swim 180m if he stays at a constant rate of 30m/min
Explanation:
First I’m going to use 6 min for the 5min 60s
Then if he swims 30m/min then I’m 6min, 30•6 he’ll swim 180m
Hope this helps!
The distance travelled by the wave from the device to the sunken ship and back again will be 450 m
<h3>What is wave?</h3>
A wave is a phenomenon that flows across a material medium without leaving any lasting mark. Transverse and longitudinal are the two main forms.
The distance by the wave to travel the two-sided motion is,2x
Distance = speed ×Time

Hence, the distance travelled by the wave from the device to the sunken ship and back again will be 450 m
